CTET Paper 1 - 29th Jan 2023 (English-Hindi-Sanskrit) (Previous Year Paper)

The answer is 1) Emotional.

Key Points

• Emotional development is the domain of development that discusses aspects related to display of self-control, expression and understanding of feelings.
• It includes the ability to identify and express emotions, understand the emotions of others, and regulate one's own emotions.
• Moral development is the domain of development that discusses aspects related to right and wrong, and the development of a moral compass.
• Physical development is the domain of development that discusses aspects related to growth, motor skills, and health.
• Motor development is the domain of development that discusses aspects related to the development of fine and gross motor skills.

Therefore, the domain of development that discusses aspects related to display of self-control, expression and understanding of feelings is emotional development. So the answer is (1).

The correct statement about development is 3) Rate of development varies across individuals.

Key Points

• Development is a complex process that is influenced by a variety of factors, including genetics, environment, and experiences. As a result, the rate of development varies across individuals.
• Some children may develop more quickly than others, and some areas of development may progress more rapidly than others.

The other statements are incorrect.

• Development is not purely erratic, as it follows a general pattern of growth and change.
• It is also not highly discontinuous, as there is a certain amount of continuity from one stage of development to the next.
• Finally, development does not proceed from toe to head, as all areas of development are interconnected and influence each other.

So the answer is (3).

The correct statement is 4) Both heredity and environment impact development in a complex manner.

Key Points

Heredity and environment are both important factors that influence development. Heredity refers to the genetic information that is passed down from parents to offspring. Environment refers to the physical and social surroundings that a person is exposed to throughout their life.

The impact of heredity and environment on development is complex and can vary depending on the specific trait or behavior being studied. However, in general, it is believed that both heredity and environment play a role in all aspects of development.

Statements 1, 2, and 3 are incorrect.

• Statement 1 is incorrect because the impact of heredity and environment on development can be altered by factors such as nutrition, education, and exposure to toxins.
• Statement 2 is incorrect because environment can also impact development, even if a person has a genetic predisposition for a certain trait or behavior.
• Statement 3 is incorrect because heredity can also impact development, even if a person is exposed to a favorable environment.

Therefore, the correct statement is (4).

The correct answer is 3) Sensorimotor.

Key Points

Jean Piaget's theory of cognitive development proposes that children progress through four stages of development: sensorimotor, preoperational, concrete operational, and formal operational. The sensorimotor stage is the earliest stage, and it begins at birth and ends around the age of 2.

During this stage, children learn about the world through their senses and their motor skills. They learn about objects by touching, tasting, smelling, seeing, and hearing them. They also learn about cause and effect by interacting with their environment.

The other stages of cognitive development are:

• Preoperational stage: This stage begins around the age of 2 and ends around the age of 7. During this stage, children develop the ability to use language and symbols. They also begin to think more logically, but they are still egocentric and unable to see things from another person's perspective.
• Concrete operational stage: This stage begins around the age of 7 and ends around the age of 11. During this stage, children develop the ability to think logically about concrete objects and events. They also become less egocentric and more able to see things from another person's perspective.
• Formal operational stage: This stage begins around the age of 11 and continues into adulthood. During this stage, children develop the ability to think logically about abstract concepts and hypothetical situations. They also become more reflective and able to think about their own thinking.

Therefore, the earliest stage in Jean Piaget's theory of cognitive development is the sensorimotor stage. So the answer is (3).

The correct statement is 4) Children in concrete operational stage understand classification and seriation.

Key Points

Jean Piaget's theory of cognitive development proposes that children progress through four stages of development: sensorimotor, preoperational, concrete operational, and formal operational.

• The concrete operational stage begins around the age of 7 and ends around the age of 11. During this stage, children develop the ability to think logically about concrete objects and events. They also become less egocentric and more able to see things from another person's perspective.

• One of the key cognitive abilities that develops during the concrete operational stage is the ability to classify and seriate objects.

• Classification is the ability to group objects together based on common properties. Seriation is the ability to arrange objects in order from smallest to largest or from shortest to tallest.

• Children in the concrete operational stage are able to classify and seriate objects without difficulty. They can also understand the concept of conservation, which is the understanding that the amount of a substance stays the same even if it is rearranged.

Therefore, the correct statement is (4).

The answer is 1) Pre-conventional.

Key Points

Lawrence Kohlberg's theory of moral development proposes that people progress through three levels of moral reasoning: pre-conventional, conventional, and post-conventional.

• The pre-conventional level is the earliest level, and it is characterized by a focus on rewards and punishments. People at this level believe that actions are right or wrong based on whether they will be rewarded or punished.

• Anil's behavior of directing most of his actions in a way that earns him rewards from his parents suggests that he is at the pre-conventional level of moral reasoning. He is motivated by the desire to be rewarded, and he does not yet understand the concept of right and wrong beyond its relationship to rewards and punishments.

Therefore, Anil is likely to be at the pre-conventional level of moral reasoning.

Additional Information

The other levels of moral reasoning are:

• Conventional: This level is characterized by a focus on social norms and expectations. People at this level believe that actions are right or wrong based on whether they conform to the norms and expectations of society.
• Post-conventional: This level is characterized by a focus on universal principles of right and wrong. People at this level believe that actions are right or wrong based on whether they uphold these principles, regardless of the consequences or the norms of society.

The answer is 1) Social interactions.

Key Points

Lev Vygotsky was a Russian psychologist who proposed that social interactions play a critical role in the development of thought among children. He argued that children learn through a process of scaffolding, in which they are guided by more knowledgeable others as they attempt to solve problems.

• Vygotsky's theory is often contrasted with the theory of Jean Piaget, who argued that children's cognitive development is driven by their own individual explorations. However, Vygotsky believed that both social interactions and individual exploration are important for cognitive development.

​Therefore, Lev Vygotsky emphasized social interactions for the development of thought among children.

Additional Information

The other options are incorrect.

• Genetic maturation is the process by which genes are expressed over time, and it is not a direct factor in the development of thought.
• Classical conditioning is a type of learning in which a neutral stimulus is paired with a rewarding or punishing stimulus, and it is not a major factor in the development of thought.
• Drill and practice is a method of learning in which students repeat a task over and over again, and it is not a particularly effective way to develop thought.

The correct statement is 2) Providing cues and hints fosters learning.

