Something really important has happened for my student. Should I let Mrs. Pesnell know?
It is my belief that parents and teachers should work together as much as possible to ensure that a student's social emotional health is respected, encouraged, and thriving. Therefore, if something important has happened, I would appreciate knowing about it -- the good and the bad! This way, the lines of communcation are opened so that parents and I can ensure that the student is being helped and supported.
By no means am I saying that you must inform me of these events. I also feel that it is my job as a teacher to build a relationship with my students so that they feel comfortable enough with telling me these important things.
