Sorry this took so long... I'm just figuring out how these classes work! I'm a face-to-face person as you might have guessed from the materials.
I agree, your comment is the BEST approach. However, there are people who go to 'the dark side', who substitute slick presentation skills and tricks for good solid knowledge. It is critical that all these techniques be mapped to the learning objectives of the class to ensure that its education rather than edutainment.
