Ebbinghaus and the Forgetting Curve

Here's a link submitted by Jennifer, who states, 

"I thought this article was interesting regarding Herman Ebbinghaus' 'Forgetting Curve'. Since Ebbinghaus' forgetting curve means that learners will forget most of what they learned following instruction, I am always wondering about how to include follow-up coaching or 'refreshers' that students can access outside of the prescribed course module to help them with retention."
