My delivery method was within the context of a 25-minute lecture. This is typical of my teaching. In science, it is the case that there is often one correct answer. This is not subject to debate, unless you happen to be an expert in the field. I believe that I had a good lecture delivery, and as previously noted in class, I always welcome questions.
Lectures provide a format within which one can cover the most material in any single given hour.
Some classmates also thought that I should ask more questions during the lecture encouraging class participation. I always try to sequence the material so. There were also comments about there being too much material. Again, there is much material to cover in any single lecture, but I do try to break it up in a logical manner. I too must rely on the fact that the students have absorbed the previous material and can follow me forward to the new material.
