In his initial study, “Visible Learning,” Hattie ranked 138 influences that are related to learning outcomes. In follow-up studies, he has now compiled 195 effects and rank ordered them. Any of the instructional strategies that have more than a 0.4 effect size are said to be high-impact. Here is a link to some of his research.
