text: When students don't care about what your teaching and have no motivation to learn the topic, students will just not pay attention and recall nothing that you have taught. Being able to recall information and understand it well is very important, but most students can't just recall information that they don't care about at all. Allowing a student to choose a topic for one project for summer could be the way to getting to know a student, or to just allow them to learn information that they didn't even know they enjoy. Recalling information is part of the human brain, but the less you like and enjoy the information the less your gonna remember what you learned. Teachers will not always provide the greatest projects so letting students choose will allow them to learn and even recall what they learned because they actually care about the topic.
