Changes in the Students

Before finishing my observation, there is some problem that I encountered. The only problem that I think I encounter is the suspension of classes because of the weather condition. That is why completing my observation for 20 hours is a real struggle. 
The students on my first day of observation are noisy and they didn't greet me a good morning, well that is ok for me because I was just having a favor to them. But then my resource teacher told them that I will be a future teacher too so they should greet me. On the second day of my observation, the students greeted me a good morning with enthusiasm. Little by little the students lessen the noise in the classroom. Until one day, I entered the classroom with very quiet students until the last day of my observation. My resource teacher used some strategies to lessen the noise in the classroom. For example, writing the names of those who cause noise. I thought this strategy will not work but it worked. The students behave well they don't need to be disciplined using punishment.
The students are participative in the discussion. They are also industrious students. They like being asked to do something.
