The latest developments in virtual reality (VR) are gaining attention in education as they are expected to provide risk-free, hands-on learning experiences. However, the use of VR in laboratory settings is still in its early stages of adoption. Therefore, it remains unclear whether these technologies will be widely adopted to educate students in…

With the increase of waste paper, environmental pollution and atmospheric impact have become global problems. The cellulose contained in waste paper has the advantages of being renewable and biodegradable and can be applied to many fields to achieve sustainable development. At present, thermal management materials, as a new type of material, have…

The chemistry laboratory can be a daunting place for first year university students, especially those entering one for the first time with little or no prior laboratory experience. Increasing financial constraints placed on secondary schools has restricted the ability to provide rich laboratory experiences for students before entering tertiary…

Educational laboratory management is a paramount issue in agricultural education settings. Agricultural mechanics laboratories are found in many agricultural education programs. One of the most important issues an instructor in agricultural education settings faces is safety in the agricultural mechanics laboratory. Identifying and cultivating a…

Chemistry laboratories ordinarily involve a number of visual observations and require qualitative and quantitative explanations of these observations. A student with blindness at Truman State University successfully completed the laboratory portion of the non-majors liberal arts chemistry course with the assistance of a senior undergraduate…

Regioselectivity in hetero Diels-Alder reactions can be observed in a simple reaction between a nonsymmetrical heterodiene and an unsymmetrical heterodienophile. A 9 h and easy to implement laboratory experiment is described, in which students can observe the regioselectivity of inverse "electron-demand" hetero Diels-Alder reactions of…

Typical laboratory exercises for undergraduate organic chemistry students involve bulk phase reactions with work up of product. In this study, students performed accelerated versions of the Katritzky reaction of para-substituted anilines with pyrylium salts in three ways: (i) by dropcasting reagents onto a paper surface and allowing solvent to…

Time-resolved luminescence lifetime measurements are an important photophysical technique. However, access to this technique at the undergraduate level is limited by the expense of the instrumentation needed to create the well-defined light pulses required to measure the luminescence decay of an excited state molecule. We present here an…

We built a low-cost and hand-held device to image and analyze microfluidic droplets mainly for educational/teaching purposes in laboratory settings of universities. The device was assembled based on a Raspberry Pi with a camera attached on the back and an LCD screen on the top. We evaluated the performance of this device to capture images and…

This paper examines the pedagogical integration of Virtual Microscopes (VMs) in Virtual Learning Environments (VLEs), to identify best practice and improve online pedagogy. It has captured the perspectives of 12 Health and Earth Science university teachers, through in-depth interviews, about the current integration of the VM in online teaching,…

This study presents a monocular approach for capturing students' prototyping activities and interactions in digital-fabrication-based makerspaces. The proposed method uses images from a single camera and applies object reidentification, tracking, and depth estimation algorithms to track and uniquely label participants in the space, extracting both…

Introductory biology courses at most colleges and universities have two components: a lecture and a lab. However, for students who are not majoring in biology and taking the introductory course as part of their general education requirements, the distinct role of the lab has not been clearly articulated. We performed an online modified-Delphi…

Purpose: March 2020 signaled school closures and moves online for many institutions, but an online EdD program at a midsize, Christian university featured fewer than-expected programmatic changes. Because of its modality, program operations continued with relatively few changes. Although COVID-19-related campus closures did not interrupt these…

This study investigated how human dissection affects students' spiritual beliefs, and how their existing spiritual beliefs influence their perceptions of human dissection. This cross-sectional study assessed 760 medical students with human dissection experience using an online questionnaire developed from interviews and the Spirituality…

This study investigates the impact of a STEM field trip on engagement in STEM learning and interest in STEM among students at a Historically Black College and University (HBCU) in Texas. Using Kolb's (1984) experiential learning model as a theoretical framework, the research explores how engaging, hands-on activities during the field trip enhance…
