You may be a five-star chef, but if you are given rotten meat, sour milk, spoiled vegetables, and moldy potatoes, it’ll be hard to prepare a decent meal that will pass Health Department requirements.
My sister is an outstanding math teacher and gets excellent results from some of her inner city ghetto kids. But most of them have zero work ethic and want nothing more than to make it impossible for all kids to learn. The parents expect the teachers to magically teach, but do not expect their kids to make any effort to learn.
It takes an educator with the talent to awaken a student's desire to learn that results in higher student scores. The notion of an "outstanding teacher" lies in the teacher's ability to educate.
Amen.
