Abstract

For nearly two decades, augmented reality (AR) has found diverse applications in education, particularly in science education, where its efficacy has been supported by relevant theories and many empirical studies. However, previous studies have revealed the following research deficit: While AR technology appears to influence learning-related variables, at the time of this study only few research on the use of AR glasses in physics, a discipline for which this technology seems particularly promising in the context of laboratory experiments, has been found. Thus, the present study uses an experimental comparison group design to investigate the question of how the use of AR glasses in a physics laboratory experiment (compared to in a learning setting without AR) influences students’ motivation to learn, their cognitive load during the learning process and their learning achievement. The study (sample size N = 75) investigated the impact of AR glasses in a physics laboratory experiment on optical polarization. Results align with prior research, indicating heightened motivation among learners using AR applications. However, the absence of a significant difference in cognitive load between AR and non-AR learners was unexpected. Despite expectations based on spatial contiguity, learners with AR showed no advantage in learning achievement, challenging existing meta-analyses in physics education. These findings suggest a need to shift focus from surface features, like specific AR technology, to the content design of AR applications. Future studies should analyze the deep structure of AR applications, identifying features conducive to learning.

There are several specific digital tools now that have transformed the way science is taught. Correspondingly, teacher education programs have changed, and now they increasingly address the development of technology-related professional content knowledge (TPACK). Owing to the use of technology in specific domains of science teaching, there is an emergent need for domain-specific TPACK questionnaires. The present study investigates the development and application of a domain-specific TPACK questionnaire for teaching human biology using digital tools in a university-based teacher education program. A quasi-experimental between-subject design was applied for 13 weeks in the four study groups (n = 155). The intervention groups worked with digital tools in human biology, while the control groups participated without specific consideration of digital tools throughout the program. We succeeded in developing a questionnaire comprising seven reliable scales. The questionnaire development procedure described herein may be applicable to other science education disciplines. By the means of linear mixed modeling, we found that all students gained professional knowledge; however, treatment × time interactions revealed that belonging to the intervention group was the main driver of TPACK progression. Comparing the treatments, we found that at post-test, the intervention group reported higher levels of TPCK, TPK, and TCK, but not CK, PK, TK, and PCK. Sequential analyses of the longitudinal data highlighted that working with digital tools on a regular basis constitutes a TPACK boost effect. This study contributes to the literature on technology integration from the perspective of biology education, where specific tools that can be assessed using a domain-specific questionnaire are used.

The proliferation of generative artificial intelligence (GenAI) means we are witnessing transformative change in education. While GenAI offers exciting possibilities for personalised learning and innovative teaching methodologies, its potential for reinforcing biases and perpetuating stereotypes poses ethical and pedagogical concerns. This article aims to critically examine the images produced by the integration of DALL-E 3 and ChatGPT, focusing on representations of science classrooms and educators. Applying a capital lens, we analyse how these images portray forms of culture (embodied, objectified and institutionalised) and explore if these depictions align with, or contest, stereotypical representations of science education. The science classroom imagery showcased a variety of settings, from what the GenAI described as vintage to contemporary. Our findings reveal the presence of stereotypical elements associated with science educators, including white-lab coats, goggles and beakers. While the images often align with stereotypical views, they also introduce elements of diversity. This article highlights the importance for ongoing vigilance about issues of equity, representation, bias and transparency in GenAI artefacts. This study contributes to broader discourses about the impact of GenAI in reinforcing or dismantling stereotypes associated with science education.

Abstract

The Integrated Course Design (ICD), using Fink’s taxonomy of significant learning, popularly known as ICD/SL, is a handy way to create a better learning environment for students. It is a learner-centered approach with the desired end-product, but at the same time, it upgrades the teaching by improving the instructors’ delivery mechanism. Our goal of this study was to see whether ICD/SL affects students’ class participation and academic performance in the “Introduction to Bioinformatics” course offered at the Department of Biological Science, BITS Pilani, Pilani campus, India. Three class groups were chosen for this purpose: 2019–2020 (51 students), 2020–2021 (77 students), and 2021–2022 (72 students). The control group, 2019–2020, received no ICD/SL instruction; the remaining two groups, 2020–2021 and 2021–2022, received ICD/SL instruction that included revised learning goals based on Fink’s taxonomy and new teaching and evaluation activities. A Likert scale was utilized to assess students’ academic feedback using the Kruskal–Wallis test to determine the P-value. The findings showed that the treatment groups had higher class participation and academic performance in the summative assessment of final grades. In the experimental groups, the class participation was 23 to 27% higher compared to the control group. The absenteeism rate on the course decreased from 14% in 2019–2020 to 9% in 2020–2021 and 4% in 2021–2022. Also, in the treatment groups, 83 to 90% of students were in the High to Excellent category, compared to 74% in the control group. The failure rate of the course decreased from nearly 18 to 10% in 2021–2022 and only 6% in 2020–2021. There were significant differences between the treatment and control groups in class participation and academic performance (P < 0.05). This study has shown that the use of ICD/SL has the potential to improve students’ class participation and academic performance.

