A single-shot training given at the pre-service level to the teachers, as has been the common practice so far, will no longer be sufficient for them to survive professionally unless they choose to regularly update and upgrade their skills, competencies, and awareness.

• For achieving these objectives of professional development in-service teachers as well as teacher educators, various agencies and institutions such as SIERTs/SCERTs, BSEs, and national institutions like NCTE, NCERT, IGNOU, and NUEP) have undertaken the responsibility of the particular sectors of teacher education for the cause of Universal Elementary and Secondary Education.

Key Points

• Special orientations of a large number of mainly primary/elementary level school teachers were organized under a programme called Programme of Mass Orientation of School Teachers (PMOST).
• This program was launched by NCERT which is an organization that looks after various programs meant for imparting quality education at the national level. NCERT interacts with International Organizations for organizing certain programs and training.
• An estimated number of 5,00,000 teachers (50 teachers in one camp) participated in 10,000 teacher's orientation camps conducted in 2,500 training centers for 10 days (09.00 hours to 17.00 hours on all days).
• SIETs/CIET prepared total 41 modules of 11 to 30 minutes. The programmes for telecast were originally produced in the Hindi language. In the case of non-Hindi regions, the programmes in English were preceded by a synopsis in local languages.
• The objective of PMOST was to create a conducive climate for generating initiative in teachers for implementation of the present education policy at the school level. 

Hence, it is clear that NCERT launched the training programme, 'Programme of Mass Orientation of School Teachers (PMOST)'.

Mental illness is a broad term which includes almost all the disorders of behaviour which are caused by faulty perception, emotion, thinking and attitude. Such individuals have problems in making adjustments with others in the society

Key PointsCharacteristics of mental illness are - 

• Lack of concentration
• Poor coordination and movements
• Random behaviours
• Lack of attention 
• Memory loss
• Behavioural issues and problems
• Extreme weight gain or loss
• Difficulty in understanding and remembering etc.

Hence, the problem with swallowing of food is not a characteristic of mental illness.

The Right to Education (RTE) Act of 2009 in India mandates that all children between the ages of 6 and 14 years have the right to free and compulsory education.

Key Points

• The assessment of learning as per the RTE Act involves regular evaluations of students to monitor their progress and ensure that they are meeting the necessary learning outcomes.
• The Act specifies that the assessment should be continuous and comprehensive, and should not lead to the failure, detention, or expulsion of students.
• Instead, the focus should be on providing additional support to students who are struggling, so that they can reach their full potential.
• The assessment of learning should take into account the diverse needs of all students, including those with disabilities and disadvantaged backgrounds.
• Section 30 provides that no child shall be required to pass Board examinations till completion of elementary education. 

Therefore, it can be concluded that as per the RTE Act 2009  assessment of learning is about No child shall be required to pass any Board examination till completion of elementary education.

From prehistoric time experts has been trying to understand and explain leadership, however, differences in opinion and isolated ideas failed to demonstrated a comprehensive process of leadership that make an ordinary person leader or an ordinary leader an effective leader.

Key Points

The comprehensive leadership model tries to portray a complete leadership that integrates all the isolated opinions of experts that can be generalized in a different perspective.

Leadership is a comprehensive process which understood as the ability some people have to guide or command other people's actions. It is more than just that, though. A comprehensive leader is a dominating individual and supporting group of people.

• Leader knows himself quite well, both his weaknesses and strong points.
• Leader summons for personality, not by fear.
• Leader is supported by strong background knowledge.
• Leader makes use of strong common sense.
• Leader exchanges some ideas among the group and also direct them about their goals and help them to achieve them.
• Leader has a personal relationship with any and all of his followers.
• Leader knows how to make use of his people's strengths and weaknesses to achieve the goals they had in mind.
• Leader serves others in the achievement of the objectives, and not the other way round.

Information and Communication Technology (ICT) is defined as a diverse set of technological tools and resources used to communicate, create, disseminate, store, and manage information.

Key Points

Disadvantages of ICT:

• Not accessible everywhere- The majority of people may not be able to afford the handsets, mobile time, or data packages required to utilize mobile internet, even if they live in an area with service. And even when people can afford technology and connections, it can not be accessible due to language barriers, a lack of digital literacy, or other issues. 
• Impact on children- Social media have good and bad information. Children may tempt to open bad information. It may open up doors for the exploitation and abuse of children through the usage of ICTs. Since parental supervision and monitoring are limited, children can readily interact with strangers and exchange enormous data files.
• Risk of privacy- Information technology may have accelerated, sped up, and enhanced communication, but it has also raised privacy issues. Individuals are becoming more anxious that e-mail hacking and mobile phone signal surveillance could cause their formerly private information to become public knowledge. Aside from these problems, a few other hazards that could affect our daily lives include computer worms, trojan horses, malware, spam, and phishing.

