Effectiveness of a GUM-Compliant Course for Teaching Measurement in the Introductory Physics Laboratory
Pillay, Seshini; Buffler, Andy; Lubben, Fred; Allie, Saalih
European Journal of Physics, v29 n3 p647-659 May 2008
An evaluation of a course aimed at developing university students' understanding of the nature of scientific measurement and uncertainty is described. The course materials follow the framework for metrology as recommended in the "Guide to the Expression of Uncertainty in Measurement" (GUM). The evaluation of the course is based on responses to written questionnaires administered to a cohort of 76 first year physics students both pre- and post-instruction, which were interpreted in terms of "point" or "set" reasoning. These findings are compared with responses from a control group of 70 students who completed a similar laboratory course apart from the use of traditional approaches to measurement and data analysis. The results suggest that the GUM framework, together with the specific teaching strategies described, provides opportunities for more effective learning of measurement and uncertainty in the introductory laboratory.
