Caryn Friedman, who is an expert in reading literacy. When we chatted about the flipped class she feels that the place for the video is not at the beginning of learning cycle but rather in the middle. She tells me that if a student watches a video and learns something incorrectly, then she will have to help the student un-learn the content before they re-learn it correctly. She sees the flipped videos as being better suited (for her purposes) as remediation and practice. So make sure you think through where the video (or if a video) is best suited for a particular lesson.
