Abstract
This study aims to evaluate representational competence in the concepts of momentum and impulse of high school students in distance learning during the Covid-19 pandemic. This research is also an attempt to find information whether there are differences in the competence of representation in different zoning schools. This research uses descriptive quantitative method. Sampling using cluster sampling technique, the number of samples was 517 high school students. The instrument used was in the form of multiple choice questions consisting of 3 items on the translation aspect, 3 items on the extrapolation aspect, 3 items on the interpolation aspect and 3 items on the interpretation aspect. The total number of questions is 12 items. Data were analyzed statistically to determine the percentage of representation competence and to determine differences in the competence of representations of the two schools. The results of the data analysis obtained showed that the representation competence of all students reached 44% in the medium category. Based on each aspect, the competency of the representation in the translation aspect shows 38% achievement in the medium category, the extraporation aspect is 38% in the medium category, the interpolation aspect is 58% in the medium category, and the interpretation aspect is 43% in the medium category. The statistical results show the value Asymp. Sig 0.000 < 0.05, which means that there is a difference in the representation competence of high school students between the urban zone and the district zone. This is reinforced by the results of the representation competence of high school students in urban zone schools which reached 67% in the high category. Meanwhile, the district zone reaches 34% in the medium category. This is because high school students who are in the urban zone are often trained in representation competence to be able to solve problems contained in physics concepts, one of which is momentum and impulse.
