"John Hattie developed a way of synthesizing various influences in different meta-analyses according to their effect size (Cohen’s d). In his (original) ground-breaking study “Visible Learning” he ranked 138 influences that are related to learning outcomes from very positive effects to very negative effects. Hattie found that the average effect size of all the interventions he studied was 0.40. Therefore he decided to judge the success of influences relative to this ‘hinge point’, in order to find an answer to the question “What works best in education?” " This year, Hattie expanded his research to include 256 influences that relate to achievement.

In this session, we are going to look how how instructional design and technology can play a major role in affecting achievement.
