The Effectiveness of QR Scanner Smartphone Integrated Ecosystem-Based Material Modules in Fostering Problem-Solving Skills

Abstract

This study aims to evaluate the effectiveness of using the QR Scanner integrated teaching module in ecosystem material in improving students' problem-solving skills. The experimental method was involved in this study with a pretest-posttest control group design. The research subjects consisted of 60 students divided into two groups, namely the experimental group and the control group, each consisting of 30 respondents. The experimental group received a QR scanner smartphone integrated ecosystem-based material modules, while the control group did not receive specific intervention. Pretest and posttest data were collected from both groups to evaluate changes in problem-solving skills after the intervention. Data collection was carried out through tests and questionnaires. Research data was analyzed through paired t-tests to compare pretest and posttest values in each group. The results showed that the experimental group experienced a significant increase in problem-solving skills (p less than 0.001). In contrast, the control group did not show a significant difference (p better than 0.05). Thus, the QR Scanner integrated teaching module in ecosystem materials improved students' problem-solving skills. This research provides important implications for developing technology-based learning approaches to improve the quality of learning and the application of concepts in students' daily
