ThingLink allows the user to add interactive elements to an image. In my example below, I've provided simple textual analysis of elements of the painting, but users can also add audio, video, web links, or other images. For teachers, this tool can provide an interactive way for teachers to lead students to instructional content. What I made is something that a student analyzing images (paintings, advertisements, photographs) as part of a history, English, or art class could create to show his or her understanding of visual composition and purpose.
Blendspace probably has more uses for teachers than students. It provides templates for content and easily allows users to search and insert content from Youtube, Google, Flickr, and others, link to a webpage, upload a file or image, or create a quiz. I created a Blendspace on MLA formatting where I embedded two Youtube Videos, uploaded two documents I usually give to my students, and linked to a website. All of the information is now in one place for students, and the quiz at the end assesses whether or not they have looked at the content provided. Now, instead of spending 15 minutes of class time explaining this to students, they can look at it in their own time and as many times as they need to. In my classroom, I would probably link this Blendspace to a QR code at the top of every paper assignment I give out.
