Abstract

Indonesia’s position as the world’s second-largest contributor to plastic waste reflects deeply rooted patterns of unsustainable consumption. Addressing this critical issue requires innovative educational strategies to cultivate environmental responsibility and creative problem-solving in future teachers. This study examines how a guided research-based learning (GRBL) model can transform the perceptions of prospective primary school teachers regarding plastic waste management—shifting from conventional 3R (Reduce, Reuse, Recycle) actions to designing environmentally friendly bioplastics. Employing a one-shot case study design, the research was carried out over one semester in a science education course involving 214 fifth-semester students enrolled in a primary teacher education programme. They were divided into 54 groups. Data were collected through observation sheets, student worksheets, and creativity assessment rubrics. The findings suggest that GRBL prompted students to critically engage with sustainability issues by exploring the biodegradability of various natural materials. Most participants selected starch-based substances due to their accessibility and assumed ecological benefits. However, the resulting bioplastic products predominantly exhibited characteristics of modification and imitation rather than originality or innovation. The proportion of students proposing plastic from organic materials increased significantly from 22.2% to 66.7%, with 27.8% suggesting edible straw ideas. While these developments are promising, the ideas lacked originality and were limited to modifications and imitations. This indicates that while GRBL broadened students’ views on waste solutions, their creative outputs remain limited by insufficient scientific exploration and design experience. The study concludes that GRBL has strong potential to foster sustainability-oriented thinking in teacher education, especially when paired with deeper inquiry and iterative practice. These findings highlight the need for science teacher education to embed structured, hands-on research experiences that connect scientific knowledge with real-world environmental issues, preparing future educators to promote both creativity and ecological awareness in the classroom.

Abstract

Abstract Vocational education in machining engineering often continues to emphasize the mastery of practical procedures, while students’ critical thinking skills in analysing problems, evaluating alternatives, and making technical decisions have not been optimally developed. This study aimed to examine the effectiveness of the Inquiry-Creative Learning model in improving students’ critical thinking skills and to identify the supporting and inhibiting factors in its implementation. The study employed a mixed-methods approach with an explanatory sequential design. The quantitative phase used a quasi-experimental pretest-posttest control group design involving 63 eleventh-grade students in the Machining Engineering Program, consisting of 30 students in the experimental group and 33 students in the control group. The qualitative phase involved six students from the experimental group and two mechanical engineering teachers through semi-structured interviews and observations. The test instrument measured four indicators of critical thinking, namely analysis, inference, evaluation, and decision-making. The data were analysed using descriptive statistics, gain, N-gain, ANOVA, Mann-Whitney U test, eta squared, and thematic analysis. The results showed that the mean score of the experimental group increased from 36.00 to 71.20, while that of the control group increased from 37.58 to 47.36. The N-gain score of the experimental group was 0.539, which was in the moderate category, whereas that of the control group was 0.145, which was in the low category. ANOVA showed significant differences in posttest scores (F = 157.207; p < 0.001; η² = 0.720), gain scores (F = 110.140; p < 0.001; η² = 0.644), and N-gain scores (F = 221.174; p < 0.001; η² = 0.784), which were further supported by the Mann-Whitney U test. The qualitative data revealed that group discussion, real problems, hands-on practice, availability of tools, and teacher readiness supported students’ critical thinking, whereas limited time, low self-confidence, and student passivity served as inhibiting factors. This study concludes that Inquiry-Creative Learning is effective in improving students’ critical thinking skills and has implications for vocational learning that is investigative, reflective, contextual, authentic, and collaborative.

Abstract

This study aimed to evaluate the effectiveness of a sciencepreneurship-based community empowerment model in developing appropriate technology to improve the entrepreneurial intention (EI) of rural communities. The study was conducted in Krayan Jaya Village, Long Ikis District, Paser Regency, East Kalimantan, involving 40 participants divided into two groups: an appropriate technology group for producing tote bags made from spunbond fabric (Group A) and an appropriate technology group for developing a solar-powered water pump (Group B). This study employed a mixed-methods approach with an explanatory sequential design. The quantitative phase used a quasi-experimental multi-group pretest-posttest design, while the qualitative phase involved observation and semi-structured interviews. Entrepreneurial intention was measured using a 20-item Likert-scale questionnaire covering entrepreneurial orientation, internal motivation, risk-taking courage, and self-perception as a prospective entrepreneur. The data were analysed using descriptive statistics, assumption testing, the Wilcoxon signed-rank test, N-gain, ANCOVA, and thematic analysis. The results showed that the mean EI score of Group A increased from 50.80 to 78.45, with an N-gain of 0.56, while that of Group B increased from 52.00 to 74.50, with an N-gain of 0.48. The Wilcoxon test indicated significant improvement in both groups (p < 0.001). ANCOVA showed a significant difference in effectiveness between the groups after controlling for pretest scores (F = 7.156; p = 0.011; partial eta squared = 0.162), with the adjusted mean of Group A higher than that of Group B. The qualitative data revealed that involvement in appropriate technology development, institutional support, and business opportunities strengthened EI, whereas limited capital, fear of failure, technical complexity, and marketing challenges acted as barriers. This model is relevant for participatory, contextual, and sustainable rural community empowerment, particularly when supported more systematically by village-owned enterprises and local facilitators.
