Abstract
This research was a descriptive case study. The purpose of this research was to describe the student’s ability to interpret the kinematics graph. The subjects of the study were 347 students of class XI science in the even semester of 2018/2019 in Luwu Raya, South Sulawesi Province, Indonesia. The research data were obtained from multiple-choice test results using instruments adapted from Test of Understanding Graph – Kinematics 2.6 and the results of in-depth interviews to find out the reasons learners choose answers and casual factors. The results of the study based on descriptive data analysis were 90 students or 25.94% in the low category, and 257 students or 74.06% were in the very low category. These results indicate the ability to interpret the graphs of students were still low, with the average achievement in answering questions on each of the highest indicators was 20.99 % on indicators identifying graphs based on the description. While the lowest average achievement was11.91%, which is the indicator to identify the graph that has a different variable. Base on the qualitative data analysis, the results are students had difficulties in solving the test, as follows: a) the difficulty in distinguishing symbol of the variables on the graph, b) the difficulty in determining the formula for solving test in graphical form, c) to determine when the curve on the graph v-t decreases then the object will move with speed slowed. The factors causing these difficulties are because students did not understand deeply about how to read graphs, how to solve test in graphical form, and did not understand the formula used to solve the test.
Highlights
Education is a whole learning experience that occurred in all environments and lasted forever
The lowest score was 0, while the average score achieved was 3.45. These results indicate that the ability to interpret the kinematics graphs of students was still deficient
The results of this study show that students’ ability to interpret the kinematics graph was in the shallow category
Summary
Education is a whole learning experience that occurred in all environments and lasted forever. The 2013 national curriculum in Indonesian (C-13), which applied in all levels of school, is a government effort to equip students in terms of scientific knowledge, skills, and attitudes in the earlier stage. This C-13 operationalized by applying scientific approaches to every learning activity in school (Rumahlatu et al, 2016). Through this approach, students are expected to be able to carry out scientific activities as a scientist does.
