At the beginning of the school year, I hand one of these out to every student. I ask them what it means to be a good learner before we discuss it at all. Our school is very focused on visible learning. Then I hang these up around the classroom!
(Some answers I would hope to see resemble the acronym for LEARNERS: Learn from mistakes, evaluate work based on success criteria, ask questions, receive and respond to feedback, never give up, effort matters, reach goals and state what I am learning)
