I believe the answer is extended examples.
I have two reasons for saying that.
1. I’ve learned from experience, extended examples are highly effective in many ways.
2. I think I have answered this question for someone else or on one of my own exams. Your choices are most likely:
•peer testimony
• statistics
•visual aids
•brief examples
•or the correct answer, extended examples.
I hope I have been successful in assisting you. Please let me know if you have further questions!
