Value for Teaching & Research
OF COURSE: record your lectures for your class
BUT: There are many other pedagogical uses:
Record presentation in one context and provide as supplementary info in another class or context
Record presentation in face-to-face class to possibly use online
Record your presentation at a conference to disseminate it more broadly via your CV, etc. (some conferences are now run this way)
