I’ve just learned that a few of my responses to questions on this forum were never actually posted and I’m sorry that this was one of them! Hopefully this isn’t too late:
The Hypothesis plugin for WordPress should work similar to the way the PressBooks plugin works (as far as I understand it on the PressBooks end). I do know that with the WordPress plugin you can set the annotation pane to automatically appear for students, and that they can read other public annotations, even if they’re not logged in. However, they will need to log in to create their own annotations. You can also create private groups in Hypothesis, which can be used in conjunction with the WordPress plugin, but students would also need Hypothesis accounts to see private group annotations.
It would be wonderful if we were able to have a more seamless integration with CBOX OpenLab, but unfortunately this is not currently possible due to some technical issues with the way that Hypothesis works. While it’s not likely to happen in the short or medium term, the CBOX team has been in communication with the developers of Hypothesis and we’ll be among the first to know when this request becomes possible on their end. So, we’re supportive of such an integration and it’s on our radar!
In the meantime, I’d suggest trying out the WordPress plugin, and perhaps creating or pointing students to some documentation about how they can create Hypothesis accounts, and how they can use it to read and create annotations on a WordPress site.
Again, sorry this post slipped through the cracks!
