One of the big things that I use in my classroom early on is the notion of solidarity. I tell the kids early on and try to emphasize that everything I ask them to do in class, I do with them or have in my handwriting. If they are writing in journals, I write in my journal. If they take an AP multiple choice passage, I show them the passage I've taken. If I require them to read a book, I show them the book I'm reading.
In doing so, there is a sense of community that, I feel, cuts down on behavior issues. In addition, by writing and reading with the students I'm telling them that what we do is important. It's important not because I said to do it, but important because I'm taking the time to do it. Does it mean that I have to structure my day differently to get the grading in? Yes. However, it cuts down on discipline issues and makes me more aware of the cognitive processes that I require of my students. It provides me with a greater sense of timing and problems in my lesson design.
