Teachers as learning agents must be able to present the learning process contextually by involving the active participation of students. Some students learn best when they have the opportunity to interact with real objects through inquiry activities that will help students deepen their understanding of a concept. Inquiry learning is one that can be adapted to students' abilities, can build cognitive structures, and can motivate students to think critically. This research is classified as descriptive research. The subjects of the research were students of class X SMA Negeri 4 Barabai as many as 78 students in the 2015/2016 academic year on the mushroom group material. The research data were in the form of observations on students' critical thinking skills which were analyzed descriptively using categorical methods, namely very good (≥ 3), good (2-2.99), not good (1-1.99). While cognitive learning outcomes were obtained through tests and success was determined based on KKM = 67 with classical completeness 85%. The results showed that students' critical thinking skills were at least good, namely formulating hypotheses, designing experiments, conducting experiments, and making conclusions, while formulating problems, and analyzing data still needed improvement. Meanwhile, students' cognitive learning outcomes have not yet achieved minimal completeness. Keywords: critical thinking skills, learning outcomes, inquiry AbstrakGuru sebagai agen pembelajar harus mampu menyajikan proses pembelajaran secara kontekstual dengan melibatkan langsung peran serta siswa secara aktif.

This study aims to analyze the critical thinking skills of P21 students in solving Arithmetic Two Dimensional problems through the application of Guided Discovery Learning. GDL is a learning process that occurs when students are not presented  with material in final form but learners are expected to organize their own material with guidance from educators if needed. Implementation of GDL in learning process is expected to improve students' thinking ability, especially critical thinking ability version P21. According to P21, in the 21st century, every individual is required to have 4C's skills in order to compete globally and one of 4C's skills is critical thinking. By having these skills, learners are expected to achieve success in life and work. The subjects of this study are discrete mathematics class students, as many as 64 students. Research steps are by providing initial knowledge of Two Dimensional Arithmetic materials through GDL method and Student Worksheet (LKM) then at the end of student learning work on Test Mastery of Teaching Materials (TPBA). The test results are then analyzed using the P21 critical thinking indicator that is reasoned effectively, using a system of thinking, making judgments and decisions. From the analysis result of Teaching Material Mastery Test obtained data about critical thinking level of students, in class A there are 25 students being in very high category (level 4), 10 students are in high category (level 3) and 9 students are in medium category (level 2). While in class C there are 22 students being in very high category (level 4), 4 students are in high category (level 3) and 4 students are in medium category (level 2). The study also produced a two dimensional arithmetic monograph. From the results of this study can be concluded that the application of GDL has a positive effect in developing students' critical thinking skills in solving two-dimensional arithmetic problems.

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.
