Abstract

One of the abilities that students need to build when learning mathematics is problem solving ability, so that students can implement their mathematical knowledge. From the results of student tests in the previous year and exploring the problem, researchers found that the problem solving ability of students faced for Trigonometry material is analyzing problems, organizing ideas and solving problems. The purpose of this study is to describe how students' problem solving skills after experiencing learning with the Realistic Mathematics Education Approach (PMR) for Trigonometric Comparison material assisted by Geogebra. The research subjects were 31 grade X students in one of the private high schools in Bekasi city in 2024/2025. The data collection methods used were field notes, written tests, and interviews. The instrument validation technique used expert validation techniques, while to validate the data, triangulation techniques were used. The research results from the written test are as follows: (a) the most difficulties found for problems 1 and 2 were executing the plan to get a solution, and looking back at the solution process; (b) the most difficulties found for problem 3 were making a plan, executing the plan, and looking back at the solution process. From the interviews with five students, it was found that the most experienced difficulties were making a plan, carrying out the plan, and reviewing the solution process; (b) the most experienced difficulties for problem 3 were making a plan, carrying out the plan, and reviewing the solution process

Abstract

This article emphasizes the importance of the PMRI and ethnomathematics for meaningful learning. In addition, low mathematical literacy is caused by students’ difficulties in connecting concepts with real-life contexts, while the integration of cultural contexts such as the Ramayana Ballet into PMRI remains limited. This study aims to (1) design and implement Hypothetical Learning Trajectory (HLT) with PMRI and LKPD with Ramayana Ballet Prambanan context to develop mathematical literacy skills, (2) describe students' mathematical literacy skills after experiencing learning on circle topic with PMRI. The type of research used is design research with stages (1) designing HLT, (2) implementing HLT, and analyzing students' mathematical literacy skills after experiencing learning. The data analysis technique used was reducing data, presenting data, and drawing conclusions. The results obtained were: (1) Mathematics learning in class VIII Pinisi effectively brought up all the characteristics of PMRI; and (2) Mathematical literacy skills of students in class VIII Pinisi after learning with the PMRI showed that students still had difficulties in several aspects, namely: (a) problem 1, writing complete information (level knowing), (b) problem 2, writing complete information, applying strategies and operations for problem solving (level applying), and (c) problem 3, providing mathematical arguments and assessing problem solving strategies and alternative solutions (level reasoning).
