Some of the popular perceptions about social science are that social science is the encyclopedia of the events and facts. The past events provide unnecessary details which are of no use. It transmits textbook information which only needs to be memorized. It did not help in promoting the development of the higher order cognitive skills as it promotes rote memorization.

As we all know that critical thinking is the ability to think clearly and rationally about what to do or what not to do. So, critical thinking is required in all the fields for an individual whether it is academic performance, workplace and daily life. An individual need to think clearly and rationally in every field and our each and every day to day life needs.

Secondary sources are second-hand sources of information as they are based on analysis and interpretation of primary sources of information. Secondary sources can provide a variety of expert insight and they are more efficient in terms of time consumed in researching information.

Dignity of labour and Home management responsibilities both are relevant to discuss gender parity. The cultural values of a particular area are described as a major constraint on efforts for gender equality, and therefore action is considered to be difficult for practical reasons.

Secondary sources are based on the analysis, evaluation and interpretation of primary sources on the topic of study. Secondary sources provide a broader context on the current state of knowledge on a topic.

Diagnostic test finds out the weakness or deficiency of a child in learning of content. It is an effective tool for teachers that help in planning and organizing remedial teaching. This test is used to detect the following types of errors committed by the student during mathematical operations as addition, subtraction, multiplication and division.

In mathematics utilization of available conditions and resources to the fullest extent either to attain maximum or minimum value in a given condition is known as optimization.

Statement I is the correct example of optimization of mathematics because here men use the available resources to save their time and money.

Statement II is not the correct example of optimization of mathematics because here there is no use of available conditions or resources. Here only one's observation is shown.

Mathematics is the basis of all sciences. It is related to human life. Mathematics generates logical aptitude. It gives training to different faculties of mind. It provides a definite way of thinking. The children who study mathematics develop their attitude with which they learn to work systematically, regularly and properly. Mathematics helps in character formation as well as morality. It develops the characteristics of discipline.

The supervised study may be individual or collective. The teacher provides proper guidance and direction to students in solving the problems or performing the work assigned to them, therefore supervised study is very helpful to such students.

Group works help students to clear the given topic in a wider way, as he can see a lot of responses for the same topic. It also boosts confidence and helps students to speak fluently in the public. It helps in clearing the topic in a small period of time.

Conjectures do not have utility in constructing mathematical knowledge is a wrong statement. As we know conjecture is a statement in mathematics in which falsity and truth are not known. If a learner knows about it and tries to find out the proof or disproof then this is going to help them to explore, and exploration leads to experience. It comes under the constructive approach of learning.

Mathematical communication involves the precise use of language so that students can understand both problems and solutions better.

Conjectures refer to statements that are likely to be true based on available evidence, but they are not formally proven.

Hypothesis refers to an assumption taken to be true. It helps in proving formulae and theorems in mathematics.

Mathematics statements are said to be true if certain arguments are proved to be valid, hence the notion of argumentation is central to mathematics.
