Adult students performed better in an intensive course (110 hrs in 5 weeks) than in an extensive course (110 hrs in 7 months) in language education programs.
🤔 But, there’s also evidence that learning a complex skill like a new language slowly and steadily improves our memory due to repeated exposure to materials over time (Spacing Effect).
💡 One consensus is that people learning a new skill like a language will benefit from first intensively studying until they are conversational, then transitioning to continuous/period review instead of just studying 30 minutes per day from the start. I personally prefer to learn this way.
I wonder about the impact of intensive versus extensive learning experiences. Do students in UX design bootcamps forget more than their college counterparts who spread design classes over four years? Is a 21-day racial equity challenge worse for anti-racist thinking than training taken over a year?
How do you prefer to learn?
