Participants will learn about the H5P interactive activity tool, how to find existing and develop their own free interactive H5P activities, how to embed H5P as formative assessments in Canvas LMS pages (or other LMS), and how to leverage H5P as summative assessments using LibreText's ADAPT homework systems. We will discuss which H5P are fully accessible and which can be made accessible with workarounds. Participants will leave the workshop with H5P as a valuable assessment tool in their educator toolkit. Participants will need to bring a computer and be connected to the internet.