Hence, we conclude that all the options are the backdrop of ICT except that "it is not very useful to children with special needs as technology is not very developed".

Hint

• Information and communication technologies (ICT), when made accessible and available, enable children with special needs to fully and effectively engage, on an equal basis, in all facets of society and development.

The Latin meaning of the term ‘curriculum’ is a ‘racecourse’ used by chariots. Hence, it can be understood as any path or course of study which to be undertaken by an educational institution, to be covered in a specified timeframe.

Key Points

• Tanner and Tanner said, “Curriculum is the reconstruction of knowledge and experience systematically developed under the auspices of the school (or university), to enable the learner to increase his other control of knowledge and experience” 
• Carter V. Good describes the curriculum as “a systematic group of courses or sequences of subjects required for graduation or certification in a major field of study.
• According to Wiles and Bondi, “a curriculum can be called a plan for learning, which contains assumptions about the purpose of education in our society, it also has a definite structure through which the vision of the planners can be translated into learning experiences for the learner.
• According to Brown D.F. curriculum include all student school experiences relating to the improvement of skills and strategies in thinking critically and creatively, solving problems, working collaboratively with others, communicating well, writing more effectively, reading more analytically, and conducting research to solve problems. 

Hence, it is concluded that the above statement is given by Tanner and Tanner.

We know, the gravitational force  
 

This is valid when R is the centre to centre distance between the two masses M and m.

At a distance r < R, the mass of Earth cannot be taken as M.

The new mass (M'):

The mass of earth will be contained for a radius r. Let us assume that the mean density of the earth is ρ and that earth is a sphere with a radius equal to the distance r. We know, mass = density × volume

Therefore the gravitational force, 

Hence the gravitational force, F ∝ r

Fringe width is inversely proportional to the distance between slits so it will be doubled.

NOTE : Magnetic lines of force form closed loops.
Inside a magnet, these are directed from south to north pole.

Path difference = (l1 + l3) – (l2 + l4)
for destructive interference
Path difference = (2n + 1) λ/2
from (1) and (2)
(l1 + l3) – (l2 + l4) = (2n + 1) λ/2

We know that the continuity theorem says that if the cross sectional area of the water flow decreases, the speed must increase to maintain the volume of water flown. And according to Bernoulli's principle if the speed of water flow increases , then the pressure must decrease.

(b) Distance between the hostel and the station = 10 km = Displacement of the car

∴ Average velocity = 

The needle will point along W-E if the result of the earth’s magnetic field and magnetic field due to the coil have a resultant in the W-E direction. This happens if B cos 45^o=Earth's field
⟹ (μ0​nI​/2r) cos45^o=(4π×10−7×30×0.35​)/(2×0.12) ×(1/√2)​​=0.39G=Earth's magnetic field.

When rubber ball completely filled with water its centre of gravity will be at its centre, as water will fall through hole its COG will shift towards lower side leading to increase in length of pendulum and thus T, when very small amount of water will be left in rubber ball its COG will again shifts upward causing decrease in length and thus T, and finally when rubber ball becomes empty its COG will be at its centre and T will remains same as earlier.

Length of the wire, l =15 m
Area of cross-section of the wire, a = 6.0 × 10⁻⁷ m²
Resistance of the material of the wire, R = 5.0 Ω
Resistivity of the material of the wire = ρ
Resistance is related with the resistivity as,
ρ=RA/l
=5.0×6×10⁻⁷/15
=0.2×10⁻⁶Ωm

e = NBAω = NBA²πn = 8 x 0.5 x 0.09 x 2 x 3.14 x 60 = 136V

Horizontal component is a component of Earth’s magnetic field along the horizontal direction in the magnetic meridian. It is denoted by B_H. If B is the intensity of Earth’s total magnetic field, then the horizontal component of Earth’s magnetic field is given by:
B_H=Bcosδ

The rate of loss of heat by a body is directly proportional to its excess temperature over that of the surroundings provided that this excess is small.

The nature of light which is verified by the interference event is wave nature. Even though light has dual nature interference experiments only tell us about the wave nature.

f​₁=7.5×10⁶ Hz
f₂​=12×10⁶ Hz
λ_1​=c/f₁​=40 m
λ₂​=c/f₂​=25 m
 
So, the range is 40m to 25m

Dimension of work and energy are the same i.e. [ML²T⁻²].
 Power = Energy/Time,
 Energy = Power × Time (in terms of hour instead of second),
 Energy = Watt × Hour,
= [ML²T⁻³] [T],
= [ML²T⁻²].
But, Momentum(p) = Mass × Velocity,
 p = [M] [LT⁻¹],
 p = [MLT⁻¹].
Hence the Dimension of work, energy and watt-hour is the same i.e. [ML²T⁻²] but the dimension of momentum is different ([MLT⁻¹]).

This is a direct result from NCERT. In Young's double slit experiment, the distance of the nth dark fringe from the centre is
