Step 1: Identifying the best approach.
When a student is struggling to understand a concept, it is important to offer constructive support. The best approach is to provide additional learning opportunities, such as attending a remedial class, where the student can receive individual attention and clarification on the topic.
Step 2: Evaluating other options.
- (A) Making the student to stand on the bench: This is a punitive measure and does not address the student's learning needs.
- (B) Asking the student to write the concept 20 times: While repetition can sometimes help, it is not a productive or engaging way to address a student's understanding of a concept.
- (D) By giving corporal punishment: This is an inappropriate and harmful approach that should never be used in educational settings.
Step 3: Conclusion.
The best approach to helping a student who is struggling with a concept is to provide them with additional support through remedial classes.
Final Answer: Asking the student to attend the remedial class.
