A domain of learning, understanding is an absolute prerequisite for improving cognitive abilities. Leveling the mental model of students is one way in which a teacher can review the extent to which students understand based on their respective levels. The purpose of this study was to describe the six degrees of student's mental models in understanding the concept of using the Pythagoras theorem in junior high school students. The method used in this study is a qualitative research method. The subjects in this study amounted to 61 students who were a combination of 30 students of class VIII A and 31 students of class VIII B. The two classes of subjects were taken so that the six levels of the mental model were founded. The sixty-one items test questions were given. Each of the representatives of mental models who found the criteria was selected, namely two students to be interviewed so that 12 students were interview respondents. To ensure the validity of the data, researchers analyzed the data in two ways, namely data source triangulation and method triangulation. The results of the study showed a description of each level of the student's mental model in understanding the concept of using the Pythagoras theorem. Suatudomain belajar, pemahaman merupakan prasyaratan mutlak untuk meningkatkankemampuankognitif. Pelevelan model mental siswa merupakan salah satu cara dimana seorang pengajar dapat meninjau sejauh manakah pemahaman siswa berdasarkan tingkatan masing – masing. Tujuan penelitian ini adalah untuk mendeskripsikan enam level model mental siswa dalam memahami konsep penggunaan teorema pythagoras pada siswa SMP. Metode yang digunakan dalam penelitian ini adalah metode penelitian kualitatif. Subjek dalam penelitian ini berjumlah 61 siswa yang merupakan gabungan dari 30 siswa kelas VIII A dan 31 siswa kelas VIII B. Dua kelas subjek tersebut diambil agar terpenuhi keenam level model mental. Keenam puluh satu subjek tersebut diberikan soal tes, kemudian dipilih masing – masing dari perwakilan model mental yang telah memenuhi kriteria yaitu 2 siswa untuk diwawancarai. Sehingga terdapat 12 siswa yang menjadi respondenwawancara. Untuk memastikan kevalidan data, peneliti menganalisis data dengan dua cara yaitu triangulasi sumber data dan triangulasi metode. Hasil penelitian menunjukkan deskripsi masing - masinglevel model mental siswa dalam memahami konsep penggunaan teorema pythagoras.

This article aims to determine the extent to which the ability to structure sense in the form of material binding a^2-b^2=(a-b)(a+b). This type of research is qualitative research. The subjects of this study were students of class VII-B MTs ASSALAM Bangilan, amounting to 25 students. However, only six subjects were analyzed based on the ability indicators of structure sense in terms of the same answer patterns. The research instrument consisted of test questions and interview guidelines. Data analysis techniques used in the model of Miles and Huberman include data reduction, data presentation, and concluding. The study results showed that in question number 1, 40% of students could sense structure, and 60% are less familiar with the sense of structure due to each deployment's completion, not using the form a^2-b^2=(a-b)(a+b). In question number 2, 32% of students can structure sense, and 68% are less familiar with the sense of structure due to a^2-b^2=(a-b)(a+b) sensitivity is still low, and the answer pattern describes each appointment. Whereas in question number 3, only 28% can structure sense, and 72% lack familiarity with structure sense because they cannot manipulate structures properly. In conclusion, the ability to structure sense to form a^2-b^2=(a-b)(a+b) students is still low. Artikel ini bertujuan untuk mengetahui sejauhmana kemampuan structure sense pada materi pemangakatan bentuk a^2-b^2=(a-b)(a+b). Jenis penelitian ini menggunakan penelitian kualitatif. Subyek penelitian ini adalah siswa kelas VII-B MTs ASSALAM Bangilan yang berjumlah 25 siswa, akan tetapi hanya diambil 6 subyek yang dianalisis berdasarkan indikator kemampuan structure sense ditinjau dari pola jawaban yang sama. Instrumen penelitian terdiri dari soal tes dan pedoman wawancara. Teknik analisis data menggunakan model Miles dan Huberman meliputi reduksi data, penyajian data dan penarikan kesimpulan. Hasil penelitian menunjukkan bahwa pada soal no. 1, 40% siswa memiliki kemampuan structure sense dan 60% kurang mengenal structure sense disebabkan dalam penyelsaiannya menjebarkan masing-masing pemangkatan, tidak menggunakan bentuk a^2-b^2=(a-b)(a+b). Pada soal no. 2, 32% siswa memiliki kemampuan structure sense dan 68% kurang mengenal structure sense disebabkan kepekaan struktur pemangkatan a^2-b^2=(a-b)(a+b) masih rendah, dan pola jawabannya menjabarkan masing-masing pemangkatan. Sedangkan pada soal no. 3 hanya 28% yang memiliki kemampuan structure sense dan 72% kurang mengenal structure sensedisebabkan tidak dapat memanipulasi struktur dengan tepat. Kesimpulannya kemampuan structure sense pemangakata bentuk a^2-b^2=(a-b)(a+b) siswa masih rendah.
