For generations, educators have been recording live lectures and making them available for playback by their students.
Most of these 1st generation recordings are tedious to review. Speeding them up to double or triple speed doesn’t make them better…it just shortens the duration of the painful experience.
To be effective, electronic lectures should not be simply a taped rendition of a pre-existing lecture.
- There are too many pauses, throat clearings, accidental mis-statements
- The sound, recorded from the lectern, will generally be poor.
- The camera (video) usually never gets it exactly right on whether to focus on the speaker or the screen.
