%X Penelitian ini bertujuan untuk menganalisis peningkatan kemampuan berpikir kritis matematis siswa (KBKM) yang memperoleh pembelajaran dengan model Problem-Based Learning (PBL) dan Discovery Learning (DL)  berdasarkan level Disposisi Matematis siswa (DMS), mendeskripsikan kecenderungan Kemampuan Berpikir Kritis Matematis berdasarkan level Disposisi Matematis siswa (DMS) dan menggambarkan karakteristik Disposisi Matematis siswa (DMS) yang dimiliki kelompok siswa level DMS (tinggi, sedang, rendah) dalam materi bangun datar segitiga dan segiempat. Metode dalam penelitian ini adalah mixed method dengan Stategi Embedded Konkuren. Dalam tahapan kuantitatif digunakan penelitian deskriptif dan kuasi eksperimen dengan jenis one group pretest-posttes design, one way anova dan desain faktorial 3 x 2. Dalam tahap kualitatif digunakan rancangan stategi embedded konkuren. Sampel dalam penelitian ini adalah siswa kelas VII SMP Negeri di Kota Cimahi berjumlah 72 siswa. Hasil penelitian: i) Terdapat perbedaan yang signifikan dalam peningkatan kemampuan berpikir kritis matematis antara siswa, ii) Tidak terdapat perbedaan signifikan dalam disposisi matematis siswa, iii) Terdapat perbedaaan peningkatan kemampuan berpikir kritis matematis siswa berdasarkan tingkat disposisi matematik siswa, iv) Disposisi matematis dan model pembelajaran (PBL dan DL) memiliki pengaruh yang signifikan terhadap peningkatan kemampuan berpikir kritis, v) Problem-Based Learning (PBL) memberikan pengaruh yang signifikan terhadap kemampuan berpikir kritis matematis, vi) Discovery Learning (PBL) memberikan pengaruh yang signifikan terhadap kemampuan berpikir kritis matematis, vii) model pembelajaran PBL dan DL  lebih efektif diterapkan pada siswa dengan KBKM kategori tinggi dan sedang, viii) Siswa disposisi tinggi dalam model PBL mampu menyimpulkan dan memberi alasan logis, siswa sedang memahami konsep namun kurang mendalam, sedangkan siswa rendah hanya mampu menghitung tanpa penjelasan yang kuat, ix) Siswa disposisi tinggi dalam model DL mampu mengidentifikasi masalah dan menyimpulkan dengan bukti kuat. Siswa sedang cukup logis namun belum menyeluruh, sedangkan siswa rendah memahami dasar masalah tapi kesulitan menyusun kesimpulan yang didukung bukti.  .	    Kata Kunci: Kemampuan berpikir kritis, disposisi matematis, Problem Based Learning, Discovery Learning, Visual Basic Application.    This study aims to analyze the improvement of students' mathematical critical thinking skills (KBKM) who received learning with the Problem-Based Learning (PBL) and Discovery Learning (DL) models based on students' Mathematical Disposition (DMS) levels, describe the tendency of Mathematical Critical Thinking Skills based on students' Mathematical Disposition (DMS) levels and describe the characteristics of students' Mathematical Disposition (DMS) owned by groups of students at DMS levels (high, medium, low) in the material of triangles and quadrilaterals. The method in this study is a mixed method with Concurrent Embedded Strategy. In the quantitative stage, descriptive and quasi-experimental research was used with one group pretest-posttest design, one way anova and 3 x 2 factorial design. In the qualitative stage, a concurrent embedded strategy design was used. The sample in this study was 72 students of grade VII of Public Junior High Schools in Cimahi City. The results of the study: i) There is a significant difference in the improvement of mathematical critical thinking skills between students, ii) There is no significant difference in students' mathematical disposition, iii) There is a difference in the improvement of students' mathematical critical thinking skills based on the level of students' mathematical disposition, iv) Mathematical disposition and learning models (PBL and DL) have a significant influence on the improvement of critical thinking skills, v) Problem-Based Learning (PBL) has a significant influence on mathematical critical thinking skills, vi) Discovery Learning (PBL) has a significant influence on mathematical critical thinking skills, vii) PBL and DL learning models are more effective when applied to students with high and medium KBKM categories, viii) High disposition students in the PBL model are able to conclude and provide logical reasons, medium students understand the concept but not deeply, while low students are only able to calculate without strong explanations, ix) High disposition students in the DL model are able to identify problems and conclude with strong evidence. Average students are quite logical but not yet thorough, while low students understand the basics of the problem but have difficulty drawing conclusions supported by evidence.   Keywords: Critical thinking skills, mathematical disposition, Problem-Based Learning, Discovery Learning, Visual Basic Application
