Why does social learning work better than classroom instruction?
Betts explains why this works:
Learning from another person has … been shown to be vastly more effective than learning in a larger classroom group. Benjamin Bloom conducted his famous “2 sigma” study that showed that students learn much more effectively in a one-to-one environment than in the classroom. One-to-one tutoring in Bloom’s experiments was so effective that it transformed a “C” student into an “A” student—a movement of 2 standard deviations (or 2 sigma in statistical terms). This is a profound finding—we’re all capable of being “A” students when we learn from a tutor.
