Abstract Title: Methodological Development of a New Coding Scheme for an Established Assessment on Measurement Uncertainty in Laboratory Courses
Abstract: There is a need for research-based assessments in laboratory courses, both to improve such courses and to understand the unique learning that occurs in laboratory settings. In particular, a conceptual understanding of measurement uncertainty is a common learning goal in introductory laboratory courses. The Physics Measurement Questionnaire (PMQ) is an open-response assessment for measuring student understanding of measurement uncertainty. The PMQ was developed for use at the University of Cape Town, South Africa, and includes a coding scheme for analyzing responses from that institution. This original coding scheme needed to be modified for our different national and institutional context: the large introductory laboratory course at the University of Colorado Boulder, USA. Here, we document our process to develop a new coding scheme for the PMQ, and describe the resulting codebook. We also present preliminary results using the new scheme, from both before and after the course was transformed.
