A good teacher has a solid understanding of the material, a clear presentation style and a fair assessment system that is clearly comprehensible to the students. An excellent teacher brings all of that to the classroom and realizes that each student is a unique individual who has their own goals and needs and is prepared to work with each one to give them the optimal learning experience.
