I haven't read the paper myself and don't vouch for it, but I've heard two-sigma mentioned a lot.
- rahimnathwani 9y agoThe paper's here: http://web.mit.edu/5.95/readings/bloom-two-sigma.pdf http://web.mit.edu/5.95/readings/bloom-two-sigma.pdf It's not relevant to my specific question, as the three groups in the test had student:teacher ratios of (1) 30:1, (2) 30:1, (3) between 1:1 and 3:1 I'm interested in variation between the students within group 3, not the difference between the three groups.
