A new course format has been created for Open Learner to provide a more modern and and interactive look to a course. The Pop up activities course format displays resources and simple activities embedded in modals instead of redirecting from the course page.
If you are not using heavy server side assessment, but mostly resources and client side activities (SCORM, H5P), this format may help provide more interactive courses by opening the activities in popup modals instead of separate web pages. When students finish an activity or resource, they return to the course page by closing the modal without waiting for the course page to load again as it would normally do on a Moodle LMS.
There is a sample demo showing what it does available at https://openlearner.org/popups. The format itself is available at https://github.com/dthies/moodle-format_popups and can be install on any Moodle 3.10 site.
