41. According to the constructivist approach to learning, knowledge is:

Transmitted directly from teacher to student without modification Actively constructed by the learner through experience and interaction Fixed and unchangeable once taught Gained only through reading textbooks

Explanation: Constructivism holds that learners actively build their own understanding through experiences, reflection, and interaction with their environment.

42. The primary aim of teaching Science as a school subject is to develop:

Rote memorization of definitions Scientific temper, curiosity, and inquiry skills Skills for competitive exams only Ability to copy diagrams from textbooks

Explanation: Science education aims to foster scientific temper, curiosity, and the ability to observe, question, and reason logically.

Explanation: Remedial teaching targets specific gaps or misconceptions identified through diagnostic assessment of individual learners.

47. Which teaching approach emphasizes learning science through hands-on experiments and self-discovery by students?

Lecture method Heuristic/Discovery method Rote learning method Dictation method

Explanation: The Heuristic (Discovery) method encourages students to learn concepts by conducting their own investigations and experiments.

48. A good science curriculum/textbook should primarily aim to:

Encourage rote memorization of definitions Connect scientific concepts with everyday life and encourage inquiry Focus only on theoretical content without activities Avoid practical work due to time constraints

Explanation: An effective science curriculum links concepts to students' daily experiences and fosters inquiry-based, activity-oriented learning.

49. Misconceptions held by students in science should ideally be addressed by:

Ignoring them since they will resolve on their own Punishing students for giving wrong answers Using diagnostic teaching and conceptual clarification Avoiding any discussion of the topic in class

Explanation: Misconceptions should be identified through diagnostic techniques and corrected through targeted conceptual clarification.
