Thus, the final arrangement,

The field of child development is concerned with the changes in the behavior of children over time and explains why and how it occurs. Growth refers to organic changes and is usually quantitative in nature. Development refers to functional or non-organic changes and usually qualitative in nature.

Key Points

• The development of the child is primarily determined by two factors: Nature and Nurture.
• Nature and nurture play an important role in the development of the child.
• Nature refers to what people inherit-biological groundwork that prepares a person to develop in certain ways but nurture refers to environmental factors- what a person is exposed to in life.
• The development of fetus depends upon the availability of a nutritious diet to the mother.
• After birth, the family particularly the socialization practices and parent-child-relationship has great impact on cognitive, language, social and personality development.

Hence, we can conclude that Nature & Nurture are the two main effects on child development.

Moral dilemmas occur only when there is a conflict between two moral reasons. A moral reason is a moral requirement just in case it would be morally wrong not to act on it without an adequate justification or excuse. 

Lawrence Kohlberg studied moral development by posing moral dilemmas to groups of children as well as adolescents and adults.

Key Points

• These dilemmas take the form of stories, one of Kohlberg’s best-known dilemmas involves a man named Heinz, who must choose between stealing medicine and letting his wife die.
• Instead of the answer, Kohlberg analyzed the reasons children gave for their answers. He identified three general levels of moral reasoning: pre-conventional, conventional, and post-conventional, and described two stages at each level.
• The moral reasoning of preschool children was influenced by a concern for obedience and punishment and for satisfying personal needs. When children enter the stage of concrete operations, they are able to turn away from their egocentric thinking, growing more concerned about appearing ‘good’.

Therefore, a teacher can catch the thoughts of children towards morality by telling the same story of Heinz's dilemma and asking their opinion.

Constructivism: Constructivism is centered on the idea that human knowledge and learning are actively constructed by the learner, not passively received from the environment. Constructivist views learning as the result of mental construction. It is created or constructed by the experiencing individual. It is not impersonal or absolute.

Key PointsIn a constructivist classroom, however, the materials would be used by the children as an aid for them to explore the world and discover ideas through contexts that they relate to. This alternative was presented as the constructivist view of learning. Two essentials of this model of learning are the active participation of the child and the role of the teacher as a facilitator and encourager.  

• Learners are active participants in constructivist classrooms.
• A constructivist classroom always promotes group work and collaborative and cooperative learning.
• In the constructivist classroom, learning is done in a meaningful and effective manner, students can learn by making a mental image of the concepts.
• Tasks in the constructivist classroom are moderately difficult, which can be done by the involvement of all the learners.
• It doesn't promote rote learning or memorization.
• Learners in constructivist classrooms, learn by interacting with others.

Thus by all these references, we can conclude that learning is meaningful and effective if the teacher used a constructive approach to the learners.

Important Points

• Behavioristic learning: Behavioristic theories or Behaviorism constitute the traditional theories of Learning. These theories were propounded by Ivan Pavlov and John B. Watson. Behaviorists attribute learning to the association between stimulus and response. 
• Decontextualization is the Process of examining or interpreting something that is separate from the context in which it is embedded. "Decontextualization occurs consciously or subconsciously." The content and curriculum should be designed according to the laid principles of inclusive education.

Assessment is the qualitative description of an attribute, according to some standards of criteria.

• Measurement, Assessment, and evaluation go together in a teaching-learning process.
• Assessment is denoted using comparative words like more/less; greater/lesser; increased/reduced etc.

Key Points

•  Assessment of learning helps the learners, teachers, and others in the following ways:

1. it helps the teachers to redesign instructional objectives.
2. it helps teachers to make better evaluative judgments.
3. it helps curriculum constructors to examine whether the courses or topics included in the curriculum are properly planned, whether the chronology of content is maintained or whether any change or modification is needed.
4. it helps parents to know the progress of their children and the areas of difficulty and remediation needed.
5. it helps students to know their progress in learning and learning difficulties in different subject areas.
6. it helps children to be motivated and improve their learning habits.
7. For teachers, the form of grades and marks helps to compare the child with other students in the classroom and also to observe the learning changes from time to time in the child.