Key Points

Lev Vygotsky's theory of cognitive development is known as the sociocultural theory. It emphasizes the importance of social interactions in the development of thought. Vygotsky believed that children learn through a process of scaffolding, in which they are guided by more knowledgeable others as they attempt to solve problems.

• One way that scaffolding can be done is by providing cues and hints. Cues are small bits of information that can help children solve a problem. Hints are more general suggestions that can help children think about a problem in a new way.
• Vygotsky believed that providing cues and hints can foster learning because it helps children stay within their zone of proximal development. The zone of proximal development is the difference between what a child can do independently and what they can do with help. When children are provided with cues and hints, they are able to solve problems that they would not be able to solve on their own.

Therefore, the correct statement is 2) Providing cues and hints fosters learning.

Additional Information

The other statements are incorrect.

• Statement 1 is incorrect because discussions and debates can help children learn by providing them with different perspectives on a problem.
• Statement 3 is incorrect because private speech among children is a form of self-regulation that helps them solve problems.
• Statement 4 is incorrect because Vygotsky believed that learning is a social process that is facilitated by interactions with others.

The correct answer is 4) From rote memorisation to discovery learning.

Key Points

Behaviorism is a learning theory that emphasizes the importance of rewards and punishments in shaping behavior. Constructivism, on the other hand, is a learning theory that emphasizes the importance of active learning and discovery.

• Rote memorization is a learning strategy that involves simply memorizing facts and information without understanding them. Discovery learning is a learning strategy that involves actively exploring and experimenting with new information in order to understand it.

Therefore, in order to shift practices of your school from behaviorism to constructivism, you would want to move from rote memorization to discovery learning.

Therefore, the correct answer is 4) From rote memorisation to discovery learning.

Additional Information

The other options are incorrect.

• A flexible curriculum allows for more student-centered learning, while a standardized curriculum is more teacher-centric.
• Formative assessment is used to provide feedback on student learning, while summative assessment is used to measure student learning.
• Exam-centric pedagogy focuses on preparing students for exams, while teacher-centric pedagogy focuses on the teacher as the primary source of knowledge.

The answer is 2) Interpersonal.

Key Points

Gardner's theory of multiple intelligences proposes that there are eight different types of intelligence, including interpersonal intelligence. Interpersonal intelligence is the ability to understand and relate to other people. People with high interpersonal intelligence are good at reading social cues, understanding the emotions of others, and building relationships.

• The student in the question is very good at interpreting the intentions, motivation level, and moods of their classmates. This suggests that they have high interpersonal intelligence.

Therefore, the student in the question has interpersonal intelligence.

Additional Information

The other options are incorrect.

• Naturalist intelligence is the ability to understand and appreciate the natural world.
• Logical intelligence is the ability to think logically and solve problems.
• Spiritual intelligence is the ability to understand and connect with one's own spirituality.

Key PointsIn Jean Piaget's theory of cognitive development, the term "operations" refers to mental actions or processes that individuals use to manipulate and transform information mentally. These operations involve mental activities such as thinking, reasoning, problem-solving, and understanding the world around us.

• Piaget proposed that as children grow and develop, they go through distinct stages of cognitive development. One of the key milestones in this development is the acquisition of operational thinking, which occurs during the concrete operational stage (around ages 7 to 11) and continues to develop in the formal operational stage (from around age 11 and onward).
• During the concrete operational stage, children become capable of performing mental operations on concrete objects and events. For example, they can mentally reverse actions or transformations, conserve quantities and perform logical operations such as classification and seriation.
• As they move into the formal operational stage, their operational thinking becomes even more sophisticated. They become capable of abstract thinking and can reason about hypothetical situations and concepts, allowing them to engage in advanced problem-solving and deductive reasoning.

Overall, the concept of "operations" is fundamental to understanding how individuals develop their cognitive abilities and how their thinking becomes more advanced and flexible over time according to Piaget's theory.

Key Points

• The statement "Boys are always good at mechanics and girls are good at embroidery" represents gender stereotyping. Gender stereotyping is the practice of assigning certain characteristics or roles to people based on their gender.
• In this case, the statement is suggesting that boys are naturally good at mechanics and girls are naturally good at embroidery. This is a harmful stereotype because it limits the opportunities of both boys and girls. It can also lead to discrimination and prejudice.

Additional Information

• Gender equity, gender equality, and gender parity are all related concepts, but they have different meanings. Gender equity is the state of being fair and just in terms of the distribution of resources and opportunities between men and women.
• Gender equality is the state of being equal in terms of rights, responsibilities, and opportunities between men and women. Gender parity is the state of having equal numbers of men and women in a particular group or situation.

Key PointsTeacher-centric pedagogies do not cater to individual differences of students' learning preferences: This statement is correct as,

• Teacher-centric pedagogies are centered around the teacher's delivery of information without much consideration for individual learning differences.
• In contrast, student-centric or learner-centered approaches aim to tailor instruction and activities to accommodate the diverse learning preferences and needs of students, leading to more effective and personalized learning experiences.

Additional Information

• All learners prefer the same style of acquiring skills: This statement is incorrect. Individual learners have different learning preferences, styles, and strengths.

Some may prefer visual learning, others auditory or kinesthetic learning. Recognizing and accommodating these differences can enhance learning outcomes.

• Learning preferences are not impacted by socio-cultural factors: This statement is incorrect. Socio-cultural factors, such as a learner's cultural background, upbringing, and social environment, can significantly influence their learning preferences.
• Standardized curriculum comprehensively accounts for individual differences in learning preferences: This statement is incorrect. Standardized curricula typically follow a one-size-fits-all approach, which may not effectively cater to the diverse learning preferences of individual students.

Key Points

• Formative assessment is an ongoing process in education that involves gathering information and feedback about students' learning progress during the instructional period.
• It is designed to inform and improve the teaching and learning process rather than determining final grades or outcomes.
• Formative assessment helps teachers like Iram monitor how well students are grasping the material, identify areas of strength and weakness, and make necessary adjustments to their instructional methods to support students' learning needs.

Additional InformationHere are some of the benefits of using formative assessment:

• It can help teachers identify students who are struggling and provide them with additional support.
• It can help teachers adjust their instruction to meet the needs of all students.
• It can help students track their own progress and identify areas where they need to improve.

