The broad scope of biology and the many sources of biology reading requires eleven grade students to think critically about sorting out information to develop and support students' critical thinking skills. CirGi is an integration of the cooperative integrated reading and composition (CIRC) learning model and guided inquiry (GI) that emphasizes reading and writing activities, accompanied by guidance from the teacher. This study aimed to analyze the influence of CirGi's learning model on students' critical thinking skills. This research uses a quasi-experiment method with pre-post control group design. The sampling technique used purposive sampling, namely 104 high school students. Data collection was carried out using instruments of critical thinking skills in the form of essays, questionnaire responses of students to learning, and observation sheets of syntax implementation. The data analysis technique used was one-way ANCOVA. After controlling for the pretest scores, the CirGi learning model's influence on students' critical thinking skills was influenced. This learning model was appropriate for learning biology, so it can regrow the activities of reading science books that impact students' critical thinking skills.

This study aims to identify the effect of using a STEM-oriented (Science, Technology Engineering & Mathematics) teaching program in teaching mathematics on critical thinking skills among high school students in the Riyadh educational region in the Kingdom of Saudi Arabia. The sample of the study consists of (88) male and female students selected randomly from the "Advance Schools for Smart learning" in Riyadh city, where the semi-experimental approach is used. The results of the study show that there are statistically significant differences between the averages of the degrees of analysis skill, induction skill, reasoning skill, skill of conclusion, and evaluation skill in favor of the experimental group. The results also showed a statistically significant difference between the mean scores for the analysis skill, the induction skill, the reasoning skill, the conclusion skill and the evaluation skill for the benefit of the experimental group. The results also show a statistically significant difference between the mean scores for the scale skills as a whole and for the benefit of the experimental group. The results of the study show that there are no statistically significant differences between the mean scores of the critical thinking test skills and the total score attributed to the gender variable (male and female). The study recommends adopting the STEM approach in teaching science, technology, engineering and mathematics subjects, and redeveloping and building the content of science and mathematics curricula for the secondary stage through relying on science standards for the next generation, and working on adopting a special curriculum to teach the STEM approach and include it in the next plan for general education stages.

PENILAIAN KETERAMPILAN BERPIKIR KRITIS DAN PENGUASAAN KONSEP PADA MATERI EKOSISTEMAbstractCritical thinking skills and mastery concepts are competencies that measure cognitive aspects. Both of these competencies support each other. This study aims to analyze critical thinking skills and mastery concepts of students in the ecosystem material. This was quantitative research. The sampling technique used Purposive Sampling, namely 60 high school students. Data was collected through the critical thinking skills test and mastery concept of ecosystem tests for students and interviews with the teacher. Based on the analyzed data, the average critical thinking skills and mastery concepts of an ecosystem are 53,15 and 61,10, which are in the low category. This is because students still have difficulty in understanding the basic concepts of ecosystems; students have not understood yet the terms in the ecosystem so that the terms with their meanings are often exchanged which has an impact on the low achievement of students.AbstrakKeterampilan berpikir kritis dan penguasaan konsep adalah kompetensi yang mengukur kemampuan kognitif. Kedua kompetensi tersebut saling berkaitan dan mendukung satu sama lain. Penelitian ini bertujuan untuk menganalisis keterampilan berpikir kritis dan penguasaan konsep peserta didik pada materi Ekosistem. Penelitian ini merupakan penelitian kuantitatif. Teknik pengambilan sampel yang digunakan adalah purposive sampling, yaitu 60 peserta didik SMA. Data diperoleh melalui tes tentang keterampilan berpikir kritis dan penguasaan konsep pada materi Ekosistem yang dikerjakan oleh peserta didik dan wawancara dengan guru. Berdasarkan analisis data, rata-rata keterampilan berpikir kritis dan penguasaan konsep materi Ekosistem peserta didik, masing-masing adalah 53,15 dan 61,10. Hasil tersebut termasuk dalam kaegori rendah. Hal ini disebabkan oleh sulitnya peserta didik dalam memahami konsep dasar Ekosistem, belum mengertinya istilah-istilah dalam ekosistem sehingga sering terjadi pertukaran istilah dengan maknanya yang berdampak pada rendahnya prestasi belajar siswa.

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.
