I’m a proponent of using OER in an LMS, preferably an open source one, which leads me to promoting both Moodle and MoodleNet.
Moodle is free and opensource. MoodleNet is free and opensource. The more people that use them the greater the support network. An institutional instance is not necessary; an instance for one class is economical and doesn’t require anybody from IT to be involved. MoodleNet will handle most kinds of file formats. I think you could upload a D2L course file if you wanted to (I haven’t tested that.) Moodle courses can be constructed so that all activities and functions work in Canvas, D2L, and Schoology. I have tested all of those. That means that any of the 27 math courses that are Moodle files that I’ve uploaded to MoodleNet will work in any of the other LMSs as well.

I think we need to expand our thinking as to what a ‘book’ is. Higher Ed is still enamored with the notion that a book is something that must be capable of being printed on paper and that when printed it should look the way that books have been printed for the last 5 centuries or so.
I think a book that is used in classrooms of any kind needs to have activities for students to do that foster learning. The book should have a way for students to talk to each other and the teacher built in. The book should have a way for the teacher to present all manner of assessments to students in many different ways. I’m not a big fan of analytics but some people think it’s important. Interfacing with AI is also something that a book might beneficially do.
Here’s the presentation I did for OpenEd22 which is focused on elementary and secondary (K12) and those classrooms that don’t have reliable or any access to the internet.
