Child Development and Pedagogy PYQs

Perception is the process through which we interpret and organize the received information so as to produce our conscious experience of objects and their relationship.

• We feel something in sensation when the stimulus is present and when the meaning is added to them it becomes perception.
• In this process, physical energy; such as light, sound waves, heat; emanating from objects is transformed by the concerned sense organs into a code and transferred to and interpreted by the brain.
• The line between the two terms sensation and perception, therefore, is somewhat arbitrary.
• The sensation typically refers to the direct reception and transmission of messages, whereas perception refers to the active process of integrating and organizing these sensations.

 

Hence, we conclude that giving the meaning to sensation on the basis of past experience is called Perception.

Intelligence Quotient is abbreviated as IQ. IQ is a measurement of a person’s intelligence and it is measured in number. The average IQ of a person is 100.

An individual’s Intelligence Quotient (IQ) is determined by the formula:

\({\bf{Intelligence}};{\bf{Quotient}};\left( {{\bf{IQ}}} \right) = \frac{{{\bf{Mental}};{\bf{Age}};\left( {{\bf{MA}}} \right);}}{{{\bf{Chronological}};{\bf{Age}};\left( {{\bf{CA}}} \right)}} \times 100\)

where Mental Age is based on your intellectual development.

Chronological Age is the number of years a person has lived.

Given: CA = 5 years∴80=MA10×100∴80=MA10×100

MA = 8 years

\(\therefore IQ = \frac{{{\bf{8}}}}{{5}} \times 100\)

IQ = 160

Hence, the IQ of a child will be 160 and the child IQ will lie in above 130 IQ Range and having the Very Superior Intelligence (Gifted).

Mental retardation, as a developmental disability, has attracted considerable public attention. Its general debilitating character has made it a distinct category of disability. Individuals with mental retardation, face considerable difficulty in their lives in adapting to the demands of day-to-day life.

Classification of Mental Retardation:

Based On IQ: There are mainly three methods of classification of mental retardation. They are medical, psychological, and educational. The psychological and educational classifications are more commonly and widely used than medical classifications. 

• Educational Classification: This system uses the term educable, trainable, and custodial depending on the educational needs of retarded children.
• The IQ ranges of educable mentally retarded (EMR), trainable mentally retarded (TMR), and the custodial mentally retarded (CMR) are given below:
• | Levels of MR | IQ Range of MR | Educators | | --- | --- | --- | | Mild Retardation | 50-70 | Educable Mentally Retarded | | Moderate Retardation | 35-50 | Trainable Mentally Retarded | | Severe Retardation | 20-35 | Custodial Mentally Retarded | | Profound Retardation | Below 20 | Custodial Mentally Retarded) |

Important Points

• Educable Mentally Retarded (EMR): The educable mentally retarded children are those who can be taught the basic academic subjects.
• Trainable Mentally Retarded (TMR): The trainable mentally retarded are those children who can be taught functional academics with an emphasis on self-help and vocational skills.
• Custodial Mentally Retarded (CMR): The custodial mentally retarded are those children who require constant and special care especially in a residential institution.

Hence, we conclude that the 35 – 50 IQ range is called a trainable IQ level of mentally retarded children. So the answer is 36-49.

Rorschach inkblot Test: Hermann Rorschach, a Swiss psychiatrist, devised the Rorschach Inkblot Personality test in 1921. This test is most frequently used for the projective test

• The test consists of a standard set of 10 cards with inkblots printed on them.
• The Rorschach test is a measure of both intellectual and non-intellectual personality traits.
• In the series of 10 cards five are achromatic, two cards are black and red, and the remaining three cards are polychromatic in combination of green, blue, orange and pink blots.
• Conducted by the examiner to determine important aspects of each response into a coding system under four categories; Location, Determinant, Content, and Popularity.
• It consists of the following categories of scoring the protocol:-
• Total number of responses (R)
• Human responses (H)
• Animal responses (A)
• Anatomical responses (At)
• Sex responses (Sex)
• Movement responses (M)
• Rejection of images (Rej.)
• Most typical responses (MT)
• Typical responses (T)
• Atypical responses (AT).
• In the test, the subjects are asked to simply state whatever each inkblot looks like to them.
• Responses are scored by the psychologists using predetermined categories, on key factors such as color and shape, movement.
• These blots are frequently used for personality description, diagnosis of mental disorders, and for behaviour predictions.
• The whole procedure of The Rorschach Test is a combined set of three components, viz., performance proper, inquiry, and scoring.

Hence, we conclude that Rorschach inkblot test is used to measured Personality traits.

Forgetting: Forgetting is a failure to retrieve information from long-term memory stores. Much of the information is lost but enough remains so that we have a sketchy record of our lives. Sometimes what we think is forgotten in real sense is not forgotten because it was never encoded and stored in the first place. 

