The growth and development of human beings are influenced by a variety of factors categorized broadly as internal and external.

Key Points

Internal Factors: All those factors which lie within the individual are called internal factors. These factors include heredity, biological or constitutional factors, intelligence, emotional factors, and social nature.

• Biological and constitutional factors: These factors include genetic factors and hormonal factors. All these parts are essential for one's development into an adult human being. A child’s constitutional or physical make-up, somatic structure, physique, and body chemistry influence his/her growth and development throughout his/her life.
• Heredity factors: the heredity factors play their part at the time of conception in the mother’s womb. What is transferred to the offspring from its immediate parents in the form of genes and chromosomes at this time constitutes the hereditary contribution. This contribution is the real starting point and basis for all the growth and development that take place later in the life of the child.
• Intelligence: Intelligence- the ability to learn, adjust and take the right decision at right time- has a significant role in the overall growth and development of the child. It affects his/her social behaviour, moral judgment and emotional growth.
• Emotional factors: Emotional factors, e.g. emotional adjustability and maturity, play a big role in influencing a person’s overall growth and development. If a person cannot exercise reasonable control over his/her emotions, he/she is sure to suffer in terms of his/her growth and development.
• Social nature: A person’s socialization helps him/her in achieving adjustment and advancement in other aspects of his growth and development. He/she may learn from his/her environment, more by means of his/her social nature, which may prove to be a boon to him/her for his/her proper growth and development.

Hence, all are internal factor(s) on the growth and development of children.

• Leadership differs greatly in personal style and these differences really matter. Consider the behavior of two different types of teachers.
• In one class a teacher truly "ran the show". He/she took firm control of all the class activities and left no doubt about who was in charge.
• He/she made all decisions and never asked for students' input. He/she even posted a long list of rules in front of the room, telling learners to do or not to do in a wide range of situations.
• Another teacher offered a sharp contrast to this approach. He/she seemed to enjoy sharing his/her authority with students and let the class vote on many decisions. And while he/she too had rules, they were much more flexible and were never posted in a formal list.

Traits of good Leadership in the classroom:

Key Points

Personal Qualities of a Leader

• Being Honest & Consistent: Honest and consistent in behaviour; more concerned with the good of the organization than personal ambition
• Acting with Integrity: Open to criticism and disagreement, consults and involves others in decision-making; regards values as integral to the organization
• Being Decisive, Risk-taking: Decisive when required; prepared to take difficult decisions, and risks when appropriate
• Inspiring Others: Charismatic, exceptional communicator; inspires others to join them
• Resolving Complex Problems: Capacity to deal with a wide range of complex issues; creative in problem-solving

Additional Information

Leithwood identified three fundamental goals pursued by transformational leaders in school:

Helping staff develop and maintain a collaborative, professional school culture

• Collaborative goal setting
• Delegating power
• Promoting school's norms and beliefs
• Strengthening productive school culture

Fostering teacher development

• Developing a shared vision for the school
• Partnership in school improvement goals and priorities

Helping teachers to solve problems more effectively

• Holding high-performance expectations
• Providing individualised support
• Supplying intellectual stimulation

Information and communication technology (ICT) refers to the use of electronic technology to send save, create, display, share or exchange information. Radio, television, video, DVD, satellite systems, computers, etc. are included in the ICT technologies.

• The tools of ICT are not a single technology but a combination of hardware, software, multimedia, and delivery systems. It may be in the form of audio, visual, and audio-visual. 

Key Point

Advantages of ICT Tools:

• Cost efficient - ICT tools are cost efficient as sending an email is cheaper than phone calls. ICT has also helped to automate business practices, thus restructuring businesses to make them exceptionally cost-effective. ICT tools make availability of free e-contents.
• ICT as Auido-Visual aid - A teacher can use ICT tools as teaching aids to stimulate the interest of students in learning. For example, a teacher who is going to introduce adjectives to class Ist students. He can use graphics, visual presentation, and audio-visual aids to make classroom learning interesting.
• Direct classroom learning: ICT tools are used in direct classroom learning as these tools shift the learning from solitary learning to learning with others. It makes learning more active in nature as there is direct interaction of the learner with ICT tools. It places the learner at the center and encourages collaborative learning in the classroom.

Hint

• Reliance on technology: Errors can be caused by over-reliance on and trust in technology’s proper function. Technology can occasionally malfunction, misdirect users, or give incorrect information or recommendations that result in users changing a previously correct decision or following a pathway that leads to error. Over-reliance on technology can result in serious consequences.

Hence, it is clear that reliance on technology is not an advantage of ICT tools.

Socialization is the process by which children are transformed by their parents, teachers, and others into social and cultural animals.

• We learn the language of the culture we are born into as well as the roles we are to play in life.
• Socialization is a process of acquiring values, beliefs, and expectations.

Important Points

• Socialization is a process of internalizing the norms, culture, values and customs of the society to be socially acceptable.
• Secondary socialization is a type of socialization which refers to the growing child who learns very important lesson in social conduct from his peers.
• Peer groups are the agents of 'Secondary Socialization' which takes place throughout one's life.
• It helps children to learn appropriate social attitudes such as how to like and enjoy social life and group activities.

Note: Refer to the table to be familiar with types of socialization:

Hence, secondary socialisation refers to the growing child who learns very important lesson in social conduct from his peers.

Language development refers to acquiring the ability to comprehend and produce language. 