Key Points

• Critical thinking is the ability to think clearly and rationally about a problem or issue. It involves the ability to identify and evaluate information, draw conclusions, and solve problems.
• To promote critical thinking among students, a teacher should create a learning environment where students are encouraged to ask questions, challenge assumptions, and think for themselves. This can be done by:
• Providing opportunities for students to engage in open-ended inquiry. This means giving students problems or questions that do not have a single right answer.
• Encouraging students to formulate plausible hypotheses. This means asking students to come up with possible explanations for a phenomenon or event.
• Teaching students how to evaluate information. This means teaching students how to identify reliable sources of information, how to assess the credibility of information, and how to distinguish between fact and opinion.
• Creating a culture of open discussion and debate. This means encouraging students to share their ideas and to respectfully challenge the ideas of others.

In summary, promoting a learning environment that encourages students to formulate plausible hypotheses and ask questions will foster critical thinking skills, enabling students to think independently, analyze information, and arrive at well-reasoned conclusions.

Key Points

• An inclusive culture is one that welcomes and respects all students, regardless of their background. This means recognizing and celebrating the diversity of students, and providing opportunities for all students to succeed.
• Respect for diversity is essential for creating an inclusive culture. This means valuing the different cultures, experiences, and perspectives of all students.
• Flexible curriculum is also important for creating an inclusive culture. This means having a curriculum that is adaptable to the needs of all students.
• Ignorance of individual differences and focus on performance-oriented goals are not conducive to creating an inclusive culture. Ignoring individual differences can lead to students feeling excluded or marginalized.
• A focus on performance-oriented goals can also lead to students feeling pressured to succeed, which can be counterproductive for students from diverse backgrounds.

Therefore, the only options that promote an inclusive culture are (i), (iv).

Dyspraxia, also known as Developmental Coordination Disorder (DCD), primarily causes challenges in physical coordination.

Key Points

• It is a neurological condition that affects a person's ability to plan and coordinate movements, resulting in difficulties with fine and gross motor skills.
• People with dyspraxia may struggle with activities such as tying shoelaces, buttoning clothes, handwriting, and participating in sports or other physical activities.
• While dyspraxia can impact various aspects of a person's life, its most direct challenge is related to physical coordination and motor skills.

Hence, 'Dyspraxia' causes direct challenges in physical coordination.

Key Points

• Students with visual impairment rely on their sense of touch and hearing to navigate their environment.
• Frequent changes in the arrangement of furniture and other physical objects can make it difficult for them to orient themselves and can lead to accidents.

Additional Information 

• Providing a microphone for voice clarity can help students with visual impairment to hear the teacher's voice more clearly.
• Using multimedia teaching can help students with visual impairment to access information in a variety of ways.
• Using tactile teaching aids can help students with visual impairment to learn by touch.

Hence, by avoiding frequent changes in the arrangement of furniture and other physical objects, and by using the other strategies listed above, teachers can help to create an inclusive learning environment for students with visual impairment.

Key Points

Autism spectrum disorder (ASD) is a developmental disorder that affects communication and behavior. People with ASD may have difficulty with social interaction, communication, and repetitive behaviors. They may also be sensitive to sensory information, such as light, sound, touch, taste, and smell.

Here are some of the characteristics of people with ASD that are related to sensory sensitivity:

• They may be hypersensitive to certain sensory stimuli, such as bright lights, loud noises, or certain textures. This can be overwhelming and uncomfortable for them.
• They may be hyposensitive to certain sensory stimuli, such as pain or temperature. This means that they may not feel pain or temperature as much as other people do.
• They may seek out certain sensory stimuli, such as spinning or flapping their hands. This can help them to regulate their sensory input and to feel more comfortable.
• Sensory sensitivity can be a challenge for people with ASD, but it can also be a strength. For example, people with ASD who are hypersensitive to sound may be able to hear things that other people cannot hear. This can be an advantage in some situations, such as when they are trying to track down a source of noise.

Key Points

• Gifted students are typically characterized by their advanced cognitive abilities, creativity, and motivation.
• They often have a strong desire to learn and explore new ideas, and they are often very precise in their thinking. They may also be more likely to ask questions and challenge the status quo.

Here are some other characteristics of gifted students:

• Advanced cognitive abilities: Gifted students typically learn new concepts quickly and easily. They may also be able to think abstractly and solve complex problems.
• Creativity: Gifted students often have a unique way of thinking and approaching problems. They may be able to come up with new and innovative solutions.
• Motivation: Gifted students are often highly motivated to learn and achieve. They may set high goals for themselves and work hard to achieve them.

Teaching-learning materials (TLMs) are resources used in the educational process to enhance and facilitate teachers' instructional practices and students' learning experiences. 

Key Points

• The most appropriate sequence for teaching a concept in primary grades is first present concrete objects then pictures of objects.
• This sequence follows a concrete-to-representational approach, which is often effective in helping young learners understand abstract concepts.
• Starting with concrete objects allows students to interact with and manipulate tangible items, which helps build a strong foundation for understanding.
• Once students grasp the concept with real objects, they can transition to representations like pictures to bridge the gap between the concrete and the abstract.

Hint

• Rest options do not follow the typical progression of moving from the concrete to the abstract, which may not be as effective for young learners who are still developing their conceptual understanding.

Hence, we can conclude that the most appropriate sequence for teaching a concept in primary grades is first present concrete objects then pictures of objects.

Competition among students can lead to a focus on grades or rankings rather than the intrinsic value of learning and might discourage cooperation and community within the classroom.

Key Points

• Emphasizing competition among students might create an environment where success is seen as outperforming peers, rather than achieving personal understanding or growth.
• Making content relevant to students' lives and interests helps them see the value and importance of what they're learning.
• Collaborative learning encourages students to work together, share ideas, and learn from one another.
• Presenting information in a context that students can relate to helps them understand and apply concepts.

Hence, we can conclude that Competition among students should not be emphasized to enhance students' engagement in learning.

Constructivism is a theory of learning that emphasizes the active role of the learner in building understanding and making sense of information.

Key Points

• In the constructivism approach, learners actively construct their own knowledge by connecting new information to existing knowledge, often through hands-on exploration, inquiry, and interaction with their environment.
• Psychoanalytic: Focuses on unconscious processes and early childhood experiences, not typically related to the active construction of knowledge through exploration and interaction.
• Behaviorist: It doesn't generally focus on the learner's active exploration and construction of knowledge but rather on conditioning and reinforcement.
• Functionalist: It looks at societal functions but doesn't usually describe the process of individual learners actively constructing knowledge through exploration and interaction.

