I learned that there is a lot more to online course delivery than I realized (although I was not teaching online recently). However, what struck a chord with me was that whether online or in person, retention levels are correlated to the amount of effort from the student. I see that a lot with my students; those that put in the effort will learn the concept. Also, the other concept was that if students are actively engaged in the learning process, their learning outcome is higher. Again, some students would rather sit back and not take part in lessons...leading to them struggling with the lesson or concept being taught.
