Abstract

Students have difficulty understanding physics concepts because they cannot connect them with everyday life. As a result, they study concepts separately and do not understand the relationships between concepts, especially on the topic of renewable energy, which are interconnected and play an important role in future life. This study aims to analyze the influence of the STEM-based Project-Based Learning model on students' system thinking abilities. A quantitative approach was used with a quasi-experimental design in the form of a Nonequivalent Control Group Design. The sample consisted of 62 tenth-grade students divided into experimental and control classes. The experimental class received the PJBL-STEM treatment, while the control class used the Problem Based Learning model. The highest improvement was observed in the coherent indicator, while the lowest improvement was in the intermediate indicator. These findings indicate that PJBL-STEM is effective in enhancing students' system thinking abilities, with an N-Gain value of 0.76 in the high category. This research is beneficial as an alternative learning strategy that can develop students' thinking skills and contribute to designing learning that is relevant to students' real-life contexts.

Abstract

Science literacy is an important competency in facing global challenges, as emphasized by international assessments such as PISA. Current physics assessment instruments used in schools are not aligned with the PISA 2025 framework, especially in measuring higher-order thinking skills. This study aims to identify gaps in the use of physics test instruments that refer to science literacy at the school level based on the PISA 2025 framework. This study uses a mixed-methods explanatory sequential design method, analyzing 923 questions: daily tests, textbooks, practice questions, 2013 curriculum teaching materials, and independent curriculum modules. The questionnaire was given to 85 students and four teachers in 4 schools, namely Jakarta and South Tangerang. The results showed that only 6.9% of the questions measured the identification of scientific information, while those measuring higher-order skills, such as analysis, were 2.9% and evaluation of evidence was 1.9%. Interestingly, 83.3% of the questions were irrelevant to the PISA science literacy criteria. This study reveals the mismatch of assessment in schools with international standards and recommends the development of contextual and PISA 2025. These findings provide an important foundation for educators and policymakers in improving the quality of science learning

Abstract

Conceptual understanding involves a deep comprehension of a concept, including the ability to explain, illustrate, and apply it in various contexts. This study aims to compare students’ levels of conceptual understanding under the Kurikulum Merdeka and the Cambridge Curriculum. A comparative descriptive method with a mixed-methods approach was used, employing a six-tier diagnostic test, interviews, and classroom observations. The sample consisted of 60 students selected through purposive sampling. The results showed that students following the Kurikulum Merdeka had a higher percentage of scientific understanding (43.4%) compared to those in the Cambridge Curriculum (20.3%). These findings indicate that the effectiveness of instruction is influenced not only by the curriculum strategy but also by factors such as the timing between instruction and assessment, students’ confidence in their responses, and language barriers. Therefore, instructional approaches should be aligned with students’ cognitive readiness and contextual conditions to optimize conceptual understanding.

Abstract

This study aims to develop a valid, reliable, and practical science literacy test instrument based on the PISA 2025 framework as a tool for assessing the science literacy abilities of junior high school students in a contextual and in-depth manner. The issue of low science literacy in Indonesia, where 53.60% of students are in the very low category, highlights the urgency of providing an evaluation instrument that can comprehensively represent scientific thinking abilities. This achievement is closely related to the lack of student training using international assessment-based testing instruments such as PISA during the learning process. The research method used was Research and Development (R&D) with a 4-D development model (Define, Design, Development, Dissemination). The instrument was developed based on four dimensions of science literacy (competence, context, knowledge, and cognitive level) within the PISA 2025 framework and covers topics in the science subject, namely electricity, waves, and magnetism. Content validation was conducted by content, instrument, and language experts, while empirical testing was carried out to evaluate the quality of the test items. The research results showed that the instrument had high content validity (CVI = 0.93; CVR = 0.8–1). The average validity of each item reached 0.60. The instrument showed good consistency in terms of reliability, as indicated by the Omega McDonald coefficient of 0.79 for the combination of essay and complex multiple-choice questions, and the Cronbach’s Alpha value of 0.68 for multiple-choice questions analysed separately. Most items were categorized as moderately difficult (72.73%) and had good discriminative power (63.63%). Additionally, the practicality value of 78.85% indicates that the instrument is easy to use in an educational context. Therefore, this instrument is suitable for use as a science literacy assessment tool aligned with the PISA 2025 framework and supports the development of higher-order thinking skills in national assessments.    Keywords: science literacy, instruments, assessment, PISA.

