In at the deep end: teacher training during a pandemic

I can’t speak for all new teachers, but I grieve the time I have missed. The freedom to learn and review mistakes and new methods found in initial teacher training is a gift. Having the time to hone skills and track your progress with a mentor is valuable time lost. It has been easy, therefore, to feel underqualified and like an imposter among other teachers. How am I supposed to be a great teacher when I still have so much to learn? What about the students I am teaching now; will their education be worse because of my ability to teach?
