Enhancing Science Learning Outcomes through Problem-Based Learning with Edform Worksheets

Abstract

Low learning outcomes in biology are often linked to teacher-centered instructional approaches and the lack of interactive digital learning media. This study aims to investigate the effectiveness of implementing the Problem-Based Learning (PBL) model assisted by Edform-based electronic student worksheets (E-LKPD) in improving students’ learning outcomes. The research was conducted as Classroom Action Research (CAR) involving 34 students of class XI K at SMA Negeri 2 Palu during the even semester of the 2024/2025 academic year. The study consisted of two cycles, each comprising four stages: planning, implementation, observation, and reflection. Data were collected through learning outcome tests, observation sheets of teacher and student activities, and student response questionnaires. Quantitative data were analyzed descriptively, while qualitative data were obtained through classroom observations and student responses. The results showed that the average student score in Cycle I was 64.92%, categorized as moderate, and increased to 82.53% in Cycle II, categorized as high. This improvement of 27.12% indicates that the implementation of PBL assisted by Edform-based E-LKPD is effective in enhancing students’ biology learning outcomes. In addition, students demonstrated more active participation, improved collaboration, and greater motivation during learning activities. Therefore, PBL supported by interactive digital worksheets can be considered an alternative instructional strategy to promote meaningful and engaging biology learning.
