In an activity like this students may need to research information, synthesize it, define it, and explain the concept or topic in their own way. This requires them to really think about what is needed in a video about their topic that will help a viewer to understand the topic or concept fully.
This new tool is well explained and reviewed by Jennifer Gonzalez on the CULT OF PEDAGOGY website. If your interested she has a facebook account under the same name - very handy to see what she comes across. I have given the program a quick go and think it is one of the best of this style of video creation tools that I have seen in a while. I particularly like that it starts from a written perspective and then you add pictures to support that. In many previous tools students have focused on putting the fun good looking pictures on first but haven't thought about what it is they need to say first. This is a much better tool for this reason.
Below is an example of the style of the videos created.
