Lectures play a vital role in teaching. There will always be a place for lectures in the curriculum -- to give technical material or factual information, to provide structure to material or an argument, to display a method or example of how one thinks in a given field, or even to inspire and motivate students to explore further. At the same time, it often enhances both your presentation of the material and students’ learning when students are able to participate in some way. When students engage actively with material, they generally understand it better and remember it longer.
