The material in ED106 was presented very well. I have to say that I learned quite a lot from this course. It gave valuable guidelines for delivering clear presentation. I especially like the idea of prior to introducing a new concept, summarize what has already been covered, show a connection between what has been covered and what is to be covered, show applications, help the student to realize the relevance of it. Another great suggestion: the concept of using "pauses" effectively carries such an impact during the course of instruction. Bottom line: Great course, lots of valuable information.
