Spiral Physics is a research based introductory physics curriculum developed at Monroe Community College. There are several important features of this curriculum. It  integrates text and workbook activities in a modular fashion, and arranges topics so that students receive repeated exposure to concepts with increased complexity. It makes use of alternative problem types, including goal-less problem statements, ranking tasks, and critical analysis tasks. It restricts the equation set available for student use and is designed to facilitate active learning. Spiral Physics is available for both the algebra-based and calculus-based introductory courses. Assessment of Spiral Physics via the FCI, MBT, and MPEX compare favorably with the best results reported in the literature.
