In 2002, the Swedish National Food Agency and researchers from Stockholm University made an announcement regarding the presence of acrylamide in carbohydrate-rich foods that are exposed to high temperatures, with cereals, potatoes, and coffee possibly being the most significant sources of ingestion. Although limited data are available on assessing…

Introductory physics is a gateway course that is required for many science, technology, engineering, and mathematics (STEM) majors. In introductory physics courses, women and racially minoritized students often have lower grades and higher attrition than white men. Inclusive teaching is widely recommended to ensure that all students have the…

In the ever-evolving landscape of education, the integration of Information and Communication Technology (ICT) has emerged as a transformative force, reshaping the way we teach and learn across various disciplines. Among these disciplines, physics stands as a particularly fertile ground for harnessing the power of ICT to enhance teaching…

This study investigates the role of learning dimensions in planning and trialing teaching-learning sequences (TLSs) on surface phenomena in liquids for high school students. Particularly, it aims to identify how different modeling approaches--macroscopic and mesoscopic--impact students' learning in terms of different dimensions of learning such as…

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…

Pre-service science teachers develop their teaching practices within and across the university and school contexts of their teacher education programs. The practices and visions of teaching and learning emphasized in each context are often disjointed, a problem referred to as the "two-worlds pitfall." Responding to the call for teacher…

This systematic literature review seeks to investigate the pedagogical practices that can be used to encourage the inclusion of Indigenous knowledge in science classrooms. By adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline method, past studies on pedagogical practices in integrating Indigenous knowledge…

A chemistry laboratory experiment is described to introduce undergraduate college students to membrane separation technology. This experiment combines a simple nanowire membrane fabrication and visually indicated molecule separation. The membrane is produced via coprecipitation synthesis followed by a filtration assembly process, which can be…

This work gathers in one place what is pertinent about the connections between metric coefficients, basis- and unit vectors in a four-dimensional relativistic manifold. Some of this material can be found scattered elsewhere; its collection into one place reveals connections that either are not known or are obscure, for example that the metric…

This paper describes a data set of IR, MS, H-1 NMR, C-13 NMR, DEPT, and 2D NMR spectra designed for undergraduate teaching. The data files are provided as MestReNova documents containing all the available spectra for each of the 251 different compounds in the data set. The spectral data in these files can be processed, manipulated, copied, and…

Gamification of learning in chemistry education is a growing field. Chemistry themed escape room activities, incorporating course learning objectives into puzzle solution, have become a popular tool allowing for students to apply course knowledge in novel settings. Escape room activities, like their public counterparts, provide subtle guidance to…

Reactions between metal carbonates from d[superscript 5] to d[superscript 10] systems and glutamic acid are used to obtain molecular metal complexes and metal-organic frameworks (MOFs). When the ligand is an amino acid, these MOFs belong to the BioMOF class (metal-organic frameworks for biological and medical applications). The metal carbonates of…

The mechanistic approach to teaching introductory-level organic chemistry--Organic One and Two (Organic I and II) in the United States--continues to predominate since its introduction through Morrison and Boyd's legendary textbook. In this approach, reactions are taught alongside their electron-pushing mechanisms (EPMs), thereby providing students…

Inquiry-based teaching is the most widespread approach in science education worldwide. However, in Peru, this model became better known since the latest curriculum reform in 2016, which proposed implementing that teaching approach at all levels of schooling. Since then, no literature review has been conducted on the status quo of implementing…

For many years, hegemonic approaches to teaching the nature of science (NOS) have focused mainly on understanding some epistemic (i.e., rational, or cognitive) aspects involved in the construction of science. So, aspects of a non-epistemic (i.e., non-rational, contextual, or extra-scientific) nature have been practically neglected in these…
