ABSTRACT
Teachers who have set themselves this goal and are consistently trying to implement it are fundamentally different from teachers who do not ask themselves this question. "Visible Learning" and "Know thy impact" become the core message of this mindframe. This chapter explains the progress from proficiency to enhanced achievement. It also explains the evidence of the factors "providing formative evaluation" and "response to intervention." The chapter helps to explain what is meant by the notion "Teachers are to DIE for." It also helps to explain how individual feedback works. We must ensure each student progresses in his or her achievement journey across the usual school disciplines. Whatever the content, the progress is the critical task we ask of teachers and students. Using effect sizes invites teachers to think about using assessment to help to estimate progress and to reframe instruction to better tailor learning for individuals or groups of students.
