Reading the report, and maybe because not being used to this kind of research, I was struck by the smallness of the measured effect sizes: 0.24, 0.38, those kind of values. See (http://languagelog.ldc.upenn.edu/nll/?p=1297 for the meaning of "effect sizes"). No evidence for disruptive effects here (but maybe this kind of research is not capable of finding real big changes, since this kind of research, by design, compares very similar situations) Actually, they were forced to consider mostly older learners, since “Few rigorous research studies of the effectiveness of online learning for K–12 students have been published.”
