Today we were supposed to do a fun activity about sampling a species found in an ecosystem. This isn't exactly what we are covering, but I was going to discuss why you would want to sample a species and what kind of scientists would do it. This class has given me issues all year long. I recently removed their free seating and they are still acting up. My other classes are doing fine and dandy but the students in it just push my buttons. The other day I went to get a drink of water and would be 20 seconds late after the bell, and I came back to a student making very loud obnoxious monkey noises. Granted that is one student and he is now sitting right next to my desk. I know it is getting towards the end of the year and it will be difficult but I want to bring the hammer down on this class. Giving a weeks worth of book work and notes and no group work may seem to be the kind of consequence needed. I was feeling good about this class all until a few weeks ago. I was getting them back on track and I did nothing different but, they fell off. How do you deal with your rowdy classes?
