Abstract

This research aims to analyze the 2013 Curriculum Middle School Science textbooks published by the Ministry of Education and Culture and Erlangga publications used in Indonesia when compared with the Lower Secondary Science Matters textbooks used in science learning in Singapore in terms of the aspect of scientific argumentation on the topic of heat. This research is qualitative research analyzed using the constant comparison method. The data analysis process was carried out through five stages, namely reduction, organizing, categorization, synthesis and developing working hypotheses. After the organizing stage, a data validity test is carried out using credibility, transferability, anteriority and confirmability techniques. The results of the research found that there were differences in the scientific argumentation aspects of the three textbooks, namely the majority of the Lower Secondary Science Matters textbooks were at level 3, while the majority in the 2013 Curriculum Middle School Science textbooks published by the Ministry of Education and Culture and those published by Erlangga were at level 2. In the Curriculum Science textbooks The 2013 edition of the Ministry of Education and Culture from Indonesia provides more statements accompanied by supporting sentences to prove the truth in the form of data, experiments, observations in daily life, and pictures that illustrate a situation, whereas the Lower Secondary Science Matters textbook provides more statements ( claim) which is accompanied by supporting sentences to prove its truth in the form of data, experiments, observations in daily life, and pictures that illustrate a situation (data), then reinforced by sentences that connect them (warrant).                                                                                        Keywords: scientific argumentation, Toulmin's Argument Pattern (TAP), science textbook.

Abstract

This study aimed to design and evaluate a local wisdom–based entrepreneurship course model to enhance the entrepreneurial competencies of pre-service science teachers. The research followed the ADDIE (Analyze, Design, Develop, Implement, and Evaluate) instructional design framework and employed the Delphi and Fuzzy Delphi methods for expert validation involving ten specialists in science and entrepreneurship education. A true experimental design using a posttest-only control group was conducted with 62 participants enrolled in an entrepreneurship course at a university in Central Java, Indonesia. Data were analyzed through descriptive statistics, the Shapiro–Wilk normality test, independent sample t-tests, and Cohen’s d to determine the effect size. The results demonstrated that the developed model achieved high validity across all instructional stages (DV > 0.7; d < 0.2). Empirical findings indicated that the experimental group exhibited significantly higher gains in entrepreneurial skills than the control group (p < 0.05), with a large effect size (Cohen’s d = 2.54). The model effectively strengthened students’ risk-taking abilities, opportunity recognition, self-efficacy, emotional intelligence, and innovative thinking. These findings underscore that integrating local wisdom into entrepreneurship education fosters contextualized learning experiences and promotes sustainable entrepreneurial behavior among future science educators. The proposed model provides a practical framework for higher education institutions to develop entrepreneurial competencies while preserving and utilizing local cultural values.Keywords: entrepreneurship education; local potential; pre-service science teachers; entrepreneurial skills; fuzzy
