Visible Learning is a meta-study published by the education researcher John Hattie in 2008 that analyzes the effect sizes of measurable influences on student learning outcomes, synthesizing results from 815 other meta-analyses. Using Cohen's d as its common measure, the study ranks instructional strategies and interventions by how strongly they correlate with student achievement, finding for example that self-reported grades (d=1.44), Piagetian programs (d=1.28) and formative evaluation (d=0.90) carry some of the largest effect sizes in the dataset.

What does the 0.40 hinge point mean in Visible Learning?
The 0.40 hinge point is the average effect size of all the interventions Hattie studied; each influence is judged against it.
John Hattie found that the average effect size of all the interventions he studied was 0.40. He therefore decided to judge the success of each influence relative to this value, which he called the hinge point, so that an influence is read as stronger or weaker than the typical intervention in the study. He used the hinge point to answer the question of what works best in education.
Has the list of influences in Visible Learning changed since it was first published?
The original list of 138 influences was later updated to 150 and then to 195.
Yes. Hattie first ranked 138 influences on learning outcomes. He later updated that list to 150 effects in Visible Learning for Teachers, published in 2011, and more recently to a list of 195 effects.
