ChatGPT becomes a prominent tool for students’ learning of science when students read its scientific texts. Students read to learn about climate change misinformation using ChatGPT, while they develop critical awareness of the content, linguistic features as well as nature of AI and science to comprehend these texts. In this exploratory study, we investigated students’ reading performance in comprehending two ChatGPT-generated socio-scientific texts, with one focusing on cognitive-epistemic aspects of climate science and another one focusing on social-institutional aspects of climate science. We theorized such reading of ChatGPT-generated outputs as encompassing the content-interpretation, genre-reasoning and epistemic-evaluation domains. Combining Rasch partial-credit model and qualitative analysis, we explored and investigated how a total of 117 junior secondary students (grades 8 to 9) read such texts. Moreover, we also examined how 55 students’ holistic reading of socio-scientific texts on climate change in a ChatGPT scenario changes after a reading-science intervention. Our findings indicate that the content-interpretation was the easiest while the epistemic-evaluation domains were the most difficult. Interestingly, after the reading-science intervention, many students developed their tentative view on nature of science when they evaluated ChatGPT’s claims; while a small increase in number of students discussed reliability and non-epistemic nature of AI when they evaluated ChatGPT’s claims in relation to climate change. The findings also drive a pedagogical model that improves students’ holistic reading of socio-scientific texts generated by ChatGPT.

Unlike in other countries, heredity and genetics appear first in Spanish science standards in secondary levels. However, some researchers have suggested the need of progressively introducing some basic genetic ideas already from primary education levels. In this context of no formal instruction in early stages, the objectives of our work were to characterize the incipient heredity model of primary school pupils and to evaluate its progression, to identify the most appropriate time to introduce these ideas. We designed a 12-item questionnaire referred to two constructs: (1) the difference between biologically inherited and environmental acquired traits and (2) the mechanism of inheritance. 535 primary school pupils (6–12 years; grades 1–6) took part in the study. In addition, 1–2 pupils per class were interviewed, totalling 30 interviewees. The results showed that pupils clearly identified physical resemblance as inheritable but had more difficulties in assessing physiological traits. Most pupils (84%) correctly identified that accidentally acquired traits were not transmitted to the descendance. However, only 32,2% of them use terms related to inheritance (77,1% of them in G4 – G6). Regarding the mechanism of inheritance, the idea that siblings express traits of both parents becomes more prevalent from grade 3, even suggesting the appearance of new traits or the mixture of previous ones. Older pupils accepted that a trait could skip a generation, although most of them were unable to explain the mechanism, that involves the idea of dominance/ recessiveness. These results allow identifying key leverage points for constructing the inheritance model at Primary levels.

This paper examines professional growth of a STEM teacher from the entrepreneurial frame. Using a personal narrative together with a STEM/science lesson package developed by the participant teacher, we unpack a teacher’s professional growth by interpreting her beliefs and actions using characteristics of entrepreneurial thinking. Our analysis and interpretations revealed that risk-taking forms of behaviour manifest as willingness to take calculated risks to make ‘cold’ calls to different organisations to request sharing or learning opportunities. The motivation to succeed stems from a belief that STEM education can improve the lives of students and that all students can learn. Passion for the discipline of STEM and personal beliefs to uplift students propel the teacher to persevere in her professional development despite busy schedules and conflicting demands of school and home. This study and its findings bring a fresh perspective to the idea of teacher agency from an entrepreneurial lens positioning teachers as self-empowered as compared to individuals who depended on the system to provide enablers for professional growth in the teaching profession. While self-empowerment to enact a curriculum is catalytic, teachers’ capacity for change is circumscribed by teachers’ capacity to act and accumulate practical knowledge. These entrepreneurial actions of successful STEM teachers could be used to facilitate teacher reflection on their professional journey. As the narrative approach sought to present an in-depth examination of the relationship between entrepreneurial thinking and teacher professional growth, the generalisability power of the assertions made is limited. The entrepreneurial thinking framework together with narratives from successful teachers enable teachers to locate where they are in their personal professional development and where they can aspire to move towards in their personal goal settings. Future research can examine teachers’ levels of entrepreneurial thinking and compare them against narratives of their professional growth to distil the behaviours that could lead to growth of entrepreneurial thinking. Curriculum leaders can also use the ideas of entrepreneurial thinking for professional growth to counsel and coach their team.

Building on previous research that demonstrates the association of youth experiences in afterschool science and higher science identities, this paper presents a network study of 421 middle school students that examines afterschool science participation, friendship ties, and science identities. Participation in afterschool science clubs is associated with higher science identity, but the mechanisms and order of causality are unclear. Youth form friendships inside and outside of school, and peers may influence participation in afterschool activities, as empirical research on friendships shows that they are associated with youth interests. These peer interactions also have the potential to shape identity development during adolescence. In this study, we explore associations among youth participation in afterschool science clubs, peer friendship groups, and science identity. We find that youth who participate in afterschool science clubs have higher science identities than those who do not participate. Additionally, having friends in afterschool science clubs is associated with higher science identity, even among students who report not participating in clubs themselves. Results suggest that afterschool science clubs support youth science identities, even beyond those who directly participate.

