Critical thinking skill is the priority in the goals of education. In this case, the critical thinking has the higher process, such as analyzing, synthesizing, evaluating, drawing conclusion and reflecting which enables the individual to make the reasonable assessment both in the classroom and in the daily life.  This research is aimed to determine the students’ critical thinking skill in learning Chemistry at senior high school. This research used descriptive method in which the instruments were developed based on the indicators of critical thinking skill. The population of this research was 100 students of tenth, eleventh and twelfth grade from senior high schools in Surakarta which was chosen using cluster random sampling technique. The result of the research shows that the students of tenth, eleventh and twelfth grade have adequate critical thinking skills.

This Mathematics critical thinking skill is one of the components a student must possess. This skill will assist them to be able to make the right decision. In fact, however, not many of them having a high of critical thinking skill. It causes them to be lack of skills in completing the mathematics cases. This research aims to: (1) describe the critical thinking skills of junior high school students in solving mathematical problems and (2) identify the students' critical thinking components in the focus, reason, inference, situation, clarity, dan overview. This was descriptive research with a qualitative approach. This research involved 32 subjects comprising 15 male students and 17 female students. The method used in this research is test, interview, and triangulation. The test used in this research consisted of 6 problems representing 6 sub-skills of critical thinking skills. The results of data collection were analyzed through data reduction, data display, and conclusion drawing. The findings showed that: (1) the critical thinking skills of junior high school students were in a low category; (2) overview became the lowest critical thinking sub-skills mastered by the students compared to other critical thinking sub-skills

Test Instrument

Critical thinking skills is one of 21st century skill. This requires students to solve the problems they face. Therefore, it need a test instrument that can assess students' critical thinking skills. This study aims to develop instrument test of critical thinking skills of high school students by two tiers test format related to temperature and heat concept. The research method used was the ADDIE development model (Analyze, Design, Development, Implementation and Evaluation) conducted by 11th grade high school students who have studied temperature and heat concept. The number of respondents of research as many as 30 students in 11 grade senior high school in Bandung. Data collection using the Halpern framework critical thinking skill instrument test adapted by Tiruneh by two tiers test format. The results obtained that the test instrument of critical thinking skills related to temperature and heat concept by two tier test format can assess students' critical thinking skills. Thus, the development of critical thinking skill test by two tier test format has the potential to be one of the test instrument for assessing and trained students' thinking skill.

The Problem-Based Learning with Argumentation (PBLA) model is a development model of Problem-Based Learning (PBL) added to the Toulmin Argumentation activity to increase the critical thinking skill in junior high school. The research aims to determine the feasibility of PBLA in terms of its validity and effectiveness. The research samples are two groups of students (class 1 and class 2) with 26 students in each class. Before learning to use PBLA, each class was given a pretest, and after learning to use PBLA were also given a posttest. PBLA validity data were obtained through validity sheets and analyzed through expert agreement. PBLA effectiveness data was obtained through critical thinking skill tests and analyzed by paired t-test, n-gain, and two-average similarity test. The results showed that the content validity and the construct validity categorized as valid with a score of 3.5 and 3.3. The reliability scores obtained are 77.10% and 77.67%. The critical thinking skill data showed a significant increase in critical thinking skill at α = 5%, the average n-gain was categorized high, and there was a similarity in increasing critical thinking skills for the two classes. In conclusion, PBLA is effective in increasing critical thinking skills for junior high school students

In 21st century learning, critical thinking skills are the main choice that must be mastered by students. This study aims to determine the effectiveness of local wisdom-based science teaching materials in improving junior high school students’ critical thinking skills. Most science teachers still apply teacher-centered learning, so students tend to be passive. This type of research is quasi-experimental with a pretest-posttest control group design. The study was conducted in the even semester of the 2019/2020 school year. The subjects of the research were grade VII students. Data collection techniques and instruments in the form of tests that include indicators of critical thinking skills. Data analysis used homogeneity test, Kolmogorov Smirnov normality test, independent sample t-test, and n-gain score. The results of the independent sample t-test are sig. (2-tailed) = 0,000<sig. α = 0.05. Students’ critical thinking skills in the experimental class were higher (N-gain score = 39.09%) than in the control class (N-gain score = 12.03%). Based on the study results, it can be concluded that there is a significant influence on the application of local wisdom-based teaching materials in improving the critical thinking skills of middle school students in the moderate category.
