Step 1: Understanding the Concept:
Audio-visual teaching aids are tools used by an instructor to facilitate learning and improve retention.
These aids are designed to complement teaching, not replace the instructor.
Step 2: Detailed Explanation:
Let us evaluate both statements:
- Assertion (A):
"Audio-visual aids can only supplement the teacher but can never supplant him/her."
This is correct.
Audio-visual aids are tools that help the teacher explain complex concepts, make lessons more engaging, and improve retention.
However, they cannot replace the teacher's ability to answer unexpected questions, adapt the pace of the lesson, evaluate students, and provide human warmth and encouragement.
They are supplements, not substitutes.
- Reason (R):
"Since audio-visual aids play an important role in the process of Teaching-Learning, hence these may substitute and/or replace the Teacher in the Classroom."
This is incorrect.
No matter how advanced technology becomes, teaching aids can never replace the human elements of interaction, emotional intelligence, and customized guidance that a teacher provides.
Therefore, Assertion (A) is correct, but Reason (R) is incorrect.
Step 3: Final Answer:
The correct option is (B).
