Penelitian ini bertujuan untuk mendeskripsikan proses berpikir kritis mahasiswa dalam menentukan solusi dari persamaan diferensial. Penelitian ini menggunakan pendekatan kualitatif dengan jenis deskriptif-eksploratif. Subjek penelitian terdiri dari 3 mahasiswa Pendidikan Matematika Universitas Islam Malang. Instrumen utama dalam penelitian ini adalah peneliti sendiri. Selain itu juga digunakan soal tes sebagai instrument penelitian.  Soal tes disesuaikan dengan indikator kemampuan berpikir kritis IDEAS (Identify, Define, Enumerate, Analyze, Scrutinize). Soal tes terdiri dari 3 soal yang diberikan secara bertahap. Hasil soal tes selanjutnya dianalisis dan dilakukan wawancara kepada subjek penelitian untuk mengetahui proses berpikir kritis mahasiswa saat mengerjakan soal tes. Pada soal tes pertama, subjek penelitian belum mampu berpikir kritis dengan baik karena tidak dapat memenuhi indikator IDEAS. Oleh karena itu, mahasiswa diberikan scaffolding guna mengembangkan kemampuan berpikir kritis yang diberikan. Scaffolding diberikan dalam bentuk social scaffolding berupa penerapan model pembelajaran DD/CT (Deep Dialogue/ Critical Thinking) dalam perkuliahan persamaan diferensial. Pada soal tes kedua, kemampuan berpikir kritis mahasiswa mulai berkembang namun tetap belum memenuhi indikator IDEAS sehingga diberikan social scaffolding kembali berupa penerapan model pembelajaran DD/CT dipadukan dengan  model pembelajaran kooperatif tipe TS-TS (Two Stay-Two Stray). AbstractThis study aims to describe students' critical thinking processes in determining solutions to differential equations. This study uses a descriptive and explorative in a qualitative approach. The research subjects consisted of 3 Mathematics Education students at the University of Islam Malang. The main instrument in this study is the researchers themselves. In addition, test questions are also used as research instruments. Test questions are adapted to IDEAS (Identify, Define, Enumerate, Analyze, Scrutinize) critical thinking skills indicators. The test questions consist of 3 questions given in stages. The results of the test questions were then analyzed and interviewed to the subject of the study to find out the critical thinking process of students when working on test questions. In the first test question, the research subjects were not able to think critically well because they could not meet the IDEAS indicator. Therefore, students are given a scaffolding to develop the critical thinking skills provided. Scaffolding is given in the form of social scaffolding that is the application of the DD / CT (Deep Dialogue / Critical Thinking) learning model in lectures on differential equations. In the second test question, students' critical thinking skills began to develop but still did not meet the IDEAS indicator so that social scaffolding was again given in the form of the application of the DD / CT learning model combined with the TS-TS cooperative learning model (Two Stay-Two Stray).

This study aims to improve students' critical thinking skills through the application of Problem Based Instruction learning models. This research is a quasi experiment. The research subjects in this study were students of class VIIIA SMP Negeri 24 Bandar Lampung Academic Year 2017/2018 with a total of 32 students with a cluster random sampling technique. The required data is obtained through observation, documentation and tests using description questions. The collected data was analyzed by quantitative analysis techniques. The instruments used to collect data are tests of critical thinking skills. Data from the test results and observation sheets were analyzed quantitatively. The results showed that students 'critical thinking skills in the control class were 14.23% and included in the low category, while in the experimental class students' critical thinking abilities reached 87.5% or included in the high category. So, it can be said that the Problem Based Instruction learning model can improve students 'critical thinking skills, where students' critical thinking abilities increase from each cycle. So that the Problem Based Instruction learning model can be applied in learning both in mathematics and in other lessons.

Learning in 21st century requires an advance human mindset, especially critical thinking skills. Critical thinking skills improve the learning process to be more optimal in taking the core of the learning. However, data shows that the critical thinking skills of class XI IPA 2 students are still lacking because they have not been able to answer the analytical questions which is this is the important skills for the students. This paper aims to describe the use of discovery learning models to optimize students' critical thinking skills. The research method used is descriptive qualitative. The research subjects were 28 students of class XI IPA 2 in one of the senior high schools in Jakarta in the academic year 2021/2022 odd semester. Based on the study and data on each indicator, it was found that the use of discovery learning models was able to optimize students' critical thinking skills. Each step in the discovery learning model facilitates the achievement of indicators of critical thinking skills.

Thinking Ability

Mathematical Critical thinking is one of  mathematical abilities that must be obtained by students. Critical thinking is one of the high order thinking processes that can make concepts in student knowledge.  Students with critical thinking in mathematics learning mostly do rational activities such as interpreting information based on a particular theoretical framework, linking theory with practice, making claims and justifying it, utilizing data in support of argumentation, making relations or relationships between various ideas, asking questions, evaluating knowledge, predict, describe something, analyze, synthesize, and categorize. This study aims to analyze the effect of the Concept-Based Learning Model on the critical thingking mathematical abilities.The purpose of this research is to analyze the effect of Concept-Based Learning Model toward mathematics critical thinking ability. The method used in this research is quasi experiment by Randomize Control Group Post Test Only Design with cluster random sampling technique. Indicators of mathematics critical thinking skills measured in this study include providing simple explanations, building basic skills, concluding, making more explanations, and deciding an action. The results showed that the mathematics critical thinking ability of students in the experimental class for the five indicators that being analyze was higher than the ability of students in the control class. A fairly high difference in the indicator showed in give a simple explanation and concluding. and it means that the application of Concept-Based Learning Model significantly influences the  abilities  of students' mathematics critical thinking.
