Value Added Productivity Indicators: A Statistical Comparison of the Pre-Test/Post-Test Model and Gain Model.
Weerasinghe, Dash; Orsak, Timothy; Mendro, Robert
In an age of student accountability, public school systems must find procedures for identifying effective schools, classrooms, and teachers that help students continue to learn academically. As a result, researchers have been modeling schools and classrooms to calculate productivity indicators that will withstand not only statistical review but political criticisms. There are two main approaches to this problem; one uses pretest and posttest scores of students and the other uses student gain scores. In this paper, a model is developed for each approach, and their results are discussed. The outcomes of each model are School Effective Indices (SEI) and Classroom Effective Indices. A set of criteria is established and the SEIs these models produce are tested against these criteria using hierarchical linear modeling (HLM) to determine the "better" approach. It is suggested that both models produce very similar results. If HLM software from SSI Inc. is used, then the pretest-posttest two-level model is more convenient and efficient to use than the three-level Gain model. (Contains four tables and six references.)
