Randomization Method
Each semester, one professor will teach one section whereas the other professor will teach two sections. The section of the professor who teaches only one section will be the Group Quiz section. One of the sections of the professor who teaches two sections will be randomly assigned to be the Individual Quiz section and the other will be the Group Quiz section. The randomization will be done with a coin flip.
In the Group Quiz sections, students are randomly assigned to their partners by a computer and this is repeated after every 4 quizzes.
