Abstract

Penelitian kualitatif deskriptif ini bertujuan untuk mendeskripsikan kemampuan kognitif siswa SMP berkemampuan matematika tinggi dalam menyelesaikan soal tes pemahaman luas bangun datar gabungan berdasarkan domain TIMSS, yang meliputi pengetahuan konsep, penerapan konsep, dan penalaran konsep. Subjek penelitian terdiri dari dua siswa kelas VIII SMP berkemampuan matematika tinggi. Instrumen utama adalah peneliti sendiri, dibantu  pedoman wawancara, dokumen dan Tes Kemampuan Matematika yang berisi soal-soal mengacu pada soal TIMSS tentang luas gabungan. Data yang diperoleh dari subjek penelitian dianalisis menggunakan domain kognitif TIMSS pada ranah pengetahuan, penerapan, dan penalaran konsep. Hasil penelitian mengungkapkan bahwa kedua subjek penelitian memiliki kemampuan kognitif dengan predikat yang berbeda, yaitu predikat sangat baik dan baik. Subjek dengan predikat kemampuan kognitif sangat baik mampu mengolah informasi, merencana, menyelesaikan dan secara konsisten memahami luas gabungan dapat disusun dari bervariasi kombinasi luas bangun datar.  Subjek dengan predikat kemampuan kognitif baik mampu mengolah informasi, merencana, dan menyelesaikan permasalahan, namun masih belum memiliki pemahaman yang kuat tentang variasi-variasi kombinasi luas bangun datar penyusun luas gabungan. Hasil ini memberikan gambaran adanya perbedaan kemampuan kognitif  siswa, meskipun sama-sama berada pada kemampuan matematika tinggi. This descriptive qualitative research aims to describe the cognitive abilities of highly mathematics-capable junior high school students in completing the combined shapes area comprehension test based on the TIMSS domain, which includes knowing, applying, and reasoning. The research subjects consisted of two students in grade VIII junior high school with high mathematics ability.data collection is done online via Whatsapp by sending test instruments in PDF format. The main instruments are the researchers themselves, assisted by interview guidelines, documents and Math Ability Tests containing questions referring to the TIMSS question about the combined area. Data obtained from the study subjects were analyzed using the cognitive domain TIMSS in the realm of knowing, applying, and reasoning of concepts. The results revealed that both research subjects had cognitive abilities with different predicates, namely excellent and good predicates. Subjects with excellent cognitive ability predicates are able to process information, plan, complete and consistently understand the combined area can be composed of varied combinations of shapes areas.  Subjects with good cognitive ability predicates are able to process information, plan, and solve problems, but still do not have a strong understanding of the variations of the combination of shapes area combined constituents. These results give an idea of the differences in students' cognitive abilities, although they are both in high math ability.