Causes of Forgetting:  Many students complain that they do not remember the contents after attending the class or forget after reading .the text. This happens due to :

• Mental Conflict: Many times we forget as memory does not match events that had occurred. This happens due to the constructive processes i.e. during encoding, the to-be-remembered information, interference due to similar material.
• Under-learning, some information does not reach short term memory from the sensory register.
• Defective methods of remembering: Inadequate encoding and rehearsal, the information may not have been transferred from short term to long term memory.

NOTE: Desire to learn is helpful in remembering the information for the long term.

Hence, we conclude that the desire to remember is not the cause of forgetting.

Statistics: In the singular sense, Statistics refers to what is called statistical methods which means the science which deals with the techniques for collection, classifying, presentation, analysis, and interpretation of statistical/numerical data information. In simple language, it means the subject of Statistics like any other subject such as Mathematics or Economics. 

• This definition lays emphasis on five important aspects, which in fact, constitute the very scope of the subject called Statistics or Statistical Methods. These are:
• Collection of Data: In any statistical inquiry, the collection of data is the first basic step. They form the foundation of statistical analysis, and therefore utmost care should be taken in collecting data in Primary and Secondary form.
• Classification of Data: It follows editing. It involves arranging data according to some common characteristics.
• Presentation of Data: Presented the data in the form of diagrams and graphs to facilitate the understanding of various trends as well as the process of comparison of various situations.
• Analysis of Data: It is the most important step in any statistical inquiry. A major portion of this course in Statistics is devoted to the methods used for analyzing the collected data to derive some policy conclusions.
• Interpretation of Data: It is the last but very crucial stage of a statistical inquiry or investigation. It is a job in itself that requires a high degree of aptitude, skill, and experience.

Additional Information

 

Hence, we conclude that the science which deals with the methods of collecting, classifying, presenting, comparing, and interpreting numerical data is called Statistics.

Sir Cyril Burt, the distinguished psychologist, and educationist can be regarded as the pioneer investigator of the 'Educational quotient of the Backward Child'. His work on the Backward Child' is of prime importance.

• In- his book 'The Backward Child,' Burt reported his study. In the beginning, before reporting his work, he thought it useful to clarify and distinguish the term 'backward' from some other related terms like 'dull' and 'retarded'.
• Burt was the first who given the term 'Educationally quotient for backward children'.
• Burt's view regarding the term 'backward' refers to the Educational Age in relation to the Chronological Age.
• Children having an Educational Quotient of 85 or less could be regarded as Educationally Backward, according to his criterion.
• He states: "Educationally backward in the technical sense all those who in the middle of their school career would be unable to do the work of the class next below that which is normal for their age".

Hence, we conclude that Cyril Burt has given the concept of educational quotient for backward children.

Tests are devices to gather information through some specified tasks presented to individuals. We come across various types of tests in education e.g. oral, written and practical; group or individual; performance, etc. Sometimes 'examination' is also used to mean a device or a test. 

Key Points

Characteristics of Good Test: A good test should enable us to the achievement or ability accurately and economically. Here we take a good test - validity, reliability, and usability.

• Validity: A test is said to be valid if it measures what it is supposed to measure. Cronbach defines validity as "the extent to which a test measures what it to measure".
• Reliability: A test is reliable if it gives consistent results of measurement on its administration on different occasions. Pupils should score similar scores if the test is repeated. Its administration maybe after some gap of time and the condition is that pupils do not receive any further training of related test content.
• Usability: Usability refers to practicability - ease, and economy in terms of energy, time, and money. Usability means a test should be: easy to construct; easy in administrating; easy in scoring; easy in interpreting; and economic in terms of money and time.
• Objectivity: When a student's score on a test is based only on the student's answers and not on the personal biases of the scorer (or teacher), then the scoring is considered to be objective. This depends on the procedure of the scoring (and the type of item to be scored).

Hence, we conclude that aptitude is not a characteristic of a good test, it is a part of the personality.

Theory of Regression: It is a statistical process for estimating the relationships among variables. It includes many techniques for modeling and analyzing several variables when the focus is on the relationship between a dependent variable and one or more independent.

Key Points

Intelligence Theories: 

 

Hence, we conclude that the Theory of regression is not the theory of intelligence. It is a part of statistical analysis.

The correct answer is Salivary gland.

Explanation:

Gland: A gland is an organ which produces and releases substances that perform a specific function in the body. Glands are two types:

• Exocrine glands are the glands that secrete their product into a duct. 
• For example, the salivary gland secretes the saliva into the salivary duct.
• Endocrine glands are the glands that secrete their product directly into the blood. There are no ducts in endocrine glands. 
• For example Hypothalamus gland, Pituitary gland, Adrenal gland, Thyroid gland etc.

So, Salivary gland is not a ductless gland.

