I think it depends on the type of motivation, when I think back to my time at high school (Australia in the 90's) there was a contrast between how English was taught and how Math was taught.
In my English class the teacher would assign the class a book, or a poem etc. Take this home and read to the end of chapter X before next class. At the start of next class the teacher would pick half a dozen random students and ask them questions in front of the class about what we had been assigned to read. These weren't the kind of questions you could bluff an answer to.
Believe me you were motivated to do the readings because no one wanted to get called up to the front of the classroom and look like an idiot by not being able to answer the question. You were motivated by fear.
In Math on the other hand we were given a textbook, told to go home and do exercises from the book to practice what we'd been taught. It entirely ran on the honor system no one checked to make sure we did the exercises, as a result I know a large portion of the class didn't bother. I wonder what would have happened if the math teacher were to have called up random students to front of the classroom and made them solve a problem on blackboard at start of each lesson.
