Abstract

Implementation of team assisted individualization instructional strategies supported by GeoGebra software to improve mathematical problem solving ability. Objectives: This quasi-experiment study aims to determine the effectiveness of Team Assisted Individualization (TAI) instructional strategies assisted by Geogebra graphical software to improve students’ mathematical problem solving abilities. Method: By cluster random sampling techniques, 66 students in grade VIII at SMPN 1 Wundulako were selected as sample. Data collection was carried out using pretest and posttest by applying test and non-test instrument. The data analysis was carried out with descriptive and inferential statistics. Findings: The Tukey test results showed that the significance value was 0.005 (α<0.05) with the average scores of the experimental and control classes 80.42 and 76.03. Conclusion: TAI strategy with graphical software is more effective in improving the mathematical problem solving ability than conventional learning. Keywords: Team assisted individualization, GeoGebra, mathematical problem solving ability DOI: http://dx.doi.org/10.23960/jpp.v9.i1.201903

Abstract

Mathematical problem-solving is a crucial competence that enables students to think critically and creatively in facing real-life challenges. However, mathematics learning often lacks meaningful connections to students’ cultural contexts. This study integrates local wisdom from the Tolaki Mekongga community as a culturally relevant approach to strengthen students’ understanding of mathematical concepts. The study aims to describe and analyze junior high school students’ mathematical problem-solving abilities through ethnomathematics-based problems derived from Tolaki Mekongga traditions. This research employed a descriptive qualitative design involving 32 eighth-grade students from SMP Negeri 2 Kolaka. Data were collected through problem-solving tests and interviews, then analyzed according to Polya’s four stages: understanding, planning, implementing, and reviewing the solution. The findings revealed that most students demonstrated moderate to high levels of problem-solving ability. High-ability students could relate mathematical concepts to local cultural contexts, while low-ability students struggled to interpret contextual information and apply appropriate strategies. The study concludes that incorporating problems based on local wisdom enhances students’ engagement and conceptual understanding. Integrating cultural contexts such as Tolaki Mekongga traditions can serve as an effective ethnomathematical approach for improving mathematical problem-solving skills and fostering culturally responsive mathematics learning.

Abstract

Penelitian ini bertujuan menjelaskan proses matematis siswa secara siklik dalam menyelesaikan masalah konsep perbandingan senilai berbasis open-ended pada konteks populer TikTok. Metode kualitatif deskriptif digunakan pada penelitian ini dengan mengambil 143 subjek, yang kemudian secara purposive dipilih 77 lembar kerja yang mampu menyelesaikan masalah dan dibagi menjadi 8 kelompok proses. Data dikumpulkan melalui tes dan wawancara diagnostik yang dianalisis menggunakan teknik flow model dengan memperhatikan tahapan mathematical modelling. Hasil penelitian menunjukkan ragam proses matematis siswa dalam menemukan solusi. Subjek memahami situasi nyata (real situation) untuk menentukan frame yang cocok dengan ukuran gambar. Berdasarkan informasi tersebut, subjek membangun asumsi dalam bentuk representasi verbal, numerik, simbol, dan visual (real world model). Representasi tersebut diasosiasikan dan dioperasikan mengikuti prinsip dan konsep matematika (perbandingan rasio, perbandingan skala sisi, perkalian silang, perkalian dengan skala, kelipatan, dan pola pengurangan berulang) (mathematical model) untuk menghasilkan solusi (mathematical result). Solusi yang diperoleh direfleksikan kembali ke real situation dengan memutuskan frame yang berbanding senilai dengan ukuran gambar. Konteks populer TikTok pada penelitian ini berhasil menjadi daya tarik budaya digital yang mengaktifkan keterampilan berpikir siswa serta menstimulasi tanggapan kreatif dalam pemecahan masalah.