Hence, we can conclude that the constructivist approach to learning considers learners as active beings who are capable of constructing new knowledge through explorations and interactions with their surroundings.

Functional fixedness is a cognitive bias that limits a person to using an object or concept in only the way it is traditionally used.

Key Points

• It can inhibit creative thinking and problem-solving, making it harder for students to apply what they've learned in new or unconventional ways.
• This doesn't generally facilitate learning, especially in subjects that require creative or critical thinking.
• Encouraging students to make predictions can engage them in the learning process and help them actively think about the material, connecting it to what they already know.
• Creating visual representations of information and how concepts are related can help students understand complex ideas and see how different parts of a subject are connected.
• This strategy can help students understand what a concept is not, clarifying their understanding by contrasting examples with non-examples. It can be a helpful part of the learning process.

Hence, we can conclude that Functional fixedness does not facilitate learning.

Problem-solving is the process of finding a solution to a problem. It is a complex skill that requires a variety of cognitive abilities.

Key Points

• It is important to encourage students to explore multiple possible solutions because it helps them to develop their problem-solving skills.
• When students explore multiple solutions, they are more likely to find the best solution and they are also more likely to learn from their mistakes.
• Heuristics are shortcuts or "rules of thumb" that can sometimes help in problem-solving, especially in complex or time-pressured situations.
• Avoiding scaffolding may hinder the learning process for many students, particularly those struggling with certain concepts or skills.
• Avoiding opportunities for reflection may limit growth in problem-solving abilities.

Hence, we can conclude that a teacher should encourage students to explore multiple possible solutions.

Seema's insistence on considering the "tap" as the foremost source of water is a reflection of her understanding based on her direct experience and observation at her age.

Key Points

• This understanding represents her 'naive' theory as per her experience.
• It's not uncommon for young children to develop these "naive" theories based on their direct observations, even though they may not align with scientific understanding.
• Discarding it without discussion misses an opportunity for teaching and could dismiss the child's effort to make sense of her world.
• While it may not be scientifically accurate, labeling it as "highly erroneous" might not capture the developmental aspect of her thinking.
• Her idea has a basis in her daily experience and observation, so it's not without foundation or purely irrational.

Hence, we can conclude that Her alternative conception of the source of water represents her 'naive' theory as per her experience.

The relationship between emotions, motivation, and cognition is well-recognized in educational research, and many educators consider students' emotional states in their teaching methods.

Key Points

• Assertion (A): Considering the emotional state of students can help teachers better connect with students and adapt their teaching to meet students' needs.
• Emotions can significantly impact a student's ability to learn, concentrate, and engage with the material.
• Reason (R): Emotions are indeed closely linked with motivation and cognition. Emotional states can affect a student's motivation to learn and their cognitive processing abilities.

Hence, we can conclude that Both (A) and (R) are true and (R) is the correct explanation of (A).

Key Points

• Performance-approach goals are focused on demonstrating one's competence by outperforming others. This goal orientation is characterized by a desire to win, get good grades, or be the best at something.
• Individuals with a performance-approach goal orientation are motivated by the need to feel good about themselves and to be seen as competent by others.
• The statement "Learning to prove superiority over peers" indicates that the individual is motivated to learn in order to outperform others. This is a clear example of a performance-approach goal orientation.

Additional Information

• Mastery-approach goals are focused on learning and mastering new skills, while mastery-avoidance goals are focused on avoiding doing worse than one has done before.
• Performance-avoidance goals are focused on avoiding looking incompetent or less able than others.

A conducive learning environment refers to a setting or atmosphere in which students feel physically and emotionally safe, supported, engaged, and inspired.

Key Points

• One of the most important things that a teacher can do to create a conducive learning environment is to know and express respect for students' sociocultural backgrounds.
• This means understanding the different cultures and experiences that students bring to the classroom and being sensitive to those differences.
• When teachers understand students' sociocultural backgrounds, they are better able to connect with them and to create a learning environment that is relevant and meaningful to them.
• This can help to improve students' motivation and engagement, and it can also help to reduce conflict and misunderstanding.

Hence, we can conclude that it is important for a teacher to know and express respect for students' socio-cultural background.

Key Points

• Learning is a complex process that involves the acquisition of new knowledge, skills, and abilities.
• It is an active process, in which the learner actively constructs knowledge by interacting with the environment.
• Social interactions play an important role in the learning process, as they provide opportunities for learners to share ideas, collaborate, and learn from each other.

Additional Information

• Learning is an active process of knowledge construction: This means that learners do not simply absorb knowledge passively, but rather they actively build new knowledge by interacting with the environment and making sense of their experiences.
• For learning to take place, some level of readiness among students is required: This means that learners need to be motivated and have the prerequisite knowledge and skills in order to learn effectively.
• Learning is effective when acquired through active involvement of learner: This means that learners are more likely to learn effectively when they are actively engaged in the learning process, rather than simply listening to lectures or reading textbooks.

Calculation:

⇒ 11000 + 1100 + 11 - x = 10000

⇒ 11000 + 1111 - x = 10000

⇒ 12111 - x = 10000

⇒ x = 2111

∴ The correct answer is 2111.

Calculation:

⇒ 8668 + 6888 + 8868 + x = 33110

⇒ x = 33110 - 24424 = 8686

∴ The correct answer is 8686.

Given:

Shweta has 5 red dots and 7 green dots inside her ring.

Kanta has 4 red dots and 12 green dots inside her ring.

Calculation:

Points scored by shweta = 5 × 5 + 7 × 1 = 25 + 7 = 32

Points scored by kanta = 4 × 5 + 12 × 1 = 20 + 12 = 32

Both shweta and kanta got equal points.

∴ The correct answer is option 4.

Calculation:

Statement 1 is true because there are an infinite number of natural numbers, and any natural number greater than 1 can be factored into a product of prime numbers.

Statement 3 is true because a prime number by definition has only two factors, 1 and itself.

Statement 4 is true because the only prime number between 90 and 100 is 97.

Statement 2 is false because there are prime numbers that are even. The smallest even prime number is 2.

Therefore, the correct answer is 2.

Calculation:

⇒ \(9 \frac{3}{4}+3 \frac{1}{2}\) 

⇒ 39/4 + 7/2 

⇒ 53/4

Now divide 53/4 by 1/4

⇒ 53/4 × 4/1 = 53

∴ The correct answer is 53.

