It can be a struggle to best help students understand what they are learning or for students to articulate their learning in meaningful ways. This was especially difficult for me starting out in on my teaching journey. Based on how I had been taught to be an educator the best ways to know if students are learning was to give them a test. If they failed, it was their fault and they needed to do better next time. It took me a long time to learn that in the process of learning the teacher and the student need to be partners.
