We conducted a systematic replication of Cannella-Malone et al. by comparing the effects of video prompting to video modeling for teaching seven students with severe disabilities to do laundry and wash dishes. The video prompting and video modeling procedures were counterbalanced across tasks and participants and compared in an alternating treatments design within a multiple probe across participants design. For six participants, video prompting was more effective than video modeling, which was generally ineffective. For one participant, neither video modeling nor video prompting was effective, but in vivo instruction led to skill acquisition. One participant who was deaf was also able to learn both skills using video prompting, even though he could not hear the voice-over instructions. These data suggest that the duration of the video may influence its effectiveness as a teaching tool and that the voice-over instructions may not be necessary.
