Letters: Examining the Studies

Re “Guesses and Hype Give Way to Data” (Sept. 3): The quality of conclusions drawn from data depends upon the study that produces it. The study of Upward Bound conducted by Mathematica is a case in point.

Its conclusion that Upward Bound has “no effect” has been repudiated by much of the educational opportunity community, including a statistician at the Department of Education who argued against its publication. Yet this article presents it as the first major achievement in the use of randomized studies in the field of education.

I have directed an Upward Bound program since 1990 and have seen it do wonders. Randomized studies make sense when it is feasible to limit the impact of diverse variables. When attempting to assess programs that impact a wide range of intellectual and social abilities over time, this method must invariably fall short.

TO THE EDITOR:

Educational research uses all sorts of approaches to get at the complex issues involved in education and schooling, and “crunching numbers to evaluate impact” is but one of them. A cursory glance at the materials produced by the American Educational Research Association (AERA) would reveal this fact.

It is true that much of educational research is not as rigorous as it needs to become, but rigor is not the same thing as crunching numbers. AERA has been working to integrate all approaches to educational research by both honoring their validity and demanding their integrity.

Meanwhile, we have a real-life story in the transformation of Finnish schools, based on increasing teachers’ knowledge and understanding of their subject matters. In this case, history and historical method reveal something that the studies in the article did not.

[News & Analysis] Epidemiology: Budget Woes Threaten Long-Term Heart Studies

Science 16 August 2013:
Vol. 341 no. 6147 p. 701
DOI: 10.1126/science.341.6147.701 Epidemiology The Framingham Heart Study is an icon of epidemiology. Its long-term monitoring of a large group, or cohort, of people in a Massachusetts town has yielded landmark results on everything from the link between cholesterol and heart disease to the genetic risk of stroke. But this year, the thorough clinical exams that participants periodically receive will be scaled back, and plans for new tests put on hold. Similar cohort studies sponsored by the National Heart, Lung, and Blood Institute are confronting a similar fate and some observers suggest that the era of such large, costly long-termstudies is drawing to a close.
