John Hattie published Visible Learning in 2009. It the analysis and synthesis of a mind boggling amount of data from over 800 meta-studies. There are vast amounts of information to be found on Visible Learning and one source I found particularly helpful is the link below. The slideshow gives explanations of what the numbers mean (the effect) on p.11 and what teachers should aim for p. 15-17. He suggests "the teacher must make calculated deliberate interventions to ensure there is cognitive change in the students."
“Visible teaching and learning occurs when there is deliberate practice aimed at attaining mastery of the goal, when there is feedback given and sought, and when there are active, passionate, and engaging people (teacher, students, peers) participating in the act of learning.”http://aotawhiti.school.nz/wp-content/uploads/2014/06/HattieSession1.pdf

It is my understanding that this approach is primarily about educators evaluating themselves and gauging the effect and productiveness our teaching has on students. By taking action when a student is struggling and actively participating in the learning process, the teacher becomes an Activator of knowledge. Its about analyzing what is working and what is not for the students and adapting our methods and attitudes to help students reach levels of achievement that are equal to and exceed their potential. Know thy impact is when we evaluate the impact of our teaching on the students.
Examples of highly effective visible learning strategies are:
- self reported grades - students predict their own grades
- setting appropriate challenges and goals
- providing opportunities for students to peer review and learn from each other
- supply worked examples
