The message behind this book can be summed up into these words.
Educators, know thy impact! -Hattie
In this book, Hattie shares the result of what must truly be the most exhaustive meta-analysis in education. As a result, we can gauge not only the effectiveness of over 150 educational interventions but we can then compare thee interventions on a scale of what Hattie calls a "hinge point" of .40
Anything above this point has more of an impact than a typical year of student growth. An effect size of 1.0 is the equivalent of advancing the student's achievement by a full grade.
Many of the strategies I have used in my classroom over the years feel far short of Hattie's "hinge point." The number one strategy was feedback.
I participated in a book study with my colleagues at #edcoach and we virtually discussed the book each week. While John Hattie never joined us in our chats, Grant Wiggins tweeted with us one night as we discussed feedback. He is working on an article for ASCD about feedback and shared his thoughts on why this strategy is so impactful.
One of the members of my PLN Maureen Devlin did an amazing job of blogging during our study. If you would like to learn more about how this amazing educator is using what she learned during our study, check out her Pinterest site.
Below are the rank ordered list of the most impactful factors according to Hattie's work. I have highlighted the one's that would pertain to the general ed population in the United States.
- Student self-assessment/self-grading
- Response to intervention
- Teacher credibility
- Providing formative assessments

- Feedback
- Reciprocal teaching
- Teacher-student relationships fostered
- Spaced vs. mass practice
- Meta-cognitive strategies taught and used
- Acceleration
- Classroom behavioral techniques
- Vocabulary programs
- Repeated reading programs
- Creativity programs
- Student prior achievement
- Self-questioning by students
- Study skills
- Problem-solving teaching
- Not labeling students
- Concept mapping
- Cooperative vs individualistic learning
- Direct instruction

The next two on the list in rank order....
“Home environment” and “socio-economic status.” This means that all of the other factors listed above have a greater impact than these factors. Interesting.