The prevailing portrayal of science and scientists within the public domain is a multifaceted mix of conventional stereotypes. Our study investigates these perceptions among Mexican children, analyzing 816 drawings and descriptions collected from fourth to seventh graders in rural and urban schools in Northwestern Mexico. Drawings were analyzed for the scientist’s appearance, location, and activity using mDAST/DAST, and each category was subcategorized for deeper compressive. The results confirm stereotypical depictions in all categories, however, girls draw more female scientists, mainly characterized by Caucasian features. Likewise, although stereotypical lab depictions persist, many drawings show alternative lab research and outdoor activities. Our study highlights the importance of promoting a diverse and inclusive image of scientists and their work, starting from an early age, using inclusive textbooks and effective pedagogical strategies.

A research model based on the presage–process–product theoretical framework was constructed to explore the relationship between STEM learning self-efficacy, perception of challenging learning environments, goal orientation (learning goal orientation and performance goal orientation), and entrepreneurial self-efficacy in students. Data were collected through a questionnaire survey of 110 STEM students who participated in a university–enterprise collaboration informal STEM education programme. The results, analyzed using partial least-squares structural equation modeling (PLS-SEM), indicated that both STEM learning self-efficacy and the perception of a challenging learning environment significantly positively affected learning and performance goal orientations. Furthermore, STEM learning self-efficacy had a direct positive effect on entrepreneurial self-efficacy. Importantly, learning goal orientation was found to mediate the relationship between the perception of a challenging learning environment and entrepreneurial self-efficacy. These findings highlight the critical role of targeted educational environments and goal-setting orientations in fostering entrepreneurial self-efficacy in STEM students, providing valuable insights for educators and policymakers in higher education.

Despite cultural differences, the Philippines–Japan partnership is developing an intentional teaching curriculum with parallel standards. However, disparities among their respective educational systems have prompted inequalities. As education plays a critical role in collaboration, we explored the Epistemic Goals (EGs) and Epistemic Practices (EPs) in the biology curriculum, with the research question: How do the epistemic goals and practices of the biology curriculum transmit knowledge and skills in the Philippines and Japan? Using an ethnographic design, we conducted two iterative explorations of EGs and EPs. First, we examined the curriculum policy to determine its EGs. Using the A-B-C-D protocol, we employed discourse analysis to evaluate knowledge and skills in the biology grade-level standards. Second, we examined the articulation of goals in classroom teaching practices. We conducted classroom immersion and observed classes to determine EPs and supported our observations through interviews, synthesizing the data using inductive content analysis. Our findings revealed that the Philippines’ EGs were to transmit factual knowledge enhanced by basic science skills, and their EPs were audio-visual materials, gamified instructions, guided inquiry, posing questions, and learning-by-doing. In comparison, Japan’s EGs were to provide a solid foundation of theoretical and metacognitive knowledge, integrated science skills, and positive attitudes. Its EPs involved cultivating lasting learning, observation, investigation, experimentation, collaborative discussion, and reflective thinking. Our study makes a meaningful contribution by shedding light on crucial ideologies and cultural identities embedded in Biology curricula and teaching traditions.

Declining enrolments in senior secondary science have heightened concerns for meeting the demands for more STEM-qualified workers and a scientifically literate society. Students' attitudes to science are formed during schooling, particularly in adolescence when they are exposed to a variety of science topics. Students’ perceptions of their ability in science and their subjective task values are well established as predictors of their likelihood of engaging with and continuing their study of science. However, the role of classroom-based social support in supporting ability perceptions and task values is less well understood. In this study, we examined relationships between adolescents’ perceived classroom-based social support, task values, and self-efficacy, and how these perceptions and attitudes predicted adolescents’ intentions to study the three major science subjects (biology, chemistry, and physics) in senior high school. Participants were 475 adolescents in Grades 8 to 10 recruited from six schools in Sydney, Australia. Structural equation modelling was employed to test the hypothesised model in which social support from science teachers and peers predicted intended science subject selections through science self-efficacy, intrinsic valuing of science, and utility value of science. Results indicate that science teacher and peer support were not directly related to adolescents’ intentions to study senior science subjects. Instead, they were indirectly related via their positive relationship with science self-efficacy and task values. Utility value was the strongest predictor of adolescents’ intentions to study biology, chemistry, and physics, while self-efficacy and intrinsic value also predicted adolescents’ intentions to study chemistry. These results suggest that classroom-based social supports are important for supporting adolescents’ attitudes towards science, and that science utility value interventions may be useful in efforts to improve enrolments in senior science subjects.