• In this way, the assessment of student learning plays an important role in strengthening the teacher-learning process.

Hence, it can be concluded that in learning, assessment is essential for the motivation of the learner.

Important Points

Informative Tools:

• These tools of ICT provide huge information in various formats such as text, sound, graphics, or video. Examples of informative tools include multimedia encyclopedias or resources available on the WorldWide Web (www or Web).
• You can use informative tools particularly to collect information. Although these tools cannot help to get the real-life experiences, it presents abstract information. Suppose you are going to teach the concept of democracy in social science.
• You may assign the students to collect information on the governance system of different countries. Students can collect different information on governance with help of the informative tools of ICT like the internet.

Additional Information

Situating Tools:

• There are some ICT tools like simulation, games, and virtual reality through which students can be placed in an environment where they may get “nearly direct experience” through observation or practice in an artificially created model of the real situation.
• These tools are particularly helpful to understand abstract concepts. Suppose you are going to teach the topic of the blood circulation system of human beings. Students will gain better experiences with the help of You Tubes, video clips, specially prepared DVDs, etc. where they can observe the moving streams of blood in the arteries and veins and functioning of the heart with details of the physiology of the blood circulation.

Constructive Tools:

• There are different tools of ICT that you can use for constructing, manipulating as well as visualizing your own knowledge. For example, the tools of ICT like web authoring applications allow creating one’s own web pages and communicating ideas to others around the world.
• Here your constructive ideas/information reaches throughout the world including peers and teachers. At the same time, you can also get feedback about your ideas from the learner community.
• Other examples of such constructive tools of ICT are Mindtools, which includes computer applications such as databases, spreadsheets, semantic networking programs, expert systems, modeling tools, microworlds, and hypermedia authoring tools that enable students to represent and to generate knowledge.
• The term “constructive” originates from the fact that these tools of ICT enable the production of a certain tangible product for a given instructional purpose.

Communicative tools:

• We communicate our ideas/ knowledge/views with the help of communicative tools. But many of them are time-consuming.
• Take the example of the postal system which takes more time for your information to reach. Although the telephonic device reduced the time its limitation is between two people.
• However today we can communicate with a large group of people within a few seconds by using ICT tools. Examples of such communicative tools include e-mail, electronic bulletin boards, chat, teleconferencing, and electronic whiteboards.
• Such communicative tools of ICT are called web-2.0. One of the important characteristics of such tools is a simultaneous conversation among a group of people in the form of text, picture, or sound.
• These tools are the systems that can enable communication between the teacher and students or among students beyond the physical barrier (due to space, time, or both) of the classroom.

Hence, we can conclude that the worldwide web is an example of the informative tool of ICT.

The curriculum is neither a document nor a sequence of experiences. It is a plan of facilitating learning for the learner. It includes aims, objectives, teaching content, teaching strategies, and all teaching-learning aids to cater totality of students' experiences that occur in the educational process.

• This plan starts from where the learner is, enumerates all the aspects and dimensions of learning that are considered necessary, gives reasons why such learning is considered necessary, and what educational aims it would serve.

Key Points

• ​The process through which an instructor or institution develops or accepts a course plan is known as curriculum development. Curriculum development is carried out in order to achieve educational goals.
• As a result, the curriculum is the vehicle for attaining educational goals. Time and energy are used wisely. It gives instructors and students recommendations on what a teacher should study.​
• The requirement of curriculum development is for knowing the needs of changing society and provide education for sustainable development (ESD). It improves learning in the cognitive, social, emotional, and behavioral dimensions.
• ESD equips students with the knowledge, skills, values, and attitudes they need to make informed decisions and take responsible actions for environmental integrity, economic viability, and society.
• Sustainable development is described as development activities that do not harm the environment and may be continued for an extended length of time. Living within natural resource consumption constraints is one of the key principles of sustainable development.
• "Education that allows every human being to acquire the knowledge, skills, attitudes, and values necessary to design a sustainable future" is how Education for Sustainable Development (ESD) is defined.

