I am always on the lookout for new free tools for creating content for Flipped learning, and Zaption seems to fit the bill quite nicely! You can add video clips that you have created, or that you have found online, and make a tour out of this sequence. To this, at any point in the tour or individual clip you can add a multiple choice question, open response or check-box response. You can also add text slides, image slides and even drawings to your tour. This allows you to create an entire online lesson segment, and share the link to this. The service is web-based, requiring no download, and is free, although pro features can be purchased.
The interface is easy to use. To add a multiple choice quiz to your tour, you drag the progress cursor to the required position in the video and drag your chosen option type (eg. multiple choice) into the sidebar next to the video and type in the question and options. When you click submit, it is added to the tour. By adding slides at appropriate points you can add notes or details to your video in a very useful manner. You can unpublish and edit your tou at any time, publishing it again when you have finished updating. Neat!
It is a pity that you cannot download the file to place on other platforms, but you can share via a link which can be placed on your Moodle or Edmodo page quite easily. All in all Zaption will be a welcome addition to a range of new web-based tools for creating interactive video content quite painlessly for your flipped content.
