AB design

baseline data collected during the A phase, and intervention implemented in the B phase

ABAB (reversal) design

sequential application and withdrawal of intervention of following initial baseline. Baseline, intervention, baseline again, intervention again. temporarily removing the intervention in order to evaluate its effects on students' behavior

multiple baseline design

provides a way to evaluate the effectiveness of an intervention when a reversal (ABAB) design is not desirable because of the limitations noted previously - allows us to analyze the effects of intervention on three variables

changing criterion design

used to evaluate a slow and orderly increase or decrease in performance levels by changing the criterion for students to receive interventions in a stepwise fashion

changing conditions design

successive change in conditions for performance of behavior to evaluate comparative effects of intervention

alternating treatments design

allows us to determine the differential effectiveness of more than one intervention for a target behavior, different interventions are randomly alternated from session to session
