text: Firstly, a teacher has a certain credibility that students do not. The goal of these assignments is to help the students fortify their knowledge over summer so that it is not lost. These teachers go through years of university studying the subject that they teach, so why should a student who has taken the class for one year have authority over summer assignments. For example, AP BC Calculus is an immense subject with a variety of different units of math. If a student tried to make a summer study guide, they would only have a year of experience under their belt. On the other hand, teachers, who have been teaching/studying this subject for years, have a strong understanding of each unit and how to teach it in a unique way. The credibility of the creator of the assignment must be strong, so the student can have an easier time understanding the subject. Thus, teachers should be assigning summer assignments.
