Exploring Students’ Epistemological Understanding Of Atomic Structure Models, Claire V. Ward, Morgan Balabanoff
The Cardinal Edge
Developing a robust understanding of atomic structure and the nature of matter is foundational across chemistry and STEM courses. The development of this concept is challenging because it relies on models to illustrate something not directly observable. Scientific models are important tools used to explain phenomena, particularly phenomena that are not directly observable. In general chemistry, students are typically asked to consider four different models: (1) the particle model, (2) the nuclear model, (3) the Bohr model, and (4) the Quantum model. Each depiction has its own advantages and limitations, where instructors introduce each model to explain specific parts of …

Purpose: While mass-produced anatomical models are commercially available, many models are inflexible and static, and may not meet the needs of health professions students. Advances in three-dimensional (3D) printing have demonstrated tremendous potential for enhancing student learning. This study uses 3D printed cervical spine models to explore whether use of dynamic, flexible models improve student learning in a cohort of physical therapy students. Methods: 3D printed models of the cervical spine and occiput were printed using a fused deposition modeling 3D printer and polylactic acid filament, and augmented with hook and loop fasteners, foam sheets, and cords to simulate structures …