Abstract

Digital-based learning can mediate technical barriers and create a support system that enhances the effectiveness of education. This study aims to develop biology learning media, DigitalWIV-S, to enhance the inquiry skills and digital literacy of prospective science teachers. The development method follows Hannafin & Peck's model, which includes the phases of Needs Assessment, Design, Development, Implementation, and Evaluation. The research findings indicate that DigitalWIV-S, as a biology learning media, is deemed appropriate and received positive feedback from students. The evaluation of digital literacy is excellent across cognitive, affective, and conative aspects. Students' inquiry skills are very good in problem orientation and data collection; however, abilities in problem formulation, hypothesis structuring, data analysis, and summarizing are categorized as moderate among the students. The developed media for the PCR and Electrophoresis concepts help students understand these topics better, thereby enhancing their inquiry skills and digital literacy. Additionally, the media addresses the limitations of equipment and materials in modern biotechnology practicums.

Abstract

This meta-analysis aims to analyze the impact of Problem-Based Learning (PBL) on students’ science literacy in physics education. The study uses a descriptive quantitative method with a meta-analysis approach on 16 national journal articles that meet inclusion and exclusion criteria. Results indicate a significant average effect size of 1.72 (large category), with senior high school (effect size 1.95) having the most critical impact. In contrast, junior high and elementary schools have effect sizes of 0.77 and 0.48, respectively. Problem-based learning significantly impacts the Solar System, Heat & Temperature, and Global Warming. Furthermore, the implementation factor with the most significant and consistent impact is PBL combined with learning media, especially edugames and interactive simulations, with an average effect size of 1.76 (large category). These results suggest that PBL in physics education can significantly improve students’ science literacy, especially in higher education levels and with appropriate learning media.

Abstract

In PISA 2022, it was shown that Indonesian students' scores declined from 396 in 2018 to 383. This was evident in the 2022 National Assessment, where the science literacy ability at the high school level dropped by 4.59%. The low ability is mainly in optics, particularly optical instruments, indicating that students can only recognize the concept if they understand it. This study aims to determine the effect of inquiry-based learning on science literacy skills and Improvement in science literacy aspects. The research method used quasi-experimental with a nonequivalent control group design. The research population consisted of 199 students of grade XI at SMA Negeri 4 South Tangerang City, with a sample of 70 students: 35 students in class XI IPA 3 (experimental group) and 35 students in class XI IPA 4 (control group). The Mann-Whitney test results (Asymp Sig. 2-tailed < 0.05) showed a significant difference in science literacy skills between the experimental and control groups. The N-gain score indicated increased science literacy skills in the experimental group by 0.3 (medium category), while the control group was 0.10 (low category). Improvement occurred in the competence aspect by 0.33 and the knowledge aspect by 0.33 for the experimental group, while the control group in the competence aspect was 0.10 and the knowledge aspect was 0.13. Inquiry-based learning in this study has an effect and can improve students' science literacy skills.

Abstract

This study aimed to evaluate the effectiveness of Video-Based Laboratories (VBL) in enhancing critical thinking skills among state Islamic senior high school (Madrasah Aliyah Negeri) students in Hulu Sungai Tengah, Kalimantan Selatan, specifically in the context of rotational dynamics. Using a quasi-experimental design, we compared the performance of an experimental group that utilized VBL with a control group that followed traditional teaching methods. Data were collected through pretest and posttest assessments on critical thinking skills, and various statistical analyses were performed, including the paired samples t-test, Wilcoxon signed-rank test, and Mann-Whitney U test. The findings indicated significant improvements in critical thinking skills for both groups; however, the experimental group demonstrated substantially greater gains. This suggested that VBL, through interactive and hands-on learning methods, effectively enhanced critical thinking skills in physics education. The results underscored the potential of integrating VBL into physics curricula to foster deeper understanding and reflective reasoning. Future research should explore the long-term impacts of VBL and its application in diverse educational settings.
