A New York Times opinion piece here discusses a suggestion by the Sec. of Education and Bill Gates that good teachers be paid more for teaching larger classes.
As a teacher for 37 years, I don’t believe in any research ginned up that shows class size doesn’t matter. It’s like saying that living in a decent house or apartment doesn’t matter (
Research shows that people living in cardboard boxes are just as happy . . . ). Or saying that having loving parents doesn’t matter ( One study shows that abusive parents produce children who are more resilient . . .)
Good teaching K-12 always involves building a good relationship with students. Just try it in a classroom of 38 kids.
