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. Penelitian ini merupakan penelitian deskriptif. Subjek penelitian merupakan mahasiswa pendidikan kimia yang merupakan calon guru kimia. Instrumen yang digunakan dalam penelitian ini adalah tes keterampilan berpikir kritis dan kuisioner keterampilan berpikir kritis.

Implementation of Curriculum 2013 requires students to learn actively, independently, and critical thinking. Critical thinking is an activity through thinking about ideas related to concepts or problems. The efforts to improve critical thinking skills of learners can be done by using the appropriate learning model. One of the learning models that can be used to improve the ability of critical thinking is a problem-based learning model. This type of research is quasi experiment with randomized control-group pretest posttest design. The sample of this research choosed by used purposive sampling method. Class VIII6 as experimental class and class VIII4 as control class. Data of this research result are quantitative data of critical thinking ability. Data were analyzed by using t test. The results showed that the mean difference of posttest value with pretest value of critical thinking ability of experimental class learners is higher than control class. Hypothesis testing with t-test obtained tcalculate=2,94>ttable= 1,67, then H1 accepted. Based on these results the authors conclude that the implementation of problem-based learning model has a positive effect on the ability to think critically learners on the material additives and addictive substances.

Learning Guide

<p><em>The demands of the 2013 curriculum ideally are that learning is able to develop 4C skills, one of which is critical thinking and problem-solving skills (Critical-Thinking and Problem-Solving Skills), namely being able to think critically, laterally, and systematically, especially in the context of problem solving. In fact, students' critical thinking skills have not been maximally developed, especially in elementary schools. The learning process in elementary schools currently requires problem-based learning that requires students to actively carry out investigations in solving problems and the teacher acting as a facilitator or learning guide will be able to shape the ability of students to think critically. The purpose of this research is to describe the concept of Problem Based Learning (PBL), the concept of critical thinking ability, and the relationship between Problem Based Learning (PBL) and critical thinking ability. The results of the Problem Based Learning (PBL) model improve critical thinking ability.</em></p>

This study aims to inventory the type of necton, knowing the structure of the necton community and measuring the critical thinking skills of students of class VII.1 SMPN 1 Ujan Mas Kepahiang. The results showed that the necton obtained from the Taman Pintar pond amounted to 7 species and Pipi Putih Pond totaling 4 species. The necton species in the Taman Pintar pond  with the highest KP, KS, and FK values are tin head fish with KP, KR, and FK values respectively  0.102 idv / m2, 75.71% and 83%. While on the Pipi Putih Pond is local catfish species with the value of KP, KR, FK of 0.01 idv / m2, 39.29% and 25%. Then dominance index (H ') in the Taman Pintar pond is 0.61 and C' Pipi Putih pond  = 0.76. While the index of diversity of necton species in both ponds also belonged to very low category with H’ value of Taman Pintar Pond = 0.28 and H' of Pipi Putih pond  = 0.17. The result of Percentage Of Agreement test showed that  environment-based learning tools developed are included in the category highly feasible to be tested. Students’ critical thinking ability on the perpormance aspect shows 33 ,3 % percentage including critically critical criteria and 66,7 % including critical criteria. While Students’ critical thinking ability on the cognitive aspect shows four criteria, that are very critical as 26 %, crittical criteria 40 %, criteria critical enough 27 % and  criteria less 7 %

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.

The ability of students to think critically in mathematics is is still low. The lack of learning tools that are considered to facilitate students' mathematical critical thinking skills is one of the cause it. The purpose of this study was to develop a mathematics learning tool with a quality problem-based learning (PBM) model to facilitate students' mathematical critical thinking skills. The learning tools developed consisted of a syllabus, lesson plans (RPP) and student worksheets (LKPD) on the matrix material for class X SMK. This research was a development research using the Borg and Gall model. The development consists of six stages, namely: 1) research and data collection; 2) planning; 3) development of the initial product draft; 4) initial field trials; 5) revised trial results; and 6) dissemination and implementation. The subject of this research trial was the students of SMK Nurul Falah Pekanbaru. The instrument used was validation instrument for the syllabus, lesson plans, and student worksheet. Based on the results of the validation data analysis, it shows that the learning tools developed were very valid. The results of the validation of the syllabus were 85.11; the average RPP score was 86.02; and the average LKPD score was 86.40. The average student response questionnaire to the initial field trial was 85.93 with the very practical category. The learning device developed was valid and practical for use by class X SMK students.
