    Effectiveness of a GUM-compliant course for teaching measurement in the introductory physics laboratory
    (European Physical Society, 2008) Pillay, Seshini; Buffler, Andy; Lubben, Fred; Allie, Saalih
    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.

    The evaluation of a research-based curriculum for teaching measurements in the first year physics laboratory
    (2006) Pillay, Seshini
    A new interactive introductory physics laboratory course, based on the ISO-recommended probabilistic interpretation of measurement and uncertainty has been developed. The course was piloted with first year physics students at the University of Cape Town in 2003. The present work evaluates this course.
