Abstract


Abstract

The purpose of this study was to explore visualization preferences in solving questions of the absolute value of students. The research method used is descriptive qualitative with the type of case study research design. The data sources in this study were 2 students (case subjects), a math teacher, and the principal of SMA Santo Benediktus Pahauman for the 2019/2020 school year. The results showed that: (1) the ability to visualize the questions of students in solving the absolute value function questions was that students were able to determine the coordinate point correctly, but there were still weaknesses in the process, namely not giving a scale to the coordinates, while to describe the lines at the coordinates are correct; (2) the ability to manipulate or change images in solving problems with the absolute value function of the two students studied is that students can manipulate or change the images presented in absolute value questions, it's just that there is a deficiency where the scale on the graph is not given; (3) the ability to complete the pictures of students in solving absolute value questions. The two students studied were able to complete the picture on absolute value questions, but still did not give a scale to the image made.

Keywords: Preference Visualization, Solving of Absolute Value Function Questions
