Many schools across the country require students to complete summer assignments to assure that they continue their pursuit of knowledge even without a teacher present. But should these assignments be designed by the teacher or should they be designed by the student? If a student were given freedom with their project, it would be a lot more enjoyable rather than if a teacher put strict conditions on it. But a lack of strictness would mean that students are less likely to complete their project and they wouldn't know when the work they have done is enough. Teachers should put that restriction on the student and give them a specific assignment to ensure that the appropriate amount of work gets done.
