Although the terms teaching and learning are typically paired, those of us who teach know that students don't always learn. When I complained about this early in my teaching career, a colleague chided me: "Saying 'I thought the students something, they just didn't learn it' is akin to saying 'I sold them the car, they just didn't but it'".

Student engagement is the product of motivation and active learning. It is a product rather than a sum because it will not occur if either element is missing.
