## Professor John Hattie’s Table of Effect Sizes - The.

Overall, Hattie finds that the effect size of homework is 0.29. Thus a media commentator, reading a summary might justifiably report: “Hattie finds that homework does not make a difference.” When, however, we turn to the section on homework we find that, for example, the effect sizes for elementary (primary in our terms) and high schools students are 0.15 and 0.64 respectively. Putting it.

We know the effect size of technology remains low and has been so for the last 50 years. As Dylan Wiliam has often said, technology is the revolution that is still coming! T he effect of distance learning is small (. 14) but that does not mean it is NOT effective —it means it does not matter whether teachers undertake teaching in situ or from a distance over the internet (or, like when I.

When implementing a new program, an effect size of 1.0 would mean that, on average, students receiving that treatment would exceed 84% of students not receiving that treatment. Hattie’s work is based on educational innovations. Research shows that these can be expected to have an average effect size of 0.4 (the “hinge point”). Innovations tend to capture the enthusiasm of the teacher and.

Hattie found that the average effect size of all the interventions he studied was 0.40 and therefore decided to judge the success of innovations and influences relative to this 'hinge point'. Hattie identified six main areas that contribute to learning: the student, the home, the school, the curricula, the teacher, and teaching and learning approaches. He worked through each of these.

Another answer to 'why class size effect sizes' are low, is pretty obvious when you look at the tables above. Hattie derives his lowest effect size of 0.09 (incorrectly). Then w hen you average very small effect sizes from class sizes of 40 down to 30 with large effect sizes of 20 down to 15 you get a low average.

In John Hattie’s research, he claims the effect size of homework is only 0.29. In other words, it makes little difference. He claims that too much emphasis is placed on it. 5-10 minutes of practicing what was taught that day at school has the same effect as 1-2 hours does. However, that is not the full story, and homework in secondary schools specifically has an effect size of 0.64. The.
