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…

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…

Learning in the computer laboratory is an important component when students learn computer programming. In this article, we analyse empirical data on novice students working in pairs in the laboratory. Using an approach inspired by phenomenography and variation theory, we specifically focus on how students' learning of theory and their learning of…

University research labs focusing on education, psychology, and cognitive development have been collaborating with museums more and more over the past decade. Nevertheless, cognitive science labs that primarily engage in basic as opposed to applied research may find it difficult to entice museums to collaborate, and existing collaborations may…

Undergraduate mathematics tutoring centres are prevalent in many countries; however, there is limited research-based evidence on effective organizational structures for these centres. In this study, we consider two research questions. First, how can the quantitative and qualitative data from 10 mathematics tutoring centres be organized for…

Important works in the Dewey corpus -- particularly those discussing the theory and practice of art and aesthetic education, prepared from 1896 through 1900 while Dewey was working out the plan for the University's Laboratory School--remain virtually unstudied. When interpreting or building upon Dewey's theory of art and art education, scholars…

Choreographed encounters with death in Copenhagen Zoo, such as school and public dissections, emphasize the importance of touch and are underpinned by the moral imperative to understand the nature of life and death. Such encounters are framed by zoo educators as contributing to a deeper environmental awareness. Taking the role of dead animals in…

This essay presents a reflective account of the origin story of a linguistics justice initiative within the writing center. It concludes by posing questions aimed at promoting dialogue among writing center practitioners as they consider similar initiatives within their own contexts.

As the 21st century progresses, we are increasingly reminded of the importance of and need for green chemistry, which also leads to the corresponding need for green chemistry education. The UC Berkeley Department of Chemistry developed a green chemistry laboratory curriculum-the "General Chemistry Green Curriculum" ("GC[superscript…

Here we demonstrate how data from the clinical pulmonary function lab can help students learn about the principle of airway-parenchymal interdependence. We examined the relationship between airway conductance (Gaw) and lung volume (thoracic gas volume, TGV) in 48 patients: 17 healthy; 20 with emphysema, expected to have reduced airway-parenchymal…
