Just this week. I have a student in Grade 5 that is pretty oppositional, has a tough home life, etc. He doesn't always try very hard, but sometimes I can see he's trying to put in some effort. We were talking about how I grade them, and he interrupts the conversation with... "I don't care at all about my grades..." And I thought 'here we go, another rant about how unfair school is...' "I just want to know that I keep getting better." Perfect. I got chills.
