Research suggests that audience attention in lectures starts to wane every 10-20 minutes. Incorporating active learning techniques once or twice during a 50-minute class (twice to or thrice for a 75-minute class) will encourage student engagement. Active learning also:

This handout graphically represents the relative complexity of different active learning techniques. It also provides brief descriptions for each of the activities on the continuum.
