I asked a group of former cohort members what we, as a university, could have done better to prepare students for the being a teacher. One student's answer stuck with me. "I wasn't ready for the loneliness. As a cohort, we were a community. You played a small role but it was us as a leader but, sorry, John, it was us. We were tight. Then you enter the field and you're on your own. I just wish I worked at a place where we ate together and planned together and had a couple of drinks together on Friday night like we did as as a cohort. I miss that so much." I'm not sure how you define PLC but it's not "a group of people who analyze data together." It's what she was describing. It's a community that talks shop on a Friday afternoon after work.
