1. What has 30 years of evidence in education shown us? John Hattie University of Melbourne

2. 1. The contested nature of “evidence”

3. 2. There is a practice of education Almost everything enhances achievement

4. 2. There is a practice of education Almost everything enhances achievement • We know some of the low and high influences • The quality of moderators in articles is poor • .4 is an average not a minima

5. 3. We are obsessed with surface level knowing Learning strategies 90+% are surface Teacher questions 90+% are surface Lesson observations 90+% are surface Test analyses 90+% are surface Visible Learning 90+% are surface We privilege a surface grammar of schooling

6. 4. I am an EVALUATOR of my impact • Nature • Magnitude • Pervasiveness • Causes

7. 5.Scaling up • Autonomy is the basis of teacher professionalism • Children/my class is unique • Sparse literature on scaling up • The power of licensing

8. 6. We continue to ignore the evidence • Biggest critics are the “experts” • Politicians, parents, teachers want the structural influences that support them and leave them alone to get on with the task • Educators are not prepared to back excellence in their profession

9. 7. There is a future • The move to collect teacher judgements not collecting test scores • Seeing tests as feedback to teachers • Seeing score reporting as the start (not end) of testing • The move from debates about outcomes to evidence based on scaling up • The recognition of “collaborative action” across & within schools over teacher autonomy • Re-litigating the purpose of schooling • years growth for years input • learning and growth as much as achievement

10. The growth of “knowing thy impact” • Competing models of influence • Evidence as probabilities • Growth of qualitative synthesis • New models of teaching Diagnose InterventionsEvaluate Teaching is
