Proteins are "magical" workers inside our body, as they accomplish most of the cellular functions. Here we report on a novel approach to teach protein folding and unfolding, using magnets and flexible 3D-printed protein structures. To illustrate this physical process, we used colored circular magnets designed for whiteboards, connected…

The use of radioactive isotopes in radioactive decay studies can be a problem due to the manipulation of radioisotopes, expensive equipment, and the difficulty of finding samples with a reasonable half-life (between 1 and 10 min). In this paper, we present a mock-up of a Geiger-Mu¨ller counter plus three fictitious radioisotopes. They form an…

We propose an apparatus that emulates the experiment used by Geiger and Marsden in 1913 to investigate alpha particles (Rutherford) scattering. Using a widely available fused deposition modelling 3D-printer, we built a compartmented and easily assembled educational instrument. The whole apparatus is composed of a 3D-printed chamber and an…

Virtual reality (VR) has evolved to include non-immersive to fully-immersive experiences for the classroom. This study seeks to understand the potential effects VR may offer, specifically characteristics associated with how a student experiences a VR intervention and the effects of using a VR device for learning. A group experimental design was…

For centuries, cadaveric dissection has been the touchstone of anatomy education. It offers a medical student intimate access to his or her first patient. In contrast to idealized artisan anatomical models, it presents the natural variation of anatomy in fine detail. However, a new teaching construct has appeared recently in which artificial…

This study evaluated whether four persons (two groups) with developmental disabilities would be able to improve their collaborative pointing performance through a Multiple Cursor Automatic Pointing Assistive Program (MCAPAP) with a newly developed mouse driver (i.e., a new mouse driver replaces standard mouse driver, and is able to…

The Comprehensive Unified Physics Learning Environment is a computer system using computer programs, interactive videodisks, and electronic sensors being developed at the University of Maryland. The method has been found more effective than traditional ones for teaching physics majors and is being used to modify the conventional course for…
