We've spent some time recently with the creative team behind ThingLink.
ThingLink is a free, very easy-to-use tool that enables you to tag an image and add up to 1,500 characters of text about the image, and include a link, in the tag. The link can be to any file on the web, including text, video or audio.
Below is an example in which a human skeleton is tagged with Wikipedia entries describing the major parts of the skeleton.
ThingLink will be quite useful for student project in which the student creates and tags a timeline of photos, with a few links on each one.
We write often of the imperative to teach students "ways to communicate their ideas in a manner that engages modern audiences." ThingLink is one such way.
I am eager to see the ingenious ways in which students learn to use this tool.
