Hi all, I'm halfway done with my teacher preparation program...I have about 1 year left. Over the course of this academic year, I've completed 75 field hours and next fall I will complete my final 30 and finally move into student teaching during the second semester of the 2017-2018 academic year. I have certainly learned a lot by physically seeing various classroom management strategies, differentiated instructional approaches, etc. My question is regarding content area. My content area is in the area of Life Sciences (Biology), and today I was able to sit in on a physical science class. The teacher was discussing acceleration, and I definitely understood much of the content, but how did any of you veteran teachers approach content that perhaps you were a bit "fuzzy" with? What do you do if a student asks you a question pertinent to content and you honestly don't know the answer? It's been honestly 10 years since I took a course in physics/physical science, so I guess I am afraid of perhaps when I begin student teaching, I am going to approach a topic that I am a little weak in. What do you do?
