Implementing Tactile Learning to Aid Students Understanding of the Bohr Model

Abstract

It is essential for introductory level chemistry students to understand atomic models and how atoms interact to form chemical bonds. The tactile model in this article utilizes marbles to represent subatomic particles, a cup to represent the nucleus and wooden rings to simulate the electron orbitals. These inexpensive items can be combined to construct models in which students can build foundational knowledge of atomic structure and how subatomic particles interact. Students were asked to provide feedback comparing the use of this tactile model to atomic computer simulations, videos and their textbook regarding the method they felt was most useful to learn atomic structure.
