I remember in 7th grade when all the math teachers had the exact same rather unique style of grading that they couldn't have all came up with the same system on their own. I was observing two middle school classes for 8th grade science this year and both teachers had the same presentation. Do they do this just because it is easier to work as allies, or is there a reason they have to do it this way? I actually really would rather not copy someone else's grading style when I start teaching, and I don't know about lectures such as SmartBoard and PowerPoint presentations. It is a pain to come up with all of them yourself, but some of them I don't like and if I was the teacher would have made up my own or found another one on Web 2.0 Tools.
