Purpose of the study: This current study aims to analyze students’ critical thinking skills in learning chemistry specifically colloidal concept. Methodology: The research method used in this research is mixed-method by using explanatory sequential design. Data collection techniques used interviews, observation, and essay tests that have been developed based on critical thinking indicators by Ennis. This research is based on tests and interviews of students of class XI IPA in Pekanbaru. Quantitative data analysis techniques used a pre-experimental research design with one group pretest-posttest design and qualitative data analysis techniques used interviews and observation. Main Findings: Through essay tests, the average pre-test score was 30.15 and the post-test score was 50.67. The results provide information about high school students 'critical thinking skills about the concept of colloids which are still low so that alternative learning strategies are needed to improve students' critical thinking skills in chemistry learning. Applications of this study: The results of the research, expected to provide an overview for teachers and researchers about the condition of critical thinking skills of high school students in chemistry learning, specifically the concept of colloids. Novelty/Originality of this study: In this research, the novelty is the development of five indicators of critical thinking skills, the results of qualitative and quantitative analysis of students' critical thinking skills on colloidal concepts.

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.
