What will video or slideshows change for instructors and learners? What instructors (often?) did in class after you assigned the reading for the next class like going over the main points of the reading and asking questions/giving quizzes/taking questions over the reading. The next step was to have people start applying it in class or introducing them to the homework before they left the class. The flipped version would have people read and view the slides, take the quiz, and know what they will be doing with the content in the next class. Comments to the EdTech article reminded people that thumb drives and DVDs could still provide out-of-class content used by student who might not have internet access outside of class. That said, I know one thing. This model supports use of class time for valuable learning support. And it takes time to create the materials, and space for faculty to upload materials, and that we shouldn't shy away from trying flipped approaches, that we can do so iteratively.
