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…

A virtual microscope resource was created when face-to-face labs were halted due to the COVID-19 pandemic in March 2020 to replicate the learning goals of an introductory petrology course on microscopy. This virtual microscope resource utilized images and videos of thin sections, as well as 3D rock models to allow students to complete labs online.…

Building a virtual laboratory for teaching and learning is a highly complex process, incorporating diverse areas such as interaction design, visualisation, and pedagogy. This article focuses on the production and implementation issues that were found in the comparison of two different virtual laboratory projects, and discuss which design…

Much of analytical chemistry involves the analysis of complex mixtures, where careful attention to sample preparation and method selectivity is required to avoid interferents and obtain accurate data. As this type of analysis is very different from simple colorimetric analysis that most students are exposed to in general chemistry, this laboratory…

We describe a project implemented in the honors section of an upper-level analytical chemistry undergraduate course, in which students designed an experiment to compare the performance of two analytical techniques to determine the amount of ascorbic acid in a commercial sample. This project designed for 18 students is composed of three stages. In…

Laboratory exercises focused on protein quantification are frequently conducted in traditional undergraduate biochemistry laboratory curriculum. The laboratory course described here is designed to provide students with experience in measurement of protein content in milk powder by moving reaction boundary titration (MRBT), a new rapid technique…

Digital learning environments such as virtual laboratories have been proposed to augment or even replace conventional forms of teaching in recent years. While there is some evidence on comparable learning outcomes between real and virtual labs, empirical evidence on the effectiveness of virtual labs as compared to conventional face-to-face…

Triggered situational interest in introductory courses can encourage student engagement, motivation, and value for the geosciences. In-person labs have traditionally played a unique role in triggering situational interest compared to lectures, but the COVID transition online disrupted these dynamics. We examine students' self-reported situational…

This paper examines the effectiveness of adding an online component to the general chemistry laboratory in which students view prelaboratory instructional materials through online videos prior to completing general chemistry laboratory activities. Using a quasi-experimental design, we compared the performance of 1089 general chemistry students who…

A comparative study on the performance and on the perception of two groups of students involved in a peer review activity on the writing of chemical laboratory reports is reported. The first group participated in a compulsory activity, while the second one participated on a voluntary basis. This study was aimed at determining whether the overall…

Despite the inherent potential of cooperative learning, there has been very little research into its effectiveness in middle school laboratory classes. This study focuses on an empirical comparison between cooperative learning and individual learning in the school science laboratory, evaluating the quality of learning and the students' attitudes.…

Polymer materials are indispensable in our daily lives. This makes polymer technology of critical importance in higher education. In particular, hands-on experiment-based practicals/laboratories with a focus on polymer science are of tremendous value in the undergraduate curriculum. Along these lines, hydrogels are highly cross-linked polymer…

Background: Students' well preparedness for laboratory sessions is of importance for a number of reasons including them being able to engage in and learn from the session and in acquiring the necessary laboratory skills needed for the scientific community and for possible further work in industry. To enhance the preparedness of the students an…

Inquiry-based laboratories were implemented into a General Chemistry Laboratory sequence, and the impact of these exercises on students' experimental design skills was assessed using a four-part assessment developed for this study. This assessment contained a multiple-choice section, a section asking students to explain their reasoning behind a…

The effectiveness of traditional face-to-face labs versus non-traditional online, remote, or distance labs is difficult to assess due to the lack of continuity in the literature between terminology, standard evaluation metrics, and the use of a wide variety non-traditional laboratory experience for online courses. This narrative review presents a…
