The article discusses the importance of incorporating challenges into learning for better retention and understanding. Psychologist Robert Bjork introduced the concept of 'desirable difficulties,' illustrating that learning conditions perceived as challenging promote deeper mastery. Research supports that strategies such as spaced repetition, self-testing, and interleaving topics seem tough initially but significantly enhance cognitive encoding, leading to durable learning. Ultimately, the article argues that to achieve lasting knowledge, learners should embrace rather than shy away from difficult learning methods.
The harder we work at learning, the stronger our retention and understanding; desirable difficulties ultimately enhance our performance even when they initially seem unhelpful.
When mental effort in acquiring information is minimal, our brains tend to discard it quickly; the forgetting curve confirms that ease often leads to forgetfulness.
Bjork’s idea of 'desirable difficulties' fundamentally reshaped educational approaches, suggesting that challenges should be welcomed as they lead to mastery rather than avoided.
Effective learning strategies like spacing and interleaving, perceived as hard and uncomfortable, are actually key to achieving long-lasting retention and understanding.
