The ability to think critically in mathematics, especially high-level mathematical critical thinking, is needed by students so that students are able to face changing circumstances or challenges that exist in life that is always developing. Graded response models (GRM) are used in order to display the estimated item parameters and students' abilities. This research is a descriptive study with a qualitative approach. Subjects in this study using SMA Simpang Tiga in terms of their mathematical critical thinking skills. Subjects were taken using a mathematical critical thinking ability test, then processed through Microsoft Excel to obtain a Graded Response Models (GRM) graph.Based on data analysis Students can be categorized as highly skilled, in general students can determine the concept of the problem correctly, are able to formulate problems in solving problems, are able to provide reasons and arguments clearly, but students are less able to evaluate problems in solving problems. Students who are categorized as having moderate ability, students can determine the concept of the problem correctly, are able to formulate problems, but students are less clear in providing reasons and arguments clearly, and are less able to evaluate the problems contained in solving problems. Students who are categorized as low, students are able to determine the concept correctly, but students are less able to formulate problems, and students are unable to provide clear reasons.

Tujuan penelitian ini adalah untuk mengetahui apakah penerapan model discovery learning berbantuan software maple dapat meningkatkan kemampuan pemahaman matematik mahasiswa?. Penelitian ini merupakan penelitian eksperimen yang terdiri dari kelas eksperimen dan kelas kontrol. Kelas eksperimen dengan desain penelitian pretest-postes group . Populasi penelitian ini adalah seluruh mahasiswa semester II Fakultas Teknik Informatika Universitas Jabal Ghafur dengan sampel kelas B sebagai kelas eksperimen dan kelas D sebagai kelas kontrol yang masing-masing berjumlah 25 mahasiswa. Instrumen yang digunakan untuk mengumpulkan data penelitian berupa tes kemampuan pemahaman matematis. Uji statistik yang digunakan adalah uji-t untuk menganalisis data peningkatan kemampuan pemahaman matematis. Hasil analisis data diperoleh N-Gain kemampuan pemahaman matematis dengan nilai t = 1,046 dan Sig. (2-tailed) = 0,048 dan Sig. (1- tailed )= 0,024 sehingga nilai Sig. (1- tailed ) < taraf Signifikansi ( alpha =0,05). Hal ini menunjukkan bahwa peningkatan kemampuan pemahaman matematis mahasiswa yang menggunakan model discovery learning berbantuan software maple lebih baik daripada mahasiswa yang memperoleh pembelajaran konvensional. Abstract The purpose of this study was to determine wether the application of discovery learning models assisted by maple software can improve the students mathematical understanding abilities? This research is an experimental study consisting class and the control class. Experimental class with the pretest – post test group research design. The population of this research is all of the second semest er students 0f The Informatics Engineering Faculty of The Jabal Ghafur University with a sample of class B as an experimental class and class D as a control class, each numbering 25 students. The instrument use to collect research data is a mathematical understanding ability test. The statistical test used is the t-test to analyze the data on the improvement of mathemathical understanding abilities. The result of data analysis obtained N-Gain mathematical understanding ability with the value of t=1,046 and sig. (2-tailed)=0,048 and sig.(1-ta iled)=0,024 so The Value of sig. ( 1-tailed) < significance level (alpha = 0,05). This shows that the improvement of students mathematical understanding abilities using the discovery learning model assisted by maple software is better than students who obtain conventional.
