Mechanistic explanations, aiming to disclose details of entities and their activities, employ the act of unpacking which, inherently and paradoxically, produces explanatory gaps--pieces of undisclosed, undetailed mechanistic information. These gaps, termed explanatory black boxes, are often perceived as counterproductive to the teaching of…

The implementation of science reform must be viewed as a systems-level problem and not just focus on resources for teachers and students. High-capacity instructional leadership is essential for supporting classroom science instruction. Recent reform efforts include a shift from learning about science facts to figuring out scientific phenomena in…

Language is a fundamental tool for learning science. This study highlights the importance of teacher knowledge in utilising language as a tool for knowledge generation in the classrooms. This case study examines elementary teachers' development of declarative, procedural, and epistemic knowledge related to using language, particularly focusing on…

Virtual Reality is an emerging technology that has not been widely adapted to teach science concepts to students with significant cognitive disabilities (SCD) in part due to teachers' lack of understanding and technical competence. This narrative case study aimed to recount the experiences of teachers of students with SCD as they engage in…

This study investigated the impact of Open Educational Resources (OER) on the professional development of Bhutanese Physics teachers. Collaborating with partner institutions in Tanzania, Nigeria and India, Samtse College of Education developed and implemented three physics modules: Force and Motion; Work, Power and Energy; and Electromagnetism.…

A distinctive aspect of science teaching is the use of various strategies to stimulate students' discovery-oriented curiosity. However, many instructional knowledge models overlook teaching methodology as a predictor of quality science instruction, as noted in the Technological Pedagogical Content Knowledge model. This study developed and tested a…

National standards that centre on the underpinning epistemic practices of the discipline has emphasised the need for teachers to focus much more on knowledge generation approaches to learning. Adopting a complexity perspective, we attempt to understand how teachers shift over time by examining their epistemic orientation to knowledge generation…

This article examines the impact of a professional development program aimed at encouraging high school teachers to include more modern physics in their enacted classroom curricula through improved content and pedagogical knowledge. The program was implemented with 17 high school physics teachers (three were the focal point of this study) in…

Promoting socio-scientific issue (SSI)-based instruction in Indonesian science classrooms requires competent science teachers. To understand teachers' perceptions about the implementation of SSI-based instruction, a case study involving four biology teachers engaged in a teacher professional development program was conducted. The program consisted…

While research has investigated elementary teachers' understanding of science content, such research is often limited to topics typically not addressed in elementary school curricula. Yet, research has illustrated that many elementary teachers struggle to accurately articulate and teach science concepts and professional development (PD) is needed.…

Teachers are eager for professional development on teaching evolution, especially if it includes direct ties to relevant curricula and detailed lesson plans. Howard Hughes Medical Institute's BioInteractive Online Professional Learning: Evolution course was developed to provide educators with free, in-depth, multimedia resources that highlight…

Using Bruno Latour's framework of a "collective of humans and nonhumans", this paper presents an analysis of chemistry instruction in a high school curriculum and professional development setting to present the chemistry education community with a new way to think about reality and knowledge construction and, at the same time, to…

Research has highlighted the significant decline in teachers' implementation of newly acquired teaching practices following professional development (PD), primarily attributed to the absence of follow-up support. Even science teachers who have participated in intensive PD programs often encounter challenges in integrating new teaching practices…

The purpose of this study was to identify the Argumentation-based Inquiry (ABI) process from the perspective of teachers implementing the approach and determine the impacts of the process on both teachers and students. The researchers conducted the study via qualitative research methods. To this end, three science teachers teaching in three…

Playground Physics is a supplemental middle school science program designed to support embodied learning by enabling students to connect physics concepts to their own playful activities. The purpose of this study was to examine a model for scaling up the Playground Physics program and to determine the program's impact on middle school students'…
