The learning process only focuses on the material by memorizing concepts, students do not use LKPD to do practical work optimally, so the biology learning process in schools does not encourage students to practice critical thinking skills. This study aims to improve students' critical thinking skills by using the PBL learning model combined with STEM-based worksheets on environmental pollution conceptin class 10th SMA Negeri Bireuen district. The approach used is experimental design, the method used is quasi-experimental, with a pretest-posttest design non-equivalent control group design. Population in class 10th IPA SMAN 1 and SMAN 2 Peusangan designed 252 people. The sampling technique used was purposive sampling technique. The research sample was 140 students. The number of samples in the experimental class was 71 people and 69 people in the control class. The instrument used was a reasoned multiple choice question accompanied by a rubric. The data analysis used was n-gain and independent t-test. The results showed that the critical thinking skills obtained was 0.93, with an increase in class critical thinking skills including the high category. The results of the independent sample t-test obtained Sig. (0,000) α (0.05) then Ha is accepted, so it is suggested that there are differences in the critical thinking skills of students between the experimental class and the control class on environmental pollution material in class X SMAN Bireuen. The implementation of PBL learning model combined with STEM-based LKPD can improve students' critical thinking skills on environmental pollution material in class 10th SMA Negeri Bireuen Regency.

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.

Abstract:The accountant profession in the 21st century requires good critical thinking skills so that developing the skills needed in the 21st century is necessary in the accounting student’ learning environment. Therefore, the technology can be used as a medium for learning and communication between the students and the lecturers. In addition, the problem based learning model as a learning that requires the students to actively participate in each learning to develop the critical thinking skills so that the integration between problem-based face-to-face learning and learning utilizing technology in e-learning media is expected to improve the students’ critical thinking skills and the learning motivation. The research aims to: (1) find out the implementation of an effective blended learning model towards the students’ critical thinking skills and the learning motivation, and (2) to find out the difference in the students’ critical thinking skills and the learning motivation between the experimental class and the control class. This research is a quasi experimental research with non equivalent control group design. The study used one experimental group and one control group. The population in this study was the students who took introductory courses in accounting and accounting information systems so that the samples were taken by using purposive sampling technique. The instruments used are the essay test for the critical thinking skills and the questionnaire for the learning motivation. The data analysis techniques used are paired sample t test and independent sample t test assisted by SPSS 26.00. The findings show that: (1) the results of the paired simple t test show that the implementation of the blended learning model effectively improve the students’ critical thinking skills and the learning motivation, and (2) The results of the independent simple t test show that the students’ critical thinking skills and the learning motivation of the experimental class have a significant difference with the students of the control class.Abstrak:Profesi akuntan pada abad 21 membutuhkan keterampilan berpikir kritis yang baik sehingga diperlukan lingkungan belajar mahasiswa akuntansi yang mampu mengembangkan keterampilan yang dibutuhkan di abad 21.

Development Approach

This study was motivated by the fact that the process of learning the Quran Hadith subject in Madrasah Aliyah is still far from developing the students' critical thinking skills, caused by the learning process most focused on result and value (product oriented). This study aimed to generate and develop a learning model to improve student’s critical thinking skills. This research was conducted using research and development approach (R & D), included (1) a preliminary study, (2) Model Development, and (3) Test validation. Model testing carried out by experiment in the form of a quasi-experimental design with pretest-posttest control group design. The results showed that the learning model developed proved more effective to improve the processes and outcomes of learning the Qur'an Hadith. In terms of the learning process, the implementation of this model can improve the performance of teachers, namely; more effective learning time, learning more concentrated and more controlled learning activities.

Thinking Ability

Mathematical Critical thinking is one of  mathematical abilities that must be obtained by students. Critical thinking is one of the high order thinking processes that can make concepts in student knowledge.  Students with critical thinking in mathematics learning mostly do rational activities such as interpreting information based on a particular theoretical framework, linking theory with practice, making claims and justifying it, utilizing data in support of argumentation, making relations or relationships between various ideas, asking questions, evaluating knowledge, predict, describe something, analyze, synthesize, and categorize. This study aims to analyze the effect of the Concept-Based Learning Model on the critical thingking mathematical abilities.The purpose of this research is to analyze the effect of Concept-Based Learning Model toward mathematics critical thinking ability. The method used in this research is quasi experiment by Randomize Control Group Post Test Only Design with cluster random sampling technique. Indicators of mathematics critical thinking skills measured in this study include providing simple explanations, building basic skills, concluding, making more explanations, and deciding an action. The results showed that the mathematics critical thinking ability of students in the experimental class for the five indicators that being analyze was higher than the ability of students in the control class. A fairly high difference in the indicator showed in give a simple explanation and concluding. and it means that the application of Concept-Based Learning Model significantly influences the  abilities  of students' mathematics critical thinking.
