KVS TGT Science Mock Test - 3 - Question 10
The formation of personal identity and integration with society gives rise to conflicts. This statement is related to _________ development challenge in adolescence.
Detailed Solution for KVS TGT Science Mock Test - 3 - Question 10

Adolescence is a phase of life of a person when he is no more a child and not yet an adult. It is a period of transition between childhood and adulthood that involves a number of changes in body and mind.

Key PointsThe adolescent is no longer a child. He is a new person emerging into an adult. This process of understanding the self and seeking meaning and direction leads to identity formation. Challenges related to Psychosexual Development:

  • Conflicts result from the development of a person's identity and social integration.
  • Adolescents often find it difficult to control their emotional reactivity and instability, which can lead to behaviours that are at times inappropriately extreme, such as excitement, anger, sadness, depression, and embarrassment.
  • The development of personal identity is difficult for adolescents from underprivileged and minority groups.
  • They entered into serious relationships, experienced heartbreak, and felt stress as a result of exploring their own sexuality and sexual identity.

Thus, we conclude that the formation of personal identity and integration with society gives rise to conflicts. This statement is related to Psychosocial development challenge in adolescence.

KVS TGT Science Mock Test - 3 - Question 11

Which of the following pairings is correct with reference to community?

I.Community as a pressure group - To supervise the functioning of the school teachers, principals etc.

II. Community as a resource - Parents can give children practical knowledge and skills.

Detailed Solution for KVS TGT Science Mock Test - 3 - Question 11

A community is a group of two or more people who have been able to accept and transcend their differences regardless of the diversity of their backgrounds (social, spiritual, educational, ethnic, economic, political, etc.). This enables them to communicate effectively and openly and to work together toward goals identified as being for their common good.

Key PointsCommunity as a pressure group:

  • Pressure groups are organised associations, unions or organisation of people having common interest. Their aim is to seek better conditions for their members through organised efforts.
  • School is a sort of mini-community. Community as a pressure group supervise the functioning of the school teachers, principals etc.
  • Teachers are likely to work in a manner in which they receive stimulation through interaction with the community and the various ways in which people cope up with the problems of the school and carry on its activities in a constructive manner. 

Community as a resource:

  • Community resources provide first-hand experiences to the child and s/he is able to develop proper concepts about various aspects of processes of community life.
  • Since parents of school children are part and parcel of the community, they can pay informal visits to the school. They can provide practical knowledge and skills and participate in school administration.
  • Thus, education is supported by the community and becomes less expensive. Moreover, gap between education and community is bridged, making learning informal and interesting.

Hence, it is clear that both I and II pairings are correct with reference to community.

KVS TGT Science Mock Test - 3 - Question 12
According to the 'element of fatigue' principle of timetable construction, subjects like arts, crafts, writing, science practicals, and manual work, etc., should be pursued in the __________.
Detailed Solution for KVS TGT Science Mock Test - 3 - Question 12

Preparing a good timetable is really a complicated piece of work because a number of factors and conditions that change from school to school i determine it. Its construction, therefore, requires thorough concentration and perseverance of mind. While constructing a good timetable, important principles should always be kept in view.

Key PointsPrinciples of Timetable Construction: The element of fatigue:

  • Fatigue, in reality, is the state of inability to continue work after a prolonged activity of certain parts of the body. Fatigue weakens attention and perception and diminishes the power of insight and initiation. Hence the work rate is also diminished.
  • In school, some subjects are more fatiguing than others. They involve heavy mental strain and effort. Such subjects should be taught during the early hours when the brain is fresh.
  • It has been noted psychologically that the second and third periods on a school day are the best when the work curve reaches its highest point. Similarly, the second and the third days of the week are the best when momentum is the highest.
  • Monday is only the warming up day and Saturday is perhaps the worst. So subjects like English, regional languages, and Mathematics should be taught during the best periods of the day.
  • Similarly, subjects like arts, crafts, writing, science practicals and manual work, etc., that require less energy should be pursued in the last periods.
  • Lastly, the duration of periods must change according to age, physical condition, and season. In summer, periods should be of shorter duration as compared to winter.
  • Similarly, in the case of primary classes, periods should not be very long. Small children get fatigued very soon and, so they need frequent changes in activities and occupations.  

Hence, it is clear that according to the 'element of fatigue' principle of timetable construction, subjects like arts, crafts, writing, science practicals, and manual work, etc., should be pursued in the last period.

KVS TGT Science Mock Test - 3 - Question 13
Achievement data is collected with a focus on the science content that is most important for the students to learn. Which of the following facts leads to a contrary opinion?
Detailed Solution for KVS TGT Science Mock Test - 3 - Question 13

As science has increasingly pervaded our lives, it has become more than a sum of physics, chemistry, biology, and mathematics. Using science in daily life improves life chances. Let's understand more about the nature of science below.

Key Points

  • Science is a dynamic expanding body of knowledge covering ever-new domains of experience.
  • It is an organized system of knowledge that is based on inquiry born out of natural curiosity, logical reasoning, and experimentation. Every student can understand the scientific content by employing the correct methods of teaching. 
  • The nature of science: is an objective way of looking at things that is not biased and based on empirical data.
  • There are several methods of conducting research in science namely action research, experimental research, survey method and etc.
  • Science relies on the fact, not on beliefs or opinion that is not dogmatic. It does not unreasonably insist on standing by preconceived notions, concepts, or ideas that have been proved wrong through careful experimentation. 
  • Science is a self-correcting enterprise, i.e. it is open to change. Many hypotheses proposed by scientists turn out to be wrong.  
  • Science progresses by disproving which means the scientific theories can be falsified. They can be challenged with facts and evidence that any scientific theory can be proved wrong. 

Therefore, by understanding the very nature of science, it can be said that it is not correct that only intelligent children could understand science.
