A few assignments can be missed without lowering grades. To implement this method, I rely on small-group structure as I'll explain more fully in a moment. The group structure offers additional advantages. The small groups can he used for discussion, generation of questions and so on all of which help get students connected to the class in a profound way. Attendance is much better than when groups are not used.
Students are more involved and committed to the class.
Peer grading and use of cooperative groups asks students to act as responsible adults, and most respond this way. Additionally, students feel more relaxed, more free to raise questions and comments. This process creates a positive ambiance in the whole class. Since using this method, my classes have more humor, are more relaxed, and at other times more deep and serious than before. It took me years to let go of traditional grading methods.
