Abstract

This community service aims to improve the mathematical thinking competence of teachers and students in facing mathematical Olympiads through two main activities: training for teachers and mathematical Olympiad coaching for students. Strengthening mathematical thinking competency is very important in preparing teachers and students to face the challenges of mathematics olympiads that demand high-level understanding, analysis, and problem solving. This activity was carried out by students of the Master's Program in Mathematics Education at Universitas Pendidikan Indonesia, with a focus on strengthening mathematical thinking strategies and developing skills to tackle mathematical Olympiad problems. The training for teachers was conducted online for 4.5 hours and attended by 530 participants from across Indonesia, while the student coaching took place at SMAN 1 Katapang for 5 hours with 19 participants. Quantitative evaluation through closed-ended questionnaires showed that the activity succeeded in suporting teachers’ mathematical thinking competencies and supporting students in solving olympiad-level problems. The collaboration between academics and educational practitioners in this activity is expected to make a significant contribution to improving the quality of mathematics education in Indonesia and strengthening students' competitiveness in mathematical Olympiads even on an international scale

Abstract

Kemampuan pemecahan masalah matematis siswa di Indonesia masih tergolong rendah, dengan kecemasan matematis diidentifikasi sebagai salah satu penyebab utamanya. Penelitian ini bertujuan untuk menggambarkan kemampuan pemecahan masalah matematika siswa berdasarkan tingkat kecemasan matematisnya, menggunakan pendekatan kualitatif dengan metode studi kasus. Partisipan terdiri dari 39 siswa kelas XI dari sebuah SMA di Kota Serang, Provinsi Banten, yang telah mempelajari barisan dan deret geometri. Data dikumpulkan melalui tes tulis untuk mengukur kemampuan pemecahan masalah matematika serta menggunakan teknik non-tes seperti kuesioner kecemasan matematis dan wawancara. Hasil penelitian menunjukkan bahwa siswa dengan tingkat kecemasan matematis rendah memenuhi semua indikator kemampuan pemecahan masalah matematis, siswa dengan tingkat kecemasan matematis sedang memenuhi tiga dari empat indikator, dan siswa dengan tingkat kecemasan matematis tinggi hanya memenuhi satu dari empat indikator tersebut. Oleh karena itu, guru dan siswa harus mempertimbangkan strategi yang tepat untuk mengurangi kecemasan matematis dalam metode pembelajaran guna meningkatkan kemampuan pemecahan masalah matematis siswa.The mathematical problem-solving ability (MPSA) of students in Indonesia is low, with mathematical anxiety identified as a contributing factor. This research sought to explore students' MPSA from the perspective of mathematical anxiety levels using a qualitative approach with a case study method. The participants included 39 grade XI students from a senior high school in Serang City, Banten Province, who had learned arithmetic and geometric sequences. Data collection included written tests for MPSA and non-test techniques such as mathematical anxiety questionnaire and interviews. The results reveal that students with low mathematical anxiety level fulfilled all the indicators of MPSA, students with moderate mathematical anxiety level fulfilled three of the four indicators of MPSA, and students with high mathematical anxiety level only fulfilled one of the four indicators of MPSA. Therefore, teachers and students should consider appropriate strategies to reduce mathematical anxiety in learning methods, aiming to enhance students’ mathematical problem-solving ability.
