Imagine that you want to conduct your undergraduate classroom in a more creative way and introduce practical projects as a part of the final grade. However, students are lazy to embrace extra activities, and all of them decide not to deliver any report.
The department does not like the trouble of failing all students in a course because of an extra project.
What would you do to implement change when students are widely resisting?

Additional Description: In fact, I want to change the grading system to reduce the weight of final exam, and add to small projects (e.e.g writing a one-page about the topic under consideration). The lazy class prefer to deal with one final exam instead of continuing homework. The school does not support this method, but they do not stop me as long as there is no trouble.
