This research uses research and development (R&D) with the Plomp model. Besides, the research subjects are three teachers and 30 students in 11th grade from SMAN 8 Pekanbaru, SMAN 2 Pekanbaru, and MAN 1 Pekanbaru. Literature studies and field studies were carried out as the data collection techniques. The research data is obtained from the validation results of two material validators, two media validators, and user trials. The validation result to material validators has obtained the average based on the material aspect 96.00%, construction aspect 93.10%, and language aspect 99.00%. According to media validators, based on the content aspect 90.00%, learning design 84.00%, display (visual communication) 85.00%, and software utilization 95.71%. The analysis of the questions showed that ten questions were valid, had very high reliability, a medium difficulty level of five questions, and a difficult category of five questions and had good distinguishing power. User response scores are 88.00% by teachers and 95.23% by students with very good criteria.","PeriodicalId":33527,"journal":{"name":"JTK Jurnal Tadris Kimiya","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87250079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, new learning designs of REE need to be developed for Pre-service Chemistry Teachers (PCT) as it is not yet available. A good design is constructed by analyzing PCT pre-conceptions based on the technical difficulties faced by the students during teaching process. The study aims to identify PCT's pre-conceptions focusing on REE topic. We conducted this research involving 17 chemistry education students at the Universitas Pendidikan Indonesia, Bandung. Data was collected through interviews and analyzed using the Qualitative Content Analysis (QCA) method. Our results highlight that PCT had difficulties with chemistry content of REE, especially about electronic configuration, magnetic, and luminescence properties. In addition, PCT faced difficulties correlating electronic configuration's chemistry content into contexts. Based on the interview results, 88.2% of the students agree with the development learning design for undergraduate chemistry students. As a result, we conclude that technical difficulties and misconceptions about REE can be overcome by developing the learning design based on the need of the students.

However, the current student’s scientific literacy ability is relatively low. The millennial generation has been named as a generation that has an environment-friendly attitude. In cases that occur in the field, many students still litter and are not friendly to the environment. There are no teaching materials that develop scientific literacy and environment-friendly attitudes in implementing STEM (Science, Technology, Engineering, and Mathematics) with the principles of Sustainable Development Goals (SDGs). This research aims to produce a STEM e-module with the principles of SDGs to improve scientific literacy and environment-friendly attitudes of 11th grade students regarding gender that is valid, practical, and effective. This research is development research (R&D) with the Plomp model. The data analysis results show that the STEM e-module with SDGs principle has a good impact on students' scientific literacy skills and environment-friendly attitudes. The developed e-module can also help students practice scientific literacy and improve a better environment-friendly attitude.","PeriodicalId":33527,"journal":{"name":"JTK Jurnal Tadris Kimiya","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77577743","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to determine aspects of critical thinking skills developed in questions in the Chemistry High School textbook. The research method used is a descriptive method and multistage sampling technique. There are six books analyzed. The research instrument used was in the form of observation sheets classifying questions based on indicators of critical thinking skills. The results showed that the questions developed in Chemistry textbooks were analyzed based on critical thinking skills, including aspects of making simple explanations with a percentage of 28.8%, building basic skills of 20.3%, concluding at 45.8%, giving further explanations of 3.4%, and set strategy and tactics of 1.7%. The questions developed are dominated by concluding questions.

The low independence of student learning affects critical thinking skills in solving a learning problem. A project-based learning model can improve critical thinking skills and independent learning. This study aims to analyze the application of the PjBL model to manufacture colloids to improve students' critical thinking skills and independent learning at MAN 1 Banda Aceh. The type of research used is quasi experimental. The samples of this study were students of natural science two 11th grade as control class and students of natural science four 11th grade as experimental class, which had normal distribution and had the same variance. The instruments of this research are the CTS test questions and learning independence questionnaires. The results show that applying the PjBL model can improve critical thinking skills (CTS) with an average N-gain value in the medium category, then the CBC analysis of indicators is in the high category. The results of testing the CTS hypothesis for experimental class and control class students are also significantly different, meaning that the CTS model can improve students' critical thinking skills. The analysis of student learning independence results obtained an average score of N-gain, including the medium category. The results of the hypothesis test of student learning independence in the experimental and control classes are also significantly different, meaning that the PjBL model can increase learning independence. The results obtained prove that the PjBL model can improve CTS and learning independence better than in the control class.","PeriodicalId":33527,"journal":{"name":"JTK Jurnal Tadris Kimiya","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88604753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
