Older research that has shown a positive effect of smaller class size have observational rather than experimental; they have noted that school districts that have smaller classes have better performing students. Like so many things in education, this is technically true, but it fails to control for confounding variables, most importantly, IQ. In the States, districts that have smaller classes have been the wealthier ones that could afford to hire more teachers per student. But affluent districts have a higher-IQ population, and hence higher-IQ students. But when you change the class size in the same district but don't change the students, as has been done in minority districts in an attempt to boost their performance, you don't see much effect. |
