text: It's the teachers' job to teach students so that they can be successful in whatever they chose to study in college or universities. It's their job to ensure that the student has learned the standard learning criteria and maybe even more. Teacher-designed assignments are made to make sure that the students have some idea of what the course will be like, so that on the first day of class, students can engage themselves in the discussion. For example, if a student decides to take a new course that they have never taken before, they must have some background knowledge when coming to class on the first day. A summer assignment will help them figure out what they should already know coming into the first day. Students are not aware about all they information they need to know, and if they design the project themselves, they could miss majority of the information, so it's important that the teacher designs the project, even if it's a lot of work, it will be beneficial for the student in the long run.