Calculation:

In the Indian number system, a million is equal to 10 lakh.

Therefore, 12 million is equal to 12  × 10 lakh = 120 lakh.

120 lakh can also be written as 1 cr 20 lakh.

So, the answer is 1 crore 20 lakh.

Concept used:

A line of symmetry is an imaginary line that divides a shape into two halves that are mirror images of each other. If you can fold a letter in half and the two halves match exactly, then the letter has a line of symmetry.

Calculation:

The letters B, X, and T all have one line of symmetry. The letter S does not have any line of symmetry.

∴ The correct answer is option 3.

Calculation:

A regular polygon is a polygon in which all the sides and all the angles are equal. This means that all the sides are the same length, and all the angles have the same measure.

∴ The correct answer is option 4.

Calculation:

Angle traced by minute hand = (360° / 60 minutes) × 45 minutes = 270°

∴ The correct answer is option4 .

Calculation:

According to question,

Tapan buys, 1 kg potato, 0.5 kg onion, 250 g carrot, 100 g chillies, 4 lemons

Total cost = 30 + 17.5 + 20 + 25 + 20 + 20

⇒ 132.5

Now Money he will get back = 500 - 132.5 = 367.5

∴ The correct answer is 367.5.

Given:

Bottle is 1/3^rd full.

Calculation:

According to question,

⇒ 1 part is filled and rest 2 part is empty.

Now, 2 part = 500 ml

⇒ 1 part = 250 ml

⇒ 3 part = 250 × 3 = 750 ml

Total Capacity = 750 ml

∴ The correct answer is 750 ml.

Given:

Journey Started = 16 : 45

Journey Finished = 23 : 10

Concept:

1 hour = 60 minutes

Journey Completion Time = Journey Finished - Journey Started

Calculation:

Journey Completion Time = Journey Finished - Journey Started

= 23 : 10 - 16 : 45 = (22 + 1 hour) ∶ 10 - 16 : 45

⇒ 22 ∶ (60 + 10) - 16 : 45

⇒ 22 ∶ 70 - 16 : 45

⇒ 6 hours 25 minutes

Calculation:

Logic = number × number²

So the next term will be,

⇒ 5 × 5² = 5 × 25 = 125

∴ The correct answer is 125.

Calculation:

Tally marks are a way of representing the frequency of a data set. They are used to count the number of times each value appears in a data set. This information can then be used to create a frequency table or histogram.

Mean, median, and maximum and minimum number are all measures of central tendency. They are used to describe the center of a data set. Tally marks are not used to find these measures.

∴ The correct answer is option 4.

Calculation:

According to question,

The number of rabbits are little less than double the number of rabbits in previous year.

⇒ 10 × 2 = 20 > 18

⇒ 18 × 2 = 36 > 32

⇒ 32 × 2 = 64 > 58

⇒ 58 × 2 = 116 > 108

∴ The correct answer is option 4.

The skill of reciting tables typically comes after a basic understanding of number concepts, and is part of early arithmetic skills, not pre-number skills.

Key Points

• Pre-number skills include abilities such as classification (grouping similar objects), ordering (arranging objects in a sequence), and one-to-one correspondence (matching objects from one group to another).
• These skills lay the foundation for understanding numbers and arithmetic.
• Once a child understands the concept of multiplication (that it is essentially repeated addition), they may start learning multiplication tables. For example, they learn that 2x2 equals 4, 2x3 equals 6, and so on.
• Reciting tables is a practice that helps children to internalize these multiplication facts so they can recall them quickly and accurately, which can be very helpful as they progress to more complex mathematical problems.

Hence, it can be concluded that option 4 is the correct answer.

At the primary level, using concrete, hands-on materials like circular cut-outs and rectangular strips can be very effective in introducing the concept of equivalent fractions.

Key Points

• This approach can be especially powerful because it provides a visual way to understand the concept.
• For instance, you might show a child that if you cut a circular pie into two equal parts, each part is 1/2 of the whole.
• Then, if you further cut each half into two equal parts, you now have four parts, and each is 1/4 of the whole. Yet, two of those 1/4 pieces make up the same amount as one 1/2 piece - showing that 1/2 is equivalent to 2/4.
• In contrast, the other options involve mathematical procedures or concepts (multiplication and division of fractions, least common multiple) that are generally more abstract and are typically introduced at a later stage than equivalent fractions.

Hence, it can be concluded that option1 is the correct answer.

While this method can work to demonstrate the concept of negative numbers, it might be more difficult for learners to understand, especially at an introductory level, because it lacks a tangible or visual representation. 

Key Points

• Understanding this requires a conceptual leap: it involves abstract thinking and an understanding of the symbolic representation of "owing" or "less than zero", represented by the negative number.
• The equation 12 - 28 = -16 is demonstrating the idea that if you have 12 of something and you try to take away 28, you end up "owing" 16, hence the result of -16.
• The negative sign is used here to show a deficit or a condition of "less than zero".
• It's important to note that while the subtraction method may be less appropriate initially, it's still a valid and important context that students will need to understand as they continue to learn about negative numbers and other mathematical concepts.

Hence, it can be concluded that option 3 is the correct answer. 

Additional Information 

• Temperature going down below 0°C: This is a relatable example where temperatures can fall below zero, indicating colder conditions. Negative numbers represent degrees below zero.
• Floors in a multi-storey building below ground level: This is another practical example where floors can be below ground level (basements or parking garages), represented by negative numbers.
• Account of a shopkeeper which shows profit and loss: This is a real-life scenario where negative numbers could represent a loss or debt in business or economics.

Mathematics is a language that strives to be as unambiguous as possible.

Key Points

• It is characterized by precision, conciseness, and the use of symbols to represent concepts, relationships, and operations in a manner that can be universally understood.
• The purpose of this is to minimize misunderstanding or interpretation errors.
• Mathematical language strives to be the exact opposite of this - it aims to be clear, exact, and unambiguous.

Hence, it can be concluded that ambiguity, which indicates uncertainty or the possibility of multiple interpretations, is not a characteristic of mathematical language. Instead, clarity and precision are key attributes.

The National Curriculum Framework (NCF), 2005, by NCERT in India, emphasizes a constructivist approach to education, focusing on creating an environment where each child can actively participate, engage with meaningful problems, and see the subject (in this case, mathematics) as part of their daily life.