Key Points The agencies that contribute to language development -

• Family- It is the primary agency that facilitates language development. The child gets to listen to the sounds, words, and meaningful sentences in a family environment.
• School - It plays a role in the holistic development of a child but by the time a child reaches school, he has already acquired his first language. It might play a role in the development of a second language.
• Mass-Media - It is not a primary agency of language development.
• Magazines - It helps in the development of the reading and comprehension skills of a child.

Hence we conclude that Family is the primary agency of language development.

Additional Information Language Development takes place in the following stages -

• Cooing - It refers to producing vowel sounds. It is the infant’s oral expression that explores the production of vowel sounds.
• Babbling- It comprises consonant as well as vowel sounds; to most people’s ears.
• One-word utterances-  these utterances are limited in both the vowels and the consonants they utilize.
• Two-word utterances - children start combining single words to produce two-word utterances.
• Complete sentences - After 2-word utterances, the child starts joining the words and making the sentences.

Tests may be of different forms, such as psychological test used to measure mental and behavioral traits, achievement test to assess performances of students, etc. They can be used to assess both the scholastic and co-scholastic abilities of the students.

Key Points

• The anecdotal records provide a means for the observation of one’s behavior
• The anecdotal records are used to record specific observations of individual student behaviours, skills and attitudes as they relate to the outcomes in the program of studies.
• Anecdotal records should be factual report of an event in a child’s life reported with adequate details so that it is a meaningful evidence of his/her behavior.
• A good Anecdotal record has the following features:
  • It provides an accurate description of any event.
  • It describes a setting sufficiently to give the events meaning.
  • If it includes interpretations or evaluation by the recorder, this interpretation is separated from the description and its different status is clearly identified.
  • The event relates to the child’s personal development or social interactions. 

Hence, we can conclude that the anecdotal records are used to record specific observations of individual student behaviours, skills and attitudes as they relate to the outcomes in the program of studies.

Additional Information

Inclusive education is an approach, seeks to address the learning needs of all children, youth, and adults with a specific focus on those who are vulnerable to marginalization and exclusion.

• It implies all learners, young people - with or without disabilities being able to learn together through access to common pre-school provisions, schools, and community educational settings with an appropriate network of support services.

Key Points

• An inclusive classroom promotes learning of all children, with special abilities, with various social backgrounds, and with diverse learning needs.
• In the inclusive classroom, each student gets access to knowledge, skills, and information, which improve available choices to all children and we do not necessarily limit ourselves to the knowledge domain, but rather include the affective domain, and the attitudinal domain as well.
• Every child gets the opportunity for quality and optimal learning and for enjoying learning together and actively participating in learning activities. The activities are more-cooperative and collaborative so that each child can participate effectively.
• In an inclusive classroom, there will be less stress on competition, grades, and covering the course as the child will be given importance so that they can learn effectively.

Thus, it is concluded that more effort by teachers to "cover" courses is least important in an inclusive classroom.

Explanation:

Speed of the man, v_m = 4 km/h
Width of the river = 1 km

Correct Answer :- d

Explanation : a) A topological sort of a directed acyclic graph (DAG) is any ordering m1, m2, …, mn of the nodes

of the graph, such that if mimj is an edge then mi appears before mj . Any topological sort of a

the dependency graph gives a valid evaluation order for the semantic rules. 

b) The parse tree can be annotated with synthesized or inherited attributes. The parse tree can also be indicated with an arrow mark to indicate the manner in which the value gets propagated between the nodes of the parse tree. This graph is called as dependency graph as it indicates the dependency between nodes for deriving the values. This graph is an acyclic graph which doesn’t have a cycle. The presence of a cycle indicates that the graph is incorrect as the dependence of nodes for deriving values cannot be predicted. Edges in the dependence graph show the evaluation order for attribute values and thus the graph is a directed one.

L =0.14
E=100sin(100t)
⇒X_L​=w_L​=100×0.1
=10Ω
⇒i_o​=E_o/XL​=100/10​=10A
⇒i=i_o​sin(100t− π/2​)
⇒i=−i_o​sin[(π/2)​−100]
So we get
⇒i=−10cos(100t)A
therefore, option D is correct.

Velocity of ball at top = V1 = VT + VCOM

Velocity of ball at bottom = V₂ = | VT – VCOM |

V₁ >> V₂ than other option.

∴ More pressure difference is created because

 constant

The plate which connected to high voltage generator induces negative charge on ball which causes attraction. When the ball strikes the positive plate, charge distribution again takes place that is the bass becomes positive and repulsion takes place. When it strikes the plate which connected to earth than its charge goes to earth and again it will be attracted towards positive plate. Hence the ball swings backward and forward hitting each plate in turn.

• Displacement quantifies both direction and distance of an imaginary motion along a straight line from the initial position to the final position of the point.
• Here, since the same amount of distance is covered in the opposite direction, the total displacement for the entire trip is zero. 

A tuning fork is made of an alloy of steel, nickel and chromium, called elinvar, i.e. the material for which the elasticity does not change.

Electromagnetic waves vary in wavelength and frequency. Longer wavelength electromagnetic waves have lower frequencies, and shorter wavelength waves have higher frequencies. Higher frequency waves have more energy.

• Eddy currents are the currents induced in solid masses when the magnetic flux threading through them changes.
• Eddy currents also oppose the change in magnetic flux, so their direction is given by Lenz’s law.

Water is used as a coolant in automobiles radiators because it has high specific heat capacity. So, it absorbs a large amount of heat for a degree rise in temperature.

When a tangent is drawn at any point on field line then that tangent gives the direction of electric field at that point
