The Science, Technology, Engineering, and Mathematics (STEM) approach has become an interesting research object. Several studies have proven that the STEM approach has overcome various learning problems. It involves many teaching and learning aspects, either the cognitive, affective, or psychomotor domains, positively affecting the students' learning outcomes. This study aimed to describe the effect of the STEM approach with the Brainstorming method on critical thinking and creative thinking skills of students in physics learning. This study employed quasi-experimental research with a non-equivalent control group design. The sampling was done through the simple random sampling technique with a total sample of 60 high school students. The instrument used in this study was an essay test instrument to measure critical thinking and creative thinking skills. The Multivariate Analysis of Variance (MANOVA) was used as the research hypothesis testing technique. The results showed that the significance score of critical thinking skills was 0.001, and the significance score of creative thinking skills was 0.019. So, it can be concluded that the application of the STEM approach with the Brainstorming method is effective in improving students' critical thinking and creative thinking skills in learning physics, both through multivariate tests and separate tests.

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.

The use of portfolio assessment is believed to be a means of mastering a subject. This study was aimed to analyze whether the implementation of portfolio assessment in Biology learning in human coordination systems material can improve students' critical thinking skills. This study used a pretest and posttest control group design. Based on the results of the analysis, it was found that the means posttest score of students' critical thinking skills in the experimental class was 78.28, and the control class was 63.36. The Independent Sample T-Test showed a significant mean difference between the experimental class and the control class. The improvement of critical thinking skills by implementing portfolio assessment was better than the control class. The regression test showed that the contribution of the portfolio assessment to the improvement of critical thinking skills was 19.1%. The results of the analysis showed that the portfolio assessment distributed students in three categories of critical thinking skills were 59.4% in the enough category, 31.3% in the good category, and 9.4% in the very good category. The conclusion is that the implementation of portfolio assessment has a positive effect on increasing students' critical thinking skills in the human coordination system material.

Critical thinking ability is an important ability to have. However, students' mathematical critical thinking skills are still low. Efforts that can be applied are through the Metagontive Scaffolding learning approach. The Metcagontive Scaffolding approach has been proven to be able to improve mathematical communication skills, mathematical literacy, and self-efficacy. This study was conducted to test whether Metagontive Scaffolding can improve the mathematical critical thinking skills of junior high school students better than direct learning. This study uses a quasi-experimental method with a nonequivalent control group design. The population in this study were all eighth grade students in one of the public junior high schools in Bandung. This study uses two classes as a sample from a number of class VIII randomly graded. The data in this study were obtained through the results of the answers to students' mathematical critical thinking abilities. significantly compared to students who participated in direct learning

This study aims to investigate the effect of portfolio assessment in teaching physics and scientific attitude. The research was conducted on students of high school in Singaraja. Research was an quasi- experimental study by using “The Posttest-Only Control Group Design”. The research involved 152 high school students of class X of science as samples, taken with multistage random sampling technique. Portfolio assessment was integrated with physics learning. The implementation of the portfolio assessment included four key elements such as the students' work folders, clear assessment criteria, and self-assessment, and conference between teacher and students. The data needed in this research was the students' scientific attitude which included the aspect of curiosity, respect for evidence, the willingness to change ideas, and critical reflection. Data needed in this research included scientific attitudes students. A Likert scale instrument was used to measure the scientific attitude students. Data were analyzed using analysis of variance with SPSS 20.0 at significance level α = 0.05. The results showed there are differences in the scientific attitude students who take physics learning with assessment portfolios and students who take physics learning with assessment of conventional. The findings of this study indicate that portfolio assessment in learning physics significantly affect the scientific attitude students.

The ability to think critically and creatively is needed in solving math problems. Secondary school students in Indonesia still possess these two abilities according to the results of PISA research. Therefore, learning studies that influence these two abilities are still feasible to do. This study aims to examine the effect of MEA learning with contextual worksheets on the ability to think critically and creatively in solving math problems. The study was a quasi-experimental study using a post-test only control group design. The research population consisted of 137 class X students of SMK Kharisma Mengwi, Badung Regency, Bali for the 2019/2020 school year, which was spread into five classes with equivalent math abilities. A random sampling technique determined a sample of 2 classes. Data on the ability to think critically and creatively in solving mathematical problems were collected using a test in the form of a description. Data were analyzed using the MANOVA test. The results of the analysis show that MEA learning with contextual worksheets has a positive effect on the ability to think critically and creatively in solving math problems (F = 90.018; p <0.05).
