We present a detailed yet easy-to-follow discussion of the mathematical treatment of time-resolved spectroscopic data in a model-based approach. This is accompanied and complemented by an example of a colorful and pedagogically rich chemical reaction: the permanganate oxidation of sugars in basic aqueous media (often known as the chameleon…

In this laboratory experiment, students modify a series of surfaces and explore the effects of varying surface chemistry and texture on wettability by different probe liquids. Students begin by building a simple contact angle goniometer utilizing their mobile phone cameras. Next, they contrast the wettability of planar glass substrates…

The basic knowledge of chemical formula writing is fundamental for chemistry students, yet many still struggle to learn it. To provide a more interactive and engaging approach that facilitates and reinforces student understanding of chemical formulas and stoichiometry of chemical reactions, we have designed a chemical jigsaw puzzle. Only eight…

We review the literature, from 2006 to 2020, focused on the teaching and learning of chemical bonding. The studies included in our review (48 studies set in 19 different countries overall) involved secondary and postsecondary students as well as K-12 teachers and university faculty. We synthesize these studies' findings to provide implications for…

Water and an immiscible organic liquid are placed in a small plastic bottle. Ten small pieces of a notecard which is shaded on one side by crayon or pencil (graphite or colored) are cut out and placed inside the bottle. After capping and shaking, the notecard pieces float at the liquid-liquid interface with the shaded side facing the nonpolar…

This work further implements the "elements of inquiry" approach in a first-year undergraduate laboratory course, in a two-part inquiry sequence. In the first part of the sequence, students iteratively develop a "best-practice" TLC procedure. In the second part, students iteratively optimize a simple organic reaction using TLC,…

This paper describes the application of an accessible, benchtop mass spectrometer using an Atmospheric Solids Analysis Probe (ASAP) for easy sample introduction, coupled with Atmospheric Pressure Chemical Ionization (APCI) as a soft ionization technique, to the inquiry-based identification of the metal composition of alloys, including coins.…

Recent advances in laboratory automation and digitization require a teaching strategy for undergraduate students that is inclusive of skills in these areas so that students can be prepared to work within the modern laboratory. Future scientists will need training in coding, microcontrollers, on-demand manufacturing, and robotics. With this in…

In-service teachers of science work with unique content and pedagogical experiences. Understanding teacher agency in these circumstances will help researchers understand the actions that these teachers take, actions that are consequential for shaping teaching patterns and supporting the development of students' scientific practices. The purpose of…

Sustainability has a molecular basis that suggests a central role for chemistry in addressing today's challenges to Earth and societal systems, and this role requires educators to see chemical reactions and processes as integral parts of dynamic and interconnected systems. Despite this prospect, few accessible resources are available for students…

This book showcases a case study of the development of a generalist early childhood education (ECE) teacher into a confident and competent teacher of science in early childhood with support from a mentor. It argues that with guided mentoring, and later, timely support of a mentor as and when required, ECE teachers can deliver the curriculum, teach…

Understanding how and why science works is a major goal of science education. The aim of this article is to analyze the influence of a research experience in real science contexts, in the thinking and practice of preservice elementary teachers regarding inquiry and nature of science teaching. An in-depth case study which highlights the affordances…

"Introduction:" Teaching and learning are processes that significantly impact one's future. Active participation in school practises serves as a strong foundation for future educators. This paper aims to present the viewpoints and feedback of university students on chemistry lessons conducted in schools by fellow university students as…

Design activities are gaining interest as rich contexts for learning science, technology, engineering, and mathematics (STEM) subjects. STEM teachers may find this challenging however, as designing requires support that they are not used to providing. In a subject like chemistry, teachers would have to balance creativity and responsibility for the…

Science teachers and educators seek to promote equity and inclusion within their classrooms. Yet, many do not examine how their roles could reproduce oppression that continues to exclude certain groups of students. Centering on how oppression interacts with science teaching and learning, this naturalistic study observed Ms. William and her…
