The complete structural analysis and resynthesis of an unknown compound, selected from a library of dipeptides, provided a framework for a course that built from expository experiments toward a guided-inquiry approach. We used this semester-long lab as a replacement for conventional second semester organic chemistry laboratory and successfully…

General education science courses at a Canadian postsecondary institution implemented "Beyond Labz" virtual science labs. Faculty members teaching vocational science-related courses tested this resource. This qualitative study explores faculty member and learner perceptions of the efficacy of these virtual labs in terms of ease of use,…

Contribution: This article proposes a low-cost and mobile device-based learning support system for the stepper motor, which provides Web-based remote laboratory. This system allows young engineers to learn about rotational principles, control methods, and programming in stepper motors. Background: Familiarity with electrical machinery, such as…

Students were tasked with the creation of videos of ordinary reactions to promote significant learning of complex concepts underlying chemical transformations. Interactive infographics were used to deliver instructions. Afterward, students planned the experimental setup for the reaction execution and video recording using their mobile phones. The…

Hydrogen is a sustainable and climate-friendly storage for renewable energies and can directly be generated from sunlight, e.g., by photocatalytic water splitting. This article presents the photocatalytic hydrogen evolution using LED irradiation of an aqueous ZnS particle dispersion with Na[subscript 2]S and Na[subscript 2]SO[subscript 3] as…

The development of the skills to read and understand scientific literature is crucial to the future success of students. A literature review project was introduced into an organic chemistry laboratory course, in which undergraduate students were asked to acquire the skills of scientific literature searching, reading, and summarizing. The course…

A national survey of chemists (n = 174) explored the self-reported format and focus of postsecondary inorganic chemistry instructional laboratory curricula. Multiple instructional laboratory course formats were observed, including stand-alone inorganic chemistry instructional laboratory courses, inorganic chemistry laboratory instruction as a…

Laboratory classes are a central element of all biochemistry and molecular biology programs. These play a role in developing students' hands-on and technical skills and also offer much more. The design of laboratory classes depends on many factors including the programs the students are enrolled in, the level they are at, employment destinations,…

Due to coronavirus disease 2019 (COVID-19), universities were restricted from gathering students for in-person instruction, especially teaching hands-on techniques in microbiology laboratory courses. This report describes how a Hispanic-serving institution (HSI) transitioned to remote learning for microbiology laboratories through a model, PRUTE,…

Descriptive statistics involves summarizing and organizing data so that they can be easily understood. Even though these are basic and simple concepts, many applied science students have misconceptions about their use in applied experiments in the laboratory. Students usually receive limited or no training in how to understand the meaning of the…

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…

Interdisciplinary experiments within chemistry are very important for the improvements in the overall quality of the education received by students. In this work, we describe an interdisciplinary experiment that was successfully completed by undergraduate students. This training integrates multiple disciplines including natural product medicinal…

Diversity in teams has been shown to enhance creativity and innovation, particularly in teams where all members felt a sense of belonging. Creating an inclusive environment in a lab setting that provides a sense of belonging to all is challenging. This is particularly true in a field like Biomedical Engineering/Bioengineering where diversity is…

Affect and emotions matter to science learning. They also matter because they are integral to science identity formation and sense of belonging. This study aims to foreground the epistemic and affective character of laboratory work in higher science education by conceptualizing it as epistemic practice, in which students activate their body and…

Chemometric techniques such as partial least-squares (PLS) regression have been applied with huge success to a wide array of chemical problems including multicomponent analysis of analytes in complex mixtures. Despite this, there are few examples of laboratory pedagogical exercises that involve students in the acquisition of chemical data from…