Key Points

1. A teacher engages every child in posing and solving meaningful problems in mathematics.

• ​​In this approach, the teacher plays the role of a facilitator, making sure every student is involved in the process of learning.
• They are not just passively absorbing information, but actively participating, posing questions, and solving problems.
• The problems given to students are meaningful - they are designed to deepen students' understanding of mathematical concepts and to demonstrate the practical application of these concepts in the real world.

2. Children see mathematics as a part of their daily lives and something to discuss.​​

• This highlights the importance of relating mathematical concepts to real-life situations.
• This approach aims to show students that mathematics is not an isolated, abstract subject, but something that is integral to our everyday lives.
• It could be as simple as counting change, measuring ingredients for a recipe, or understanding the time.

Hence, it can be concluded that option 3 is the correct answer.

The student's error in writing "three hundred six" as 3006, instead of the correct 306, suggests a misunderstanding of place value. In the decimal number system, each digit's position signifies its value.

Key Points

• The correct writing of "three hundred six" should have 3 in the hundreds place and 6 in the one's place, with 0 in the tens place, hence 306.
• This doesn't necessarily mean that the student doesn't know how to count or read, nor does it imply that their answer is correct.
• It mainly shows a specific misconception or gap in understanding the place value system, which is a crucial concept in arithmetic and number theory.

Hence, it can be concluded that option 2 is the correct answer.

Key Points

• At the Analysis level, students are able to break down shapes into component parts, analyze relationships between parts, and compare properties.
• They start to explore more complex geometric relationships and properties beyond simple recognition and categorization.
• If the teacher is asking students to sort shapes into different groups based on the properties of the shapes and assess their understanding of relationships and properties, then it aligns with the Analysis level of geometric thinking according to Van Hiele's theory.

Hence, it can be concluded that option 4 is the correct answer.

While solving problems, getting good marks, and remembering certain formulas and shortcuts can be part of learning mathematics, the primary focus should be on developing a deep conceptual understanding and the ability to reason logically.

Key Points

• For instance, it could include multiple-choice questions, open-ended problems that require written responses, and practical tasks.

Hence, it can be concluded that a diagnostic test is the correct answer.

The National Education Policy (NEP) 2020, released by the Government of India, has set a target of achieving universal foundational literacy and numeracy in primary schools by 2026-2027.

Key Points

• This initiative aims to ensure that all children across India acquire essential reading, writing, and arithmetic skills during their primary school years.
• Foundational literacy and numeracy refer to the basic skills of reading, writing, and arithmetic that are the building blocks for further learning.
• This includes, for example, the ability to read and understand simple texts, write coherently, and perform basic mathematical operations.

Hence, it can be concluded that option 2 is the correct answer.

The child's error seems to be more related to understanding the measurement of angles rather than using the protractor, since they drew an acute angle (60°) instead of the required obtuse angle (120°).

Key Points

• They might be confusing the concept of acute and obtuse angles. The remediation should, therefore, focus on correcting this misconception.
• This activity helps to conceptualize the size and orientation of an obtuse angle.
• Then, the child uses a protractor to draw the actual 120° angle.
• By comparing the sketch with the actual protractor-drawn angle, the child can recognize their estimation accuracy, adjust their mental image of obtuse angles, and comprehend the measurement aspect better.
• This two-step, compare-and-learn process is effective in consolidating knowledge about different types of angles and their measurements.

Hence, it can be concluded that option 4 is the correct answer.

Real life examples like time tables, railway charts, and surveys provide rich, diverse, and practical contexts for teaching the concept of data handling.

Key Points

• By analyzing and interpreting these data sources, students can better understand how data is organized, represented, and used in everyday life to make decisions and predictions.
• This hands-on approach not only makes the subject more engaging but also helps students appreciate the importance and applicability of data handling in real-world situations.

Hence, it can be concluded that the intention of the teacher is to give the real life context of 'Data-Handling' to children.

The misconception the child is demonstrating is about comparing fractions, not understanding that a smaller denominator means a larger fraction, assuming the numerators are equal.

Key Points

• Visual representation can help the child understand that 1/4 is less than 1/3.
• For example, the teacher could draw two circles, divide one into 4 equal parts and color one part (1/4), and divide the other into 3 equal parts and color one part (1/3). The child would visually see that 1/3 is larger than 1/4.
• Giving the definition of unit fractions might be useful as background knowledge, but it might not directly help the child understand why 1/4 is less than 1/3.
• Teaching how to calculate the Least Common Multiple (LCM) might be useful for comparing fractions with different denominators. However, in this specific case (1/4 and 1/3), it's not necessary and might confuse the child more.
• Teaching the comparison of natural numbers would be useful in general, but it wouldn't directly address the child's misconception about comparing fractions.

Hence, it can be concluded that option 1 is the correct answer.

While solving problems using given formulas can help learners apply specific mathematical techniques, it may not contribute significantly to developing their mathematical reasoning skills.

Key Points

• Mathematical reasoning involves understanding the underlying principles and logic behind mathematical concepts, making connections between different ideas, and applying critical thinking to solve problems in various contexts.
• Relying solely on given formulas may limit learners' ability to think creatively and develop a deeper understanding of the subject matter.
• Therefore, it is essential to combine formulaic problem-solving with activities that encourage generalizations, exploration of different solution methods, and comparisons to foster mathematical reasoning effectively.

Hence, it can be concluded that option 2 is the correct answer.

The most effective way to help a student overcome misconceptions is for the teacher to understand the student's thinking process and reasoning towards the concept.

Key Points

• This can be achieved through one-on-one discussions, asking the student to explain their thought process, and identifying the specific points of confusion.
• Once the teacher understands the misconceptions, they can then design targeted interventions, explanations, and activities to address and correct the student's understanding.
• Encouraging students to talk about their reasoning and addressing misconceptions in a supportive and constructive manner will lead to better conceptual understanding and improved mathematical performance.
• It's important for teachers to create a safe and encouraging environment where students feel comfortable expressing their thoughts and asking questions about the concepts they find challenging.

Hence, it can be concluded that option 4 is the correct answer.

The correct answer is decreases and the amount of moisture in air (humidity) is high.

