Abstract

Students frequently encounter difficulties comprehending and applying the least common multiple (LCM) concepts due to traditional teaching methods lacking engagement and failing to incorporate relevant real-life contexts. Through the Indonesian Realistic Mathematics Education approach, students are expected to be able to solve the problems given related to the Least Common Multiple (LCM) topic and understand it more deeply. This research is design research with a validation study type that includes three main stages: preparing for the experiment, designing an experiment, and retrospective analysis. A literature review and needs analysis were conducted in the preparation stages to identify problems in learning this LCM topic. The design experiment stage involved using activity sheets, which were implemented into teaching and integrated the LCM concept utilizing the context of a calendar. This stage involved data collection through observation, questionnaire, documentation, and field notes. Retrospective analysis was conducted to evaluate the learning design and make revisions based on the evaluation result and feedback from students, teachers, peers, and lecturers. The result showed that using the context of the activity calendar in learning for LCM topics can enhance students’ understanding of the material and make the learning process more contextual and interesting.

Abstract

Kemampuan pemodelan matematika dan penalaran merupakan kompetensi kunci dalam literasi matematika PISA yang masih menjadi tantangan bagi siswa Indonesia. Penelitian ini bertujuan untuk menganalisis kemampuan pemodelan matematika dan penalaran siswa kelas VIII SMP Negeri 3 Gelumbang dalam menyelesaikan soal kontekstual PISA. Penelitian kualitatif deskriptif ini melibatkan 17 siswa yang dipilih berdasarkan variasi kemampuan matematika. Lima indikator pemodelan matematika Blum dan Kaiser digunakan sebagai kerangka analisis: structuring, mathematization, solving, interpreting, dan validating. Data dikumpulkan melalui tes tertulis menggunakan soal PISA. Analisis kualitatif dilakukan terhadap jawaban siswa pada soal-soal PISA yang dipilih, untuk mengidentifikasi strategi, kesulitan, dan pemahaman konsep yang dimiliki siswa. Hasil penelitian menunjukkan bahwa siswa menguasai dengan baik indikator structuring dan solving, namun mengalami kesulitan signifikan pada indikator interpreting dan validating. Pada aspek penalaran matematis, siswa menunjukkan kemampuan yang memadai dalam penalaran kuantitatif, tetapi mengalami kesulitan dalam penalaran spasial-temporal dan argumentasi logis. Kesulitan utama yang diidentifikasi meliputi ketidakmampuan menghubungkan hasil matematis dengan konteks masalah nyata, kurangnya kebiasaan melakukan validasi solusi, dan lemahnya kemampuan mengkonstruksi argumen matematis yang logis. Penelitian ini menyoroti pentingnya pengembangan kemampuan pemodelan matematika dan penalaran siswa dalam pembelajaran matematika saat ini.
