Desktop capture refers to video (and usually audio) capture of computer screens. The audio is commonly in the form of a voice-over from a microphone. So it is commonly used to capture speech over PowerPoint slides - much like in a lecture.
Ideas for use:
- Providing short lecture materials and using lecture time for discussion and answering student questions - checkout the HotQuestion activity in Moodle for a good way to focus on the most pressing questions among a large cohort of students.
