A reference electrode is an essential component of all three-electrode electrochemical measurements. Common commercial reference electrodes, including the saturated calomel electrode and Ag/AgCl reference electrode, are expensive with the former containing toxic mercury. Cheaper alternatives have been proposed including Ag/AgCl references made…

Systemic gender inequality and sexual discrimination continues across a wide spectrum of social, political, and economic fields. Using three key feminist curriculum and pedagogy principles (decentering norms, centering difference, distributing leadership) we employ feminist pedagogy by facilitating curriculum development and implementation that is…

The aim of this study is to evaluate a 3D (Three Dimensional) Traditional Chinese Medicine (TCM) e-learning platform and determine the factors affecting students' intention to continue to use the platform in TCM courses. Students from two classes were invited to participate in the experiment. To compare the effectiveness of both learning methods,…

Using tangible models to help students visualize chemical structures in three dimensions has been a mainstay of chemistry education for many years. Conventional chemistry modeling kits are, however, limited in the types and accuracy of the molecules, bonds and structures they can be used to build. The recent development of 3D printing technology…

Hands-on experiences in biomechanics and biomaterials courses are an important part of biomedical engineering education. Curricula of those courses often include laboratory modules on material testing and characterization. Unfortunately, large and expensive mechanical testing equipment may not be available to all students, thus limiting students'…

More and more schools are acquiring advanced manufacturing equipment. Activities that incorporate the use of this equipment for the purpose of teaching some academic content can either be designed or redesigned for other educational purposes as well. This article describes how the authors extended an activity that was initially designed to help…

This study focuses on the use of American Invention Kits from the Smithsonian Institute in conjunction with a 3D printer. In conjunction with a large dataset from a study funded by the National Science Foundation (NSF), this innovative research focuses on the effect the digital fabrication curriculum unit has on gifted and talented students'…

There is an increasing emphasis on fundamental particles, including quarks, in the high school physics classroom. However, many teachers might not feel comfortable teaching particle physics because it is a highly abstract and complex topic, and there are few hands-on activities to help teachers bring it into the classroom. In 2010, a…

The Mathematics, 3D Printing, and Computational Thinking Through Work-Based Learning (MPACT) program relies on teacher professional development, specialized curriculum and materials, and STEM industry mentors to provide grades 4-7 students with project-based experiences implemented across three learning modules. This technical report presents…

The Mathematics, 3D Printing, and Computational Thinking Through Work-Based Learning (MPACT) program combines teacher professional development, specialized curriculum and materials and STEM industry mentors to provide grade 4-7 students with project-based experiences implemented across three learning modules. This technical report presents…

Two material 3D printing is becoming increasingly popular, inexpensive and accessible. In this paper, freely available printable files and dual extrusion fused deposition modelling were combined to create a number of functional anatomical models. To represent muscle and bone FilaFlex[superscript 3D] flexible filament and polylactic acid (PLA)…

While many students may struggle to make sense of a mathematical formula and its practical implications, they can benefit greatly from an intuitive visualization and the engineering application of the topic. Effective STEM programs create clear connections at least with two subject areas, which translates into an enhanced student learning…

Health concerns from 3D printing were first documented by Stephens, Azimi, Orch, and Ramos (2013), who found that commercially available 3D printers were producing hazardous levels of ultrafine particles (UFPs) and volatile organic compounds (VOCs) when plastic materials were melted through the extruder. UFPs are particles less than 100 nanometers…

The 2020 pandemic involving SARS-CoV-2 (COVID-19) resulted in a rapid shift to online education for instructors at every level around the world. This shift occurred with little training and minimal resources available due to the rapidity of onset. In this technology report, we describe the use of 3D printing to rapidly manufacture mounts for…

3D design software is a commonly used interactive learning tool in STEM education. It is generally believed that 3D design can effectively train students' spatial thinking and engineering design abilities. There have been many theoretical and practical achievements in the application of 3D printing education, but the evaluation of 3D design is…
