I learned this technique for "video citizen journalism" from Richard Hering in a workshop he did for our English for Activists class in Tokyo. Seems like a great tool for activists that can also be a great tool for learners. The key factors are immediacy, a clear simple structure, and low technical barriers: you use the video camera on your phone, a simple formula for organizing content, and no editing or effects. (See remoscope for a similarly direct approach.)
The how-to leaflet assumes the video-maker is someone who wants to report on some kind of activism and share that information with the world via the internet.
The basic technique can be adapted for other goals and uses. In Nina Wallerstein's Language and Culture in Conflict, she describes how to produce codes that articulate problems in students' lives. Why not have students create their own? (Or, students can make short videos to evaluate the course, or for homework, or to bring issues from their lives to class for discussion, to interview people, etc.)
Here's the link to the how-to leaflet, and the link to their website:
