In math and science, maybe more than any other subjects, it is important that teachers be realistic and refrain from blaming themselves for all failures. This is counterproductive and takes time away from constructive efforts. This does not suggest that teachers should give up on these students. An honest, unemotional self-evaluation of the methods a teacher is using can lead to incremental improvement with time. Keeping a journal with thoughts on the success of lessons, the employment of classroom management techniques, and new ideas for later classes is an excellent way to ensure improvement. This chapter discusses some other ideas to help teachers succeed in their lessons.