Key Points

• When the wind speed decreases, the rate of evaporation also decreases, leading to slower cooling.
• High humidity means that the air already contains a high amount of moisture, which reduces the rate of evaporation and slows down the cooling process.
• When both wind speed and humidity are low, the air is relatively dry and has a higher capacity to absorb moisture, leading to a faster rate of evaporation and cooling.

Additional Information

• Wind speed is a crucial factor in the rate of evaporation as it helps to remove the moisture-saturated air from the surface, allowing more dry air to come into contact with the surface and absorb moisture.
• Humidity is the amount of moisture present in the air, and it affects the rate of evaporation by determining how much moisture the air can still absorb.
• Other factors that affect the rate of evaporation include temperature, surface area, and the type of liquid or material being evaporated.
• Understanding the factors that affect evaporation is essential in various fields such as meteorology, agriculture, and manufacturing, where controlling the rate of evaporation is critical to achieving desired outcomes.

Invite village community to a school play showing drawbacks of child marriage: This option takes a community-based, awareness-building approach.

• Organizing a school play to showcase the drawbacks of child marriage can be a powerful tool for education and initiating conversations within the community.
• It addresses the issue at a broader level by encouraging a shift in social norms and attitudes.
• It considered the most suitable because it not only raises awareness but also engages the community in a non-confrontational manner.
• By using a creative medium like a school play, Aparna can effectively convey the negative consequences of child marriage and potentially influence community perspectives.

In summary, addressing child marriage requires a community-centric, culturally sensitive approach that aims to change societal attitudes. Option 4 aligns with this approach, making it a more suitable choice in the given context.

Hint

• Talking to the parents alone might not always be effective, as child marriage could be deeply ingrained in cultural norms and traditions in the village.
• Contact village panchayat representative and prevent marriage: In many Indian villages, the panchayat plays a significant role in community matters. Involving them can be more culturally sensitive than directly involving the police. However, the effectiveness depends on the attitudes and practices of the specific panchayat.
• Informing the police can be considered as a last resort if other efforts fail, as child marriage is illegal in many countries, including India. However, it is generally better to address the issue through community involvement and awareness first, as involving the police can sometimes have unintended consequences.

Environmental Studies (EVS) is a subject that encourages active learning, exploration, and engagement with the environment and the world around us. It is essential to use methods that promote experiential learning and critical thinking to understand the complexities of environmental issues.

 Key Points

These approaches address the individual learning needs of the student and can significantly enhance their understanding and learning experience in EVS.

• Make a Mixed Peer Group while Learning: Creating a mixed peer group involves grouping students with different levels of understanding and abilities together. When students work in groups, they can learn from each other. Those who have a better grasp of the topic can help explain concepts to their peers, reinforcing their own understanding in the process.​
• Break the tasks into parts and teach the parts separately: Breaking down complex topics into smaller, more manageable parts can make it easier for the student to grasp the content gradually. By teaching the concepts step-by-step, the student can build a solid foundation and better understand the overall topic.

Thus, it is concluded that A and B is the correct answer.

The objectives of teaching Environmental Studies (EVS) can vary based on the specific goals of the curriculum or the educators.

 Key Points

• The most important objective of EVS teaching at the primary level is to help children develop conceptual understanding of the world around them.
• EVS encourages children to observe, explore, question, and construct meaning, which strengthens concept formation rather than memorization.
• NCERT EVS curriculum (Classes III–V) highlights “understanding” as the core purpose, where learning is built through experiences, discussion, and exploration.

Hint

• Developing conceptual knowledge - Knowledge is limited to facts; EVS goes beyond facts to help students understand concepts.
• Developing procedural knowledge - Procedural skills like “how to do” are important, but they are not the primary objective in EVS at the primary stage.
• Developing higher-order thinking skills - HOTS develop gradually, but at the primary level, the emphasis is first on building basic conceptual understanding.

Thus, it is concluded that the most important objective of Environmental Studies (EVS) teaching is developing conceptual understanding.

Learning indicators of EVS are specific observable behaviors or outcomes that demonstrate a student's understanding and knowledge of environmental concepts and their ability to apply them.

 Key Points

• Observation and reporting are crucial skills in EVS learning as they involve students actively engaging with their environment, making detailed observations, and reporting their findings.
• Through observation, students can gather firsthand information about various environmental phenomena, natural resources, ecosystems, and human interactions with the environment.
• By reporting their observations, they develop the ability to communicate their understanding, which is an essential aspect of learning and sharing knowledge in EVS.

Thus, it is concluded that Observation and reporting represents the learning indicators of EVS learning.

Key Points

The National Curriculum Framework (NCF) 1975 proposed that Environmental Studies be taught as a single, integrated subject for the entire primary stage.

• This meant that in classes I and II, both the natural and social environment would be covered under one subject.
• However, in classes III to V, the curriculum would be divided into separate portions for social studies and general science, labeled as Part I and Part II, respectively.

Additional Information

Here's a breakdown of the recommendations for Environmental Studies across different NCFs:

• NCF 1988: Similar to NCF 1975, it recommended Environmental Studies as a single subject for the primary stage, but with increased emphasis on environmental awareness and conservation.
• NCF 2000: This framework advocated for Environmental Studies to remain an integrated subject for the entire primary stage, highlighting the interconnectedness of natural and social environments.
• NCF 2005: This current framework reiterates the recommendation of NCF 2000, emphasizing the importance of integrated Environmental Studies throughout the primary stage.

Therefore, NCF 1975 stands out as the framework that proposed the specific division of Environmental Studies into separate portions for social studies and general science in classes III to V.

The given scenario describes a classic example of classical conditioning, which is a type of learning where a neutral stimulus becomes associated with a meaningful stimulus to produce a specific response.

Key Points

• In this case, the interval bell ringing (neutral stimulus) has become associated with the expectation of the mid-day meal (meaningful stimulus), which leads to joyful anticipation and salivating response (unconditioned response) in the children.
• Over time, the bell ringing becomes a conditioned stimulus that triggers the conditioned response of joy and mouthwatering, even without the actual meal being served yet.
• Classical conditioning was famously studied by Ivan Pavlov, and it is a fundamental form of learning that helps individuals and animals associate stimuli with certain responses based on previous experiences.

Thus, it is concluded that Classical conditioning is the correct answer.

Hint

• Observational learning involves learning by observing and imitating others.
• Operant conditioning involves learning through reinforcement and punishment, where behaviors are strengthened or weakened based on their consequences.
• Instrumental conditioning is another term for operant conditioning, emphasizing the use of behaviors as instruments to produce specific outcomes.

