He repeated the method of ranking influencers using the “hinge point” measurement which allowed him to rank the effects of 195 influences on a scale. 15 years research involving millions of students and represented. In the 2015 Visible Learning, Hattie rated influence effects by increasing the number of meta-analyses from 800 to 1200. John Hatties ground-breaking book Visible Learning synthesized the results of more than. ![]() It was the effect size of 0,4, a numerical conversion that Hattie termed as his “hinge point,” that became the effect size average. Hattie has headed a team of researchers for 20 years who have trawled the world. In the 2009 edition of Visible Learning, Hattie suggested that an effect size of 0,2 could be relatively small, while an effect size of 0,6 could be large. This is a graphical version of the list in John Hatties Visible Learning. This unique and ground-breaking book is the result of 15 years research and synthesises over 800 meta-analyses on the influences on achievement in school-aged students. His research interests include performance indicators, models of measurement and evaluation of teaching and learning. ![]() The greater the size of the effect, the greater the influence. Professor John Hattie is a researcher in education. The size effect could be numerically converted for purposes of comparison, for example, an influencer’s effect size of 0 shows that the influence has no effect on student achievement. ![]() Aggregating the data that was generated from these meta-analyses, Hattie determined the size of the effect each influence had on student learning. ![]()
