Bloom Two-Sigma Effect
Summary
Students who were tutored one-on-one showed a prodigious improvement in their performance and mastery of the given subjects, compared to the control group in Bloom’s experiment. This has a couple of interesting consequences —
- If we can use technology to provide similar individualized attention (maybe through AI) without expending the human resources otherwise necessary, we might be able to make a pretty big change in education.
- Labeling students as weak or strong ignores a whole range of factors that could significantly change their educational performance.
Bloom found that the average student tutored one-to-one using mastery learning 202006241451 techniques performed two standard deviations better than students who learn via conventional instructional methods — that is, “the average tutored student was above 98% of the students in the control class”.
Seems like there are two parts to this — the fact that instruction was individual, and the mastery learning pedagogical techniques involved. Not sure why those weren’t separated? Or maybe mastery learning techniques involve one-on-one teaching as a subset.
