Raman spectroscopy is an important vibrational spectroscopy tool to characterize chemical compounds. As only a few photons undergo Raman scattering, enhancement of signal is a vital requirement. In this laboratory experiment, some practical aspects of Raman spectroscopy and how a simple enhancement procedure can be used to detect a Raman signal…

The objective of this study was to examine the effectiveness of blended physics laboratory experimentation on pre-service physics teachers' (PSPTs') understanding of the nature of science (NOS) during an electricity and magnetism laboratory course. The study used a non-equivalent comparison group using a pre-test-post-test quasi-experimental…

At Kansas City University, anatomy laboratories were delivered via remote (REM) or on-campus (OC) formats due to COVID-19, creating an opportunity to evaluate student perceptions of differences in laboratory delivery format. A six-item survey of Likert scale and open-ended questions explored the utility of anatomy software, prelab instruction…

This study investigates the challenge faced by eighth-grade students at Southern State Middle School in grasping abstract concepts within the domains of physical science, physics, and chemistry. This difficulty is manifested in their poor performance on summative assessments. A comprehensive analysis of state-provided data, in conjunction with…

The Clemmensen reduction is a common example of a reaction demonstrating the deoxygenation of carbonyl groups, which is a topic that has been widely studied in the field of organic chemistry. The use of trimethylchlorosilane, as a substitute for concentrated hydrochloric acid, allows for the reduction of carbonyl groups. The Clemmensen reduction…

Hands-on learning activities enhance course outcomes in college courses based on increased exam scores and student satisfaction; however, online courses pose challenges for creating hands-on learning opportunities. The objective of this study was to compare online and on-campus students' perception and performance on a soybean processing and…

The supplementation of lecture-based anatomy teaching with laboratory sessions, involving dissection or anatomical specimens, is commonly used. Hands-on dissection allows students to handle instruments correctly while actively exploring three-dimensional anatomy. However, dissection carries a potential risk of sharps and splash injuries. The aim…

This study examined whether answering focused explanative questions during pauses in an immersive virtual reality (IVR) lesson on pipetting procedures could enhance learning. The goal was to take a generative learning activity, known to be effective for declarative knowledge with conventional media, to the context of procedural knowledge with…

A simple demonstration adaptable to classroom conditions is presented, which involves the preparation of raffle tickets using filter paper and the solution of selected fluorophores. With an appropriate dilution, the text written on the tickets is not visible to the naked eye; however, it becomes readable once put under a UV lamp. Besides being a…

Academic writing is an important skill in the development of researcher identity yet remains a hurdle to many. In this study, we examine the ways in which the exchange of social capital occurs in a writing group in Australia. We use Bourdieu's theoretical concepts to examine data obtained from open-ended questions in an online survey that asked…

Anatomy is a required curricular component within physician assistant (PA) programs, but the Accreditation Review Commission on Education for the Physician Assistant (ARC-PA) does not regulate specific course characteristics such as how or when anatomy is taught or the inclusion or type of specific laboratory approaches. The growing number of…

This article describes an exercise for a physical laboratory experiment designed to enable physical geography students to practice transferable quantitative skills through inquiry-based learning. The exercise is a deliberately simplified physical model of storm-driven coastal overwash typical of low-lying coastal barrier systems. The experiment…

This mixed-methods study sought to better understand how confidence in writing and race interact as factors within writing centers. Students utilizing our writing center were asked to provide data about racial identity and writing confidence both when registering with the writing center and when completing postsession surveys. From this data, we…

The purposes of the study were to examine the effectiveness of small-scale chemistry laboratory kits on chemistry preservice teachers' teaching competencies and to examine the effectiveness of small-scale chemistry laboratory kits on learners' science competencies. The target group consisted of (1) 20 fourth-year preservice chemistry teachers who…

Anatomy education in the undergraduate medical curriculum faces many competing interests, including the increasing demand for ultrasound learning. Instead of being treated as a separate subject, ultrasound can offer a unique lens to visualize anatomy without using cadaveric materials. This study used a randomized controlled design to compare…
