Wired recently published an article on active learning. (here) Some excerpts:
"Think back to when you learned how to ride a bike. You probably didn’t master this skill by listening to a series of riveting lectures on bike riding. Instead, you tried it out for yourself, made mistakes, fell down a few times, picked yourself back up, and tried again. When mastering an activity, there’s no substitute for the interaction and feedback that comes from practice."
"A new study in the Proceedings of the National Academy of Sciences addressed this question by conducting the largest and most comprehensive review of the effect of active learning on STEM (Science, Technology, Engineering and Mathematics) education. Their answer is a resounding yes. According to Scott Freeman, one of the authors of the new study, 'The impact of these data should be like the Surgeon General’s report on “Smoking and Health” in 1964–they should put to rest any debate about whether active learning is more effective than lecturing.'”
"1. Students in a traditional lecture course are 1.5 times more likely to fail, compared to students in courses with active learning." "The authors point out that, were this a medical study, an effect size this large and statistically significant would warrant stopping the study and administering the treatment to everyone in the study."
"2. Students in active learning classes outperform those in traditional lectures on identical exams" "On average, students taught with active learning outperformed those taught by lectures by 6 percentage points on their exam. That’s the difference between bumping a B- to a B or a B to a B+."
Conclusion: "“[Under active learning,] students learn more, which means we’re doing our job better. They get higher grades and fail less, meaning that they are more likely to stay in STEM majors, which should help solve a major national problem. Finally, there is a strong ethical component. There is a growing body of evidence showing that active learning differentially benefits students of color and/or students from disadvantaged backgrounds and/or women in male-dominated fields. It’s not a stretch to claim that lecturing actively discriminates against underrepresented students.”
At this point I usually add some comments. However, this article says it all.
