Abstract Title: Tapping into sophomores' understanding of classical mechanics: The Colorado Classical Mechanics/math methods Instrument (CCMI)
Abstract: Reliable and validated assessments of introductory physics have been instrumental in driving curricular and pedagogical reforms that lead to improved student learning, attitudes toward science, and self-efficacy. At CU Boulder, we are developing an open-ended conceptual instrument (the Colorado Classical Mechanics/math methods Instrument, CCMI) designed, among other purposes, to probe the effectiveness of instruction in middle-division classical mechanics. Questions on the CCMI focus on core concepts, methods, and tools taught in the first half of a two-semester classical mechanics sequence. In this paper, we describe the design and development of this instrument, its intended uses, and initial measurements made in student-centered classes at CU Boulder. We also outline the work necessary to validate the instrument, which has begun by soliciting feedback from both faculty at CU Boulder and other institutions (face validity) and will continue with student interviews (construct validity).
