A variety of strategies have been introduced to tackle the issue of laboratory safety in academic settings. These strategies include innovative educational tools as students transition from the classroom into the laboratory, the introduction of policies designed to protect the researchers in the laboratory environment, and the creation of teams of…

To optimize learning experience and improve learning performance, current virtual experimental systems usually assist students with stepwise guidance before operations and feedback after them. However, stepwise and excessive guidance can lead to student overreliance, while late feedback cannot avoid potential errors during experimental learning.…

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…

Natural sciences can be difficult to grasp because physical and chemical phenomena can take place across time and length scales that are beyond the reach of human perception. This problem is particularly true for students attempting to learn about microfluidics, a discipline that involves intricate engineering methods and fluid phenomena that are…

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…

The calcium hydroxide solubility product constant ("K"[subscript sp]) lab is a familiar lab experiment outlined in the "Advanced Chemistry with Vernier" handbook. In an on-campus laboratory setting, students are afforded the opportunity to examine techniques, such as titration of a saturated base solution (Ca­(OH)[subscript 2])…

Capillary electrophoresis is a powerful separation tool with a wide range of analytes for diverse applications and is compatible with various detection methods. While some more established separation techniques like gas or liquid chromatography are utilized heavily in analytical chemistry laboratory courses, newer commercial capillary…

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…

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…

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…

Recent global events and educational trends have led schools to heavily rely on digital media to educate their students. Science classes, in particular, stand to lose substantial learning opportunities without the ability to provide physical laboratory experiences. Virtual reality (VR) technology has the potential to resolve this issue, but little…

Given the importance of self-healing polymers for chemistry education, herein, we introduce our latest research results in self-healing materials based on thioctic acid into undergraduate chemistry laboratory. In this experiment, a natural small molecule, thioctic acid (TA), and a few other commercially-available reagents have been used to make a…

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…

This study was conducted to determine the effectiveness of virtual laboratory based on semi second life (s-SL) on higher order thinking skills of general senior secondary school in chemistry learning process. The research design was adopted posttest only design approach to a quasi-experimental. This study was conducted in the one of public general…

Guided by the 5E framework (Engage, Explore, Explain, Elaborate, Evaluate), a buffer solution courseware was designed using "Articulate Rise," a content authoring tool. It was deployed in a freshman general chemistry course in the April semesters of 2022 and 2023. The courseware was a supplementary resource to support instructor-created…
