What makes a good teacher?

I think a good teacher is someone who is passionate about what they are teaching, knows their stuff, and makes an effort to connect with their students. They have reasonable expectations of their students, they don't expect perfection but they do expect effort, they challenge their students as individuals rather than as a group. I think good teachers take a little bit of extra effort in their lessons, they don't just give Powerpoints and have someone else recite the material as they sit at their desks and read a magazine. Good teachers are often discouraged by current practices in public education, such as teaching to a test, because they don't allow much room for their own material and often have irrelevant content. My best teachers were not afraid to give supplemental instruction outside of class in a fun way, I enjoyed going with my Art Teacher to the museum on a saturday, or listening to an extra lesson my History teacher gave after school about how to be a smart voter.
