What indicators show the teachers that they are on the right track or that they must make a change?

The laser focus on one’s impact answers this question as to whether they are on the right track. Using evidence about student’s work, the way they are learning, their pace of learning, the way they react to errors confusion and mistakes are all part of knowing whether the student is learning. It involves stopping talking and listening to students, privileging their voice about their own impact, and setting tasks to help answer the impact questions” (John Hattie, personal communication, July 24, 2016).
