The Many-Facet Rasch model is frequently used to analyse and minimize disparities in rater (judge) severity in performance evaluations, in which raters assign scores to test-takers' performances. In this research, the aim of the present study was to analyse science teacher candidates' laboratory activities by using the Many-facet Rasch model.…

The declining interest in science learning, along with students' perception that science is irrelevant to their daily lives, has been identified as a significant issue. This research aimed to help students connect abstract scientific concepts with their personal and everyday experiences. To achieve this, the research utilized the metaphysical…

Design activities are gaining interest as rich contexts for learning science, technology, engineering, and mathematics (STEM) subjects. STEM teachers may find this challenging however, as designing requires support that they are not used to providing. In a subject like chemistry, teachers would have to balance creativity and responsibility for the…

Professional development (PD) can support science teachers to learn about instructional reforms, but more work needs to be done on broadening our understanding of how specific PD activities support teacher learning. One understudied PD activity is the "student hat": when teachers engage in student learning activities while considering…

Taking on an agentic perspective, this study employed a digital ethnographic approach to examine a science teacher's emotional experiences in an online graduate science education course during the COVID-19 pandemic. Veronika, the teacher, revealed her feelings of grievance and loss to the graduate course cohort at the advent of large-scale school…

This study aims to investigate the situation of science teachers regarding out-of-school learning activities and to investigate how their participation in out-of-school learning activities as an observer within the scope of science courses creates a change in the situation of teachers. A case study was used in this study. Twenty-one science…

Students' opportunities to learn science are shaped by the intellectual work in which they engage in science classrooms. By considering the opportunity to learn as a more nuanced and complex concept than simply as exposure to the subject matter, we argue that the kind of tasks that teachers assign to students presents an important element to…

Laboratory courses are an important part of the undergraduate physics curriculum. During physics labs, students can engage in authentic, hands-on experimental practices, which can prepare them for graduate school, research laboratories, and jobs in industry. Because of the COVID-19 pandemic in Spring 2020, colleges and universities across the…

Scientific imagination plays an important role in learning science. The ways students interact with the learning activities in different classroom contexts can reflect their learning abilities. This research aimed to promote scientific imagination of lower secondary school students using a science learning activities package. The participants were…

Novice chemists often struggle with the highly visual nature of some chemistry topics. To make visually demanding concepts, such as isomerism and stereochemistry, more accessible to students, chemistry instructors have long recommended the use of molecular model kits as visual aids. However, studies pertaining to student model usage have shown…

The emergence of immersive VR technology in K-12 educational spaces has created a need for research examining the affordances and constraints of this technology for student learning. The current study uses a case-study methodology to illustrate K-12 secondary science teachers' perceived affordances and constraints of using immersive VR tools to…

This study aims to determine pre-service science teachers' metaconceptual activities about the design of processes to teach science concepts in their pre-active phase. A single-case design was used. The eight pre-service science teachers participated in this study. An activity journal and an instruction process evaluation developed by the…

This work aims to examine how science teachers ensured equity during the COVID-19 pandemic. The participants are six science teachers who were teaching in different middle schools within the Lisbon district. Their classes were heterogeneous, with students from different socio-economic backgrounds and ethnicities, and with diverse levels of…

Language, and thus scientific language, is essential for chemistry teaching and learning. To be able to successfully teach the scientific language of chemistry, the Chemish, (prospective) chemistry teachers need to possess pedagogical scientific language knowledge (PSLK).Thus, teacher preparation needs to focus explicitly on Chemish and its…

The application of effective teaching methods needs to be implemented to improve the quality of microbiology education which can empower important competencies in the current era. This study aims to analyze the application and trajectory of argumentation-based inquiry learning through the application of microbiology lectures. This research uses…
