By Lisa Guisbond. Growth models are pitched as a thoroughly modern, scientific way to .answer the age-old parental question: “What did you learn in school this year, my dear?” It seems reasonable enough: Test students at the beginning and the end of the year and measure the “growth” in test scores to see if student achievement is improving. Given the narrow and limited nature of the data used to measure this growth, however, there’s often less than meets the eye in the results. Fortunately, there are better, if little known or understood, ways of both measuring and stimulating real growth in learning.
