Abstract

This study aims to develop students’ scientific argumentation through the implementation of socioscientific issues-based learning in the production of bioplastics from sugarcane bagasse (Saccharum officinarum). The method employed is pre-experimental with a one-shot case study design. The research subjects consisted of 36 eleventh-grade students from the Industrial Chemistry program at a vocational high school (SMK) in Cimahi City. The research instruments included student activity observation sheets, student worksheets, argumentation debates, and scientific argumentation tests. Students’ activities during the learning process showed excellent results, with an average score of 94. Meanwhile, their ability to complete the student worksheets achieved an average score of 98, both falling into the “very good” category. The majority of students’ oral argumentation was at level 2, which includes a claim supported by evidence without rebuttal. In contrast, the development of students’ written scientific argumentation after the implementation of socioscientific issues was at quality level 3, characterized by arguments that include weak rebuttals. These findings indicate that socioscientific issues-based learning can be effective in developing students’ scientific argumentation, although further instruction is needed to enhance students’ ability to present stronger, evidence-based rebuttals.

Abstract

Chemical literacy is an essential competency that includes understanding chemical concepts, critical thinking skills, and scientific-based decision-making in dealing with relevant social issues. Based on this urgency, this study aims to develop an e-module based on Socioscientific Issues (SSI) on addictive substances as an effort to develop chemical literacy. This study uses the R&D method with the ADDIE (Analyze, Design, Development, Implement, and Evaluation) model up to the Development stage to develop an e-module based on sociosatific issues. The research sample includes two material experts, one media expert, and 15 Chemistry Education students of UIN Sunan Gunung Djati Bandung as respondents for the acceptability test. Data were collected using validation sheets and questionnaires, then analyzed descriptively to determine the validity and feasibility of the e-module. The validation results of two material experts and one media expert showed an average score of the material aspect of 0.90, language 0.89, and appearance 0.87 (very valid). The student feasibility test showed a score of the material aspect of 92.22%, language 89.33%, and appearance 88.22% (very feasible). This e-module is feasible to be used as an innovative and contextual learning media and the basis for further development of the implementation and evaluation stages. This study presents a novelty in the form of an interactive e-module based on socio-scientific issues (SSI) for addictive substances material in Android format (.apk). This e-module is relevant for digital learning and is designed to improve students' chemical literacy by linking chemical concepts to real problems and training critical thinking and science-based decision making.

Abstract

Senior high school students often face difficulties in translating environmental knowledge into concrete environmental behaviors, and organic waste like pomegranate peels remains underutilized in chemistry learning. This study aims to analyze students' environmental literacy through project-based worksheets (PjBL) using pomegranate peel waste for lip balm production in colloid chemistry. A pre-experimental one-shot case study involved 18 eleventh-grade students in Bandung, Indonesia. Selected through a purposive sampling technique. Data were collected using project-based worksheets, assessment rubics for student work and environmental literacy instruments. Results showed worksheet scores at 89.5 (very good). Environmental literacy scores were: environmental knowledge 81.2 (very good), cognitive skills 89.3 (very good), environmental attitude 82.0 (very good), and environmental behavior 79.3 (good). The findings indicate that PjBL-based activities supported students' engagement with contextual colloid chemistry concepts. However, the lower environmental behavior score (79.3) compared to other domains indicates a gap requiring further intervention. Overall, PjBL shows promise for developing environmental literacy by integrating chemistry learning with waste utilization.
