text: If teachers were the ones designing the summer projects than they could put a little bit of everything from the previous years curriculum. Students who already know one subject extremely well wouldn't be able to just do the entire summer project on that an forget the rest of it. Students would retain the information much better if the projects weren't focused on just one subject but all of them. They would recall the material as they worke on small portions of the units in the projects. Coming the next the students would be better prepared to continue learning new material.
