This article serves as a valuable resource for educators, administrators, policymakers, and anyone interested in the future of education and the promise of personalized and mastery learning.
Benjamin Bloom, an influential educational psychologist, conducted research in the 1980s comparing the effectiveness of different instructional methods. His most striking finding, published in 1984, was that students who received one-on-one tutoring performed two standard deviations (hence "two sigma") better than students who received conventional classroom instruction. This meant that the average tutored student outperformed 98% of the students in the conventional class.
The Two Sigma Problem, as Bloom framed it, was how to achieve these dramatic improvements in a more practical and scalable way than one-on-one tutoring, which is too expensive and resource-intensive for widespread implementation.
