We present the use of an oxygen tolerant controlled radical polymerization (photoinduced electron/energy transfer-reversible addition fragmentation chain transfer polymerization, PET-RAFT) as a simple method for preparing controlled radical polymers in an undergraduate laboratory. Unlike conventional techniques, PET-RAFT polymerizations require no…

Dendrite growth affects material systems across applications as diverse as lithium batteries, organic light emitting diodes, turbine blades, and biological sensors. Their unique crystal structure and ability to physically see growth make for a unique undergraduate laboratory experience. This experiment uses dendrite growth to explore the physical…

A simple, cheap, and easy to make ionisation chamber to investigate the decay of Radon-220. Requires no expensive meters, experiment is carried out using thoriated gas mantles to produce the Radon-220, and the chambers are used with low cost digital multimeters. An opportunity for 16-18 students to carry out a hands-on experiment with an ionising…

3D printing and simple electronics were used to create a polarimeter suitable for a variety of chemistry courses. This device allows instructors to demonstrate optical activity but is also easy to use and low cost enough to be widely available for student use, as well. The instrument uses an LED light source and detector housed in a 3D-printed…

We report a simple means to build a model atomic force microscope (AFM) using 3D printing of thermoplastic materials that are commercially available. The model has many of the key parts of an actual AFM including a z-axis stage, an AFM head with a cantilever assembly, and a laser source that reflects off of the back of the cantilever. Using a…

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…

Background/purpose: Empirical data consistently demonstrate that social sciences education suffers from suboptimal learning outcomes, primarily due to overcrowded curricula and students' struggle to connect abstract theoretical concepts with real-world applications. Therefore, learning that implements technology to assist students in comprehending…

Chemistry labs are often taught using a rote mechanical approach without much explicit scaffolding for academic reflection by the students. Reflection, however, can play an essential role in learning because it is an evidence-based learning process that generates, deepens, critiques, and documents learning. By moving away from traditional teaching…

CSU Writes supports researchers as writers across their career span at Colorado State University. The program emerged in an already rich writing ecosystem that includes a Writing Center and the WAC Clearinghouse. Since 2015, CSU Writes has helped thousands of faculty, postdoctoral fellows, and graduate students write more regularly, skillfully,…
