observations of a High School Sub-@#!&%

I have been teaching a class called early childhood development to a tough group of kids. I have spent several weeks with them now, and we have made great progress. We have been talking about positive & negative reinforcement. I decided to show the kids a practical application of this method to achieve desired behavior. I have been addressing the "language" in this class. So I told my students that if the entire class could make it through an entire block without ONE swear word I would bring in Krispy Kreme donuts. (and I had to explaine it was what I considered as a swear word!) Anyway.... a few students were not paying attention. At this point my one male student pipes up "d!@#%it class listen to Mrs. Hucko I want those donuts!" I'll let you know when...or if they finally earn the sweet treat, until then I try to keep a straight face on the outside while I am laughing (or some days crying) on the inside!
