Modeling Instruction

Modeling Instruction is a research-based pedagogical approach for STEM education, particularly prominent in physics and chemistry. It emphasizes the construction and application of conceptual models by students to describe, explain, and predict scientific phenomena. Developed primarily at Arizona State University, the method shifts the classroom from passive reception to active, collaborative sense-making, positioning the teacher as a facilitator rather than a sole source of knowledge.

Overview

The approach was created in the early 1990s by David Hestenes, a theoretical physicist at Arizona State University, alongside educator Malcolm Wells. Its development was a direct response to recognized shortcomings in traditional science teaching, as highlighted by assessments like the Force Concept Inventory. The methodology is centrally administered by the American Modeling Teachers Association, which oversees curriculum development and teacher training. The core cycle involves model development, deployment, and refinement, making it a cornerstone of reformed pedagogical practices in institutions like the University of Chicago and many public school districts across the United States.

Theoretical foundations

Modeling Instruction is grounded in constructivism, particularly the theories of David Ausubel and Jean Piaget, which posit that learners actively build knowledge. It draws heavily on the conceptual change model of science education, challenging and revising student preconceptions. The framework is also informed by the work of Lillian McDermott and the Physics Education Research group at the University of Washington, which emphasizes identifying and addressing specific student difficulties. Philosophically, it aligns with a model-centered view of science itself, reminiscent of ideas from Thomas Kuhn regarding paradigm shifts and the nature of scientific theory.

Classroom implementation

A typical unit begins with a paradigm lab, such as a motion experiment using Vernier sensors, where students collect data to initially develop a model. Students then work in collaborative groups at whiteboards to represent their ideas, engaging in structured discourse often guided by Socratic questioning from the instructor. The curriculum employs specific representational tools like system schemas, energy bar charts, and motion maps, which are standardized across the community. Tools like the Open Source Physics library and software such as Tracker Video Analysis are frequently integrated. This implementation shares pedagogical similarities with, but is distinct from, approaches like Process Oriented Guided Inquiry Learning and the Interactive Lecture Demonstration format.

Research and efficacy

Multiple peer-reviewed studies, often published in journals like the American Journal of Physics and the Journal of Chemical Education, have demonstrated its effectiveness. Gains on standardized concept inventories, such as the Force Concept Inventory and the Mechanics Baseline Test, consistently show significant improvement over traditional instruction. Research from institutions like Florida International University and University of Maine has also shown positive impacts on student problem-solving abilities and attitudes toward science. The approach has received endorsement and funding from major organizations, including the National Science Foundation and the U.S. Department of Education.

Professional development

Teachers typically engage in intensive, multi-week summer workshops offered at sites nationwide, often hosted by universities like University of Arkansas or California State University, Fullerton. These workshops are led by experienced Modeling instructors certified by the American Modeling Teachers Association. The training immerses teachers in the student experience, having them complete entire instructional units while also focusing on pedagogical content knowledge. Follow-up support is provided through annual conferences, online forums, and continuing education credits, creating a sustained professional learning community. This development model has been recognized by organizations like the Albert Einstein Distinguished Educator Fellowship program.
