Feel free to play around with the following h5p interactive (one of the examples provided on the h5p site). I’m testing out if and how it tracks people’s engagement with the interactive. What does it do when someone who doesn’t have an account on this blog (and/or doesn’t login) interacts? What data can I see?
By default it appears that h5p/wordpress doesn’t really provide anything useful and a quick search didn’t reveal any possibilities.
This post provides a bit more detail on broader possibilites with xAPI and h5p, including this WordPress plugin (h5pxAPIkatchu). This plugin catches all the xAPI statements emitted by h5p interactives and stores them in the WordPress database for downloading for analysis.
