Ion transport, involving the diffusion and migration of ions within the electrolyte, stands as a fundamental concept in electrochemistry and serves as the driving force for electrochemical reactions. Electric double layers are critical in the fields of electrochemical energy storage and chemical conversion, constituting a central focus of…

Chemical engineers must learn to connect concepts across vastly different scales, spanning from molecular structures to industrial processes. Here, we explore the use of a virtual-reality simulation with a companion video of an experiment to help undergraduate students connect nanoscale fundamentals to macroscale engineering observations.

The double-indicator method is often used in the analysis of Na[subscript 2]CO[subscript 3], NaHCO[subscript 3], and NaOH mixtures (carbonate mixtures). In this method, the determination of the volumes at the first and second equivalence points plays a crucial role in analyzing the composition and content of the carbonate mixtures. Here, LabVIEW…

It is crucial nowadays to predict in a fast and simple manner physical-chemical behaviors like, the size-dependent optical properties of gold nanospheres (Au NSs). The idea behind this experiment is trying to replace (as much as possible) robust and expensive microscopy techniques with UV-vis spectrophotometry and friendly simulations. Students…

Challenge: While hands-on laboratory experiences are an important component of biomedical engineering curricula, many of the topics which would often benefit most from these experiences are often too time-, space-, and resource-intensive to incorporate into laboratory classes. One such topic is electrophysiology, where phenomena are hard to…

HOBIT, which stands for "Hybrid Optical Bench for Innovative Teaching and learning" is an educational platform that leverages the combination of numerical simulation and physical manipulation to facilitate learning of complex phenomena and motivate users about wave optics in practical work. HOBIT operates in real time and is…

Background: The adoption of virtual laboratories (VLs) has experienced a significant surge, catalysed by the global changes in the educational landscape, notably influenced by the COVID-19 pandemic. Originally supplementary to traditional in-person laboratory experiments, VLs swiftly transitioned into a primary source of hands-on laboratory…

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…

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…

Online video experiments are a promising educational technology tool for science laboratory classes. In order to find optimal instructional designs and scenarios for using online video experiments, we need to study learners' experiences. This work describes implementation of an online interactive video experiment at the undergraduate introductory…

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)…

Conducting experiments fosters conceptual understanding in science education. In various studies, combinations of real (hands-on) and virtual (computer-simulated) experiments have been shown to be especially helpful for gaining conceptual understanding. The present systematic review, based on 42 experimental studies, focuses on the following: (1)…

A qualitative sugar identification laboratory was adapted from a hands-on experiment to a virtual "choose your own adventure" experience where students select virtual experiments to conduct on samples of known and unknown carbohydrates. Students select positive and negative controls for each qualitative test and compare results from the…

Computer-simulated experiments have been gaining popularity over hands-on experiments in science education, given the availability of technology and the trend of distance learning. Past studies have focused primarily on comparing the learning outcomes and user experiences of the two experiment modes. In this study, we used an eye tracker to…

For nearly two decades, augmented reality (AR) has found diverse applications in education, particularly in science education, where its efficacy has been supported by relevant theories and many empirical studies. However, previous studies have revealed the following research deficit: While AR technology appears to influence learning-related…
