A problem-based learning activity focusing on the human impact on the environment and the importance of sustainable development is presented. The activity revolves around a mysterious island where the civilization is on the blink of extinction, prompting students to investigate how human behavior, ecosystems, resources, and natural balance…

Anaerobic respiration reactions are of fundamental importance to global biogeochemical cycling of elements. Yet, the idea that cellular respiration can occur not only in the absence of oxygen but also involve the oxidation of inorganic substrates (e.g., AsO[subscript 3 superscript 3-], Fe[superscript 2+], H[subscript 2], H[subscript 2]S,…

There has been sustained research interest in the role of early career researchers in advancing the field and the challenges that they face. However, efforts to document lived experiences of researchers working in a specific research area within science education have been scarce. This paper considers the meaning of innovation in the context of…

Across decades, science educators have invested in curricula that presume scientific unity. The phrases "habits of mind, scientific method, processes of science, inquiry skills, nature of science, practices of science" reflect this obsession. However, historians look with skepticism at universal notions of science and endorse…

A new approach, termed the "scale factor method," is presented for solving a variety of stoichiometry problems. Students taught to solve mass-mass stoichiometry problems using this method found it more intuitive and had a higher rate of success than students using the traditional dimension analysis approach. The scale factor approach…

By arguing for "putting science education in its place," this essay cautions against overstating the role of science education with respect to global crises with technical components, like climate change. At the same time, it challenges the assumption that science education has no role in addressing equally urgent and widespread problems…

Herein, we present a program implemented in Python that utilizes a simple complete-search algorithm to determine the geometry of a lanthanide-substrate (LS) complex. The program serves as a practical project in a programming course for chemistry students, specifically aimed at illustrating fundamental concepts such as decision-making, repetition,…

The article presents a 5E environmental science lesson to help students understand the major environmental factors that lead to acid rain. Students are supported to ask scientific questions to solve the mystery of how acid rain might impact historical buildings. This lesson can be used in a variety of settings both in person and online modalities.…

The COVID-19 pandemic is a historic global event that has extended to all parts of society and shaken the core of what we know and how we live. During this pandemic, the work of STEM professionals has taken center stage. Through our close observations of how the events of the pandemic have been unfolding across the globe, we propose an…

For most students, completing practice problems is an essential prerequisite for success in organic chemistry courses. Practice work, however, is sometimes perceived to be easier than or even not related to the types of chemistry that students see in assessments and "real-world" science. This negative view may contribute to a reduced…

A science, technology, society, and environmental (STSE) impact assignment framework was developed that bridges the gap between analytical chemistry education and broader societal and environmental contexts. Over the course of [approximately]8 weeks, students were provided with the opportunity to engage in a self-directed learning opportunity to…

This paper describes the implementation of problem-based learning in chemical education with regard to the impact that protolytic reactions have on equilibria. The problem-based task presented here is focused on extremely weak acids and calcuation of the pH value of their aqueous solutions. The task is based on comparisons of K[subscript a] ranges…

Amy Strachan and Jemima Davey's new book, "Saving the Planet One Science Lesson at a Time" (Strachan and Davey, 2022) uses the UN Sustainable Development Goals (the blueprint to achieve a better and more sustainable future for all; United Nations, 2015) as a framework to show that science knowledge and skills can support the achievement…

This article describes how preservice elementary teachers learn about the nature of science and develop scientific literacy through a collaborative project that prepares them to design meaningful learning experiences for students. The Life's Replica Project was an effort between a college professor and an elementary school teacher to facilitate…

In this article, we present a hierarchical model for teaching scientific thinking to gifted students. This article follows up on an article published 40 years ago in this journal. The problem now, as 40 years ago, is that gifted students often are taught science courses at a more intensive level, but without their truly learning how to think…