As a result, we can conclude that the requirement of curriculum development is for knowing the needs of changing society and provide education for sustainable development (ESD).

Socialization describes how a relatively defenseless human child develops into a self-aware, educated individual who is informed about and proficient in the customs of their community. Key Points

•  Sociologist Robert K. Merton coined the phrase "anticipatory socialization" (1957).
• It is a method through which someone is actively socialized in preparation for future jobs, roles, and interpersonal connections.
• People are socialised into groups through anticipatory socialization such that joining the group does not appear to be particularly difficult for them to accomplish. When it comes to preparing their children for future occupations or social responsibilities, some individuals contend that parents are the main source of anticipatory socialisation.
• For instance, A child is made to leave home to stay in a boarding school with the anticipation of better socialization.

Hence, it is concluded that A child is made to leave home to stay in a boarding school with the anticipation of better socialization. This is an example of anticipatory socialization.

The term “development” is generally used to refer to the dynamic process by which an individual grows and changes throughout its lifespan. It is often thought of as the process of qualitative change taking place from conception to death. It deals with all areas including physical, motor, cognitive, physiological, social, emotional, and personality.

Key Points

• Development is shaped by the joint influences of both nature and nurture in a cultural context. Both nature and nurture jointly influence development. 
• Nature refers to the hereditary contribution a child receives from parents at the time of conception. Genetics determines several aspects of a person’s physical structure and functioning as well as some psychological characteristics to a certain extent.
• Nurture refers to the influence of the environment on all of those same things and includes parenting style, physical surroundings, economic factors, and anything that can have an influence and development that does not come from within the person.

Thus by all these references, we can conclude that nature and nurture both affect an individual's development at a given time in children.

Additional Information Factors affecting the development of the child are:

• Genetically Determined Factors: most of the inherited characteristics are essentially influenced by the environment.
  • For example, a child may be endowed with the hereditary potential for physical growth, but his/her potential may be stunted due to various reasons such as lack of nutrition or illness or being forced to do too heavy work for the body.
• Non-genetically Determined Factors: There are many non-genital factors that affect the development of the child these are- 
  • Conditions in the Pre-natal Environment 
  • Maternal nutrition 
  • Maternal health
  • Nutrition
  • Physical  effects and illness
  • The Psycho-social Environment of family and Culture, and many more.

Adolescence

• Among humans, adolescence is a complex, multi-system transitional process involving progression from the immaturity and social dependency of childhood into adult life with the goal and expectation of fulfilled developmental potential, personal agency, and social accountability,
• In simple terms, adolescence is the phase between childhood and adulthood.
• It starts with puberty ( sexually mature) and ends when somatic growth is completed and is psychologically mature.

Important PointsEmotional development during adolescence

• Emotions have often been used to define the adolescence phase.
• This phase is considered as the phase of “stress and storm” as the child is unable to cope with physical growth and dual treatment of society, which neither consider them as a child nor as a grown-up.
• Most adolescents experience tension and instability as they are not prepared enough to meet the expectations of society as mature guys.
• The factors which affect them emotionally are- being bullied in schools, school demand, and pressure, sexual and social pressure, parental conflict, drug, and alcohol, etc.
• One-sided romance, glandular secretion, mood swing leads to heightened emotions and create conflict within. That makes them confused.
• Suffer from an identity crisis.

Conclusion: During adolescence, the child suffers from emotional ups and downs. An adolescent has to experience a number of emotional turmoil regarding identity crisis, sexuality, career choices, peer pressure, etc. So this phase is marked by conflict and confusion. Hence, Jealously towards brothers/ sisters in the family and peers in the school is not the characteristic feature of emotional development during adolescence.

The Correct answer is David Kolb

Experiential learning is learning by doing. David Kolb is best known for his work on experiential learning theory or ELT. 

