"If you want to master something, teach it. Or so the saying goes. But can students really learn better by explaining? The evidence says yes." • "Research shows that coming up with an explanation can help students learn more effectively than having an explanation handed to them (Fonesca and Chi, 2010). For example, when two groups of learners study the same material but only one group is tasked with explaining it (the other group engages in alternative tasks or spends an equivalent amount of time studying), the explainers typically outscore the non-explainers on a post-test (Lombrozo, 2013)."
