Robert Bjork says that you can teach alot of things, quickly, but students will not learn deeply or with long-term retention. In order for a student to carry what they learn into their life, throughout life, they must learn fewer lessons, learn those lessons multiple times, and in multiple ways. Students may not enjoy this, as it doesn’t feel as much like they are progressing, yet nonetheless, they are truly learning something which will change their life in this manner.

“Desirable difficulties” which assist in slowing down learning for the sake of depth and retention include:

-interleaving

-variability

-spacing

-tests

-reducing feedback
