Description and Examples of Educational Mini-Clips
As stated earlier, an EMC is a 3-10 minute video of an instructor solving a specific problem. Typically, the clip is similar to watching someone solve and explain a problem on a whiteboard, however, in EMCs you only see the board, not the person. The video controls (e.g., pause, rewind, fast forward) allow the user to determine the pace of learning. EMCs are stored in a shockwave format to reduce size and download time. Ideally, EMCs should be stored in a well-organized database so that users can easily search and find what they need.
Perhaps the best way to understand what EMCs are is to view them (see Appendix A). The examples in Appendix A are based on mathematics, primarily because, currently, this is the leading topic covered by EMCs. However, clips could be created for a variety of subjects and purposes. For example, most science-related subjects, with clearly defined problems, are suitable subject matter for EMCs. In addition, administrative EMCs explaining course outlines, format, design, and assignments can work quite well. In fact, as stated earlier, it appears that a majority of questions for distance learning are based on administrative and procedural problems (Harper et al., 2004).
