Critical thinking skills bears a fundamental role in students’ thinking process and achievement. Meanwhile, the cornerstone of critical thinking is a metacognitive activity that has a substantial function in measuring and evaluating the obtained information, as well as learning from the experience. This study aims to examine students’ critical thinking and metacognitive skills before and after they participate in the PBL classroom using a project guide e-book for the genetic one course. The student’s critical thinking skills were assessed using written tests using open-ended question items. Further, the obtained scores were analyzed using paired t-test. The data analysis suggested an increase in students’ metacognitive and critical thinking skills after they attended the PBL class using the PBL-based project guide e-book for genetic 1. This increase was shown from the 0.000< α (α = 0,05) significance score of paired t-test. Thus, the PBL-based project guide e-book for the genetic 1 course is capable of enhancing students’ metacognitive and critical thinking skills.

Critical thinking skills are very important to be acquired by the students in the 21st century. In science learning, students are required to think critically. However, students’ critical thinking skills at the junior high school level are included in the low category. The 5E learning cycle model is the learning model that is considered can train the student's critical thinking skills optimally. The purpose of this study was to examine the effect of the 5E learning cycle model on junior high school students' critical thinking skills in science learning and to describe the improvement of junior high school students’ critical thinking skills. This type of research is experimental research with a quasi-experimental design and nonequivalent (pretest and posttest) control-group design. The results of the study for the effect test using the independent sample t-test obtained the value of Sig. (2-tailed) of 0.016 which means <0.05. The implication is that the 5E learning cycle model has a significant effect on the thinking skills of junior high school students in learning science. For the improvement test using N-Gain, an average N-Gain of 0.5875 was obtained which was included in the moderate category, then the results of the paired sample t-test obtained a Sig value. (2-tailed) of 0.000 which means <0.05. The conclusion was the 5E learning cycle model has a significant effect on junior high school students’ critical thinking skills in science learning and it can improve junior high school students' critical thinking skills in the moderate category.

This study was an online classroom action research (PTK) due to the COVID-19 pandemic. This study aimed to improve learning outcomes in calculus classes for physics engineering students using think pairs share. The online think pairs share (OTPS) learning model was optimized using the Learning Management System (LMS) platform in two learning cycles. The research sample was 46 students in the study program of physics engineering. The data were obtained from the pre-test-post-test scores, group discussions, and individual presentations. The results showed that the pre-test and post-test scores in cycle I were 37.16 and 68.41, while in cycle II, 41.20 and 68.65, respectively. In addition, the daily student score from the group discussion and individual presentation was 60.68 for the cycle I and 60.15 for cycle II. Furthermore, inferential analysis using the Kolmogorov-Smirnov test proves that tcount > ttable. Hence, the result indicated that implementing the OTPS learning model optimized using LMS could improve the student learning outcomes in calculus.

Hence, the result indicated that implementing the OTPS learning model optimized using LMS could improve the student learning outcomes in calculus.","PeriodicalId":33562,"journal":{"name":"Prisma Sains Jurnal Pengkajian Ilmu dan Pembelajaran Matematika dan IPA IKIP Mataram","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47943110","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}

Scientific literacy is seen not only as an important component of science education, but also as an ethical/moral competency. Science education plays an important role in creating responsible citizens, in this case scientific literacy is needed in making social-scientific decisions. Currently the concept of scientific literacy is a learning goal in the educational curriculum in various countries. Scientific literacy emphasizes students to analyze, predict, and apply scientific concepts in everyday life. Likewise with students in South Konawe district for the junior high school level, the majority of whose scientific literacy results are classified as lacking. Therefore, this research focuses on the Analysis of Science Literacy Ability of Junior High School Students Using the Nature of Science Literacy Test (NOSLiT) Method in Konawe Selatan Regency. The research method used in this research is quantitative with a descriptive approach. The sampling technique in this study used a simple random sampling technique. The result is that the scientific literacy skills of SMPN Konawe Selatan students based on the NOSLiT instrument in class IX are still in the low category while those in class VII and class VIII are classified as very low. This can be seen from the acquisition of the overall average NOSLiT score for all grade levels, namely 37%, 39.4% and 45.5% respectively, and after calculating the overall score, the average percentage of scientific literacy ability of Konawe Middle School students is obtained. South is in the low category of 40.8%. The achievement of scientific literacy for the NOSLiT indicator of SMPN Konawe Selatan students at all grade levels obtained the highest percentage of achievement in the scientific naming aspect, followed by the scientific misconception aspect, and the ability to process skills and the lowest percentage of achievement lies in the aspect of science postulates. In general, the highest achievement for all NOSLiT indicators was obtained by class IX, followed by class VIII and class VII. The percentage achievement for class IX for indicators of scientific naming, process skills ability, and major misconceptions reached 50% and was above 50% but still this percentage is still in the low category.
