The integration of Inquiry-Based Learning (IBL) and mobile technologies can transform science education, offering experimentation opportunities to students from budget-constrained schools. This study investigates the efficacy of smartphone-assisted experimentation (SAE) within IBL to enhance pre-service science teachers’ understanding of human physiology and presents a newly developed and validated rubric for assessing their scientific skills. Students (N = 286) from a Science and Mathematics Teacher Education Program participated in a summative IBL activity (“Investigating the Human Physiology”—iHPhys) where they designed experimental projects using smartphone applications to collect body sign data. The scoring rubric, assessing seven criteria including hypothesis formulation, methodological design, data presentation, and conclusion writing, was validated as substantial to almost perfect inter-rater reliability. Results reveal that students exhibited strong skills in hypothesis clarity, theoretical grounding, and experimental design, with a high degree of methodological innovation observed. However, challenges persisted in predictive reasoning and evidence-based conclusion writing. The students were strongly interested in inquiring about the cardiovascular and nervous systems. Correlational analyses suggest a positive relationship between project originality and overall academic performance. Thus, integrating SAE and IBL fosters critical scientific competencies, creativity, and epistemic cognition while democratizing access to scientific experimentation and engaging students in tech-savvy pedagogical practices.

This paper presents the development, implementation, and outcomes of the ELEVATE-US-UP (Engaging Learners through Exploration of Visionary Academic Thought and Empowerment in UnderServed and UnderPrivileged communities) teaching methodology, an equity-centered, culturally responsive pedagogical framework designed to enhance student engagement, academic performance, and science identity among underrepresented learners. This framework was piloted at Northern New Mexico College (NNMC), a Hispanic- and minority-serving rural institution. ELEVATE-US-UP reimagines science education as a dynamic, inquiry-driven, and contextually grounded process that embeds visionary scientific themes, community relevance, trauma-informed mentoring, and authentic assessment into everyday instruction. Drawing from culturally sustaining pedagogy, experiential learning, and action teaching, the methodology positions students not as passive recipients of content but as knowledge-holders and civic actors. Implemented across upper-level environmental science courses, the method produced measurable gains: class attendance rose from 67% to 93%, average final grades improved significantly, and over two-thirds of students reported a stronger science identity and a newfound confidence in their academic potential. Qualitative feedback highlighted increased perceptions of classroom inclusivity, community relevance, and instructor support. By centering on cultural context, student voice, and place-based application, the ELEVATE-US-UP framework offers a replicable and scalable model for educational transformation in underserved regions.

The time students spend on answering a test item (i.e., response time) and its relationship to performance can vary significantly from one item to another. Thus, using total or average response time across all items to predict overall test performance may lead to a loss of information, particularly with respect to within-person variability, which refers to fluctuations in a student’s standardized response times across different items. This study aims to demonstrate the predictive and explanatory value of including within-person variability in predicting and explaining students’ test scores. The data came from 13,829 fourth-grade students who completed the mathematics portion of Problem Solving and Inquiry (PSI) tasks in the 2019 Trends in International Mathematics and Science Study (TIMSS). In this assessment, students navigated through a sequence of interactive screens, each containing one or more related items, while response time was recorded at the screen level. This study used a profile analysis approach to show that students’ standardized response times—used as a practical approximation of item-level timing—varied substantially across screens, indicating within-person variability. We further decompose the predictive power of response time for overall test performance into pattern effect (the predictive power of within-person variability in response time) and level effect (the predictive power of the average response time). Results show that the pattern effect significantly outweighed the level effect, indicating that most of the predictive power of response time comes from within-person variability. Additionally, each screen response time had unique predictive power for performance, with the relationship varying in strength and direction. This finding suggests that fine-grained response time data can provide more information to infer the response processes of students in the test. Cross-validation and analyses across different achievement groups confirmed the consistency of results regarding the predictive and explanatory value of within-person variability. These findings offer implications for the design and administration of future educational assessments, highlighting the potential benefits of collecting and analyzing more fine-grained response time data as a predictor of test performance.

