Abstract

This study aims to develop teaching methods that are effective, supportive, and efficient in enhancing students' understanding of mathematical concepts. The research followed the ADDIE development model, which consists of five phases: analysis, design, development, implementation, and evaluation. The study was conducted in response to students' difficulties in understanding trigonometric concepts and recent advancements in educational media identified by researchers. The feasibility and usability of the instructional tool was assessed by both teachers and students. Its validity was evaluated by involving media and content experts. A descriptive analysis was then performed on data collected through observations and interviews conducted throughout the research process. The results of the validity assessment showed scores of 89.29% from content experts and 80.58% from media experts, indicating that the instructional tool is highly suitable for classroom use. The evaluation form revealed scores of 90% from teachers and 78.72% from students, suggesting that the tool is considered very practical. Furthermore, an analysis of student performance demonstrated that Kipas MATHIC effectively enhances students’ understanding of trigonometric concepts.

Abstract

Walaupun telah banyak penelitian yang membahas kemampuan literasi matematika dalam menyelesaikan soal-soal PISA, konten uncertainty and data masih jarang dijadikan fokus utama. Penelitian ini bertujuan mengisi kekosongan tersebut dengan menganalisis secara mendalam terhadap pola berpikir serta strategi yang digunakan oleh siswa dalam mengerjakan soal-soal PISA yang berfokus pada konten uncertainty and data. Pendekatan penelitian yang digunakan adalah kualitatif deskriptif, dengan melibatkan tiga orang siswa sekolah menengah atas di Kota Palembang yang dipilih melalui teknik purposive sampling berdasarkan variasi tingkat kemampuan matematika. Data dikumpulkan melalui tes tertulis dan wawancara mendalam, kemudian dianalisis dengan mengaju pada tiga indikator literasi matematika dari OECD, yaitu formulate, employ, dan interpret. Hasil analisis menunjukkan bahwa siswa yang memiliki kemampuan matematika tinggi umumnya mampu memenuhi hampir semua indikator tersebut. Di sisi lain, siswa dengan tingkat kemampuan sedang umumnya hanya dapat memenuhi dua indikator, sementara siswa dengan kemampuan rendah tidak menunjukkan pencapaian berarti pada indikator manapun. Indikator formulate tampak sebagai aspek yang paling menantang bagi sebagian besar peserta didik. Temuan ini menegaskan pentingnya penguatan kemampuan literasi matematis, khususnya dalam merumuskan masalah dari konteks nyata, guna meningkatkan kualitas pembelajaran matematika di sekolah.
