This study investigates how well a video tutorial for software training that is based on Demonstration-Based Teaching supports user motivation and performance. In addition, it is studied whether reviews significantly contribute to these measures. The Control condition employs a tutorial with instructional features added to a dynamic task demonstration. The Review condition additionally includes video reviews. Participants were 55 seventh graders who viewed task demonstrations (and reviews) followed by practice. Both tutorials increased motivation (i.e., task relevance and self-efficacy) and performance. In addition, the Review condition had significantly better results for training time, self-efficacy and scores on an immediate post-test. Reviews have rarely been studied in dynamic visualizations. The present study suggests that there may be important advantages to be gained from concluding a demonstration video with a summary of the main points.
