Never apologize for or otherwise undercut the argument you've made or leave your readers with the sense that "this is just little ol' me talking." Leave your readers with the sense that they've been in the company of someone who knows what he or she is doing. Also, if you promised in the introduction that you were going to cover four points and you covered only two (because you couldn't find enough information or you took too long with the first two or you got tired), don't try to cram those last two points into your final paragraph. The "rush job" will be all too apparent. Instead, revise your introduction or take the time to do justice to these other points.
Above all, teachers need to inform themselves and the rest of the school community so that together they can develop a policy to discourage bullying. By educating themselves about bullying, teachers and parents have the knowledge to set up effective programmes and structures both within the classroom and for the whole school. Furthermore, by removing the opportunity for children to bully, providing children with a stimulating environment, and giving them the tools to deal with conflict appropriately, teachers can reduce children's inclination to bully. Although bullying will never be fully eradicated and must be dealt with as soon as it occurs, increasing awareness of the problem is making schools a safer and more enjoyable environment in which children can learn.
