Populasinya adalah seluruh siswa SMP Swasta Ar-rahman Percut dan sampelnya adalah siswa kelas VIII  sebanyak 60 orang. Instrumen yang digunakan terdiri dari tes kemampuan berpikir kritis matematis dan skala kemandirian belajar. Data dianalisis dengan uji ANAVA dua jalur. Dari hasil analisis diperoleh: (1) peningkatan kemampuan berpikir kritis matematis siswa yang diberi pembelajaran berbasis masalah lebih tinggi daripada yang diberi pembelajaran langsung; (2) tidak terdapat interaksi antara  pembelajaran dengan kemampuan awal matematika terhadap peningkatan kemampuan berpikir kritis matematis; (3) peningkatan kemandirian belajar siswa yang diberi pembelajaran berbasis masalah lebih tinggi daripada yang diberi pembelajaran langsung (4) tidak terdapat interaksi antara pembelajaran dengan kemampuan awal matematika terhadap peningkatan kemandirian belajar.</p><p><strong>Kata Kunci</strong>:   Berpikir Kritis Matematis, Kemandirian Belajar</p><p> </p><p align="center"><strong>ABSTRACT</strong><strong></strong></p><p>The purposes of this research were to know: (1) The difference of improvement in mathematical critical thinking ability of students that given problem-based learning  with students that given direct learning; (2) The interaction between the model of learning with students’ mathematical previous knowledge toward the improvement in mathematical critical thinking ability; (3) The difference of improvement in self-regulated learning of students that given problem-based learning with students that given  direct learning; (4) The interaction between the model of learning with students’ mathematical previous knowledge toward the improvement in self-regulated learning. The population of this research is all students of SMP Swasta Ar-rahman Percut and the sample of this research is grade eight with taken sample two classes (experiment and control) with sample 60 students. The instrument of this research were: test of mathematical critical thinking and scale of self-regulated learning. Based of the results analysis, it showed that: (1) Improvement of the students’ ability in mathematical critical thinking that given problem-based learning was higher than the students’ ability that given direct learning; (2) There did not exist interaction between model of learning and students’ mathematical previous knowledge toward the improvement ability mathematical critical thinking; (3) Improvment  of the students’ self-regulated learning that given problem-based learning was higher than the students’ ability that given direct learning; (4) There did not exist interaction between model of learning and students’ mathematical previous knowledge toward the improvement self-regulated learning.</p></div><p><strong>Keywords</strong>:    Critical Thinking Mathematics, Self-Regulated Learning.</p>
