Bridging the Gap among Knowledge, Attitudes, and Behaviors toward Sustainable Development through I-STEM-PBL-ESD

Abstract

Bridging the gap among knowledge, attitudes, and behaviors (KAB) is essential for achieving sustainable development (SD). This study examined changes in students' KAB, before and after the implementation of Integrated Science, Technology, Engineering, and Mathematics - Problem-Based Learning - Education for Sustainable Development (I-STEM-PBL-ESD) modules. Employing a quantitative descriptive survey research design, the study targeted Filipino Grade 11 STEM students (n = 38) enrolled in General Biology 1. Data were collected using the OSISDeP (pretest and posttest) tool to measure KAB, and the I-STEM-PBL-ESD modules as learning interventions. The results revealed significant improvements in students' KAB, demonstrating enhanced understanding of SD, more positive attitudes toward its socio-economic and environmental aspects, and increased engagement in behaviors supportive of sustainability. Notably, the study observed a close alignment between knowledge and attitudes after the intervention, while the relationship between knowledge and behaviors remained relatively stable. These findings highlight the effectiveness of active learning methods, such as I-STEM-PBL-ESD, in shaping students' perspectives and emphasize the need for further progress through practical community engagement to bridge the gap between knowledge and behaviors, ultimately promoting sustainable practices.