As global environmental challenges intensify, there is an increasing need to equip younger generations with the knowledge, values, and sense of responsibility necessary for a sustainable future. This study explores how environmental citizenship education (ECE), implemented through a nature-based learning program within a Nature and Science School (NSS) in Türkiye, was experienced and interpreted by primary school pupils in relation to their development of understanding of sustainability and environmental citizenship. NSSs, integrated into the formal education system by the Turkish Ministry of National Education, offer inquiry-driven and experiential learning in natural settings. The study took place in Talat Göktepe Grove, a biodiverse site including forest and marine ecosystems, where a four-month ECE program was conducted. A holistic single-case study design was employed, drawing on pupil diaries and semi-structured interviews. A total of 88 pupils engaged in structured outdoor activities addressing biodiversity, sustainability, and the climate crisis. Initially, pupils described environmental citizenship through individual actions. Over time, their perspectives expanded to include civic participation, environmental rights, and collective responsibility. Their reflections also revealed a more nuanced understanding of sustainability, encompassing concepts such as ecosystem balance, renewable energy, and environmental justice. The study provides insight into how nature-based education may support meaning-making around environmental citizenship and sustainability in early education. Full article

This study investigates how pre-service Earth science teachers used ChatGPT in designing lessons based on the 5E instructional model and what educational opportunities and challenges emerged. As generative AI tools gain traction in education, understanding their integration into science lesson planning is increasingly important. Eight pre-service teachers from a South Korean university participated in a four-week instructional design project. They developed 5E-aligned Earth science lessons while interacting with ChatGPT for idea generation, explanation, activity development, and assessment. Data sources included lesson plans, ChatGPT interaction logs, reflective journals, and interviews. Thematic analysis was used to examine instructional uses of AI and the adaptations required during the process. Findings showed that ChatGPT supported different phases of the 5E model—providing metaphors and analogies in Engage, activity ideas in Explore, draft explanations in Explain, task prompts in Elaborate, and assessment questions in Evaluate. However, participants frequently revised or rejected AI-generated content to match inquiry goals, student readiness, and curriculum standards. The study highlights the importance of pedagogical reasoning in AI-supported lesson design. It contributes to the growing literature on teacher education and AI by offering a phase-specific view of GenAI use and underscoring the instructional mediation needed for effective application.

At the beginning of the 21st century, rapid technological developments significantly impacted the field of education. As a result, university professors in recent years have been constantly searching and implementing teaching methods, such as blended learning, to increase the interest of their students and retain them in their courses. It is a matter of many academic discussions to create educational practices to reduce student dropout, especially in social sciences courses that are considered by students to be difficult subjects, such as accounting. The blended learning approach is based on constructivist theory and specifically on the Community of Inquiry model, where the educational experience of students is related to social, cognitive, and didactic presence, and it is orientated towards a more student-centred approach that maximises retention rates. The present study employs an exploratory blended-methods design. A questionnaire and individual interviews of students were used to collect data. The study was carried out in the context of an Advanced Financial Accounting course at a Greek university, through the implementation of an experiment with undergraduate students. Important findings include higher retention rates of undergraduate accounting students in the blended class compared to the traditional one, as the redesigning of content for the needs of blended learning, the incorporation of videos, the development of group work, and the good organisation of the course constitute the optimal mix for reducing student attrition.

