Abstract

Mathematical representation is one of the higher-order thinking skills needed by students in analyzing physics cases as a form of proving the truth of understanding. Referring to the inconsistencies in the results of research on mathematical representation involving gender and the phenomenon of the high ability of female students in heterogeneous classes, it is suspected that there is a relationship between class type and mathematical representation. This study aims to analyze the increase in students' mathematical representation abilities in terms of gender differences in homogeneous classes. The research subjects consisted of class X high school students in Bantul, Indonesia, consisting of 26 boys and 27 girls. The research instrument was 5 physics questions that referred to indicators of mathematical representation. Data analysis to find out how the category of mathematical representation increases using the N-Gain index. The results of this study were (1) the improvement in the ability of the male students' mathematical representation in the medium category was superior to that of the female students, (2) the improvement in the ability to make mathematical expressions and use visual representations was better for the male students, and (3) the ability of the female students in terms of making image representations better than male students. This research implies that further research is needed to be related to the causes of students' misinterpretation in dealing with physics test.

Abstract

Free fall motion without initial velocity is a mechanical concept that can be analyzed using analytical, experimental, and computational methods. Free fall motion is difficult to analyze analytically if air friction is not neglected. The aim of this research is to explain computational free fall motion analysis procedures with air friction. Air friction disturbance in free fall motion is represented by the coefficient C which states the drag coefficient is time dependent. In this scientific study, the application used for computational analysis is IDE Spyder with various library support. With the help of this application, a significant difference in the output vmax and tmax is obtained between the two cases of free fall based on the interpretation of the graph that appears.
