In this passionate teaching speech, Neil deGrasse Tyson breaks down what makes for a good teacher. He discusses the memorable teachers he's had over the years, and is disappointed that the number isn't higher (since he's had over 80 teachers). Tyson discusses the changes he would like to see in terms of education.
The thing that makes a teacher memorable, or makes them have a lasting impact on a student is their passion for the subject they teach. If a teacher can pass on their own excitement or enthusiasm for a subject onto a student, they are a good teacher. He says that there should be less focus on curriculum and methods, and more emphasis on the importance of teaching with passion.
