John Hattie’s done a lot of research on education and he suggests this…
- The one metric worth looking at is year on year progress. One school year input should lead to one school year progress.
- Stop comparing school performance against each other. Look at each school and try to reduce the variability in performance within schools. Even very bad schools will have very good performers. Try to learn from the very good performer within that school.
- Stop with interventions. There is no silver bullet. Most interventions have very low effect sizes, except for one intervention. See 4.
- Collaborate. This has the most promise. Within schools, let bad teachers learn from good teachers. Let good teachers feed off each other. Admin should be built around letting good teachers hone their practice.
