Evidence-based education is when teachers use a mix of research and classroom experience to inform what they teach, how they teach it and how they assess their students. For example, an evidence-based teacher might use data collected from past student performance (like test scores) to select materials to teach and activities that have proven to be the most effective in helping students learn the material. They might track how well students are doing with activities and tests, and then use that data to tweak their course and make sure students are getting the best education possible. In short, evidence-based education means using scientific research to inform the decisions a teacher makes in order to provide the best learning experience for their students.
