If you haven’t read my last column advocating social learning in large lecture courses, I recommend reading that first — that’s where I explain why I think this technique could be so successful in a lecture-based classroom. This article is for the nitty-gritty, actionable advice for both students and professors to incorporate social learning into their experiences.
1. Study groups are more than an excuse to hang out with your friends — they’re an excellent way to incorporate social learning into your study routine. Quiz each other, force full explanations by eliminating vague words, and don’t be afraid to ask lots of questions. Social learning works best when you’re with a group you’re comfortable with. To prevent non-productive chit-chat, place your study group in an environment more conducive to studying, such as a reservable library room or a study lounge space.
2. If allowed, work with friends on problem sets. I cannot emphasize enough how important it is to actually do the problem first – don’t just rely on a friend who’s already done the work to explain it to you. Mull over a tricky problem, try your best, and explain your reasoning to a friend; often, in the act of explaining you’ll find where you went wrong. You can adapt this strategy for reading-based courses too — try finding time once a week to meet up with a classmate and talk over difficult parts of the reading, or explain a sequence of events.
3. Frame things as a story and anthropomorphize the characters. Give those cellular processes motivation and give the movement of atoms a plot. Humanizing inanimate objects may feel silly, but in the long run you’ll find that they become easier to remember. This technique works best when ‘telling’ the story out loud to a group of friends also in the course.
4. Is your professor receptive to new ideas or open to suggestions in office hours? Try talking to them about the ease and benefits of incorporating social learning into their courses! Change often comes from within, and I choose to believe that most professors care about the quality of their teaching. If they seem receptive and want more information, the experience of Eric Mazur (a physics professor at Harvard who pioneered large lecture social learning techniques) might be a good place to start — try here for a casual article and here for a peer-reviewed report.
1. You’ve read this far and clearly have an interest in improving the quality of your teaching, and that’s great! If going ‘all in’ and flipping the classroom seems like a lot of work, start small. Try breaking your lectures up into more meaningful chunks. Three to four usually work best. Separate those segments with productive socialization by asking your students open-ended questions, or telling them to discuss what you just explained. Giving students a break to talk to their neighbors might seem counterintuitive, but research shows that you’ll increase engagement and information retention this way.
2. Switch it up – one surefire way to lose a classroom is by throwing a lot of information uniformly at your students. I get that there’s often a lot to cover, but if none of it is retained, or worse, your students give up ten minutes in, a high throughput approach won’t work. Try emphasizing that all of the material won’t be covered in lectures, and instead focus on the difficult concepts. Trust that your students can learn the easier stuff on their own.
3. For Tip #2 to work, you have to have a pretty good sense of what’s actually difficult for your students. As a professor, what you think is difficult and what your students are confused by may be two very different things. Often times, students will feign knowledge of a previous topic to avoid embarrassment if the class has already moved on. The best way to get past this is to foster an open environment where it’s encouraged to discuss what problems they’re having with the material. Take the pulse of your course frequently, and take advantage of your TAs. Not only do they interact with students more frequently and more informally, they’re closer in both age and experience level to your students and likely will have a better sense of where the material is difficult.
4. Use exams better. Too often, students will cram information a day or two before the exam, knowing that they’ll never need to access it ever again. Try to reward long-term learning by giving students an opportunity to get some credit for revising exams and spend time going over concepts where many students were incorrect. Administer low-stress and high-frequency mini-quizzes to both get an easy straw poll of where the class is and to lower overall test anxiety. Strive to ensure that all quizzes and exams are testing content and not process. While students are familiar with memorizing steps to solving a problem, many of them will not comprehend the underlying logic that you’re ultimately trying to test. Check out Eric Mazur’s physics concept inventory for an idea of what this sort of exam might look like.
5. Feeling good about the changes to your class so far? Think about diving into a full flipped classroom model for your next round of teaching. It’s more work up front than a traditional lecture, but the resulting increase in student engagement and exam scores should speak for itself. Review and edit the structure and organization of your lectures for digital format, and then pre-record shorter lecture-like segments explaining each topic to be assigned before in-class time. Make attending class required, but also make in-class time useful. Provide spaces for your students to work in structured small groups on practical assignments, and use both yourself and your TAs as roaming sources of assistance.
This is only a short list of some easily-implementable ramifications of social learning – there are dozens more which I don’t have the room for in this column. To summarize all of the above into one comment it is this: socialization is a natural impulse and should be taken advantage of in the classroom accordingly.
