No more than 6 words to a slide? This may bring a culture shock to many - I guess that's the difference between actually presenting material, and just giving them a handout of information!
I like the acronym SUCCESs, though it's amazing how obvious these key principles are, yet we have made strides to steer away from using them! I'm really enjoying the aspects of unexpectedness, emotions, and stories - it only makes sense that when students become emotionally attached to the material, they will retain more.
