STRY is a multimedia timeline creation tool that I've been a fan of since it launched a couple of years ago. One of the features that makes it different from other timeline tools is that you can build quiz questions into your timeline. HSTRY also offers a collaboration option for students and teachers to use to create timelines together. In the video embedded below I provide an overview of how to create a multimedia timeline on HSTRY.
Applications for Education
There are two features of HSTRY that make it stand-out from the crowd. First, as a teacher you can create an online classroom in which you can view all of your students' timelines. Second, as a teacher you can build questions into timelines that you share with your students. You can even build-in explanations of the answers to your questions.
