A Fisherman who casts a net reeps many

Last week I had a brand new experience with my 3rd block class. I had the opportunity to write up a discipline report on 12 of my 16 students. I was the "end all" for me. They had pushed me to the max. After many little antics the last being changing the time on my clocks, erasing key items off of the board and adding names to the missing assignment list on the board ( in the matter of just ~ 2 minutes while the rest of the class was finishing up a bathroom break and I was in the hall waiting for them). When confronted all denied doing it, so I wrote 12 students up for 4 hours of lunch detention. By 4Th block the rumors were flying that I had given them all ISS or that I thrown a desk. How funny. I had 3 parent telephone calls before the buses pulled out of the parking lot at the end of the day. I really started the fireworks. The next day as I stood at the time clock I was called in the office. The relief finally came when I was praised by my administration for standing my ground. My Principal actually called me a fisherman. A fisherman I asked?...I was told that I cast my net out and the fish just came jumping up and in. The guilty party was discovered that day and all write ups were disregard except the guilty party. I am so glad that my administration stood by me. That was a comforting feeling. I have fewer students who like me and I guess I will be receiving a few less Christmas cards ( hahahaha), but I think I will be fine. I have successfully calmed by classroom antics with one swipe of the pen. A pen is a powerful tool.
It is a sad thought that the actions of a few really change the dynamics of a class. These are great kids and up until now had been well mannered. This one student has really caused a discipline overhaul in my room.
