Teachers develop personal principles and maxims that inform their approach to teaching based on their cultural backgrounds, belief systems, experiences, and training. Maxims determine a teacher's motivations and guide their actions in the classroom. A teacher's presentation of content, goals, lesson plans, materials and techniques reflects their philosophy of teaching. Recognizing the maxims that guide one's teaching is an important part of teacher development that can be achieved through reflective practices such as evaluating how one's maxims are working in the classroom.
