ThingLink is a great FREE tool that can make images come alive with text, links, video, audio, and more.
I can see ThingLink being used in the classroom as a dynamic method of presenting information. It could also be a unique alternative to the traditional research paper, as research can be shared both visually and linguistically within a ThingLink graphic. To keep the focus on citation, simply have students create a Works Cited page in a Google Doc and put the link on their interactive image.
If you want more control, teacher accounts are available - view this blog post for details.
