Just looking at the responses of my colleagues in this class, one can run through all of them and pick up very good points that would improve teaching for each and every one of us. Even then, we would probably differ in where we lay emphasis.
Good teaching, for me, means awakening the potentialities inherent in each and every human being. Everything else comes second to that. I may never know that the potentialities have been awakened. I may recognize years later that a student has been positively affected by my teaching. Merely scoring high is not necessarily a good measure of awakening the potentialities, although it is necessary (for purposes of accountability) that we encourage students to perform. High grades also ensure continued growth in one or more fields that the student may choose to follow. The acquisition of good marks without cheating is one of the major aims of education. And so, I would look at the student's longer lifetime to see whether there has been anything that I did or that I encouraged during class that has rubbed off in the student.
In the final analysis, it is the students' contribution to the well-being of society by which we should measure the value of our contact with them. The details of how to achieve this may, indeed, differ from one teacher to another. But the overall goal never changes.
