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.

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

The PRISMA-E’xi learning model integrates multiple-representation approaches, the engineering design process (STEM), and strategies designed to enhance students’ creative problem-solving skills. This study aimed to evaluate the model’s practicality through an initial implementation in senior high school physics instruction. A quantitative descriptive design was employed at the developmental research limited-trial stage, involving one tenth-grade class at SMA Gajah Mada Bandar Lampung across six instructional sessions. Data were collected through validated observation sheets assessing model implementation, teacher performance, and student activities, as well as questionnaires measuring teacher and student responses. The findings demonstrated high practicality, with implementation scoring 91.17%, teacher performance 92.31%, and student activity 88.33%, all categorized as “Excellent.” Teacher and student responses were overwhelmingly positive, with agreement levels of 98.00% and 98.95%, respectively. Although minor technical refinements were suggested, the core structure of the model remained intact and ready for broader deployment. Overall, the results indicate that PRISMA-E’xi is highly implementable, well-received, and holds strong potential to enhance student engagement and higher-order thinking in physics learning while providing teachers with a structured framework that supports 21st-century skills development.

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.
