Rare Earth Elements (REE) is an interesting chemistry topic, especially due to current technology development. 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.

Scientific literacy plays an important role in developing education in the 21st century. 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.

Chemistry textbooks' questions are important in improving students' thinking skills. Various types of questions are developed, but the effectiveness of these questions in supporting student success is something that is not expressed enough. 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. Thus, it can be concluded that the questions in the Chemistry High School textbook have not been developed evenly on the five aspects of critical thinking.

Critical Thinking Skills (CTS) and student learning independence are two things related to the learning process. 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.

Research and Development (R&D) method was used in this study with a Plomp model. This model included three phases: preliminary, prototype or development, and assessment. Validation sheets and response questionnaires were used as research instruments. Six expert lecturers, consisting of three media and materials experts each, assessed the validity sheets. A small-scale test was carried out utilizing two approaches; a one-to-one test and a small group test. A one-to-one test was given to three students who had high, medium, and low abilities; while the small group test was conducted on three teachers and 30 students from three different schools, which are MAN 2 Pekanbaru, MAN 1 Pekanbaru, and SMA IT Al-fitiyah. The results showed that the interactive e-module was very valid and could be used in learning activities. This is indicated by the percentage of validation from material experts 89.27% and media experts 88.76%. In a small-scale trial for a one-on-one test, the teacher's response 95.83% with very practical criteria; and student response test 87.73% with interesting criteria.","PeriodicalId":33527,"journal":{"name":"JTK Jurnal Tadris Kimiya","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79874808","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}
