November 26, 2013International test scores: Getting the data straightMartin Carnoy and Richard Rothstein: Earlier this year, we published an analysis of international test score data in which we showed that these data hide many complex issues, and that glib conclusions regarding the meaning and policy implications of international test data should be avoided. We showed that it is more appropriate to compare student performance across countries by comparing students with similar social class backgrounds, and we showed that comparative information is more useful if it includes test data trends over time as well as levels in the current year. We also presented apparent anomalies in test data (for example, periods in which performance on one international test goes up but performance on another international test, purporting to measure the same subject, goes down, or carelessness in sampling methodology) that should caution analysts from relying too heavily on test score data.Related: www.wisconsin2.org Posted by Jim Zellmer at November 26, 2013 12:20 AM Subscribe to this site via RSS/Atom: Newsletter signup | Send us your ideas Comments
