Some free, open, online, help forums are social networks that connect students with volunteer helpers who provide assistance with specific problems from coursework. The most popular existing mathematics help forum, Cramster, supports Cognitive Load Theory, and worked solution responses. Yet the solutions on Cramster are static text, and do not reflect established multimedia principles of learning. In this project, 40 video solutions answering high school math questions were placed on Cramster, and a methodology was developed for studying how students use such multimedia presentations in an authentic context. Some videos were the only solutions students received; others were presented alongside written solutions. Data included ratings and comments, viewing activity, and responses to questions on modality preference and helpfulness. Results indicate that it is feasible to deliver video solutions, and that students generally appreciated them, especially those that viewed them completely. Viewing activity logs can reveal how students use the videos.
