The premise of the book is that, “Every student deserves a great teacher, not by chance, but by design” and that we (teachers) need to know the effect of what we are doing in our classrooms in regards to student achievement. For example, the effect size for class size is 0.21 and the effect size for metacognitive strategies is 0.69. Hattie states that teachers should consider classroom work with an effect size of 0.40 and above when designing learning for students. Teaching is hard work.

The researchers write, “After all, if students don’t get to verbally explain, pose questions, and narrate routinely, it’s going to be much more difficult for them to do so in writing.” The effect size of (more…)
