For educational institutions in science, technology, engineering and mathematics (STEM) areas, the provision of practical learning scenarios is, traditionally, a major concern. In the 21st century, the explosion of information and communication technology (ICTs), as well as the universalization of low-cost hardware, has allowed the proliferation…

The knowledge of the mechanical properties of polymers and other materials is essential for several tasks in the field of materials science, like component design and material development. The tensile test is one method of determining many of the material's most defining mechanical characteristics. However, the teaching of laboratory experiments…

In this study, it is aimed to develop practical teaching activities that can be used in optics teaching. For this purpose, a virtual laboratory environment was created in RayLab which is an application for design and simulation of optics on the iPad/iPhone. In this context, the dispersion of white light in the prism, the relationship between the…

Performing HPLC-based experiments in the undergraduate practical classroom is difficult because of the time required to perform an analysis. This limits the type of practical to one that undertakes a simple quantitative analysis. However, with the use of sophisticated simulators, such as the one employed in this exercise, more complex experiments…

Enzymes are nature's catalysts, mediating chemical processes in living systems. The study of enzyme function and mechanism includes defining the maximum catalytic rate and affinity for substrate/s (among other factors), referred to as enzyme kinetics. Enzyme kinetics is a staple of biochemistry curricula and other disciplines, from molecular and…

A study with K-9 Greek students was conducted in order to evaluate how the declarative knowledge acquisition was affected by incorporating Arduino experiments in secondary Chemistry Education. A Digital Application (DA) that blends the use of the Arduino sensors' experiments with digital educational material, including Virtual Labs (VLs), was…

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…

Aimed to adapt the experimental teaching to keeping up with the actual application of the experimental scene, an experimental teaching based on virtual-real combination for mobile communication was proposed in this article, which realized the collaborative mode of combining online virtual operations and real operations. The virtual experiments…

Inquiry-based learning can be an effective approach when students are provided with sufficient guidance. However, there is an ongoing debate among practitioners about the nature, type, and level of such guidance. This study investigated the effects on middle school students' (N = 116) conceptual knowledge and inquiry skills acquisition of…

The aim of this study is to reveal the effect of using virtual lab application in science teaching on students' academic achievement and students' views on virtual lab application. The study group of the research consists of 62 students studying in the 8th grade of a secondary school in Antalya in the 2019-2020 academic years. Mixed method design…

The glowing discharges of plasma obtained by introducing direct current high voltages between two electrodes in a chamber that contains a low pressure gas produces a spectacular effect that makes it attractive to be used as a laboratory experiment for students. Setting up this experiment is however costly and has crucial safety issues to be…

This research aimed to explore the effects of a virtual lab (VL) and a Microcomputer-based Lab (MBL) on students' performance in scientific modeling. A web-based virtual lab and a low-cost MBL were proposed to help first-year engineering students build scientific models. Empirical research was done in a slope motion experiment. The participants…

This article first put forward the educational application of immersive virtual laboratories for the problems of poor spatial thinking ability and weak hands-on operation ability. Second, aiming at the problems of a lack of excellent backbone teachers and insufficient educational information equipment, a Tibetan-Chinese bilingual immersion virtual…

Teaching through experiments has always been an indispensable teaching method in chemistry and other STEM disciplines. Letting more students have access to experiments at the frontier of scientific research is essential to stimulating students' interest in chemistry. With the advancement of computer technology, virtual simulation experiments…

Contribution: The evaluation of analog-to-digital conversion methods constitutes a key component of an Instrumentation course. This study introduces an affordable educational platform based on Arduino UNO board designed for teaching analog-to-digital conversion concepts, supported by virtual instruments (VIs). Background: ADCs are electronic…
