This document discusses John Hattie's research on visible learning and high-impact teaching strategies. Some of the highest effects on student achievement according to Hattie include teacher-student relationships, feedback, direct instruction, and meta-cognitive strategies. The document provides information on how to apply these findings, including ensuring clear learning goals and success criteria are communicated to students, using feedback to help students know how to improve, and gathering feedback from students on their learning. The overall message is that teachers can positively impact student outcomes through building relationships, setting high expectations, and using data and feedback to guide instruction.
