WITHOUT APOLOGY
Probably without realizing it, teachers apologize about their material regularly. "I know this is dull/hard/uninteresting, but let's just get through it." These comments tend to come from low teacher expectations about subject standards. Figure out why you're teaching what you're teaching (there must be a good reason!) and then stick to it. Your goal is for students to engage in rigorous college prep content, so plan for it and don't apologize. Non-apology phrases sound more like, "The deeper we get into this topic, the more exciting it becomes!" "Other students don't learn this until college, and you'll have in down this year!"
