Remember not include students' names. As the teacher I am supposed to set the example and be the disciplinarian. I am supposed to always maintain order. I find it difficult when you have a few clowns in the classroom and they are truly funny.
Laughter is sometimes hard to keep in.
I try but sometimes a students says something that is truly funny and the whole class erupts in laughter and guess what, I do too. I can truly say that sometimes a bit of laughter is the only thing that keeps me from breaking. I suppose that it means a lot to students that the teacher is willing to tell a joke , laugh at himself or along with the students. I feel that you can be a disciplinarian and laugh with the students as well. To this day I still remember my physics teacher and the fun we had in class.
