Framework for Evaluating Simulations: Analysis of Student Developed Interactive Computer Tools
21 Jul 2014  Papers  Contributor(s): Kelsey Joy Rodgers, Heidi A DiefesDux, Krishna Madhavan
Computer simulations are discussed in the learning environment from two major perspectives: 1) teaching students how to build simulations and 2) developing simulations to teach students targeted concepts. This study is approaching learning with simulations from a different perspective. We are interested in how students’ understandings of simulations develop through an iterative design challenge that requires them to create their own simulations. We investigated what firstyear...

FirstYear Engineering Students' Communication of Nanotechnology Size & Scale in a Design Challenge
22 Apr 2014  Papers  Contributor(s): Kelsey Joy Rodgers, Yi Kong, Heidi A DiefesDux, Krishna Madhavan
While nanotechnology is a highly engaging topic for students, it entails concepts that are difficult to understand and need to be carefully considered when incorporating nanotechnology into classroom instruction. The notion of size and scale (also referred to as a “big idea” in learning nanoscale engineering & science) is a fundamental concept for understanding nanotechnology, but is also a difficult concept for students to grasp. This study was guided by the following research question: …
