Physics teachers are often faced with the challenge of having to set up difficult experiments, or they have to consciously manipulate parameters in order to be able to demonstrate a phenomenon convincingly. Comprehensive laboratory courses are standard procedure in any study program for prospective physics teachers. However, many students, even…

Practical work as observation and experimentation are vital parts of science education. One way to accomplish this is by applying inquiry-based learning in laboratory activities. Inquiry enhances the development of scientific skills as well as the learning of the scientific concepts. In the present article, a laboratory activity was developed to…

A dual-function student-crafted instrument is described as part of a laboratory activity aimed to teach both the principles and practical aspects of absorption spectroscopy to secondary and introductory undergraduate students. Using minimal changes in an arrangement that is based on interlocking bricks and low-cost components, both a fluorometer…

Laboratory studies are very important for science education but also involve various risks. It is possible to minimize these risks by providing a safe working environment. This study aims to determine the knowledge and views of secondary school students on laboratory safety and to identify their deficiencies in this regard. The survey method was…

This experiment combines analytical techniques of solid-phase extraction (SPE) and gas chromatography quadrupole time-of-flight mass spectrometry (GC-QTOF-MS) to determine organochlorine pesticides (OCPs) in river water as a means to develop and improve student understanding of the use of GC-QTOF-MS for qualitative and quantitative analysis. In…

Organic electrosynthesis is an increasingly popular tool for driving and probing redox reactions. Recent advances in this field often employ an electrocatalyst to enhance the selectivity and efficiency of electrochemical reactions. A laboratory experiment was developed to introduce students to relevant mechanistic techniques in electrochemistry…

In an idealized General Chemistry Laboratory curriculum, students would hone their experimental design ability with practice encouraged by laboratory exercises designed to be open-ended. However, traditional General Chemistry Laboratory courses often lack opportunities for students to design their own experiments, instead opting to provide…

Highly efficient microwave-assisted organic synthesis is now commonplace in both industry and academia. Recently, a conductively heated sealed-vessel reactor was introduced that acts very similarly to a microwave reactor and is more affordable. Application of such reactors in teaching laboratories is advantageous because of the restricted window…

Virtual reality (VR) technology has been widely used in nursing laboratory courses to effectively making up for the shortcomings of traditional teaching. However, challenges such as cell phone addiction, negative emotions, and reduced communication between teachers and students still exist during the application process, which makes it difficult…

Immersive virtual reality (IVR) is expected to create a greater sense of presence that might improve students' laboratory learning experiences. However, little research has verified the influence of presence on students' perceptions toward immersive laboratory learning. The current study, which is based on the expectation confirmation model,…

Heartwheels! STEM Mobile Outreach is a scientist-led collaborative, innovative, and reproducible experiential educational program and mobile lab developed to engage people young and old in the cardiovascular sciences, improve health literacy and awareness of heart-healthy living, and spark curiosity in the science, technology, engineering, and…

Background: In recent years, immersive virtual reality in education has garnered attention, however, there have been mixed findings on the efficacy of IVR in education. Thus, exploring which strategies are effective in transferring learning from IVR to real-world applications is imperative. Objective: This study aims to investigate the efficacy of…

This study explores the effectiveness of video demonstrations compared to live classroom visits for promoting writing center services to students in first-year writing courses. Using a randomized cluster experimental design, the researchers implemented either an in-person demonstration, a video demonstration, or no intervention (control). Pre- and…

Science, technology, engineering, and mathematics (STEM) students are typically taught content delivered didactically and closely aligned with the laboratory demonstration of concepts, which facilitates the development of experimental skills. Because of the volume of content delivered across multiple courses, student cognitive abilities can be…

This study was conducted in the laboratory and Metaverse environment with "Acids-Bases," a science subject related to the Metaverse, one of today's technologies. In line with the purpose of the research, the embedded design of the mixed research method, which combined quantitative and qualitative research methods, was used. The…