Important Points

David A. Kolb’s Experiential Learning Theory:

The experiential learning theory works in four stages—

• Step 1:Concrete learning is when a learner gets a new experience, or interprets a past experience in a new way. 
• Step 2: Reflective observation comes next, where the learner reflects on their experience personally. They use the lens of their experience and understanding to reflect on what this experience means.
• Step 3: Abstract conceptualization happens as the learner forms new ideas or adjusts their thinking based on the experience and their reflection about it.
• Step 4; Active experimentation is where the learner applies the new ideas to the world around them, to see if there are any modifications to be made. This process can happen over a short period of time, or over a long span of time. 

​ 

Additional Information

• Kurt Lewin
  • He is known as the father of modern social psychology
  • Lewin's theory also contributed to the concurrent cognitive fieM psychology. 
  • Kurt Lewin’s field theory proposed that behavior is the result of the individual and the environment.
• Educational Thoughts of John Dewey
  • he a major educational reformer for the 20th century
  • John Dewey’s concept of education is based upon the philosophy of pragmatism.
  • Dewey believed that knowledge is resultant of action.
  • According to him, change is the reality of the world. 
• Benjamin Samuel Bloom's theory of mastery learning: 
  • It is an instructional strategy and educational philosophy, first formally proposed by Benjamin Bloom in 1968.
  • Mastery learning maintains that students must achieve a level of mastery (e.g., 90% on a knowledge test) in prerequisite knowledge before moving forward to learn subsequent information.
  • If a student does not achieve mastery on the test, they are given additional support in learning and reviewing the information and then tested again. 
  • This cycle continues until the learner accomplishes mastery, and they may then move on to the next stage

The term "curriculum" is derived from the Latin word "currere", which means "run". Thus curriculum means a course to be run for reaching a certain goal or "destination" here education is imagined as a race, with its aim as the goal and curriculum as the course leading to that goal. So the term' "curriculum" came to signify a group of subjects or courses of study, arranged in a particular sequence, for instructional purposes in school.

Important Points

Basis of curriculum construction

• Philosophical basis: Philosophy is important to all aspects of the curriculum. It provides educators, particularly curriculum workers, with a framework or base for organizing school and classroom activities. It helps them decide what school materials to use. Almost all elements of the curriculum are based on philosophy.
• Sociological basis: Education is a process of transmission of culture. Curriculum designers must consider the social settings in general and the relationships between school and society in particular. Curriculum planners also need to assess the influence these social factors have on curricular decisions. Curricular decisions take place in complex social settings through demands that are imposed by society and also have a direct bearing on schools. Hence, curriculum workers need to consider and use social foundations to plan and develop the capacity to respond intelligently to social problems. In this way, the curriculum serves both the needs of the learner and society.
• Cultural bases: Culture is an important factor in curriculum planning and drives the content of every curriculum. This is because the essence of education is to transmit the cultural heritage of society to the younger generation of the society. 
• Psychological basis: Psychology has provided various kinds of answers for the understanding of the teaching-learning process. As long as teaching and learning are important considerations for curriculum specialists, psychology will be important as well. Teaching and learning are interrelated and psychology cements the relationship; it provides the theories and principles that influence student, teacher behavior within the context of the curriculum.

Hence, we can conclude that Educational basis is not a basis of curriculum construction.

School-community collaboration occurs when groups or agencies come together to establish an educative community. 

Key Points

• As the community has to play a major role in the education system. SSA (Sarva Shiksha Abhiyan) also emphasizes community ownership of schools.
• When the relationship between the school and the wider community strengthens the ability of schools and families to support student learning, well-being, and developmental outcomes, it is called community collaboration
• Benefits of community collaboration:
  • Promote shared learning goals and collaboration. 
  • Increase learning opportunities for students. 
  • Create an inclusive learning community.
  • Encourage shared responsibility.

Hence, it is clear that option 4 is correct.

It has been proved by research that there is a positive connection between parents’ involvement and student success. Effectively engaging parents and families in the education of their children has the potential to be far more transformational than any other type of education reform.

