Nurul Hidayah — 2024-05-31

This study aims to determine students' abilities in understanding mathematical concepts when solving mathematics problems on the topic of common tangents of circles, as viewed through Pirie and Kieren's Theory. This research is a qualitative descriptive study. The subjects of this research are 36 students of class XI.6 at SMA N 2 Semarang, with three students selected from each category of low, medium, and high abilities. The data collection technique used was a test. Subjects were analyzed based on indicators from Pirie and Kieren, namely Primitive knowing, Image making, Image having, Property noticing, Formalizing, Observing, Structuring, and Inventising. The study results show that students with low conceptual understanding abilities only met the indicators of restating concepts and classifying objects according to their properties, thus, they remain at the Image Having layer. Students with medium conceptual understanding abilities have reached the indicators of using, utilizing, and selecting specific operational procedures, thus, they remain at the Observing layer. Meanwhile, students with high conceptual understanding abilities have met all the indicators of conceptual understanding abilities but are still at the Structuring layer.

Dliya Fitri Putri Setyawan — 2024-05-31

Students' abilities in mathematics are very necessary in learning mathematics. One way to determine the level of students' ability to solve mathematical problems is with the SOLO taxonomy. This taxonomy consists of five levels: Prestructural, Unistructural, Multistructural, Relational, and Extended Abstract. This research is descriptive qualitative research. The research subjects were taken from 3 students in class X-4 of SMA Negeri 1 Jombang, and the criteria were that students had high, medium, and low mathematics abilities. The data collection methods used were tests, interviews, documentation, and supporting instruments in the form of problem-solving tests, interview guides, and documentation. Time triangulation was carried out to check the validity of the research data. The results of research on mathematical problem-solving abilities based on the SOLO taxonomy for subjects with high mathematical abilities and subjects with moderate mathematical abilities show that the subjects are at the Extended Abstract level, which means that the subjects can prove the truth regarding the results obtained so that the results obtained are relevant so that the subjects can make hypotheses in the form of formulas, patterns, or rules for solving problems. Students can generalize or apply mathematical concepts involved in the problem to similar situations or problems. Subjects with low mathematical ability indicate that the subject is at the Multistructural level, which means the subject can describe the steps in solving the problem, but there are still calculation errors.
