Student's critical thinking has not been maximally train in learning, learning activities are only memorizing demands of passing the assessment. Students are less understand, build, and criticize arguments about a problem, especially in science learning. This is the introduction for the development of teaching materials based on Science, Environment, Technology, and Society (SETS). This study aims to determine how the feasibility of science teaching materials based on SETS in ecosystem materials to improve the critical thinking skills of grade 5 students. This type of research is research and development (Research and Development) with a 4D model. This research was conducted online using Microsoft Teams which was carried out synchronously and asynchronously due to the Covid-19 pandemic. The data collection technique is the expert validation stage, the implementation of learning observation sheets, critical thinking tests (pretest and posttest), and student response questionnaires and then analyzed using quantitative and descriptive techniques. The results show that: (1) teaching materials were in the feasible category with an average of 3.4, (2) practical based on observations of the implementation of learning with an average of 93% and the categories are good, and 95% of the student activity was active, ( 3) effective based on the acquisition of N-gain on the critical thinking test is 0.77 (high category), and the student response questionnaire that is 97% very good category.

Chemical bonding was one of the subjects considered difficult by students, because it had submicroscopic concept that learns about the formation of bonds an element that was quite difficult for students to understand. The development of teaching material in the form of teaching materials was seen as a solution to this problem. This study aimed to develop chemical bondinginquiry modelsteaching materials with conflict cognitive strategies towards critical thinking skills. This studywas development research with ADDIE (Analysis, Design, Development, Implementation, and Evaluation)model design. The development results were validated by three expert validators, one practitioner validator and ten IKIP Mataram students as students' limited test validators. Quantitative data from the results of feasibility validation and the results of the assessment of student attitudes toward critical thinking skills were analyzed by percentage formula and the results of effectiveness test data were calculated by N-gain. Qualitative data in the form of responses and suggestions for improvement from the validator was used as a consideration to make revisions to the instructional materials developed. In general, the validator's assessment of the results of the development obtained an average percentage of 83.80%, 85.71%, 88% and 85.71%. While the results of the analysis of effectiveness using the N-gain test obtained an average score of 0.6 with the medium category and analysis. This showed that the teaching materials developed were very feasible to proceed to a broader and more effective stage to foster critical thinking skills.

This study aims to determine the effect of the implementation of the inquiry type CTL learning model on critical thinking skills. The population in this study were eighth grade students of MTs. Al-Asy’ariyah Bandar Lampung Year 2015/2016. The research method used in this study is Quasi Experimental Design. The research design used in this quasi-experimental was the pretest-posttest control group design. The sampling technique is random sampling. The sample in this study consisted of two classes namely the experimental class and the control class. Data collection techniques in the form of tests to measure students' critical thinking skills and observations to observe behaviors that arise in students according to indicators of critical thinking skills. The results of hypothesis testing obtained thitung = 5.78, while ttabel at a significance level of 5% by 2.00, it can be said that thitung > ttabel. This shows that Ho is rejected and H1 is accepted, meaning that there is an influence of the inquiry type CTL learning model on students' critical thinking abilities.

This study was conducted to develop temperature and heat learning media for high school students to improve their critical thinking skills regarding the phenomena related to temperature and heat material. This study uses the DDDE (Decide, Design, Development, Evaluation) method. This research begins with the stages of determining digital comics as learning media, compiling storylines and sketching comic images, compiling complete comics along with character dialogues, and evaluating the final results of digital comics. Three validators carried out validation test. The results of the validation test showed that digital comics were significantly suitable to be used as supporting media for temperature and heat learning based on several criteria, including learning aspects of 89.78%, material aspects of 93%, and media aspects 93.17%. These digital comics were consequently suitable to be used as a medium for supporting online learning and had time efficiency in delivering material. The implication of this study will facilitate the teaching and learning process from home or School from Home (SFH) during the pandemic period and is expected to be developed in further studies.
