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…

It is difficult for students to learn the concepts of chemical laboratory safety education from actual experiences because the traditional teaching model prohibits students from performing dangerous operations. Therefore, this study develops a novel mixed reality-based chemistry experiment learning system (MRCELS) to allow learners to conduct…

Despite the growing importance of nanomaterials in numerous industries, most undergraduate chemistry students are unlikely to encounter characterization techniques common in the field during their education. Scanning electron microscopy (SEM) is a common technique for materials characterization widely used in careers chemistry students are likely…

This paper reports an immersive virtual reality lab (iVRLab) training environment that offers college students an immersive and embodied experience in engineering lab work. The iVRLab provides a simple and safe environment for students to learn the complex lab operations to process and prepare silicon wafers. It features highly embodied…

Development and evaluation of a teaching-learning activity in 4th year Forensic Physics course of Degree in Criminology was based on different combinations of a virtual laboratory and a research laboratory as teaching spaces. Students explored in detail the components and functioning of an electron microscope using both an online suite of…

Access to laboratory facilities and associated instrumentation represents a major barrier to learning in physical science education, due to constraints introduced by limited time and financial resources, cost of acquisition, and health and safety requirements. Virtualized laboratories offer some mitigation of these problems but may also introduce…

Virtual reality (VR) provides significant opportunities for students to experience immersive education. In VR, students can travel to the international space station, or go through a science experiment at home. However, the current tactile feedback provided by these systems do not feel real. Controllers do not provide the same tactile feedback…

In virtual laboratories, various cognitive aids are used to improve students' performance and assist them while completing experimental tasks. However, excessive use of cognitive aids in virtual laboratories can lead to a cognitive load on students which affects their performance. In this paper, we proposed the concept of adaptive aids virtual…

Background: An increasing number of educational institutions are incorporating virtual reality (VR) applications in the instruction methodology for their laboratory science courses. However, there is debate about the use of the physical vs. the virtual lab as according to research the former offers a positive research-training environment, whereas…

In this paper we explain how to build a very sensitive force table using 3D-printed parts. The key component of this apparatus is a simple sensitive pulley that, together with the other components, can be printed in one day (one hour per pulley, 17 hours for a complete three-pulleys table) at the cost of 160 g of plastic filament. This force table…

A virtual catalytic reactor laboratory (VCRL) experiment, which can be used in most browsers, is described. Students select feed conditions and use the VCRL to take data for a gas-phase catalytic reaction and fit kinetic parameters to a Langmuir-Hinshelwood rate expression. The VCRL contains instructions, equipment descriptions, an animated…

Because of the recent pandemic, new teaching methods have been trialed, even in traditional disciplines such as histopathology that typically involve extensive hands-on laboratory work. In this study, we investigated the effects of three different learning modalities in histopathology teaching: optical microscopy, in-class virtual microscopy (VM),…

Many modern anatomy curricula teach histology using virtual microscopes, where students inspect tissue slices in a computer program (e.g. a web browser). However, the educational data mining (EDM) potential of these virtual microscopes remains under-utilized. In this paper, we use EDM techniques to investigate three research questions on a virtual…

This study presents an evaluation of virtual laboratory simulation for educational use in the "AP Degree Programme in Chemical and Biotechnical Science at University College Copenhagen" in Denmark. The purpose was to test if, and how, virtual laboratory simulation could be applied to a practically oriented education such as the education…

This study presents the integration of three different teaching scenarios, during biology laboratory lessons, with the overall aim of exploring the potential predominant effectiveness of teaching and improvement of students' learning, by the use of the three-dimensional virtual reality educational tool Onlabs, versus more traditional didactic…
