Audio is a powerful and impactful tool, but it is often used incorrectly within e-learning courses. recently had a discussion with Dan Bliton in his role at the Metro DC ASTD chapter about this topic, here is a small part of the interview. common question is "Should we have audio in the e-learning module that exactly matches the text on the screen?" The general answer is no. It’s not that you can’t learn from audio and text, it is just that the learning is more productive if the two are separate (audio that enhances what is on the screen not repeats it word-for-word). Here are some reasons why.
