The demand for sustainable synthetic methods in modern industry has been increasing rapidly due to the requirements of environmental protection and energy conservation, which has brought organic electrochemical synthesis to the forefront nowadays. Here, a two-part laboratory experiment has been designed to train undergraduates in comprehending and…

This paper examines the findings obtained in a chemistry laboratory course provided through online hands-on activities during the pandemic. Case study design, one of the qualitative research methods, was used. The data collection period was 8 weeks. The study was carried out with 16 third-year pre-service science teachers within the scope of a…

The practical demonstration of electrolysis is a foundational example of electrochemistry that is often introduced to students during secondary education. However, when students subsequently encounter solid polymer electrolytes, such as proton exchange membranes (PEM), they may experience confusion due to the added complexities. In this work, we…

The teaching of laboratory skills to undergraduate students is central to all experimental sciences. In this setting, students must understand the experimental procedures as well as the fundamental principle(s) being demonstrated, all while learning within a limited time. Other limiting factors include access to equipment and reagents, resulting…

Purpose: The aim of this paper is to explore how the involvement of workplace teams in experimenting with changes in their work practices through short, time-boxed, experiments (STBEs) can support organizational learning. It is explored how staffs' experiences with experimental practices give rise to shared knowledge and how this is supported by…

Online laboratories have been widely used in education, research, and industrial applications. For online laboratories, various architectures have been constructed to provide good user experience and powerful capabilities for online experimentation, in which the controller is a crucial part to connect the server with a controlled test rig.…

Numerous academic studies in the field of chemical education utilize the conceptual framework of three distinct tiers that underlie the instruction and acquisition of chemical knowledge. This framework is commonly depicted in a chemistry triangle, with the vertices denoted as macroscopic, submicroscopic, and symbolic. The ability of students to…

Mediation analyses are crucial for understanding the mechanisms through which interventions or theoretical constructs influence outcomes within nested structures, commonly found in education, psychology, and sociology. Recognizing the importance of these effects, designing and analyzing robust studies to detect them is essential. This dissertation…

Generated information is better recognized and recalled than information that is read. This generation effect has been replicated several times for different types of material, including texts. Perhaps the most influential demonstration is by McDaniel, Einstein, Dunay, and Cobb ("Journal of Memory and Language," 1986, 25(6), 645-656;…

How should Deweyan educators teach their students about engaging in efforts to bring about social change in a political context marked by polarization, power differentials, and oppression? In this article, Joshua Forstenzer argues that Deweyan educators must encourage their students to engage in pluralistic and creative experiments rather than…

Laboratory experience is vital to undergraduate science education. It allows students to observe and conduct engaging experiments to enhance their skills and literacy, helps them retain knowledge, and deepens their understanding of related content covered in lectures. This paper reports a 4-week undergraduate laboratory exercise on…

To effectively demonstrate the transformation of ethanol into acetaldehyde, a simple, low-cost, and eco-friendly reaction demonstration was designed, in which a Y-shaped tube served as the reactor, condenser, and detector with the help of specific reagents. The ethanol was added via a transparent elephant nose spray bottle fixed to the top of the…

The chromatographic separation of plant pigments is one of the most popular and visually appealing experiments encountered by young scientists when they are introduced to the principles of analytical chemistry. As such, it has found widespread application in schools, public engagement activities, and undergraduate laboratories. However, most of…

Undergraduate physics laboratory exercises are very important in shaping students' attitude to science, especially for future teachers. Recently, it is necessary to look for ways to easily create large quantities of experimental sets, not only for institutional use, but also for sets that can be produced in large quantities and distributed for use…

Chemical reasoning takes many forms. The focus in this paper is on a reasoning process that facilitates using experimental evidence to make connections between macroscopic and submicroscopic domains, which we will refer to as "creating representation." It is a particular type of reasoning that has played a critical role in chemistry,…