Modeling is a fundamental scientific procedure for understanding nature, and it is also one of the basic strategies in inquiry-based science education. Among the various tools available for modeling, this article focuses on investigating a particular framework that uses embodiment to understand both macroscopic and microscopic phenomena. Within this approach, students actively engage as agents in the model and together build the final representation. For that, we present a specific methodology (the IBME approach) for inquiry-based modeling with embodiment. We specify the steps of the modeling approach, which were subsequently tested through instructional sequences based on this method with second-year students obtaining a degree in Primary Education at a public university. We analyzed the instructional sequences both quantitatively and descriptively. The quantitative analysis compares the results of an experimental group (n= 86) with a control group (n = 68) that does not work with inquiry-based modeling. Both groups address the same concepts, and at the end, they complete a questionnaire. The descriptive analysis discusses the details of the modeling process and the discussions that take place throughout the teaching sequences; on the other hand, it also summarizes the progress in the modeling process based on three qualitative parameters. The results obtained after implementing these sequences show significant differences compared to the control group. The descriptive analysis illustrates how students are able to reach the final model by inquiry, that is, through the discussion fostered by the modeling process itself, involving models of different levels of complexity.

This case study analyzes the academic emotions generated in a STEAM educational project developed in the controversial heritage of the Río Tinto and its surroundings. Twenty-five secondary education students participated in a didactic sequence that combined programming and the use of sensors for physicochemical data collection with inquiry- and modeling-based methodologies to address socio-scientific issues. Data were collected through open-ended questionnaires and field notebooks, allowing for an analysis of the emotions expressed at different stages of the project. The results show that epistemic emotions, such as curiosity and surprise, were predominant, highlighting the positive impact of experimental learning in this educational approach. Achievement emotions, such as pride and enjoyment, were linked to overcoming technological challenges, while thematic emotions, such as admiration and disgust, emerged from the heritage context, fostering critical reflection on environmental and historical issues. Negative emotions, such as frustration and anxiety, were also identified, mainly related to the technical difficulties and organizational challenges in group work. It is concluded that the proposed didactic sequence, by integrating the STEAM approach within a heritage context, mobilizes the epistemic emotions that were key in fostering analytical thinking and scientific exploration, while thematic emotions strengthened students’ connection with environmental and historical issues.

This work reviews the use of biodiesel synthesis experiments in science education, emphasising their potential for explicit nature of science (NOS) teaching. Through a literature review and experimental insights, it highlights how transesterification of waste cooking oil (WCO) with a basic catalyst can serve as an educational tool. While biodiesel reaction conditions are well-documented, this study presents them in a pedagogical context. Simple viscosity and density measurements illustrate empirical analysis, while a design of experiments (DoE) approach using a Hadamard matrix introduces systematic optimisation and scientific reasoning. By integrating biodiesel synthesis with explicit NOS instruction, this work provides educators with a framework to foster critical thinking and a deeper understanding of scientific inquiry. Additionally, this approach aligns with green chemistry principles and resource efficiency, reinforcing the broader relevance of sustainable chemistry. Full article

This study examines the environmental science curricula in secondary- and high-school education, as well as the prior knowledge of first-year university students regarding environmental pollution and sustainability. To this end, an inquiry-based methodology was implemented, focusing on the assessment of agricultural pollutants, with particular emphasis on the use of herbicides and pesticides. Through field studies, students developed analytical skills to evaluate crop conditions and understand the impact of agrochemicals on ecosystems. This study carried out in Spain, but may be transposable to other countries with similar characteristics. The results reveal significant variability in students’ prior knowledge, allowing for the identification of two distinct groups: those with no prior knowledge (G1) and those with a partial understanding of sustainability concepts (G2). This heterogeneity highlights the need for educational strategies that integrate scientific knowledge with environmental action, thereby strengthening ecological literacy. In this regard, this study underscores the importance of awareness programs that bridge theoretical concepts with practical applications in chemical risk management within agricultural production. Based on these findings, measures are proposed to mitigate the impact of pollutants on human health and the environment, including phytosanitary control strategies and the promotion of sustainable agricultural practices. In conclusion, this educational approach plays a key role in shaping citizens committed to sustainability and the transition toward responsible production and consumption models. Full article

