The purpose of the three-year CCSSO study was to design, implement, and test the effectiveness of the Data on Enacted Curriculum (DEC) model for improving math and science instruction. The model was tested by measuring its effects with a randomly selected sample of ?treatment? schools at the middle grades level as compared to a control group of schools at the same level. The study focused on teachers of middle grades math and science in 5 urban districts with a total of 40 middle schools comprising the pool for random selection to groups. The enacted curriculum model drew on prior development of a Surveys of Enacted Curriculum (SEC) data collection instrument and method of analyzing and reporting data on instructional content and practices (Blank, Porter, & Smithson, 2001; Porter, Kirst, Osthoff, Smithson, & Schneider, 1993; Porter, 2002). Recent research studies on effective professional development in math and science informed the development of the DEC model (Loucks-Horsley, Hewson, Love, & Stiles, 1998; Cohen & Ball, 1999; Love, 2000; Garet, Birman, Porter, Desimone, & Herman, 1999). The intervention model used in this experimental design study was built upon four characteristics of effective professional development indicated by the research: (a) development activities focus on subject content and active learning strategies; (b) activities are coherent with the curriculum teachers use; (c) data are used to track continuous improvement and define follow-up steps; and (d) teacher development involves school-based collaboration and teacher networking aimed toward sharing improvement ideas, practices, and strategies.
