But nothing can happen if we ont act now.                                                            Many schools have considered requiring students to complete projects over the summer break. If required, should these projects be teacher-designed or student-designed? In my opinion, teacher-designed projects seems like the best interest for students. When students design these projects, they would probably make them very simple and boring, just to get out of work. Projects created by students will probably not be appropriate at school. Also, student-designed projects will not be taken serious by the students. However, individuals may have different opinions on this topic.
