Changing a thing or two

My faculty adviser came on Tuesday to watch one of my lessons and wow was it ever chaotic. The way that i organized the class made a lot more work for myself. I was not very happy with how the lesson went. The students were all over the place and making a mess with the experiment that i had planned. Overall i did not feel so great about the lesson after.
The next day i was able to teach the lesson again to the other class. I decided to change a few things about the lesson and how it was set up. One of the big things that i changed was how i instructed the students. I went over the entire experiment with the class and answer any questions they had before we started. That made a HUGE difference in how the lesson went. After this attempt at the lesson i was very happy with how it went and was really excited to see how big of a difference it makes to change even the tiniest thing.
My co-op told me one time that usually if a class is bad during a lesson it is because of your directions and not the students. This was the case in my lesson and i was directly able to see that on Wednesday!
