Class annotation of images

This is another post where I share how I did something, solely so I don’t forget how to do it.

Perusall is a wonderful program for annotating documents with a whole class, and I’m currently using it for all my online classes, which are located in the horror of an LMS they call Canvas. I upload a PDF, and students and I can highlight the document, with a panel popping up for discussion. When anyone clicks on the question mark, it indicates a request for responses. When anyone uses @Someone, it notifies them someone has responded. I have used it to solve the “what if they don’t do the reading?” problem, since we all kind of do the reading together.

All this is great. The system “auto-grades” (though I have to set it then check it very carefully), and pushes the grades to Canvas gradebook on my command, so I can focus on the discussion itself instead of evaluating it.

But you can’t do this with images — just upload and everyone talk about it.

Except…you can. Perusall won’t upload images natively, nor link to images directly on the web. So I downloaded an image, and saved it as a pdf in Preview, then uploaded it. Then I clicked on a section of the picture. Instead of highlighting text, Perusall put a pin. I can then ask a question or make a comment about just that portion of the image. Click the pin, and the conversation panel opens.

But the interface itself takes up a lot of the screen, which we don’t want for images. So I’m going to show students what to do about that:

If they do it, then it will look like this:

More room for the image, less clutter. I’m thinking it would be possible to put several images on a page to be discussed for that week.

What it’s doing is similar to ThingLink, which I learned about from our wonderful art historians over a decade ago. But ThingLink and similar programs, although they can be embedded into Canvas with iframes, cannot track a student’s comments, nor auto-grade them. Perusall can, which shortens my workflow so I can focus on the discussion, just as I do with annotated text.

So, annotations for images when I teach a European history course that focuses on the Humanities, and a History of Technology class that can get bogged down in text? I’m in!
