Abstract

This study aims to analyze the mathematical problem-solving abilities of seventh-grade students at SMP Kristen Palla on the topic of algebraic expressions using the Problem Based Learning (PBL) model. This research employed a qualitative descriptive approach involving 20 student participants. Data were collected through problem-solving tests and interviews based on Polya's problem-solving steps: understanding the problem, devising a plan, carrying out the plan, and reviewing the result. Data analysis techniques using the Miles & Huberman model, namely; data reduction, data presentation, and drawing conclusions. The results showed that 10 students (50%) demonstrated high problem-solving abilities and achieved mastery, 6 students (30%) were in the medium category, and 4 students (20%) were in the low category. Based on the minimum mastery criterion (KKM) set at 75, 10 students (50%) met the standard, while the other 10 (50%) did not. The PBL model effectively supports students in developing critical thinking and problem-solving skills, making learning more meaningful and contextual. This study is expected to serve as a reference for teachers in implementing effective instructional strategies to enhance students' mathematical problem-solving abilities

Abstract

This study aims to identify and describe the mathematical elements found in the traditional Sumba house in Weelonda Village and their connection to the cultural meanings held by the Sumba people. The study employs a qualitative approach using an ethnographic method. Mr. Aste Bili served as the informant, providing knowledge about the traditional Sumba house, while the research objects were the mathematical elements present in the structure. Data were collected through observation, interviews, and documentation, and subsequently analyzed descriptively. The results indicate that the traditional Sumba house embodies various ethnomathematical concepts related to activities such as counting, measuring, determining direction and location, and designing and constructing. These mathematical concepts are evident in the determination of dimensions and proportions, the spatial layout, and the building's form and structure. These mathematical elements serve not only practical functions during construction but are also linked to the values, symbols, and way of life of the Sumba community. Thus, the traditional Sumba house demonstrates that mathematical practices evolve in integration with the local community's knowledge and culture
