The Web site of Carnegie Learning, a company started by scientists atCarnegie Mellon University that sells classroom software, trumpets this promise: “Revolutionary Math Curricula. Revolutionary Results.”
The pitch has sounded seductive to thousands of schools across the country for more than a decade. But a review by the United States Department of Education last year would suggest a much less alluring come-on: Undistinguished math curricula. Unproven results.
The federal review of Carnegie Learning’s flagship software, Cognitive Tutor, said the program had “no discernible effects” on the standardized test scores of high school students. A separate 2009 federal look at 10 major software products for teaching algebra as well as elementary and middle school math and reading found that nine of them, including Cognitive Tutor, “did not have statistically significant effects on test scores.”
Amid a classroom-based software boom estimated at $2.2 billion a year, debate continues to rage over the effectiveness of technology on learning and how best to measure it. But it is hard to tell that from technology companies’ promotional materials.
