Fоr mоst cоllege clаsses, exаms аre given at scheduled times during the semester.  What kind of a reinforcement schedule is this?  Let’s imagine I designed another course that is based on the number of tasks a student completes (at their own pace), instead of the amount of time.  For this class, students can take exam 1 once they have completed 3 assignments, they can take exam 2 once they have completed 3 assignments, and they can then take exam 3 once they have completed 3 assignments.  What kind of reinforcement schedule would this be?  For each class, describe the pattern of responding for these two schedules by discussing the similarities and differences between the graphs for these two schedules.   Finally, describe what the rate of responding would look like using what you know of feedback function.  According to feedback function, which type of exam schedule would encourage the student to work faster and thus possibly finishing the semester sooner?
