Hasil penelitian menunjukkan bahwa subjek mampu menunjukkan kemampuan berpikir kritis yang tinggi. Hal ini ditunjukkan dengan terpenuhinya seluruh indikator kemampuan berpikir kritis dalam memecahkan masalah matematika yaitu menggunakan penalaran pada tahap memahami masalah, menganalisis keterkaitan masing-masing bagian dari keseluruhan untuk menghasilkan sistem yang kompleks pada tahap membuat perencanaan, menganalisis dan mengevaluasi fakta-fakta pada tahap melaksanakan perencanaan, dan menarik kesimpulan berdasarkan hasil analisis pada tahap memeriksa kembali. Walaupun ketiga subjek memenuhi keseluruhan indikator berpikir kritis, namun masing-masing subjek menunjukkan proses pemecahan masalah yang berbeda. Masalah open-ended dapat dipertimbangkan dalam melatihkan kemampuan berpikir kritis sekaligus mengakomodasi berbagai tingkatan akademik mahasiswa.AbstractCritical thinking is an ability that can be learned and trained to be able to solve problems effectively. This study aims to describe students' critical thinking skills in solving calculus problems. This type of study was descriptive qualitative research. The subjects were three undergraduate students of the IKIP Budi Utomo Malang Mathematics Education with high mathematical abilities. The research instruments were calculus problem solving questions and interview guidelines. The instruments used to explore students' critical thinking skills in solving problems. The results showed that subjects were able to demonstrate high critical thinking skills. This is indicated by the fulfillment of all indicators of critical thinking skills in solving mathematical problems, namely using reasoning at the stage of understanding the problem, analyzing the relationship of each part of the whole to produce a complex system at the stage of devising a plan, analyzing and evaluating the facts at the stage of carrying out the plan, and draw conclusions based on the results of the analysis at the stage of looking back. Although all three subjects fulfill all indicators of critical thinking skills, each subject shows a different problem solving process. Open ended problems can be considered to develop critical thinking skills while accommodating various academic levels of students.

Critical thinking skills is a very important aspect that students must have in learning chemistry, especially in solving problems that require deeper alternative solutions. This research aims to analyze the relationship of critical thinking on student learning outcomes on salt hydrolysis material. In this research, there were 48 students sampled, the technique used for sampling was purposive sampling. For data analysis in this research using correlation and regression tests with a probability value of 0.05. From the results of the linearity and correlation tests found that students 'critical thinking skills have a relationship with student learning outcomes on salt hydrolysis material by 0.599 and the regression results also show the same thing that there is a significant relationship between students' critical thinking skills with learning outcomes on salt hydrolysis material that is seen from the comparison of the significance value (0,000) with a probability value (0.05), (0,000 <0.05) means that there is a positive relationship between critical thinking skills with student learning outcomes on salt hydrolysis material in SMAN 1 Kampar. The contribution or contribution of students' critical thinking skills to learning outcomes in the hydrolysis material is 35.9% while the remaining 64.1% is influenced by other factors. The higher the level of critical thinking skills of students, the greater the significant functional relationship to learning outcomes, and also the greater contribution / contribution of critical thinking skills to student learning outcomes.Keywords : Critical thinking skills, learning outcomes, correlation and regression analysis, salt hydrolysis

This study aimed to investigate the relationships between teachers' knowledge, beliefs and activities about critical thinking. . The study followed the descriptive approach. This research was based on a questionnaire designed to investigate English teachers' points of view about critical thinking for primary and secondary schools in Qasabet Al Mafraq which is a city in the north of Jordan The population of the study is 280 female and male teachers distributed through 160 primary and secondary school. The study sample was randomly selected and it represents 46% of all English teachers in Qasbet Al Mafraq. They are 40 male and 88 female teachers during the second semester 2018/2019. The results of the study indicate that most of the teachers know the higher and lower –order of critical thinking skills. Also, they are inclined to use the critical thinking strategy to achieve certain outcomes in the curriculum. According to the teachers' beliefs, they think critical thinking is an important and effective strategy for problem solving and decision making. On one hand, there is a positive correlation between teacher's knowledge, teachers' belief and critical thinking activitie such as role- playing, asking questions, problem- solving, conceptual maps, debate and game playing. But on the other hand, there are no statistically significant differences at (a= 0.05) due to the variables of gender, experience, number of students, and the stage they are teaching. The researcher recommends that more research should be done on the effect of critical thinking on the four skills reading, writing, speaking and listening.

The aim of this study is to determine the relationship between critical thinking skills and reading comprehension.  Data was collected from treatment sessions, a self-evaluation and a test on critical thinking skills with two groups of learners from a language department at an Ecuadorian university.  The results showed insignificant relation between critical thinking skills and learners' reading comprehension.  The findings also revealed both groups had small differences during the pretest and posttest.  The pretest and posttest showed minimal changes between groups, as well.  Participants’ lack of concentration in texts, the unawareness and scarce use of their critical thinking skills were evidenced in their grammar, syntactic and semantics’ mistakes.  The implications of these findings suggest further research in this area, exploring teaching practices that foster students’ critical thinking skills and reading comprehension.
