Extrinsic motivators dominate classrooms even though research clearly shows why they shouldn’t. Most schools motivate students to learn with external rewards or punishment. But decades of research, both about educational best practice and the way the human brain works, say these types of motivators are less effective. Students learn better when they are intrinsically motivated. The Met high school in Providence goes to the extreme to tap into students’ intrinsic motivation, letting them study what they’re most interested in. It’s difficult to pull off this type of school design, but by many indicators, it’s worth it.
