This research was conducted to identify and describe prospective teachers’ critical thinking skills profile as readiness to face the industrial revolution 4.0. This research was a descriptive research. Research subjects were  chemistry education students who are prospective chemistry teachers. The instruments used in this study were the Critical Thinking Ability Test and Critical Thinking Ability Questionnaire. The instrument used is valid and reliable. The results of the study showed that the critical thinking skills of prospective chemistry teacher students are still in sufficient criteria with average score 46,7. It was also found that students' critical thinking skills in 5th  semester  were better than those in semester 3rd and 1st with average score 57,46 and 41. This result was also supported by differences in student performance for each indicator of critical thinking skills. Chemistry students show better performance on indicators of building basic skills compared to other critical thinking skills indicators. Meanwhile, the indicators on building strategies and tactics of chemistry education students still showed  poor performance than other indicators. This needs to be improved immediately in order to prepare prospective chemistry teachers who are ready to compete in facing the industrial revolition 4.0. Improvements can be made by designing learning methods, teaching materials and evaluation tools that can improve students' critical thinking skills.Keywords: critical thinking skill, education 4.0., prospective chemistry teachers, revolutioanl industry 4.0ABSTRAK.Penelitian ini dilakukan untuk mengidentifikasi dan mendeskripsikan profil keterampilan berpikir kritis calon guru kimia sebagai kesiapan dalam menghadapi revolusi industri 4.0.

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.

 This study aims to determine students' critical thinking abilities in SMA Swasta Budisatrya Medan in ecosystem material. The ability to think critically is then analyzed based on indicators and compared with gender. The method used in this research is descriptive method with quantitative and qualitative approaches. The research sample is 69 students. The instrument of data collection is a test of critical thinking skills. Tests are given after students get material from the subject teacher. The technique used to process the scores obtained is to use a benchmark reference assessment technique (PAP). The results showed that students' thinking skills in ecosystem material were on average medium criteria, followed by low categories, then high and only 4 students who had critical thinking skills in the very high category. Overall, students' critical thinking skills are in the medium category. The highest critical thinking ability of students is on the indicators of strategy and tactics with moderate criteria, followed by conclusions, and provides a basic explanation. Furthermore, the lowest critical thinking ability of students is in the indicators of building basic skills and followed by making further explanations. The critical thinking ability of female students is higher than that of male students with an average score of 73 and is in the criteria of being moderate. While the average value of critical thinking skills of male students is only 64 and is in the low criteria. There is no significant difference between the critical thinking abilities of male and female students.

The problem that is often found in the field is that poorly trained students thinking critically because learning is still teacher-centered. The purpose of this study was to determine the effect of using inquiry-based handouts on students critical thinking abilities. The design of this study was experimental design with pretest and posttest group control design methods. It was by looking at the students ability to answer the pretest and posttest question sheets that contain critical thinking indicators such as analyzing, synthesizing, connecting, concluding, evaluating, and creating. The results of this study show that the students critical thinking skills for the group given the handout showed that they met good criteria, that is the average score above 75. Meanwhile, students critical thinking skills in the class or group of students who were not given handouts were still not more than 50. From the results of the study it can be concluded that the handouts