This study examined the impact of integrating virtual science inquiry activities with Predict-Observe-Explain (POE) teaching strategies on 5th graders’ understanding of science concepts and epistemic beliefs in science. A cohort of 80 5th graders (mean age of 12 years old, 40 boys and 40 girls) from a public primary school in North China took part in the research. The data collected encompassed pre-test and post-test results on understanding of science concepts and epistemic beliefs, along with students’ behavioral data during virtual science inquiry. The findings demonstrated that integrating virtual science inquiry activities with POE strategies increased students’ understanding of science concepts and epistemic beliefs in science. Furthermore, notable differences were found in observation time and inquiry strategy between high and low achievers, while significant distinctions in page time allocation and page navigation behavior were evident between boys and girls. The results provided empirical support for enhancing the implementation of virtual science inquiry activities in primary school science learning.

This study investigated how different learning tasks influence students’ collaborative interactions in immersive Virtual Reality (iVR). A set of chemistry learning activities was designed with iVR, and 35 pairs of undergraduate students went through the activities. Videos of students’ interactions were analysed to identify patterns in students’ physical, conceptual, and social interactions. When students were manipulating conceptually familiar virtual objects (several water molecules), they perceived the tasks as a simple extension of prior knowledge and did not attempt to explore the 3D visualisation much. They did not move around to take different perspectives, and conceptual discussions were brief. Their prior power relations (leader–follower) carried over in iVR environments. In contrast, when conceptually unfamiliar chemical structures (protein enzyme) were displayed, students perceived the tasks as complex, demanding a new mode of learning. They spontaneously moved around to explore and appreciate the 3D visualisation of iVR. Walking to different positions to observe the virtual objects from multiple angles, students engaged in more collaborative, exploratory conceptual discussions. As the perceived complexity of learning tasks or virtual objects triggers different collaborative interactions amongst students, careful considerations need to be placed on the design of iVR tasks to encourage productive collaborative learning.

Abstract

Informal science activities occurring at various non-traditional learning sites present a pivotal model for involving youths in the science learning process. The dynamic landscape of emerging technologies has prompted the exploration of innovative methodologies to bolster and refine informal science education. However, the expanse of this field and its attendant complexities has led to a lack of empirical evidence on the subject matter necessitating further research. This paper presents the findings of a systematic literature review, spanning the years 2017 to 2022, focusing on empirical inquiries into the deployment and impact of digital tools and technologies on the cognitive, affective, and behavioral dimensions of student learning. The investigation pertains specifically to unconstrained, extracurricular learning environments, encompassing science centers and museums and outdoor locations. A methodical search of renowned electronic databases, including ACM Digital Library, ERIC, Google Scholar, Sage, and Web of Science, supplemented by rigorous cross-referencing, yielded a corpus of seventeen (n = 17) relevant studies. These were subjected to a thorough qualitative content analysis. A diverse array of scientific concepts was found to have been investigated using hardware-based, software-based, or mixed approaches. Notably, augmented reality (AR) emerges as a preeminent focal point within the purview of digital interfaces explored by researchers. The synthesis of findings underscores the affirmative influence of digital tools and technologies on pivotal facets such as engagement, motivation, attitude towards science, and comprehension of scientific principles. In culmination, this study delineates prospective research focus for future studies in informal science education.

The Precipitating Change Project was a 5-year development, implementation, and research study of an innovative 4-week middle school curricular unit in computational weather forecasting that integrates students’ learning and use of meteorology and computational thinking (CT) concepts and practices. The project produced a list of CT skills and definitions that students use to predict the weather, CT assessment instruments, and a CT classroom observation protocol. Data was collected from 306 eighth grade (ages 13–14) students in rural indigenous communities in the Artic and urban and suburban Northeast communities in the USA. The project met its goal of producing an intentional instructional sequence that integrates disciplinary science and CT practices to increase students’ science knowledge and their ability to use CT skills and processes. The results indicate that teachers were able to use the curriculum to embed CT practices into the classroom. Students, in turn, had the opportunity to practice using these skills in class discussion as evidenced by the classroom observation data, and students’ science knowledge of CT content and practices significantly increased as evidenced by their performance on the weather content and CT skills pre- and post-assessments. While statistically significant gains in science knowledge and CT skills and practices were evident in all settings (urban, suburban, and rural indigenous communities), there were noticeable differences in gains in students’ CT skills and practices between the three settings and additional research is needed in a diversity of settings to understand this difference.
