Abstract

To ensure the success of science learning oriented to higher order thinking skills, especially scientific communication skills (SCS), valid and effective instruments are needed. The existing instruments, although helpful, are still too general and have not touched the socio-cultural context. Therefore, we developed an instrument to measure SCS according to the characteristics of students in Indonesia. This study tested the validity, reliability and assumptions of the hypothetical model of the scientific communication skills inventory (SCSI) instrument developed. This study involved 1,287 students in Indonesia. The test was carried out through confirmatory factor analysis with structural equation modelling (SEM) using AMOS version 21. The results of the analysis show that the reliability of the instrument based on Cronbach’s alpha coefficient is 0.720. The convergent validity test detected one item of the oral presentation indicator as invalid and the discriminant validity test confirmed that all instrument items were declared valid. The goodness of fit test shows all scores according to the recommended standard criteria so that SCSI can be used to identify the SCS ability profile of students in Indonesia. For further research, we recommend the development of a learning model that prioritizes the context of social issues to grow students’ SCS.

Abstract

This study aims to test the effectiveness of integrated differentiated PjBl-STEM e-LKPD to improve science literacy. This research method uses the ADDIE R&D model. Classes IX.A, IX.B, IX.C, and IX.D at SMPN 1 Tanjung Bintang became the research sample with purposive sampling. The data analysis technique used the independent sample t-test and ANOVA. Based on expert validation, the percentage of content suitability aspects was 96.42%, construction suitability 96.25% and readability 90%. The average percentage of teacher responses to the content aspect was 95%, readability 93.75%, and attractiveness 98.75%, as well as the results of observations of learning implementation 77.4%, and reflection questionnaires with high criteria. In addition, the percentage of student responses to the readability aspect was 86.25% and attractiveness 90%. Based on these results, the developed e-LKPD is valid and practical with a very high category. The results of the t-test stated that there was a significant difference in the average scientific literacy of students between the control and experimental classes. The results of the ANOVA test stated that there was no effect of using e-LKPD with visual, kinesthetic, and auditory learning styles in improving scientific literacy because the e-LKPD developed had accommodated the needs of all students.

Abstract

This preliminary study explores the needs of teachers and students in physics learning, focusing on renewable energy topics. Using a survey method, data were collected from 24 high school physics teachers in Lampung Province via Google Forms. The findings were analyzed to identify educational gaps and propose solutions. Results reveal a pressing need for learning programs that enhance Collaborative Problem-Solving and Entrepreneurial Skills. While 83.30% of teachers reported integrating Project-Based Learning STEM (PjBL-STEM) into their teaching, only 23.50% of worksheets used were PjBL-STEM-based, and just 26.70% were self-created. Teachers faced challenges such as limited time and difficulty initiating development. Additionally, only 54.20% of teachers were familiar with the Sustainable Development Goals (SDGs). The study also highlights gaps in skill assessment, with 75% of teachers not evaluating Collaborative Problem-Solving Skills and 87.50% not assessing Entrepreneurial Skills. Despite using teaching media and worksheets, these gaps suggest a need for more robust tools and methods.The findings underscore the importance of developing renewable energy learning programs integrated with PjBL-STEM. Such programs can address existing challenges, promote SDG awareness, and equip students with critical skills for collaboration and entrepreneurship in the context of physics education.

Abstract

This study aims to produce an interactive learning multimedia application product based on Android integrated with STEM heat material that is valid, practical, and effective in improving students' computational thinking skills. This research and development was carried out using a 4D model consisting of defining, designing, developing, and disseminating. This study uses a mixed methods concurrent embedded model consisting of five stages of data collection, namely qualitative data collection followed by quantitative data collection followed by providing interventions in the form of qualitative data collection followed by quantitative data collection and finally qualitative data collection. The trial design used was a non-equivalent pre-test post-test control group design. The subjects of the study were 64 junior high school students, 32 in the experimental class and 32 in the control class. The results of the study showed that the resulting product was stated as: very valid (94%) by material experts, (95%) by media experts; very practical to use in learning by students (91%), with a very high level of learning implementation, namely (94.57%); effective in improving students' computational thinking with high n-gain (0.77) and effect size with criteria of (91%). Based on the results of research and data analysis, it shows that the developed product can be used in learning heat material to improve students' computational thinking abilities.
