Videos and PowerPoint

There are hundreds of instructional videos at YouTube, and some are excellent. Those about installing or repairing programs and devices tend to be exceedingly helpful. However, videotaping of a formal class lecture is seldom very successful.

Why not? Pacing is a major problem as with any lecture because the material comes too rapidly for some viewers and too slowly for others. Furthermore, passive viewing is inferior to interaction with the material.

This or a similar program has become the standard for seminars. The speaker guides the audience through the material, and imagine how lame the presentation would be without him or her. The teacher adds:

  • Pacing to suit the attention of the audience
  • Emphasis through intonation or loudness
  • Asides and digression
  • Additional explanation as needed
  • Interaction as with responses to questions
