How I Use It
I posted a video and asked students to comment on three aspects of the video and to respond to each other's posts. The students enjoyed being able to playback the video to track evidence. They also seemed to have commented on similar points of the video. I had a bit of trouble locating a post that was not blocked by our school filters. TeacherTube, Vimeo or Wingclips are good sites to use if YouTube is blocked at your school. You can also post videos you have created.
It's important to discuss videos WHILE they're playing. In addition to immediate recall of important ideas, it would give all students an instant (or delayed if watched later) dialog about important concepts. An additional, and valuable feature, is also the fact that teachers can post questions to direct students' thinking toward crucial points of interest - and students can answer questions with the ability to comment on, not just what they're viewing, but on the content of what their peers have viewed. Students can edit comments, and the teacher can delete comments or evaluate a post before it is allowed to be posted.