• Teachers must involve parents in the education of their student's success in the schools.
• Parent involvement is considered to be one of the most important educational goals: Every school should promote partnerships with parents and families that will increase participation in promoting the social, emotional, and academic growth of children.

Key Points

​Building partnership with parents and families is essential to:

• improve opportunities and outcomes for students to raise parents' awareness of their ability.
• improve their children's learning and wellbeing and increase student achievement and success.
• form a positive parent-child relationship that is language-rich and, emotionally supportive.
• do better at school when their parent provides predictable boundaries for their lives, encourage productive use of time, and provide learning experiences as a regular part of family life.

Thus, it is concluded that building partnership with parents and families is essential to improve opportunities and outcomes for students to raise parents' awareness of their ability and consequently improve their children's learning and wellbeing.

Right to Education Act: Every child between the ages of 6 to 14 years has the right to free and compulsory education. This is stated as per the 86th Constitution Amendment Act via Article 21 A. The Right to Education Act seeks to give effect to this amendment.

Key Points

• Section 28, RTE Act 2009 states that “No teacher shall engage himself or herself in private tuition or private teaching activity”, banning all teachers. This Act is applicable only to government teachers.
• Private tuition is one of the ills affecting Indian education, which needs to be addressed.
• This provision will ensure that teachers do not use their position for commercial gain through private tuition, which is a source of harassment to children and parents. 

Thus, it is concluded that Under section 28 of the RTE Act, government school teachers are banned from private tuition.

Hint

• ​Section 22 provides for the preparation of a School Development Plan (SDP) by the School Management Committee. The SDP is visualized as a comprehensive plan focusing on all aspects of school e.g. protection of children’s rights, infrastructure, teacher availability, classroom transaction and child assessments, inclusiveness, etc.
• Section 20 provides power to Central Government to amend the schedule on norms and standards. 
• Section 25 seeks to provide for the maintenance of pupil-teacher ratio, by the appropriate government and local authority

The correct answer is- 'Don't we?'
Key Points

• It is a question of question tag and we know that the sentence and the question tag must be in the same tense.
• The given sentence is in the present indefinite so the question tag will also be in the present indefinite.
• If the sentence is positive, the question tag must be in the negative and vice versa. So that after following all the above rules we can say 'don't we?' will come here.
• Structure of Presente Indefinite:
  • Sub + V₁ + s/es + object (Positive)
  • Sub + Do/Does + not + V₁ + object (Negative)

​The correct sentence is- We often watch TV in the afternoon, don't we?

The correct answer is 'early'.

Key Points

• Grammatically, the filler needs to be an 'adverb.'
• In terms of usage, the correct collocation or usage of words in the given perspective is 'to get up early.'
  • For example, My grandfather always wakes up early in the morning.
• So, the correct filler to place in the blank is 'early' and the correct sentence: I get up early in the morning.

Hence, the correct answer is Option 2.

Additional Information

Concept used:

Mode = Value that occurs the maximum times in a data.

Range = Difference between the largest and smallest value in a data.

Solution:

(a)

(b)

If both groups are combined,

Freq(7) = 3

Freq(8) = 1

Freq(9) = 2

Freq(10) = 2

Freq(11) = 1

Freq(12) = 3

Mode = 7 and 12

Range = 12 - 7 = 5

Hence, the correct option is 1.

Solution:

The least square number which is exactly divisible by 3, 4, 5, 6 and 8 = L.C.M of 3, 4, 5, 6 and 8

L.C.M of 3, 4, 5, 6 and 8 = 2 × 2 × 2 × 3 × 5

L.C.M of 3, 4, 5, 6 and 8 = 120

Pairs of 2,3 and 5 are not completed. To make it a complete pair, multiply it by 2 × 3 × 5 = 30

Now, 120 × 30 = 3600.

The least square number which is exactly divisible by 3, 4, 5, 6, and 8 is 3600.

Shortcut TrickBy option elimination method, it can be easily seen that option (2) is a perfect square number which is also divisible by 3, 4, 5, 6, and 8
