In science class, after watching an educational programme on T.V., teacher have a lively discussion over the learning objectives. Which of the following principle is used here for effective use of teaching aids?

Teaching aids are tools that support and enhance the teaching-learning process by making abstract concepts more concrete and engaging. For these aids to be effective, certain pedagogical principles must be followed, such as preparation, selection, presentation, and follow-up.

Key Points

• When a teacher organizes a lively discussion after showing an educational program, the principle of follow-up and evaluation is applied.
• This principle emphasizes that teaching aids should not be used in isolation but followed by activities like questioning, discussion, or exercises that assess and reinforce student understanding.
• The discussion serves both as a reflective learning process and an informal evaluation, helping the teacher gauge whether the intended learning objectives were achieved.
• It ensures the teaching aid has served its purpose and allows students to process and articulate what they have learned.

Hint

• The principle of selection involves choosing the most suitable teaching aid based on content, context, and learner needs, but it does not relate to what happens after the aid is used.
• The principle of preparation refers to ensuring the teaching aid is ready and appropriate for the lesson, which happens before its use.
• The principle of proper presentation focuses on how the teaching aid is shown or introduced to the class, not what follows its use.

Hence, the correct answer is principle of follow-up and evaluation.