This study examines students’ learning for action towards sustainability when addressing a local environmental problem related to mining through an Inquiry-Based Science Education (IBSE) approach. A total of 54 eighth-grade students (ages 13–15) from a rural middle school participated in this study. Data collection included written group productions and group interviews, which were analysed using inductive and deductive processes. The results revealed three levels of the students’ learning for action: “What” (problem identification), “Why” (reasons for action), and “How” (local action). All groups successfully identified the environmental problem, and 64% demonstrated understanding of the reasons for action, showing concern for future generations and environmental preservation. At the “How” level, 50% of the groups recognised the importance of local action, 34% actively planned and implemented actions, and 29% developed specific competences for action, including systemic thinking, argumentation, and communication skills. This research demonstrates that using the IBSE approach to address relevant local problems facilitates the development of action competences for sustainability. Digital technologies emerged as important tools for the students’ actions. The study also provides a framework for understanding and analysing students’ learning for action. Full article

This study investigated the impact of sustained, inquiry-based professional development (PD) on K-12 STEM educators’ instructional practices, with a particular focus on integrated mathematics and science teaching. As STEM education becomes increasingly vital in preparing students to address global challenges, educators face the challenge of adapting their teaching strategies to foster meaningful, engaging, and effective learning experiences. Inquiry-based learning (IBL) has emerged as a promising approach through its emphasis on student-driven exploration and collaborative learning. However, its effective implementation often requires targeted PD. This qualitative study examines the ConocoPhillips Applied Math Program (AMP!), a sustained teacher PD program focused on mathematics and science instruction, to investigate how it supported teachers’ shift toward inquiry-based practices. Semi-structured interviews with six past AMP! participants revealed that the program positively influenced teachers’ content knowledge, pedagogical strategies, and confidence, leading to better student engagement and achievement. This study also highlighted the importance of addressing the practical challenges of IBL implementation, such as teachers’ time constraints and resistance to adopting new pedagogical strategies. The findings emphasized the need for PD programs to prioritize adaptability and provide long-term support and content aligned with teachers’ immediate needs. Full article

This paper critiques traditional science assessments and advocates for reform-based learning that supports culturally diverse students, aligned with the Next Generation Science Standards (NGSS). While NGSS promotes collaborative, inquiry-driven practices, these are often difficult to assess through traditional high-stakes tests, which tend to reinforce systemic biases and marginalize students from non-dominant backgrounds. We examine the Lotions and Potions: Science through Black Hair Care curriculum, which uses a culturally sustaining approach, allowing students to respond flexibly in assessments. This approach enables students to participate fully in science practices without needing to conform to dominant cultural norms. Our findings highlight the benefits of culturally sustaining assessments that foster student voice, support diverse sense-making, and challenge exclusionary norms in science education. By positioning students as active knowledge builders who can draw on their cultural identities, such frameworks offer a more inclusive, empowering science learning experience. Future research will expand this model by refining pedagogical practices and curriculum design, particularly through culturally relevant applications of NGSS Science and Engineering Practices (SEPs) to further inclusivity in science and engineering education.

Student-centred learning requires a variety of approaches, such as inquiry-based learning and the tackling of authentic and problem-based learning activities, to make the teaching and learning process more meaningful and to encourage students to participate more actively in class. The inquiry approach enables students to investigate solutions to real problems, awakening their need to ask questions, design and conduct research, collect and analyse data, interpret results and present them in a structured way. This study investigates the influence of an inquiry-based science education (IBSE) module on the development of oral and written communication skills among 10th grade students. The study is set in a secondary school context and focuses on a problem-based learning approach centred around gases and dispersions. A total of 111 students participated in this one-group post-assessment qualitative study, where evaluation rubrics were applied to assess students’ written and oral communication, focusing on correctness, clarity and mastery of scientific language. The results showed that the majority of students performed well in both written and oral tasks, demonstrating improved scientific communication skills. This suggests that IBSE, particularly in the context of secondary education, can be an effective approach to fostering students’ abilities to communicate scientific concepts. The study has implications for enhancing pedagogical practices and encourages further research on the long-term effects of IBSE on student learning. Full article
