text: Teachers have all the information about the courses they teach and what their students need to know each year. Teacher-designed projects would entail the necessary topics and lessons for students to work on during their summer break. Other people might argue that the students are also well informed about what they are being taught so should create their own summer projects but most students might just have an idea about what they need to know but might not know about the course in detail as much as the teacher does with all their years of experience and trying new approaches to figure out what works best for their students. Students might also just want to create projects that would be very easy to complete just so they can get it over with. At the end of the day if students are allowed to create their own projects they end up learning nothing new because it was based on stuff they already knew. For example a Geometry teacher teaching tenth graders would not create a math project for tenth grade students based on sixth grade math because that is way below them.
