The Framework for K-12 Science Education set an ambitious goal of broadening participation in science learning for all students. Meeting this vision will involve supporting teachers in making meaningful connections with the cultural and linguistic resources their students bring to school; in essence, developing pedagogies that frame these…

This communication describes an updated experiment of peptide synthesis, involving determination of the loading capacity of a Fmoc-protected amino functionalized resin using UV-vis spectroscopy and a subsequent synthesis of a dipeptide in order to exemplify the experimental solid-phase synthesis procedure as an alternative technique in organic…

As the use of plastics expands, microplastic concentrations increase in aquatic environments and negatively impact water, soil, and animals inhabiting these areas. Microplastic research frequently incorporates citizen science to assist in data collection and environmental education. These projects provide opportunities for greater societal…

Motivational hands-on workshops for grade-school level future scientists are needed to inspire young and receptive minds. Described here is an educational event, titled "Inspiring Future Rocket Chemists", with hands-on laboratory exercises demonstrating the fundamentals of rocket flight and live chemistry demonstrations illustrating the…

The global Coronavirus disease 2019 (COVID-19) pandemic and associated restrictions on indoor gatherings posed considerable challenges to the delivery of courses that traditionally have relied on hands-on learning in their laboratory components. Here, our experiences converting a senior instrumental analysis course to remote online learning in the…

Heart muscle cells, or cardiomyocytes, exhibit intrinsic contractility in vitro. We found that commercially-available mammalian cardiomyocytes serve as an excellent model system for studying the cytoskeleton and cellular contractility, fundamental topics in undergraduate cell and molecular biology courses. Embryonic rat cardiomyocytes were plated…

Many studies have characterized students' difficulties in understanding and reasoning about scientific mechanisms. Some of those studies have drawn implications on teaching mechanisms and how to guide students while reasoning mechanistically. In this theoretical article, I claim that one component that has not garnered much attention in the…

Old physics textbooks give us a great opportunity to learn about the history of science and rediscover different methods to teach physics to our students. There are many disused and forgotten experiments in them, but these can still be very useful to affirm and understand physics. This is the case of an instrument used in the 19th century to…

The American Chemical Society advocates a shift from rule-based to risk-based safety education for chemistry graduates, emphasizing meaningful student engagement in the risk assessment process for laboratory work. To implement this paradigm shift, we introduced RAMP (Recognize Hazards, Assess Risk, Minimize Risk, and Prevent Emergencies)-based…

An integrated laboratory experience in X-ray photoelectron spectroscopy (XPS) is designed for undergraduate and graduate students in chemistry, materials science, and other related fields. Focusing on ubiquitous Si, Cu, and their common oxides, students are guided to characterize a series of standard materials by XPS to understand the fundamentals…

This paper reviews the current position of the history of education within the existing historiography of science and technology, and argues for the relocation of education from the periphery of the history of science and technology to its centre. It claims that it is essential to study science education in its entirety and complexity if we want…

This article presents a comprehensive exploration of ipsative and sociomaterial assessment methodologies, dissecting their theoretical frameworks, practical implementations, and the resultant effects on educational paradigms. The purpose of this article is to introduce a combined ipsative-sociomaterial assessment framework for science education at…

Integrating authentic research practices into introductory laboratory courses to prepare tomorrow's scientists has become increasingly prevalent over the past decade. However, an incomplete understanding of the nature of science (NOS) and authentic scientific inquiry (SI) precludes higher-level learning in undergraduate research experiences. In…

The importance of teaching the Luria-Delbrück experiment to biology students is increasingly recognized by educators, and improved pedagogical methods for teaching the classic experiment have been proposed and tested in the classroom. However, there are still obstacles that impede the proper teaching of the classic experiment. This note proposes…

In chemistry, a eutectic mixture refers to a mixture of two or more components at which the lowest possible freezing point is observed. This phenomenon is covered in a wide range of curricula such as physics, chemistry, chemical engineering, and pharmacy to various depths. Despite the significance of this phenomenon in pharmaceutical compounding…
