the mind blowing achievement of john hattie – or, we know how to run schools

We often act as if running a school is a mysterious thing. It’s not. There have been thousands of studies looking at every sort of education policy. John Hattie is an educational researcher in Australia who took the time to collect data from thousands of studies and do a meta-meta analysis to figure out what works.

He has a number of books and articles that summarize his findings. Below, I have included a diagram where he standardizes the effects of 195 factors that might affect achievement and ranks them. Major take home points. Here is what predicts achievement in a big way:

  • Prior performance – by far, the biggest predictor of future achievements are estimates of past work (#1 teacher assessment, #3 self reported grades).
  • Process oriented learning (“Piagetian programs” – don’t focus on outcomes, but on how you get the outcome – #4)
  • Teacher practices aimed at individual students – such as intervening directly disabled pupils (#10, #11), micro-teaching (e.g., one on one interaction with students – #9),  and integrating classroom discussion (#10).

What clearly has a negative effect?

  • Home corporal punishment (#193)
  • Television watching (#192)
  • Summer vacation (#190)
  • Student depression (#195)

What has surprisingly small effects (defined as about .1 or less)?

  • School type – being in a charter school, a single sex school, or learning at a distance (all have nearly zero effects)
  • Mentoring
  • Student diversity
  • Teacher credentials

In other words, the baseline is student ability, which determines who well they do. But you can also get big effects through hands on, processed based, and interactive learning. You should avoid disruptive things, like vacations or television, and the school and teacher credentials don’t get you much.

Thank you, John Hattie.
