I'm in the midst of a LTS as a new math teacher. One of the courses that I'm teaching is Pre-Calculus. I never thought that I would be teaching Pre-Calc this early in my teaching career. I sometimes feel like a fraud, like I don't know enough math to teach this course (and I have learned a lot of new teachers feel this way). I work very hard to prepare for my lessons and teach myself what I am teaching. I have also worked hard to build a great relationship with my students. As a new teacher I knew that would be my biggest strength. However, yesterday I made a total flub/fool of myself because I couldn't answer a student's question. I fumbled horribly trying to answer the question. Though I work extremely hard, I know that sometimes my lessons aren't the greatest and could be better. All the teachers at my school have been extremely helpful and told me that everything I'm experiencing is normal and first couple of years you just roll with the punches and do the best you can and find what you're good at and what you need to improve on; what works for you and what doesn't, etc... I guess I'm posting because I needed to get the fact that I messed up off my chest and two wonder how you recover from something like that? I feel like I've lost credibility with my students.
