The undergraduates in the major of Environmental Science and Environmental Engineering frequently ignored the importance of identifying pollution sources for water environment monitoring and knew little about the techniques of identifying pollution sources. Thus, a laboratory experiment which focused on pollution sources identification in a water…

When laboratory accidents in schools, especially in recent years, are examined, it is remarkable that many of these events resulted from the incorrect implementation of laboratory safety. The most significant role in the administration of laboratory safety belongs to science teachers. During this process, the necessity of laboratory safety…

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…

Accuracy and precision are measures of experimental error and are fundamental to most chemical analysis laboratory classes. Assessment of accuracy and precision is often based on the comprehension of the results generated by students rather than on the quality of the data generated. This activity focused on developing a chemical analysis…

Contribution: An innovative teaching experience carried out at the University of Trento using team-based learning (TBL) in a large computer networks class. The impact of TBL on the students' learning and satisfaction was investigated. Background: Active learning pedagogies, including TBL, play an important role in enhancing higher-order cognitive…

This paper describes an innovative, new, laboratory experiment conceived as a Senior Capstone Project by the student authors to provide experience with heat pipes for students in our junior-year Process Laboratory course at the University of Utah. Heat pipes can transport energy over long distances with minimal temperature gradients and no moving…

Gross anatomy courses utilize cadaver dissection to teach identification, topography, and spatial relationships of organs. The deconstructive nature of dissection, however, focuses students' attention on the "big picture", followed by a discovery of details. This approach may be useful for many, however some students may prefer to…

A comprehensive educational framework is provided by the Conceive-Design-Implement-Operate (CDIO) which is particularly relevant to engineering and applied sciences. This paper investigates the application of the CDIO approach in the field of chemistry pedagogy in Vietnam focusing on its adaptability to the current educational demands and its…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] Research on nontraditional laboratory (lab) activities in physics shows that students often expect to verify predetermined results, as takes place in traditional lab activities. This understanding of what is taking place, or…

This paper introduces hands-on curricular modules integrated with research in atmospheric ice nucleation, which is an important phenomenon potentially influencing global climate change. The primary goal of this work is to promote meaningful laboratory exercises to enhance the competence of students in the fields of science, technology,…

Triboluminescence is a fascinating phenomenon that can engage students' interest in chemistry. However, safe, cost-effective, and accessible laboratory experiments featuring highly triboluminescent substances are limited. To bridge this gap, we present a simple, rapid, semimicro test tube preparation of the visually engaging manganese complex…

The COVID pandemic forced teachers to be imaginative, especially with purely practical subjects such as laboratory chemistry. In the Universidad Nacional Autónoma de México, the first-semester chemistry laboratory of the Biology course was taught with a chemistry set to be used at home. The use of the kit was evaluated from the perspective of…

Despite decades of reform efforts, STEM education continues to face calls for improvement, especially regarding the teaching laboratory. Establishing an empirical understanding of the types of hands-on, psychomotor skills that students need to learn to succeed in downstream careers could help ensure laboratory courses are promoting authentic…
