Playposit was originally Educanon. I have worked with this site for a long time and have also had the pleasure of speaking with the owners a few times to suggest improvements and give ideas for its use. Needless to say if I have put the time in to talking with these people I find the product VERY useful and worthwhile. It is a free site that lets you take video off the net and layer interactivity into the video. For example say at the 1 minute mark there was an important statement made and you want your students to remember. In Playposit you can automatically stop the video and add a question or a statement or a variety of other interactive options. It makes the flipped classroom concept a no-brainer. This is definitely worth a look… and it includes my favorite word… its free to use!