In Environmental Studies (EVS), teaching methods play a crucial role in enhancing students' understanding of the natural world. The chapter "Super senses" in class V focuses on the diverse ways animals, specifically birds, use their senses. When it comes to teaching about birds' warning calls, selecting an effective approach is important to engage students and facilitate a meaningful learning experience.

Key Points

​Taking students to a field visit and listening to calls by birds

• This approach is considered the most suitable as it provides a direct, experiential learning opportunity.
• Taking students to a field visit allows them to observe birds in their natural habitat and listen to their warning calls firsthand.
• This real-life experience deepens understanding and makes the learning process more memorable and authentic.

Additional Information

• Imitating different calls by teachers: While teachers can bring enthusiasm and engagement to the classroom, imitating bird calls might not provide an authentic representation. It could be challenging for teachers to accurately imitate various bird calls, and students may benefit more from experiencing the actual sounds in nature.
• Imitating different calls by students: This option involves student participation, which is generally positive. However, imitating bird calls might not be as effective as experiencing them in their natural context. Students might struggle to accurately mimic the sounds, and the focus may shift from understanding the purpose of warning calls to imitating the sounds themselves.
• Asking students to identify recorded calls: This option involves listening to recorded bird calls, which can be informative. However, it lacks the direct experience of being in the field and might not fully capture the nuances and context of the birds' behavior. Field visits provide a more holistic understanding of the environment.

In conclusion, option 4 stands out as the most suitable approach because it aligns with the experiential nature of Environmental Studies and allows students to directly engage with the subject matter in its natural setting.

School-based assessment (SBA) is an educational assessment approach that involves evaluating students' learning progress and achievements within the school setting.

 Key Points

• It is learner-centred: School Based Assessment (SBA) places the focus on the learner's progress, development, and individual needs. It emphasizes understanding the strengths and weaknesses of each student, tailoring instruction to their learning styles, and providing feedback to promote growth and improvement.
• It is diagnostic in nature: SBA is designed to diagnose students' learning progress, understanding, and challenges. It helps identify areas where students need additional support and allows teachers to adapt their instructional strategies accordingly. The diagnostic nature of SBA aims to enhance learning outcomes by addressing individual learning needs.

Thus, it is concluded that A and C is the correct answer.

Hint

• SBA is not teacher-centred; rather, it revolves around the learner's needs, progress, and achievements. The teacher's role is to facilitate and support the learning process.
• Its focus is on the evaluation of achievement: While SBA involves assessment and evaluation, its primary focus is on assessing student learning progress and diagnosing areas for improvement. It is not solely focused on the final achievement or grades but aims to promote continuous improvement and personalized learning experiences.

A unit plan is a comprehensive and detailed outline of instructional activities and assessments that a teacher designs to teach a particular topic or theme over a defined period, usually lasting for several weeks.

• A unit plan is a detailed plan that focuses on a specific subject matter or topic, which is a cohesive whole.
• It is designed to cover a particular theme or concept in-depth, often spanning multiple lessons or instructional periods.
• A unit plan can vary in the number of lessons it covers, and it is not limited to planning for more than 10 lessons.

Some unit plans may consist of just a few lessons, while others may extend to several weeks or even months, depending on the depth and complexity of the subject matter.

• While a unit plan does include an overview of the learning activities for the entire unit, it is not necessary to provide detailed activities for each individual lesson plan within the unit.
• It is a short-term plan that concentrates on a particular topic or concept within a subject area, aiming to achieve specific learning outcomes over a shorter time frame.

Thus, it is concluded that It is planning for a subject matter which is a cohesive whole is applicable for unit plan.

An integral component of Environmental Education at the primary level is children's environment.

 Key Points

• Environmental Education aims to help children understand and connect with their immediate surroundings and natural environment. It involves learning about the local environment, ecosystems, natural resources, and the impact of human activities on the environment.
• By engaging with and exploring their own environment, children can develop a sense of environmental awareness, responsibility, and appreciation for the world around them. It encourages them to be observant of their surroundings, recognize environmental issues, and participate in efforts to protect and preserve the environment.

Thus, it is concluded that children's environment is the correct answer.

Key PointsAccording to NCF 2005, the objectives of teaching Environmental Studies (EVS) at the primary level are:

• To develop an awareness about environmental issues: EVS aims to sensitize children to the importance of environmental conservation and sustainability. It focuses on developing an awareness of various environmental issues and the role that individuals can play in protecting the environment.
• To nurture the curiosity and creativity of the child, particularly in relation to the natural environment: EVS encourages children to explore and interact with the natural environment. It fosters curiosity about the world around them and promotes creativity in understanding and appreciating the natural world.
• To enhance children's learning capabilities by providing concrete learning experiences: EVS utilizes concrete learning experiences that are connected to the child's immediate environment. These experiences enhance the child's learning capabilities and understanding of various concepts related to the environment, society, and their interconnections.

Thus, it is concluded that A, B and C is the correct answer.

The discussion method is a teaching and learning technique that involves interactive and collaborative conversations between the teacher and students or among students themselves.

Key Points

• Involving interchange of ideas among peers: The discussion method involves active participation and interaction among students. It encourages students to share their ideas, opinions, and perspectives on a particular topic or issue. Through discussions, students learn from each other, exchange viewpoints, and engage in meaningful dialogue.
• Enhancing self-confidence in students: The discussion method provides opportunities for students to express themselves in a supportive and collaborative environment. As students engage in discussions, they develop self-confidence in articulating their thoughts and viewpoints. This can lead to improved communication skills and a greater sense of self-assurance.

Thus, it is concluded that C and D are the characteristics of discussion method.

The theme "Relationships" in EVS often involves exploring various relationships between living organisms, between humans and the environment, and between individuals and society.

Key Points Role play is a suitable method:

• Active learning: Role play allows students to actively participate and engage in the learning process. Through role play, they can step into different roles and perspectives, which helps them better understand and empathize with different relationships.
• Real-life connections: Role play provides opportunities to simulate real-life situations and relationships, making the learning experience more relatable and meaningful for students.
• Empathy development: By acting out different roles, students can develop empathy and a deeper understanding of how relationships impact individuals and communities.

Thus, it is concluded that Role play would be suitable for transacting the theme "Relationships" in EVS class.
