CMS: Course Management System is online educational/learning/teaching platform. The course structure includes modules and lessons. To be effective, teacher has to know more than their course content. They must know the goals of e-learning, course delivery strategies and techniques, and how to deliver instruction/content online. As a teacher I must understand that my students will get (easily) frustrated. Which is something I encounter often in my Google Classroom and Canvas. The is the need for both learning and technical support as these often alleviate many student frustrations. Another issue I often encounter is there will be a few who simply refuse (as they do synchronous) to do the assignments.
