Office Mix (http://mix.office.com) is a free add-in for PowerPoint 2013 and higher that allows you to make your presentations more interactive. With Mix you can record and narrate slides, add screen recordings and screenshots, insert video and audio, and add interactive quiz questions. Mixes can be uploaded to the Office Mix website where they can be stored, shared, embedded into websites (like Blackboard!), and/or published, or you can export your mixes as a video. If you choose to upload your Mix to the website, you can track the number of views, times spent on slides, answers to quizzes, etc.and easily export this data to Excel and Blackboard. Best of all, Office Mix is easy to use thanks to an ever growing gallery of how-to videos.
