This study investigates undergraduate students’ ability to use the ideas of measurement and uncertainty to process and compare experimental data. These ideas include not only knowing what it means to use an instrument to take a measurement, but also being able to apply that knowledge, including the ideas that make up uncertainty analysis, to every aspect of an experiment. A physics laboratory course for the Energy Systems Engineering programme at Uppsala University has been designed to focus on teaching students the ideas of measurement and the associated laboratory skills. In the reported study, we use an open-ended survey to investigate students’ ideas about data processing and data comparison before and after this laboratory course. The results show that several students, even after the course, are still unable to appropriately use the ideas of uncertainty. This suggests that these ideas must be continuously revisited and explored as a fundamental part of all undergraduate laboratory experiences.
