I wanted to briefly address this point. I raised the same issue in the other thread under messages of support for Matthew. I completely agree with the argument that is made above. In my educational experience, as classes progressively became more intricate and detailed in terms of content and complexity, the demand also rises to spend more time outside of class studying the content of lecture notes, handouts, and textbooks at greater length to increase comprehension of what you're supposed to be learning. Once I began to record lectures, it provided me with another resource, in addition to the others, that not only enhanced my education, but it resulted in more A's. The ability to go back and review parts of lectures that are complex gave me the opportunity to better understand what I was learning.
Don't take it just from me, folks. Professor Claude W. Olney, J.D, who teaches at Arizona State, also encouraged students to consider tape recording lectures.
Oh by the way, Prof. Olney, for those who don't know who he is, was the author of the benchmark series "Where There's A Will, There's An A: How to Get Better Grades In High School."
