Abstract

This research aims (1) to determine the steps for learning about the surface area of ​​a cone using the Problem Based Learning (PBL) approach and (2) to describe students' conceptual understanding abilities in the material regarding the surface area of ​​a cone after learning using the PBL approach. This research was conducted at Panca Marga State Middle School in April 2023. This research method is qualitative research. The subjects in this research were 20 class VIII students, and 2 students' work samples were taken. The data collection methods used were Student Worksheets (LKS), documentation, written tests and interviews. Data analysis includes data reduction, data presentation and drawing conclusions. The results of this research show that (1) Learning steps on cone surface area material using the PBL approach are effective in improving students' understanding abilities, namely (a) orienting students to the problem, (b) organizing students' learning, (c) guiding investigations individually and in groups, (d) developing and presenting the results of the work, (e) analyzing and evaluating the solution process, (2) Ability to understand the concepts of class VIII students after following learning with the PBL approach, namely for questions number 1 and 2, 20 students were able to achieve indicators 1-4 understanding concepts, namely presenting concepts as a form of representation, developing necessary and sufficient conditions, using, exploiting and selecting certain procedures, and classifying algorithm concepts for problem solving.

Abstract

The activity to discover the social role of the main character in the short story Hawa Panas by Silvester Petara Hurit was carried out using a qualitative method with dramatic techniques. This method directly explains the concrete actions carried out by the characters in the story. This activity integrates a sociological approach to literature and mathematical concepts to explain the social roles that appear in the story. The collaboration between the Indonesian Language and Literature Education study program and the Mathematics Education study program at the FKIP Larantuka Teacher Training and Technology Institute allows the application of mathematical concepts in understanding the story. In this short story, there are several social roles that can be found, namely: (1) building relationships between individuals to create strong social bonds, (2) being sensitive in responding to surrounding conditions and providing appropriate responses, (3) communicating appropriately to avoid misinterpretation, (4) using a cultural approach to respect prevailing social norms, and (5) showing compassion for others. This activity also provides a deeper understanding of the application of social concepts in everyday life through literary stories.

Abstract

Penelitian ini dilakukan untuk mengatasi kesulitan siswa dalam memahami konsep Teorema Pythagoras dengan mengembangkan Hypothetical Learning Trajectory (HLT) berbasis Problem Based Learning (PBL) dan mendeskripsikan kemampuan pemahaman konsep siswa. Jenis penelitian yang digunakan ialah penelitian desain dengan pendekatan kualitatif. Kegiatan penelitian berlangsung di SMPS Dharma Nusa, Desa Helanlangowuyo, Kecamatan Ile Boleng pada bulan Mei 2025, dengan subjek siswa kelas VIII. Data penelitian dikumpulkan melalui proses pembelajaran, Lembar Kerja Siswa (LKS), tes tertulis, wawancara, dokumentasi, dan catatan lapangan. Analisis data meliputi reduksi, penyajian, serta verifikasi atau penarikan kesimpulan. Hasil penelitian menunjukkan: (1) secara teoretis, lintasan belajar berbasis PBL dapat memfasilitasi penemuan konsep Teorema Pythagoras; (2) kemampuan pemahaman konsep siswa meningkat, di mana pada masalah 1, 19 dari 20 siswa mencapai indikator 1-4, sedangkan 1 siswa belum mencapai indikator 4; pada masalah 2, 18 siswa mencapai indikator 1-4, dan 2 siswa belum mencapai indikator 3-4.