"Jean Piaget", a Swiss psychologist, is famous for his work on child development. He made a systematic study of cognitive development in his theory that is categorized in four stages.

Key Points

• According to Piaget, the second stage of cognitive development is the 'pre-operations stage' which lasts around 2 to 6 or 7 years of age.
• In this stage, the child faces problems with the concept of conservation and struggles with the idea of centration and irreversibility.

Characteristics of the Preoperational Period:

• Egocentrism takes place.
• Begin to think symbolically.
• Develops the skills of language acquisition.
• Begin to use words and pictures to represent objects.
• Learns to compare objects through external characteristics.

Hence, it could be concluded that according to Piaget, the second stage of cognitive development is the pre-operational stage.

 Additional Information

Refer to the image for conceptual understanding of the characteristics of other stages of Piaget's theory:

Physical development is regulated by a complex balance between the heredity/genetic constitution and the environmental factors, all interdependent. 

Key Points

Factors Influencing Physical Development

• Heredity Factors: Heredity refers to the genetic constitution of an individual which is established during conception. It is the property of organic beings by which offsprings have the nature and characteristics of parents or ancestors. The height of a child depends more on heredity, while the weight, though also influenced Physical and Motor Development by heredity.
• Environmental Factors: Though heredity and environment are closely inter-related and each human being at birth has a gene determined physical, mental, and biochemical potential. Environmental factors like nutrition, living standard, family surroundings, etc. This potential may not be reached because of environmental influences. Environment influences this potential only to a limited extent favorably or unfavorably.
• Health Factors: The children are highly vulnerable to the negative health consequences associated with many environmental exposures. Health factors like, physical exercise, sports, games, etc. These factors influencing the physical development of a child. These factors also influence the growth of an individual. So school should provide physical exercises and games for child physical development.

Hence, we conclude that all are the factors influencing Physical Development.

Intelligence Quotient is commonly known as IQ refers to the score of a standardized test that assesses and measures human intelligence.

• The first test to measure intelligence was developed by Binet and Simon in 1905.
• Terman in 1916 revised the test and devised the concept of Intelligence Quotient.
• An individual’s Intelligence Quotient (IQ) is determined by the formula given below,

\({\bf{Intelligence}};{\bf{Quotient}};\left( {{\bf{IQ}}} \right) = \frac{{{\bf{Mental}};{\bf{Age}};\left( {{\bf{MA}}} \right);}}{{{\bf{Chronological}};{\bf{Age}};\left( {{\bf{CA}}} \right)}} \times 100\)

• Where, Mental Age is based on intellectual development.
• Chronological Age is the number of years a person has lived.

Hence, it could be concluded that MA/CA × 100 is the correct formula to calculate IQ.

Additional Information

John Dewey: The work of Dewey (1933) is considered as the beginning of the study and application of reflection.

• For him, reflection is a kind of thinking, in the process of which one brings the subject to the forefront of the mind and gives serious thought to this.
• It is a process of manipulation of knowledge and its reprocessing towards the set goal, and so, it is goal-directed.
• One ‘thinks’ when in uncertainty or difficulty so as to solve the ‘perplexity’, and the process leads to testing through some action.
• Dewey believed that effective education through reflection should aim at ‘making sense of the world’, and therefore, this is related to experience.
• Learners are aware of and control their learning by active participation in reflective thinking.
• In the reflective experience in which the environment is used as the object of reflection.

Key Points

Dewey’s concept of reflective thought and action, depicted comprises five phases: 

• Disturbance and uncertainty
• Intellectualization
• Formation of Hypothesis
• Reasoning
• Hypothesis Testing.

Hence we conclude that John Dewey described 'reflective thinking'.

Inductive Reasoning is a way of proving a statement or generalizing a rule or principle by proving or showing that if a statement or a rule is true in one particular case, it will be true in cases, which appear in some serial order, and thus it may be applied generally to all such type of cases.

Important Points

The levels of inductive reasoning are below:

• Generalization: Inductive reasoning starts from particular facts or special examples and instances one can formulate generalized principles and conclusions in this type of reasoning.
• Observation: Inductive reasoning is called the 'Bottom-up' approach, moving from specific observations and measures to detect patterns and regularities, formulate some tentative hypotheses that can explore and end up developing general conclusions or theories.
• Experimentation: Experimentation is an essential feature of inductive reasoning. Experiments are artificially created or contrived situations designed to make certain observations under strictly controlled conditions. The objective sometimes is to mimic nature. This allows the complexity of natural phenomena to be simplified for step by step study.

Hence, we conclude that 'Imagination' is not included in the level of Inductive reasoning.

Forgetting: Forgetting is a failure to retrieve and retain information from long-term memory stores. Much of the information is lost but enough remains so that we have a sketchy record of our lives. Sometimes what we think is forgotten in real sense is not forgotten because it was never encoded and stored in the first place. 

