Visible Learning Research

What matters most in improving student achievement and progress?

John Hattie Headshot

John Hattie’s work is based on his meta-analysis of more than 1,000 research reviews comprising more than 80,000 studies involving more than 300 million students around the world.

Hattie found that the #1 most effective method for improving achievement was collective teacher efficacy (1.57). Watch this webinar of our expert, Kristin Anderson, to understand more about the Visible Learning research and Hattie's new #1 effect size: collective teacher efficacy.
