The power of the iPhone is its portability and connectivity. The way I imagine this working to support teacher education is prospective teachers are in a classroom to do observations in order to understand inquiry science pedagogy. The teacher is doing a lab with students working in groups. Prospective teachers with an iphone would be asked to follow different student groups and collect videotape of how those students were engaged in the activity. When class is over, all students can then transfer their video to the instructors' laptop. Then the class can analyze the lesson looking not just at the teacher or one group, but at any group in the class. You could, for example, ask prospective teachers to make hypothesis about student learning based on the video of one group and then "test" those hypotheses with video of other groups.

Here is what I want: I want a tool that would be the equivalent of track changes / comments type of feedback features, but for a video and audio platform. I want to be able to watch video, tag a section, and attach a comment there in text, graphic, audio or video file type. We (here at PSU, including Carla Zembal-Saul who thought this up first) have been talking about this since we first started using the iPod as a voice recorder for video analysis. We wanted to be able to listen to an audio file and insert audio comments directly into the original file which would allow a sort of branching at that point. A student listening to the file could skip to the comments (the way you would with chapters) and listen to what I have to say about their work. The next stage in this, that I would find considerably more valuable is a system where I can code a section of video (a la Studiocode) draw students attention to a particular part of the screen (a la Diver) and then add these annotation to the original video like the director's comments are added to a DVD. A student collects video of themselves, marks up their own video (the way I just described) as part of a reflection on their own practice then gives me the video. I can watch just the marked sections, or the whole thing. I can mark up the original with text, audio comments, or even attach small sections of video of another teacher (student or otherwise) as an exemplar. All this gets stored as different tracks that allow commentary to be turned on and off. The video becomes a dynamic tool for reflection and dialogue between faculty and students as well as student/student and student teacher / mentor teacher. Imagine being able to watch a section of video with a student's comment on their own teaching, their faculty instructors and their mentor teacher all in one file. That is a pretty killer app from my point of view.
