Arguing ability was a part of critical thinking skills which important to be mastered by the students. In fact, students’ ability to argue was still relatively low. This referred to the TIMSS report (The Trends in International Mathematics and Science Study) in 2011, and showed that Indonesian children’s level in science was positioned in 42 from 45 countries. One kind of efforts to improve the quality of the ability to argue was applying the model of guided inquiry. This study was aimed to develop inquiry-based learning tools (PPBIT) and analyzed its effectiveness in developing the ability to argue of students at SMAN 2 Taliwang-West Sumbawa. PPBIT was carried out by applying 4D procedure. Then, pretest posttest control group design also completely concerned in determining the effectiveness of PPBIT. There were 66 students as the sample which was scattered from two classes and was selected by using purposive sampling technique. The results showed that PPBIT was appropriately to be used for students argumentation  skills’ activities by an average of feasibility syllabus 78.71%, RPP 83.5, LKITS 75%, and Instruments KB 80.25%, and effective in improving the ability to argue the class X SMAN 2 Taliwang, particularly on the subject of environmental pollution and recycling of waste by the average score of the students' ability from 48.22 up to 85.08Keyword: PPBIT, Argument

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.

This study aimed to determine the improvement of students' critical thinking abilities through the application of edmodo's assisted discovery learning model. The study was conducted on students of class XI MIPA 2 high school 2018/2019. This study used a true experimental design in the form of a pre-test and post-test control group design. Sampling was done by a cluster random sampling technique. Data collection used reasoned multiple choice test instruments and questionnaires. The result of test analysis of students' critical thinking skills showed that the average post-test value of the experimental class was lower than the control class. The N-gain test result showed that the magnitude of the increasing of the experimental class was 0.43 lower than the control class which is equal to 0.57. The application of edmodo assisted discovery learning model had a positive effect on students' critical thinking abilities with a low category as indicated by the correlation coefficient of 0.37 and the magnitude of the influence given is 14.08%. The conclusion of this study is the application of edmodo assisted discovery learning model can improve students' critical thinking skills. Furthermore, students agree to use edmodo's assisted discovery learning model for acid base learning.
