Abstract


Mathematical literacy is an essential skill to master; however, the results of the PISA survey participated in by Indonesia indicate the low mathematical literacy skills of Indonesian students. To address the low level of students' literacy skills, it is necessary to identify the types of errors students make in solving mathematical literacy problems. This study aimed to analyze the errors made by junior high school students in solving mathematical literacy problems on linear function material. The research design used was a descriptive qualitative approach by selecting tree Grade VIII junior high school students from one of the schools in Bengkulu City as the subjects. The data were obtained using a mathematical literacy test instrument on linear function material given to the students. The description of errors was derived from analyzing the students’ work in solving problems within the process domain of mathematical literacy. Based on the analysis of students’ answers, several errors were found when they solved mathematical literacy problems in the processes of formulating, employing, and interpreting. The students’ errors in solving problems on quadratic function material included, at the formulate stage, failing to write the given and required information from the problem, and incompletely translating the problem into mathematical expressions. At the employ stage, students made errors in the solution steps, such as calculation mistakes and errors in algebraic operations. At the interpret stage, students made mistakes in formulating the solution into a proper conclusion.
