| Popis: | This research determined the students’ mathematical representations ability after learning used the Indonesian version of Realistic Mathematics Education (PMRI) trough Lesson Study for Learning Community (LSLC) on fractional operation. The subjects were seventh-grade students in SMP Negeri 18 Palembang. We used a descriptive method, which explains the stage of the research in detail. The data were collected through observation, written tests, and interviews. We used PMRI for material content and research context, and LSLC for the implementation of the learning process. We obtained that the students’ mathematical representations ability in answering fractional operation problems has reached the indicators. The research showed that students’ mathematical representation abilities have arisen, including solving problems involving mathematical expressions and load the problems situation based on data or representations given. The indicator that rarely appears is to draw geometric figures to clarify the problem and facilitate resolution. Giving real context through PMRI and collaborative learning process was to help students in bringing up mathematical indicators of representation. |