Key Points

Causes of Forgetting:  Many students complain that they do not remember the contents after attending the class or forget after reading .the text. This happens due to :

• Many times we forget as memory does not match events that had occurred. This happens due to the constructive processes i.e. during encoding, the to-be-remembered information, interference due to similar material.
• Under-learning, some information does not reach short term memory from the sensory register.
• Defective methods of remembering: Inadequate encoding and rehearsal, the information may not have been transferred from short term to long term memory.

Additional Information

• Memory is the knowledge of a former state of mind after it has already once dropped from consciousness, or rather it is the knowledge of an event, or fact of which meantime we are not been thinking with the additional consciousness that we have thought or experienced before.
• Retention is part of memory to retain the information for a longer period of life.
• Thinking is the process of cognition that is related to memory.

Hence, we conclude that failure in retention and recall of learned content is forgetting.

Basic Instinct is an inherited or innate psychological disposition which determines its possessor to perceive or pays attention to, objects of a certain class, to experience an emotional excitement of a particular quantity upon perceiving such objects, and to act in regard to it in a particular manner, or at least, to experience an impulsive to such an action.

Characteristics of Basic Instinct

• The main characteristic of basic instinct is inborn and natural that is found in all living organisms.
• No one can develop in their later stages, it is an inborn talent or ability to feel the things that may be going to happen or not in near future.
• Instinct is a vibe, that can be negative and positive.
• The instincts are dominated by the pleasure principle (the chief characteristic of psychic energy) and are inherited.
• Basic instinct may undergo more or less serious failures to pass through certain stages of development called the fixation of the instinct.
• These instincts drive the satisfaction of which is the prime intention of mental activity are essentially somatic needs.
• These are basically connected with the preservation of self and of species, which may be considered as needs.
• The aim of basic instinct is the preservation of the individual and the species.
• The basic instinct cannot be localized to any region of the mind.

Hence, we can conclude that The main characteristic of basic instinct is that which is found in all organisms and it is inborn and natural.

Fundamental Rights and Education: Fundamental Rights of citizens given in our Constitution have established the spirit of equality and have helped to preserve individual liberty. The following articles in the category of Fundamental Rights have a special bearing on education in India.

• ARTICLE 21A - It grants the Right to Free and Compulsory Education to all the children the aged six to fourteen years in a manner as the State may, by law determine. Inserted by the 86^th Amendment in December 2002, this Article has accorded education the status of right for ensuring quality in educational expansion at the elementary level.

Key Points

• Insertion of Article 21A, making elementary education a fundamental right of all children between the age group of 6-14 years, Article 45 has been amended so as to restrict its scope to pre-primary education up to 6 years of age.

Additional Information

Other Articles:

• ARTICLE 45: Directive Principles of the State Policy in Article 45 under Part IV of the Constitution states that “the State shall endeavor to provide, within a period of ten years from the commencement of this Constitution, for free and compulsory education for all children until they complete the age of fourteen years”.
• ARTICLE l5 - This Article guarantees prohibition of discrimination on grounds of religion, race, caste, sex or place of birth by the State. It also ensures equality in educational opportunities in India.

 Hence, we conclude that Article 21 A  states that "the right to free and compulsory education for children between age group of 6 - 14.

Kretschmer was a German psychiatrist who on the basis of his observation of patients classified people into four types. He used the physical constitution and temperament for this purpose The four types he talked about included:

• Pyknic type
• Asthenic type
• Athletic type
• Dysplastic type

Let us briefly study each of these types:

 

Hence, we conclude that all are the main types through which Kretschmer has classified the persons.

Teacher Eligibility Test (TET): Teacher Eligibility Test known as TET is an Indian entrance examination for teachers. The test is mandatory for getting teaching jobs in government schools from Class I to Class VIII.

• The examination is divided into Paper-I (Primary) and Paper-II (Elementary).
• TET was introduced by the Govt of India to improve standards in teaching. It is conducted by the Central and State governments in India.
• The essential qualifications for a person to be eligible for appointment as a teacher in any of the schools referred to in clause (n) of section 2 of the RTE Act are that he/she should pass the Teacher Eligibility Test (TET) which will be conducted by the appropriate government by the guidelines framed by the NCTE.
• A candidate has to score over 60% to clear the eligibility test.

Key Points

Purpose of TET

• The main purpose of the Teacher Eligibility Test (TET) is to assess the candidate's aptitude for the profession.
• Recruiting teachers by evaluating the aspiring candidates’ academic brilliance.
• The main motto is to impart quality teaching.
• Assess the teachers who have adequate teaching competency and a positive attitude towards teaching or not.

Hence, we conclude that the purpose of TET is to measure the aptitude for the profession.
