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…

In this paper we demonstrate that using mixed reality (MR) technology can innovate our chemical engineering laboratory curriculum at Prairie View A&M University, a Historically Black College/University (HBCU). Particularly, we describe the development of a MR proof of concept to carry out a traditional fluid mechanics lab -- pressure drop as a…

In the past decade, we have witnessed the emergence of a large number of different computer-based animations and simulations that have the goal to foster better learning of different physics topics. Past studies have shown many benefits of animations and simulations, but for their efficient usage it is very important that teachers are well…

The Van de Graaff (VDG) generator is ubiquitous in the physics laboratory, but the high-voltage discharges that emanate from it can cause user discomfort or damage to nearby electronics during experimentation. In this work, an augmented reality (AR) tool is developed to help students conduct the experiment safely. More specifically, it allows them…

The initial learning experience is a critical opportunity to support conceptual understanding of abstract STEM concepts. Although hands-on activities and physical three-dimensional models are beneficial, they are seldom utilized and are replaced increasingly by digital simulations and laboratory exercises presented on touchscreen tablet computers.…

As intriguing optical phenomena that occur in nature, mirages are widely known and often mentioned in physics classes when introducing the basics of optics. In the atmosphere, a mirage occurs under the condition of vertical variations in air density, which are usually caused by a temperature gradient. The light rays are continuously refracted and…

The current research strives for examining the power of utilizing computer-based simulations on students' academic performance and their perceptions of organic chemistry after using computer-based simulations during their learning of organic chemistry. The study adopted mixed-method research. A total of 72 students whose ages range from 16 to 18…

The use of simulations to better convey abstract scientific concepts or difficult-to-observe scientific occurrences through the manipulation of variables or virtual objects has the potential to improve student science learning. However, misconceptions or extraneous load may emerge if simulation support is insufficient. In this study, we used a…

The multiple benefits of virtual experiments applied to science education depend heavily on science teachers' intentions to use them. The inducing mechanism is a process that combines different conditions of multiple factors. From the perspective of overall configuration, this study used the fuzzy-set qualitative comparative analysis (fsQCA)…

Herein, we developed a mobile augmented reality (AR) application that can recognize chemical bonding by arranging markers on which atoms are augmented, in accordance with the specific characteristics of actual chemical bonding. From an educational affordance perspective, the development targets for AR application were selected to recognize…

The COVID-19 pandemic forced the adoption of online laboratories. The present article discusses the virtual laboratories used by students. The questions posed by students provided targeted teaching opportunities.

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology--digital body preservation--is presented for combining and matching scan geometry with radiographic imaging. The technique…

Understanding the physicochemical properties of organic compounds with potential biological uses is central in current research topics. Thus, students must pursue the integration of different fields of chemistry to obtain and understand the physicochemical parameters that characterize the mechanism of action of key organics compounds. This…

Augmented reality (AR) technology is increasingly present in chemistry teaching and learning processes. It is seen as an important pedagogical resource that allows enhancing the understanding of complex concepts at most educational levels. However, even though numerous benefits related to AR in education have been reported, no systematic review…

The Databank of Dynamics Trajectories (DDT, notthatddt.org) was established to assist students in visualizing the dynamical behaviors occurring during chemical reactions and conformational changes, with a focus on processes taught in introductory organic chemistry classes. Animations of reacting molecules created using "ab initio"…
