Sažetak
Physics is an experimental science and measurements are central to the evaluation and formulation of ideas about the physical world. Assessing the reliability and validity of the measurements is an essential part of the measurement. However, physics education researchers have identified a number of student difficulties in understanding measurements and related uncertainty. Previous research has indicated that the graphical representations of data might help students in data processing and data comparison but this was not systematically explored. In this study, a paper and pencil test consisting of eight questions and six corresponding explanations was administered to 48 first-year students without laboratory experience and 53 senior years students at the University of Zagreb who were all prospective physics teachers. In half of the tests, a graphical representation of data was also provided. In addition, the eye movements of 30 senior years students were recorded while they were solving the same test. Overall, many students were unable to appropriately use the idea of measurement uncertainty. They exhibited the most difficulties while solving the test item that involved recognition of an outlier and its exclusion in the calculation of the mean value. Comparison of measurement results was also very difficult for many students. In contrast to these items, most students were able to write down the results of measurements including measurement uncertainty with the correct number of significant figures. As was expected, older students generally performed better than first-year students indicating that laboratory experience had a positive effect on student understanding of measurement uncertainty. Furthermore, graphical representation of measurement data helped students to perform better on test. Eye-tracking data confirmed this finding and provided further insight into student strategies in the data processing.
