Modern astronomy as a field of inquiry may be shaped by what we consider the "scientific" ways of knowing. However, the history of astronomy as a human endeavour dates back millennia before the "modern" notions of "science". This long history means that astronomy is, at its core, built on a rich cultural diversity and…

Within physics education research (PER), resource theory has proven to be a useful framework for investigating knowledge and learning and informing instructional design. To analyze learning over longer timescales and across cases, PER scholars must first identify and describe the resources activated within and across physics contexts and domains.…

When deriving the equation describing the transverse motion of a one-dimensional vibrating elastic string, introductory physics textbooks often assume constant tension and/or small amplitude vibrations. However, these simplifying assumptions are not only unnecessary, but they overlook the elastic nature of the tension and yield an inconsistent…

Chemistry is a systems science that deals with complex-dynamic systems and systems thinking is an essential aspect of chemical practices. Thus, a systems thinking approach is needed in chemistry education for meaningful learning of the subject matter. Despite this necessity, systems thinking has not received sufficient attention in chemistry…

Reform documents advocate for innovative pedagogical strategies to enhance student learning. A key innovation is the integration of science and engineering practices through engineering design (ED)-based physics laboratory tasks, where students tackle engineering design problems by applying physics principles. While this approach has its benefits,…

The release of NGSS in 2013 brought forth uncertainty among K-12 educators on how to translate these standards into practical science lessons (Harris et al., 2017). One important instructional change that teachers still need assistance with is supporting sensemaking. To guide students in the process of sensemaking, teachers must ask questions that…

Information literacy skills are an important part of research skills for undergraduate science students. This case study presents a novel approach to developing these types of research skills. By deconstructing the research process into separate steps, explicitly defining, and practicing the skills involved, students can progressively develop…

Electromagnetic induction, represented by either Faraday's law or the Lorentz force law, produces many paradoxes requiring careful examination and application of these laws. The paradoxical example of induction, presented herein, arose in a class and is resolved within the framework of special relativity.

Mentoring to many is the informal highly unstructured teaching, advising, and nurturing which we receive from various individuals during our school years and professional lives and then give back to our students and more junior colleagues. However, with the advances in science and technology, the increasing competitiveness in the workplace, fast…

Background/purpose: The current trend of training Chemistry teachers focuses on innovating pedagogical methods and developing students' holistic competencies, particularly their chemistry experimentation competencies (CEC). The CDIO (Conceive - Design - Implement - Operate) framework effectively combines theoretical knowledge with practice and…

In this laboratory experiment, students evaluated three silver(I) complexes as potential additives for dental adhesives based on bacterial growth inhibition, heat stability, water insolubility, and cost-effectiveness. Each student prepared and analyzed a cyanoxime ligand and its corresponding silver(I) complex. Students characterized the…

Researchers have typically identified and characterized teachers' knowledge bases (e.g., pedagogical content knowledge and subject matter knowledge) in an effort to improve enacted instructional strategies. As shown by the Refined Consensus Model (RCM), understanding teacher learning, beliefs, and practices is predicated on the interconnections of…

Universal Design for Learning (UDL) provides a framework, based in brain research, to design instruction around the needs of all learners. By considering the UDL principles as educators design science instruction, they can proactively address how to engage students, how to make content accessible, and how to provide options for students to…

There is a pressing need to develop processes to facilitate the organization of education responses in time-pressured emergency situations. As part of a joint Learning Passport (LP) partnership project with UNICEF, researchers along with curriculum and subject specialists at the University of Cambridge, UK, developed a curriculum framework that…

Engaging preservice teachers in the analysis of videos of teaching has become a widely-used and highly-regarded approach within teacher preparation. This approach has become even more pronounced in the wake of COVID-19. Despite the myriad ways that video can support teacher preparation, uncertainties remain regarding how to design and facilitate…
