The essence of mathematics learning is the ability to solve math problems. Differences in ability, one of which is the suspect cognitive style. Based on the cause of the necessary mathematical problems of the students, cognitive style consists of a type of reflection and impulsive. So that the focus of this research is to analyze students' critical thinking skills in solving mathematical problems based on different types of reflective and impulsive cognitive style. Causal-comparative studies are needed to analyze the problem. The population of this study is composed of students of class VII SMPN 1 Susukan Cirebon. While the sample search uses the intentional sampling technique with the number of research samples 31 students. The technique of data collection using the Cognitive Style TMF test (correspondence familiar figures Test) and description Test (essay) Mathematics of critical thinking. The hypothesis test used is the t-test (T-test for independent samples). The results of the research show that the distribution of cognitive styles of students at SMPN 1 Susukan Cirebon, dominated by reflective-type cognitive style students (74% of students), while a small part of the students type of impulsive cognitive style (26% of students ). Critical thinking ability of reflective type students of cognitive style is better than the type of impulsive cognitive style students

Telah dilaksanakan penelitian tentang “Penerapan pendekatan STM (Sains Teknologi Masyarakat) pada konsep pencemaran lingkungan untuk meningkatkan hasil belajar, kemampuan berpikir kritis, dan sikap peduli lingkungan di SMA Negeri 4 Wira Bangsa Meulaboh”. Tujuan penelitian ini untuk mengetahui perbedaan hasil belajar, kemampuan berpikir kritis siswa pada materi pencemaran lingkungan yang dibelajarkan dengan pendekatan STM dan tanpa STM. Metode penelitian ini adalah metode eksperimental semu. Populasi dalam penelitian ini seluruh siswa kelas X SMA Negeri 4 Wira Bangsa Meulaboh, berjumlah 80 siswa yang berasal dari 3 kelas. Sampel pada penelitian ini adalah sebanyak 2 kelas yang ditentukan secara random sampling terdiri dari kelas eksperimen (dengan pendekatan STM) dan kelas kontrol (tanpa pendekatan STM). Instrumen penelitian ini menggunakan tes hasil belajar, tes kemampuan berpikir kritis. Pengujian hipotesis dilakukan dengan menggunakan uji-t Hasil pengujian hipotesis diperoleh thitung hasil belajar = 8,62, thitung kemampuan berpikir kritis = 11,15, dan thitung Karena harga thitung > ttabel maka Ha diterima dan harga thitung < ttabelmaka Ha ditolak artinya ada perbedaan peningkatan hasil belajar, kemampuan berpikir kritis siswa dengan pembelajaran STM dan tanpa pendekatan STM pada materi pencemaran lingkungan di SMA Negeri 4 Wira Bangsa Meulaboh. Kata Kunci: Pendekatan STM, dan Pencemaran Lingkungan A research entitled, "The application of the STM approach (Science Technology Society) on the concept of environmental pollution to improve learning outcomes, critical thinking skills, and attitudes of environmental care in SMA 4 Wira Bangsa Meulaboh " has been conducted. The purposes of this study were to find out differences in students’ learning outcomes and critical thinking skills on environmental pollution material by using STM approach. This research used quasi-experimental method. The population of this study was all of students class X of SMA Negeri 4 Wira Bangsa Meulaboh. There were 80 students from three classes. The samples were chosen randomly that consisted of two classes namely experimental class and control class. The instruments used were test for learning outcome and test for critical thinking skills. The data then analyzed by using t-test. The results of t-test for learning outcomes was 8.62, meanwhile, t-test of critical thinking skills was 11.15. Since t-count > t-table, thus Ha is accepted. If t-count < t- table then, Ha is rejected. It means there were some differences on students’ learning outcome and critical thinking skills after learning environmental pollution material by using STM approach and without using it.

This research aims to determine the application of teaching materials based on the skills of critical thinking in the Learning class XI SMA Negeri 1 Pasarwajo. This type of research is research quasi-experiment with design pretest-posttest group design. The treatment class consists of two classes, which are experimental classes taught with critical thinking skill-based teaching and control class taught with the teaching materials used by learners. The Data is analyzed by using the gain score normalized and continued with the Independent sample T-test at a level of significance of 5%. The results of this study showed a graph of increased experimental class critical thinking skills taught using critical thinking skill-based teaching materials are always higher than the control class taught with the teaching materials commonly used by learners in schools. Different test results (t-test) average Gain normalized critical thinking skills learn to demonstrate a significant difference between learning after receiving learning by using the teaching materials based on critical thinking skills compared to using teaching materials commonly used learners in schools with tvalue = 6, 322 is greater than this ttable = 1.671 at a = 0.05.

Electrolyte and nonelectrolyte based discovery modules are available learning is valid and practical, but has not been tested its effectiveness. Therefore the study aims to reveal the effectiveness of electrolyte and nonelectrolyte solution modules on students' learning outcomes and critical thinking skills. The module effectiveness test is done through quasi experimental research with Pretest-Posttest Control Group Design design. Research population of all students of class X MIPA SMAN 2 Bukittinggi. The sample was taken by purposive random cluster sampling technique.. The research instrument used in the form of learning result test and critical thinking skill assessment sheet. Techniques of data analysis of learning outcomes by using SPSS 16 software and critical thinking skills with percentage techniques. Based on the result of the research, it is found that the experimental class N-gain (0.76) is higher than control class (0.67). The data analysis technique showed that the experimental and control classes were normally distributed and had homogeneous variance, so the t-test was performed. From the result of t-test analysis obtained (sig) 0.006 &lt;0.05 which indicates that experiment class learning outcomes are significantly higher than control class. Based on the data analysis of students critical thinking skills, the average score of students' critical thinking skills is 87%. The research findings show that the use of electrolyte and nonelectrolyte based discovery modules learning effective on student learning outcomes and critical thinking skills at SMAN 2 Bukittinggi

The aim of this research is to know the effectivenessproblem based learning model (PBL) using student worksheet on learning outcomes and students’critical thinking skills on the teaching Reaction Rate. The population in this research was grade 11th of SMA Negeri 6 Medan. Classes sample was taken by random sampling, and two classes were selected as a sample. Those two classes will be taught with Problem Based Learning model, the difference is the first class will be used students worksheets and the other class is not. The instrumentto conduct this researchwas  by test and non-test. Based on parametric statistical test, the result of pretest, postest, and students’ critical thinking skills data from those two classes have a normal distribution and homogeny. Hypothesis was tested by using one tailed test with significant level ( ) =0,05. The data from hypothesis testing learning outcomes is tcal  ttable (3,101 1,669), means Hois rejected and Ha is accepted. Hypothesis testing result on students’ learning outcomes using student worksheets is higher than the non-using student worksheet. Critical thinking hypothesis test is tcal  ttable (4,754 1,669), means Hois rejected and Ha is accepted. Hypothesis testing result oncritical thinking using student worksheet is higher than the non-using student worksheet. Contribution of students’ critical thinking to the ups and downs of learning outcomes on the experiment class is 81,5%.
