...compares outcomes or gains from different learning conditions within a single group of students, who experience all learning conditions by alternating among them during a semester. At any point in time, all students experience the same condition. Each student serves as his/her own “control”. This design enables comparisons of teaching strategies (e.g., “condition A” vs. “condition B”) by an instructor in a single course section, even with small enrollment. However, one must account for the potential impact of the order in which conditions are experienced and whether conditions are confounded with course topics, which may not be equivalent in difficulty or other factors related to learning.
