The ability to express scientific concepts in mathematical terms and integrate scientific and mathematical reasoning about a phenomenon is a foundational cognitive process involved in scientific thinking. This process called "blended math-science sensemaking" (MSS) is a desired skill for all science, technology, engineering, and math…

Theoretical and practical foundations of basic electrochemical concepts of heterogeneous charge transfer reactions that underline electrochemical processes are presented for their detailed study by undergraduate and postgraduate students. Several simple methods for calculating key variables, such as the half-wave potential, limiting current, and…

The development and application of a simulator designed with Excel spreadsheets to teach procedural skills in atomic absorption spectrometry and atomic emission spectrometry are proposed. For the development of the simulator, different analytical procedures were followed including analysis of pharmaceutical, forensic, and environmental samples.…

Proper sampling techniques are of the utmost importance in obtaining accurate and precise results in chemical analysis. A Python language computer simulation providing fast feedback on sampling concepts and statistics was delivered to students through Google Colab. Students used the simulation to aid in their exploration of sampling and sampling…

Cyclic voltammetry (CV) is the most popular electrochemical technique for the study of electrode processes. One of the reasons for its popularity is its adjustable timescale which can vary several orders of magnitude simply by varying the rate at which the potential is scanned. Changing the scan rate affects CV features including the current,…

An educational escape activity was developed, embedding elements of both augmented and immersive virtual reality technologies, in an active learning environment. The mental visualization of abstract concepts can be difficult for students, inhibiting their ability to reason cogently regarding important topics of stereochemistry. Consequently, an…

This paper presents an analysis of cognitive skill levels expressed in high school students' performance using laboratory simulations. We address lower-order cognitive skills (LOCS) and higher-order cognitive skills (HOCS) situations in a virtual simulation activity, in order to identify and underly further discussions about students' reasoning…

There is little doubt that motivation influences the extent to which individuals engage with online learning experiences. With the increasing role of digital technologies within chemistry higher education, this study illustrates how an augmented reality (AR)-supported educational escape activity (EEA), based on topics of inorganic stereochemistry,…

Research in the past decades repeatedly revealed university students' struggles to properly understand physical chemistry concepts. In contrast to school, tertiary teaching relies heavily on the symbolic level, mainly applying abstract representations such as equations and diagrams. To follow the lessons and generate conceptual understanding,…

Implementation of the flipped classroom approach into STEM courses has been popularized in the last decade and has generally been reported to improve student performance outcomes. In a flipped classroom setting, students typically first encounter course content in the online format and subsequently engage in some form of active learning during the…

Inquiry activities with component visualization tools are increasingly prevalent in K-12 STEM classrooms; however, evidence of their efficacy has primarily been collected from controlled laboratory studies that lack ecological validity or from small-scale classroom interventions that assess learning outcomes proximal to the intervention. Here, the…

For six semesters, activities have been incorporated into first year general chemistry courses in an effort to build student conceptual chemistry knowledge. The activities follow a learning cycle pedagogy (similar to Process Oriented Guided Inquiry Learning or POGIL activities) and consist of guiding questions involving animations, models,…

In this article, we focus on a set of remote activities regarding simulated juries, judges' evaluations, communication of verdicts, and a post-discussion conversation. These activities aimed to promote learning of the preservice teachers about the differences between remote and in-person teaching in a chemistry teaching methods course. The set of…

Computational approaches toward simulating chemical systems and evaluating experimental data has gathered great momentum in recent years. The onset of more powerful computers and advanced software has been instrumental to this end. This manuscript presents a hands-on activity which trains students in basic coding skills within the Matlab…
