Abstract

The research was conducted with an aim of enhancing students' mathematical problem-solving skills of seventh grade students of MTs Negeri 1Yogyakarta using an approach of Indonesian Realistic Mathematics Education (PMRI). The subject of this research was the students of class VII-A of MTs Negeri Yogyakarta 1, which totaled 37 students. Type of the research was collaborative and participatory action research between mathematics teachers and the researcher. The data of the study were obtained through observations, interviews with teachers and students, questionnaires, tests of problem solving skills, field notes, and documentation. Based on research results, it was concluded that the mathematics teaching using PMRI approach in accordance with its characteristics of contextual, using mathematical models, using students’ production and construction, interactive, and linkages’ existence could enhance students' mathematical problem-solving abilities. This was indicated by: (1) the average score of the test on students' problem solving skills increased from 54.32 (sufficient criteria) in the pretest to be 61.97 (good criteria) in the first cycle and 72.97 (good criteria) on the second cycle and also all students had met the KKM standards set by the school; (2) the percentage of the average score of each step of students' problem-solving skills increased in the term of the ability to identify problems in the pretest of 69.0% (high qualification) increased to 76.93% (very high qualification) in the first cycle and on the second cycle increased to 84.87% (very high qualification). The ability to plan the completion in the pretest was 40.40% (adequate qualification) increased to 50.55% (high qualification) on the first cycle and on the second cycle increased to 65.4% (high qualification). The ability to resolve problems on the pretest of 64.45% (high qualification) increased to 69.18% (high qualification) on the first cycle and on the second cycle increased to 76.75% (very high qualification). The ability to re-evaluate the settlement amounted to 40.6% (sufficient qualification) in the pretest increased to 50.8% (high qualification) on the first cycle and on the second cycle increased to 67.4% (very high qualification); and (3) Based on questionnaire responses, students responded positively to the teaching through PMRI approach. This was supported by data from interviews with students revealing that the students liked the teaching of mathematics through PMRI approach because it was so much easier for students to use PMRI in learning mathematics. Keywords : PMRI, problem solving
