Kirkwood has recently adopted Pressbooks. This includes the ability to author H5P exercises, which can be used to enhance Pressbooks OER (Open Educational Resources) or can be embedded for a variety of stand-alone online activities. The H5P PB Kitchen site is a grant-funded project for the BCCampus (https://bccampus.ca/), which has been a leader in OER in Canada. Anyone who wants to learn about the use of H5P in Pressbooks could learn a lot by starting here. Alan Levine ran the project, whose grant has recently ended. The site still includes many good resources for learning more about H5P as a way to develop interactive OER.
Below is a link to resources from a workshop H5P conducted by Levine and is a good introduction to H5P.
