Concept:The demonstration method is a teaching technique where the teacher performs an experiment or procedure while students observe. Its main demerit is that students do not gain hands-on experience.
Explanation:In the demonstration method, the teacher does the experiment or activity in front of the class, explaining each step. Students only watch and listen, but they do not get to perform the task themselves. This limits their practical engagement and skill development. Among the given options:
- Option A correctly states this drawback.
- Option B (time-consuming) can be true sometimes but is not the primary demerit.
- Option C (economical) is actually a merit, not a demerit.
- Option D (learning by doing) is a merit of other methods, not a demerit of demonstration.
Hence, the most accurate demerit is that pupils do not get a chance to perform the experiment themselves.
Answer:Option A: Pupil do not get chance to perform experiment.
