How do I start thinking like a teacher?

I think I have started converting to teacher thought and not student thought. Obviously I still need a lot of student thought so I can be successful in classes, but thinking like the teacher can make learning easier. For example reading a chapter in a textbook can be easier if you think like a teacher. First skimming and looking for things that you believe the teacher would deem important to be on the exam. Now that I've started student mentoring at the Mt. Blue Middle School, it is imperative to start thinking like a teacher. This is great practice in explaining less complicated material so younger children can understand it. Once I get more into my teaching program, I will likely begin thinking more like a teacher and less like a student. It is important, however, to keep the ability to think like a student when I am teaching so I can more easily understand what students need when they are stumped.

How can I keep the mindset of a student and a teacher when I begin teaching?
