The Model-Assisted Reasoning in Science (MARS) project seeks to promote model-centered instruction as a means of improving middle-school science education. As part of the evaluation of the sixth-grade curriculum, performance of MARS and non-MARS students was compared on a curriculum-neutral task. Fourteen students participated in structured interviews in which they experimented with a balance apparatus that provided three manipulable variables (two affected balance, one was a non-causal distract...

The Local Systemic Change initiative of the National Science Foundation supports projects focusing primarily on teacher enhancement through extensive professional development and the use of standards-based curriculum materials. The underlying rationale is that the effective use of such materials will ultimately result in enhanced student learning. However, the research base regarding the impact of these efforts on student learning is rather lean. This paper describes the results of a curriculum-...

The Model-based Analysis and Reasoning in Science (MARS) project is involved in developing model-centered curriculum modules for middle-school science. MARS instruction focuses on a variety of physical, pictorial, and symbolic representations of theoretical entities, providing tangible objects that students can use to think and talk about abstract concepts and links between concepts. This article examines the impact of the mass unit, the third unit of a sixth-grade curriculum module, implemented...

The Model-Assisted Reasoning in Science (MARS) project created a model-centered, computer-supported sixth-grade science curriculum organized around the theme balance of forces. To help monitor effectiveness during implementation in a public middle school, individual student interviews were conducted after each of the curriculum's three sections. In each interview, students were asked to explain why a helium balloon floats up. This article describes an analysis of student responses to the balloon...

Scientists and researchers in many disciplines frequently resort to modeling and model–based reasoning to concretize abstract ideas, to simplify and clarify complex phenomena, to predict trends, and to explain mechanisms and processes. National projects working to reform science education explicitly recommend the development of an appreciation for the centrality of models in the teaching and learning of science. This article describes a model–centered, computer–supported, semester–long science c...
