Lessons of Moneyball for our Classrooms
January 3rd, 2012Michael Lewis’ recent book-turned-movie titled Moneyball is the story of how Billy Beane of the Oakland Athletics more-or-less defied conventional baseball reasoning to maximize the potential of some highly undervalued players. Though I believe that Michael Lewis over exaggerates both the brilliance of Beane and the ignorance of MLB, he does offer us some interesting approaches that could be easily applied to the way we assign, collect, and evaluate homework.
Beane’s philosophy had essentially three seemingly contradictory foundations. First, you couldn’t trust what you were seeing on the field. He believed that when scouting and recruiting players, scouts were often fooled by things that don’t really matter when it comes to baseball, like how a player looks or appears to behave. Second, you couldn’t trust the numbers and statistics currently employed by baseball teams. Certain statistics like errors, batting average, and Runs Batted In (RBIs) were not accurate (or precise) measurements of a player’s worth or ability because these numbers don’t really capture the complex “language” of what is happening on the field. Third, you could trust certain numbers that seemed to be more precise and indicative of a player’s worth. With the help of a Harvard educated economist, he began to put greater weight on statistics like on-base percentage and slugging percentage. He even utilized statistics that measured a players defensive worth against his offensive worth. In defying the conventional notions, Beane has been able to acquire talented players normally overlooked by teams. He found gold where others merely saw lead.
I think there is a good take-away here for educators. First, you can’t always trust what you see on the surface within the classroom. As mentioned previously, I think we are sometimes disadvantaged by our experience in that we assume that because students struggled with homework or lessons in the past for one reason, then that must still be the case today. Second, some of the numbers we use to evaluate students do not always accurately reflect what they have or have not learned. Test scores are often incomplete tools in demonstrating student growth and learning. And project or homework points can sometimes inflate scores to reflect greater understanding than what is reality. Third, certain numbers might be more precise and meaningful. In the examples of Beane and his economist, they seem to shun some of the traditional measurements of success and failure on the field because they allowed too much room for either subjective judgment (giving an error to a player) or they depended too much on other variables or events.
Here are some potential tools that one could apply. Compare the amount of time and effort you put into homework completion in class to the completion rates of students. Compare the number of resources available to students against their completion rates. Examine completion rates against test performance to find if there is a link between doing the homework and how they do on tests. Survey students and parents to find what they believe to be are the obstacles to homework completion.
Like Beane, the challenge is to re-vision our classroom. It is to de-emphasize the data and numbers that often distract us and search for information that can allow us to more accurately diagnose and treat the problems within our lessons and classrooms. Doing so brings about innovation and change and allows us to see gold where others only see lead.
