Abstract

This study explores the joint influence of sociocultural understanding, science literacy, psychomotor skills, and learning approach on the development of students’ character along with their conceptual understanding of environmental change. Using a quantitative explanatory design, this study utilized Structural Equation Modeling (SEM) to analyze data from a total of 837 high school students in South Sulawesi, Indonesia. The findings of this study show that sociocultural understanding significantly influences students’ character development. However, it does not appear to influence conceptual understanding. Meanwhile, science literacy has a dominant influence on both sociocultural understanding and character development. Learning approach significantly influences character development but negatively impacts conceptual understanding. These findings underscore the importance of integrative education, which incorporates cultural responsiveness, science literacy, and experiential learning to holistically enhance ethical values, cognitive skills, and practical competence. This study provides new insights into sustainable teaching strategies, highlighting their role in guiding individuals to be responsible for environmental change and scientifically literate.

Abstract

Background: Problem-Based Learning (PBL) promotes higher-order thinking, but in cell biology its implementation often produces cognitive overload because students must coordinate abstract organelle structures, invisible intracellular processes, and interconnected metabolic pathways across multiple representations. Existing studies rarely integrate structured problem design and task sequencing to address these specific cognitive demands. This study addressed that gap by combining the 3C3R and 4C/ID frameworks within a PBL environment. Objective: This study aimed to develop and evaluate an integrated PBL-3C3R-4C/ID instructional model for cell biology in terms of validity, practicality, and effectiveness in managing students’ cognitive load. Methods: Using a Research and Development approach based on Hannafin and Peck, followed by a pretest-posttest control group design, the study involved 231 secondary school students. Cognitive load was measured through a multidimensional scale covering intrinsic, extraneous, and germane load. Data were analyzed using descriptive statistics and paired t-tests. Results: The model demonstrated high validity and strong reliability (α = 0.91). Post-intervention results showed significant improvement in learning outcomes, accompanied by reduced extraneous load and increased germane load. Conclusion: Integrating 3C3R and 4C/ID within PBL offers a theoretically grounded and empirically supported approach for teaching complex cell biology while managing students’ working memory demands more effectively.

Abstract

Background: Although STEM plays a critical role in biology education, a persistent disconnect exists between Indonesian teachers' strategic knowledge and their pedagogical practices. Objectives: This study sought to examine biology teachers’ perceptions of STEM, their knowledge of implementation strategies, and their understanding of implementation challenges. Additionally, it assessed the gap between teachers’ strategic knowledge and classroom practices. Methods: A mixed-methods design employing a sequential explanatory approach was utilised, consisting of a quantitative survey of 94 high school biology teachers (purposive sampling), followed by semi-structured interviews. The 16-item instrument demonstrated reliability (Cronbach's α = 0.878). Quantitative data were analysed descriptively (means and standard deviations), while qualitative data were analysed thematically, utilising triangulation and member checking. Results: Teachers exhibited high knowledge of STEM implementation strategies (M = 4.22 ± 0.75), but reported moderate barriers to implementation (M = 3.62 ± 0.78), moderate self-confidence (≈ M = 3.16), and moderate to high STEM teaching practices (M = 3.52 ± 0.77). Interviews revealed that STEM was frequently defined as simple technology use; however, components such as engineering design, modelling, meaningful mathematics, and performance assessment were inconsistently applied, largely due to limitations in training, time, facilities, and access to technology. Conclusion: Practice-based professional development, a unified STEM framework for biology, and school support–including project time blocks and low-cost tools–are essential for translating knowledge into consistent classroom practice.

Abstract

Background-Problem-solving skill is one of the essential 21st-century competencies that should be enhanced through contextual learning. Disaster mitigation learning in schools generally remains theoretical and has not fully encouraged students’ active participation in developing higher-order thinking skills. Objectives-This study is aim to develop a disaster mitigation board game integrating animal and plant behavioral indicators to examine its validity, practicality, and effectiveness in enhancing students’ problem solving skills. Method-This research and development employed the ADDIE model, consist of analyze, design, development, implement, and evaluate. The research subjects were 21 students of tenth-grade high school. Data were collected through media and material expert validation sheets, student response questionnaire, and problem-solving skill tests. Data were analyzed using descriptive quantitative analysis, N-Gain calculation, and paired sample t-test. Results-The validation results showed that the media obtained a score of 95% from media experts and 97% from material experts, categorized as very valid. Student responses indicated a practicality level of 92.33% categorized as very practical. The N-Gain value of 0.704 was classified as high effectiveness, and the paired sample t-test results revealed a significant improvement in students’ problem-solving skills (0.00, p<0.05) and Cohen’s d 2.65.  Conclusions-The disaster mitigation board game indicated potential effectiveness in improving students’ understanding of adaptive behavior in living organisms within disaster context, as well as fostering critical and collaborative thinking skill. Further research is suggested to use massive field trial thus develop digital version to increase interactivity and accessibility.

Abstract

Indonesian people have long used wild ginger (Zingiber zerumbet) as an ingredient in traditional medicine and rituals. Its rhizomes have been shown to contain several bioactive compounds with antioxidant and antibiotic activity that are believed to be able to treat typhoid fever. This study aims to evaluate the antioxidant and antibacterial activities of Z. zerumbet extract using ethanol and methanol as solvents. Z. zerumbet extract was purified, LC-MS tests were conducted to identify active compounds, phenolic and flavonoid content tests were conducted using colorimetry methods, DPPH tests were conducted to measure antioxidant activity, and Minimum Inhibitory Concentrations (MIC) and Minimum Bactericidal Concentrations (MBC) tests were conducted to measure antibacterial activity. LC-MS analysis proved that Z. zerumbet contains active compounds such as flavonoids with their derivatives, such as kaempferol, quercetin, myricetin, etc. Z. zerumbet with ethanol solvent had stronger antioxidant activity (IC₅₀ = 125.97 μg/mL) than methanol solvent (IC₅₀ = 404.91 μg/mL). In contrast, ethanol solvent had lower antibacterial activity than methanol solvent. The findings of this study show that the antioxidant and antibacterial activities of Z. zerumbet depend on the solvent used and can be used as an alternative natural remedy for treating typhoid-related infections. This research supports the three goals of the SDGs by strengthening public knowledge of Z. zerumbet as a traditional medicinal ingredient, thereby improving disease control and the quality of public health through natural medicinal ingredients.
