...compares outcomes or gains from different learning conditions across two or more groups of students, who experience all learning conditions by alternating between them during a semester. At any point in time, students in different groups are experiencing different conditions. Each student serves as his/her own control, and sequencing of conditions is counterbalanced across groups. 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. This design reduces potential impacts from the sequencing of conditions or any lack of equivalence among course topics.
