If I were to make some changes to this course I would include different types of exercises to encourage learners to practice their skill. I would get students to talk more by providing oral exercises and questions. Although these exercises cannot be corrected, it would at least increase the amount of interaction that is present in the course.
The structure of the course was always the same. This was good as navigation was easy, but there could have been a little deviation to include a longer grassroots video, or an exercise that perhaps involved reading and responding to a text.
