From National Movement to Local Action: The Status of Standards-Based Science Instruction in Middle School Classrooms.
Swanson, Christopher B.; Plank, Stephen B.; Hewes, Gina M.
This study explores the possibility of measuring a specific instructional strategy using statistical methods based on item response theory. It measures teachers' instructional practices using the same rigorous statistical techniques now applied to most large-scale assessments of student achievement. It specifically examines teachers' use of pedagogical techniques consistent with those espoused by the national standards-based reform movement in science. Data come from a nationally representative sample of public school eighth graders and their teachers from the 1996 National Assessment of Educational Progress. The paper describes: "The Standards Movement; "The Case of Science"; "Data on Teacher Instructional Practices"; "A Descriptive Portrait of Middle School Science Instruction"; "The Item-Response Theory (IRT) Approach--A Primer" (the basic data matrix, introduction to IRT parameters, and advantages of an IRT approach); and "IRT Analysis for Standards-Based Science Instruction" (a model-building strategy, stages in model-building, a generalized model of standards-based science instruction, and placing standards-based instruction in context). Results suggest there are many benefits to applying IRT models to instruction. The diagnostic information produced by the IRT analyses provided an empirical means to systematically identify practices that did not appear to align conceptually with the construct of standards-based instruction.
