  1. It looks like bulkying has a positive effect: 0.24 on the site with all the rankings, but in an article quoting Hattie (I think) he said this was a negative effect: -0.24. This seems like an important one to correct or clarify.

      Dear Dante,
      Thanks for pointing this out.
      I found the Hattie interview you mentioned: http://www.workingoutwhatworks.com/en-GB/Magazine/2015/2/John_Hattie_interview Hattie says: “Yes I am now close to 1200 meta-analyses (up from the 800 in VL). What is remarkable since I published the first study (in 1989 based on 134) is that the “story” underlying the data has hardly changed. Some of the more interesting (new) effects include Bullying (-.24), parental employment (.03), sleep (.07), single sex compared to coed schools (.08).”
      But the data I visualized is based on this paper: “The applicability of Visible Learning to higher education.” There, Hattie lists “bullying” with an effect of 0.24. http://psycnet.apa.org/journals/stl/1/1/79/
      Unfortunately none of the two texts provides the original meta-study to double-check the effect size. We should ask John Hattie for clarification.
      Best wishes,
      Sebastian
