Early in his career, Paul Romer helped solve one of the great puzzles of economics: What makes some economies grow faster than others? His “new growth theory” might one day earn him a Nobel prize.



Then a decade ago, Romer, by then a professor at Stanford University, decided to tackle what may be an even tougher puzzle: Why were so many of his students coming to class unprepared and disengaged?



Romer’s quest began with the proposition that the more time students put into their studies, the more they learn. As Malcolm Gladwell demonstrates in his new book, “Outliers,” that’s certainly true in many other areas of human endeavor — the more you practice scales or swing a club, the better you are at playing piano or hitting a decent golf shot. Why should learning economics be any different?



It took some noodling around, but two years later, Romer raised $10 million in venture capital to start a software company he called Aplia. The idea was to develop interactive exercises that students could do in conjunction with the most widely used college economics textbooks. Students would answer questions, then get immediate feedback on what they got right and wrong, along with some explanations that might help them get it right on a second and third try. Aplia’s team of young Ph.D. economists and software programmers also devised laboratory experiments in which the entire class could participate in simulated markets that give students a practical understanding of concepts like money supply and demand curves.

Locally, the Madison School Board is discussing a proposed technology plan this evening. Ideally, before any more is spent, the Infinite Campus system should be fully implemented, and used by teachers, staff and students. Once that is done, there are many possibilities, including this example.
