Activities are interactive items of content that you can add to a course. Unlike resources (which tend to be passive content items) activities encourage participation from learners and other courses users - whether that be making a post, submitting an assignment, casting a vote, or other interaction. There are a wide range of different activity types available in Totara Learn, from interactive SCORM e-learning modules through to glossaries, forums, seminars, quizzes and more.
