This document compares traditional in-person classes to online classes. In a traditional class, students meet at a scheduled time and place each week to participate in live lectures, discussions, and activities. Tests and assignments are completed and submitted in class. By contrast, online classes are more flexible as students can access course materials on their own schedule through the week. Discussions, assignments, and tests are completed independently and submitted online rather than in live class sessions. Both formats involve elements of passive and active learning through various activities assigned by the professor.
