Who was your best teacher, law or otherwise? What made that teacher so effective? For the past four years, we have posed these questions at conferences, law schools, and to groups of Chilean, Georgian, Ira ni an, and Turkish law teachers. In response, law teachers have described their best teachers’ attitudes, expectations, teaching methods, mental habits, beliefs about students and learning, personal qualities, teaching emphases, and anything else that made their teachers so noteworthy. The results have been strikingly similar. Across cultures and schools, the best teachers distinguish themselves by their thoughtfulness, caring about their students, high expectations, commitment to student learning, and ability to engage their students.
