“…In considering how these three characteristics might theoretically influence the effectiveness of activities ( Nehm, 2019 ), we note that the presence, type, and timing of feedback are often dependent on the amount of constraint, as is the per-student instructor effort. That is, providing timely feedback is often only possible when an activity is highly constrained, or at least thoughtfully constrained at some intermediate level ( Meir, 2022 ). Activities where the interaction is highly constrained, such as through multiple choice questions, can easily provide immediate feedback to the learner, with a low level of per-student instructor effort.…”
