Have you ever tried thinglink? It’s a way of making images interactive. I can see many possible uses for the classroom and presentations.
Using Thinglink I turned my PKM graphic into an interactive image you can “touch.” When you are looking at the image you will see small circles next to each of the icons. When you hover over the circle, a description for each part of my PKM will appear. When you click on it, it will take you to a specific example.
