Listening to Myself Teach

I had to listen to an audio transmit of myself teaching a lesson and then write down everything I said. I had to what down every and, like, um and ah I said. I surprised myself because I did not have have a lot of those words. The one word that I used quite often was "so". I also noticed that I need to improve my feedback; for every student I gave feedback to, I said "Good Job". It got very repetitive. I think that my voice was strong and loud enough. There were some instances where I was not very clear, I did not even know what I was saying. It is so weird listening to yourself speak, I am going have to get use to it.
