“In 2009, the Bill & Melinda Gates Foundation launched a massive project to study 3,000 teachers in seven cities and learn what made them effective. The five metrics that most correlated with student learning were:1. Students in this class treat the teacher with respect.2. My classmates behave the way my teacher wants them to.3. Our class stays busy and doesn’t waste time.4. In this class, we learn a lot almost every day.5. In this class, we learn to correct our mistakes.”

“Consider now the primal scene of education in the modern elementary school. Let us assume that a teacher wishes to inform a class of some 20 pupils about the structure of atoms, and that she plans to base the day's instruction on an analogy with the solar system. She knows that the instruction will be effective only to the extent that all the students in the class already know about the solar system. A good teacher would probably try to find out. 'Now, class, how many of you know about the solar system?' Fifteen hands go up. Five stay down. What is a teacher to do in this typical circumstance in the contemporary American school?"If he or she pauses to explain the solar system, a class period is lost, and 15 of the 20 students are bored and deprived of knowledge for that day. If the teacher plunges ahead with atomic structure, the hapless five—they are most likely to be poor or minority students—are bored, humiliated and deprived, because they cannot comprehend the teacher's explanation.”

“The quality of the relationships that students have in class with their peers and teachers is important to their success in school.”

“Will non-English-speaking students start speaking English because their teachers were fired? Will children come to school ready to learn because their teachers were fired?It would be good if our nation's education leaders recognized that teachers are not solely responsible for student test scores. Other influences matter, including the students' effort, the family's encouragement, the effects of popular culture, and the influence of poverty. A blogger called "Mrs. Mimi" wrote the other day that we fire teachers because "we can't fire poverty." Since we can't fire poverty, we can't fire students, and we can't fire families, all that is left is to fire teachers.”

“School is like theater. Teachers are like directors, students are like actors, and classes are like theatrical presentations.”

“A wise teacher learns in the midst of teaching; a wise student teaches in the midst of learning.”
