A great teacher is someone who walks in their classroom expecting to be challenged by their students. A great teacher is not just in the teaching business, they are in the talent seeking and interest building business. You use what a student is best at, and what they want to learn about, to teach them what they need to learn to be successful in their future. You realize that their future doesn’t end with next week’s test. A great teacher knows that knowledge is something that is to be retained, remembered.
