Information may prompt people to think, but illustrations prompt people to remember.
If you want people to remember, touch an emotional chord by painting a picture, relating an experience, or telling a story. There is a greater chance of the learning staying in long-term memory using these approaches than when only focusing on information.
If you have ever listened to a professional speaker or a good sermon, you will notice that the most often used pattern is to make a point and then tell a story. Sharing information without dressing it with some clothing just slips out of short-term memory. The brain thinks in pictures, not in words. Dress the information by painting a picture, and learning will be enhanced.
