HOW TO CREATE A ONE-MINUTE LECTURE Professors spend a lot of time crafting hourlong lectures. The prospect of boiling them down to 60 seconds — or even five minutes — may seem daunting. David Penrose, a course designer for SunGard Higher Education who developed San Juan College's microlectures, suggests that it can be done in five steps: 1. List the key concepts you are trying to convey in the 60-minute lecture. That series of phrases will form the core of your microlecture. 2. Write a 15 to 30-second introduction and conclusion. They will provide context for your key concepts. 3. Record these three elements using a microphone and Web camera. (The college information-technology department can provide advice and facilities.) If you want to produce an audio-only lecture, no Webcam is necessary. The finished product should be 60 seconds to three minutes long. 4. Design an assignment to follow the lecture that will direct students to readings or activities that allow them to explore the key concepts. Combined with a written assignment, that should allow students to learn the material. 5. Upload the video and assignment to your course-management software.   http://chronicle.com Section: Information Technology Volume 55, Issue 26, Page A13
