Abstract Title: | Psychometric analysis of instrument measuring student reasoning skills* |
---|---|
Abstract: | This paper reports on the development and refinement of a two-tiered instrument aimed at measuring student reasoning in physics. Tier I focuses on assessing student conceptual understanding of physics through common introductory physics problems, or "screening" questions. Tier II then requires students to apply that conceptual understanding in situations that elicit intuitive, rather than formal, reasoning approaches, or "target" questions. The instrument was administered in algebra-based and calculus-based introductory physics courses during multiple semesters. Psychometric evidence was collected to establish reliability and item functioning. Future plans include using this instrument to assess instructional interventions aimed at developing students' reasoning skills and possibly modify it into a multiple-choice assessment for ease of administration and scoring. *This material is based upon work supported by the National Science Foundation under Grant Nos.
