Abstract

This study aims to produce differentiated student worksheets that are valid, practical, and effective in improving students' critical thinking skills. The research and development (R&D) design was conducted using the 4-D model, which consists of four steps: define, design, develop, and disseminate. The research subjects were 15 students in a small-scale trial and 66 students in a large-scale trial, all from class XI of SMA Negeri 1 Seputih Surabaya with cluster random sampling. The trial design used by the researcher was a non-equivalent control group design. The instruments used were needs analysis questionnaires, validity questionnaires, practicality questionnaires, learning implementation observation sheets, and pretest-posttest of critical thinking skills. Data analysis techniques for validity and practicality use descriptive percentage analysis, while data analysis for effectiveness uses statistical analysis (independent sample t-test, paired sample t-test and one-way anova). The results of the development research indicate that differentiated student worksheets are highly valid (94%); differentiated student worksheets are practical for improving students' critical thinking skills in terms of learning implementation; differentiated student worksheets were effective in improving students' critical thinking skills with a large effect size (0.99). The conclusion is that differentiated worksheets on the human digestive system have been developed that can improve students' critical thinking skills.

Abstract

Background: Critical thinking is an important skill because it involves reasoning and logic in problem solving efforts. Although it is important, it turns out that students’ critical thinking skills are currently still low. Aims: This study aims to describe the practicality and effectiveness of e-worksheets based on Differentiated PjBL-STEM to improve critical thinking skills. Methods: This research is a Research and Development that refers to the Borg and Gall model. The population is all grade IX students at one of the junior high schools in Tanjung Bintang District. Research instruments were questionnaires for the needs of educators and students, questionnaires for validating e-worksheets by experts, questionnaires for responding educators and students, pretest-posttest, critical thinking skills data analysis techniques using t-test. Result: The validation results of e-worksheets for the suitability of content, attractiveness, and readability obtained an average of 88.35%, meaning that e-worksheets is valid, while the educator’s response was 98.29%, the average student response for the attractiveness and readability aspects was 96.11%, meaning that e-worksheets is practically. The results of the t-test sig.2 tailed value of 0.000 mean that the average critical thinking skills in the experimental class are higher than those in the control class. This is supported by an effect size of 1.29 which is categorized as “large”. Conclusion: Differentiated PjBL-STEM-based e-worksheets effectively improve students critical thinking skills with a significant impact on tolerance of differences in student learning readiness. Therefore, differentiated PjBL-STEM learning is important to implement in schools, especially project-based learning that is relevant to the real world.

Abstract

This study investigates the effectiveness of the PRISMA-E’xi learning model—an instructional innovation that integrates a multi-representation approach with the Engineering Design Process (EDP) in a STEM framework—to enhance senior high school students’ creative problem-solving (CPS) skills in physics. Employing a quantitative quasi-experimental design with a nonequivalent control group, the research involved 350 students from five schools representing rural, suburban, and urban regions. Students in the experimental group (n = 175) received instruction using PRISMA-E’xi, while those in the control group (n = 175) experienced conventional teaching. CPS ability was assessed through pre- and posttests aligned with six indicators: objective finding, fact finding, problem finding, idea finding, solution finding, and acceptance finding. Data were analyzed using independent t-tests, effect size (Cohen’s d), one-way ANOVA, and MANOVA with prerequisite tests for normality and homogeneity. Results revealed a highly significant improvement in CPS for the experimental group (t(342) = 17.8, p < 0.001) with a large effect size (d = 1.92). One-way ANOVA indicated no significant differences in n-gain across regions (p = 0.707), and MANOVA confirmed a strong multivariate effect of the learning model (Pillai’s Trace = 0.5027, p < 0.001) on all CPS indicators without regional interaction effects. Each instructional syntax of PRISMA-E’xi—problem exploration, representation structuring, investigative reasoning, scientific modelling, model assessment, and adaptive reflection—was found to foster specific CPS indicators, supporting critical and creative thinking as well as adaptive reasoning. Guided reflection, multi-representation analysis, and iterative solution evaluation promoted deep conceptual understanding and transferable problem-solving skills. The findings demonstrate that PRISMA-E’xi is an effective, flexible, and equitable model for improving students’ creative problem solving in physics, independent of geographic context. Despite limitations related to the quasi-experimental design, limited duration, and sample scope, the study provides robust empirical evidence that PRISMA-E’xi can serve as a scalable and innovative framework for 21st-century competency-based science education. Future research should employ randomized or longitudinal designs and explore cross-disciplinary applications to strengthen external validity and long-term impact assessment.

Abstract

Creative thinking skills are widely discussed in science education research, yet their conceptualization, pedagogical treatment, and measurement still show methodological diversity. This study systematically synthesizes recent studies on creative thinking skills in science education, focusing on learning strategies, learning media, and assessment instruments. A systematic literature review (SLR) using the PRISMA framework was conducted on 23 Scopus-indexed publications from 2019–2022. The results indicate that most studies position creative thinking skills as a learning outcome embedded in instructional innovation rather than as an independent construct. STEM-oriented learning, technology-assisted learning, problem-based learning, and inquiry-based learning are the most frequently explored contexts. However, the literature is dominated by qualitative and descriptive research, with limited comparative or experimental evidence. Variation in definitions and measurements also persists, often overlapping with related constructs such as critical thinking. Overall, this review reveals rich pedagogical innovation but limited methodological consistency and analytical rigor. The findings highlight the need for clearer construct boundaries, more robust research designs, and better alignment between learning strategies and validated instruments. This review contributes to mapping research patterns and identifying gaps for future empirical studies in creative thinking skills in science education

Abstract

This study aims to describe visual representation-based android learning media to improve students' representation abilities based on the views of teachers and students. This research involved 39 science teachers and 181 junior high school students in Lampung province. The method used in this study is a mixed method with an explanatory sequential design in order to obtain quantitative and qualitative data through questionnaires and interviews. The results of the study show that teachers and students have a positive perception of the development of visual representation-based android learning media. This study found the fact that there were several factors that caused teachers not to pay attention to students' representation abilities. The teacher believes that the use of learning media can train students' representation abilities and have an impact on increasing student representation abilities.
