Abstract

The research focuses on the development and implementation of the EcoViber application to address plastic waste management in school environments, specifically at SDN Perdopo 02. The study aims to tackle the issue of plastic waste accumulation through technological solutions, enhancing environmental awareness and operational efficiency. The application employs the waterfall method for development and features data collection, visualization, and educational tools to promote transparency and accountability. Comprehensive observations and interviews with seven teachers revealed significant improvements in waste management, with approximately 54.95 kg of plastic waste collected from January to April 2024. The findings highlight the practical implications of EcoViber in fostering a culture of environmental stewardship among school stakeholders. Despite its success, the study acknowledges potential biases in data reporting and the limited generalizability of results due to the focus on a single school. Future research should explore diverse settings and refine methodologies to enhance the scalability and long-term impact of EcoViber. Overall, the study demonstrates EcoViber's value as an innovative and effective solution for sustainable plastic waste management in educational settings.

Abstract

21st-century skills, such as critical thinking and digital literacy, have become essential in modern learning. This study aims to examine the impact of the Problem Based Learning (PBL) model on students' critical thinking and digital literacy skills in the topic of atmospheric dynamics at Sekolah Indonesia Kota Kinabalu, Sabah-Malaysia. The research design used a quasi-experimental approach with a nonequivalent control group design. The sample consisted of 34 students in the experimental group and 31 students in the control group. The experimental class implemented the Problem Based Learning (PBL) model, while the control class used conventional methods. The results showed a significant improvement in both variables in the experimental group, with N-Gain Scores categorized as effective. Problem Based Learning (PBL) helps students understand scientific concepts in-depth, identify real-world problems, and develop creative, technology-based solutions. These findings prove that Problem Based Learning (PBL) is an innovative teaching method that is effective in enhancing students' competencies, especially in preparing them to face global challenges and the digital era.

Abstract

This study aims to determine the effect of the Scratch-assisted Problem-Based Learning (PBL) model on the critical thinking skills of seventh-grade students in Informatics subject, specifically on computational artifact development. The research employed a quantitative approach with a quasi-experimental design, using a pretest-posttest control group. The research sample consisted of two classes: an experimental class that implemented the Scratch-assisted PBL model, and a control class that used a conventional learning model. The critical thinking assessment instrument was developed based on five indicators from Facione: interpretation, analysis, evaluation, inference, and explanation. Data were analyzed using an independent samples t-test to determine the significance of the differences between the groups. The results of the independent samples t-test showed a statistically significant difference between the experimental and control groups (t(38) = 3.45, p = 0.004). The mean posttest score of the experimental group increased significantly from 62.4 to 83.6, with a large effect size (Cohen's d) of 1.24. The research sample consisted of 40 seventh-grade students divided into two groups. The inference and explanation indicators showed the highest improvement. In addition to the score improvement, project-based learning with Scratch also facilitated 21st-century skills such as collaboration, problem-solving, and student digital agency. The integration of Scratch provided space for computational thinking, solution visualization, and self-reflection. This study recommends the use of digital-based PBL models as an innovative learning strategy aligned with the Merdeka Curriculum.
