Since the lectures focus mainly on specific details without explaining the overall structure or learning objectives, there were times when I lost track of the context—“What are we learning right now, and why?” You explain each individual tree in detail, but I feel that it is difficult to envision the shape of the entire forest.
At the beginning of the course, it would be much more helpful for orienting the learning process if you could first explain (1) where this course fits within the overall curriculum and (2) what learners will understand after completing it.
