Ever since I can remember, I have been told that “lectures” are the worst way to for students to learn. I saw a great presentation recently that highlighted the learning pyramid and talked about lectures at the top of that pyramid. For this and many other reasons, lectures have gotten a bad reputation.
The trick is what is meant by “lecture.”
Essentially, when you look at the pyramid, you see that audio-visuals, demonstrations, and discussions are among the techniques that enhance learning. However, I would argue that great presentations incorporate all of these techniques, and in the right settings, can even get to practice and having students teach other. I think that “lectures” in this setting represent the extreme of purely regurgitating (likely in a monotonous tone) information from a text to the learners. To further emphasize this point, Issa, et. al. has published two papers in the past 2 years showing both short term and long term learning and retention benefits using educational design principles in the presentation.
So, the way I look at it is like this: Presentations can have a range of effectiveness and it is up to us to break the “curse” of the pyramid and make great presentations that optimize learning and retention.
