Demonstration based training (DBT) in the design of a video tutorial for software training
This study investigates the design and effectiveness of a video tutorial for software training. In accordance with demonstration based training, the tutorial consisted of a series of task demonstrations, with instructional features added to enhance learning. An experiment is reported in which a demonstration only control condition was compared with a demonstration with review condition. The review videos provided a recap to support retention of the procedure. Strict viewing conditions were imposed during training. Both learning and motivation were assessed. Participants were 55 students from primary and secondary schools in Germany. The outcomes showed that both tutorials significantly contributed to development of procedural knowledge and to motivation, and that the review tutorial surpassed the control. The discussion addresses the role of user control. In addition, with the effectiveness of reviews apparently becoming better established, the need arises for measures that can reveal the effects of reviews on observational learning processes.
