11 Nov 2014 | Papers | Contributor(s): Yi Kong, Heidi A Diefes-Dux, Kelsey Joy Rodgers, Anna Douglas, Krishna Madhavan

The concepts of size and scale are fundamental to nanotechnology education but can be difficult for beginning undergraduate students to grasp. It is important to develop curricular interventions to increase students’ conceptual understanding of size and scale, before moving on to more...

Framework for Evaluating Simulations: Analysis of Student Developed Interactive Computer Tools

21 Jul 2014 | Papers | Contributor(s): Kelsey Joy Rodgers, Heidi A Diefes-Dux, 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...

Sample Assessment Rubric

17 Jun 2014 | Teaching Materials | Contributor(s): Heidi A Diefes-Dux, Krishna Madhavan, Kelsey Joy Rodgers

This is an assessment rubric that we used in Spring 2013 to assess students' projects. This particular rubric was used to assess submissions for Milestones 4,5, 6, 8, and 9.

Sample Memo to Introduce Students to the Projects

This is a memo that we used in Spring 2013 to introduce students to their assigned project. It contains a brief introduction to nanoHUB.org and nanotechnology, a list of criteria, a list of milestones, and some learning objectives.

First-Year Engineering Students' Communication of Nanotechnology Size & Scale in a Design Challenge

22 Apr 2014 | Papers | Contributor(s): Kelsey Joy Rodgers, Yi Kong, Heidi A Diefes-Dux, 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...

Displays drain current as a function of source-drain voltage for different values of gate voltage, gate dimensions, substrate material, and oxide material in an n-type MOSFET.

High Quality Mathematical Model Solutions

26 Jul 2013 | Animations | Contributor(s): Heidi A Diefes-Dux, Kelsey Joy Rodgers, Paul Branham, Krishna Madhavan

This is the third of three modules on Model-Eliciting Activities. (This is referred to as MEA video 3 on DAY 3 Training. This should be watched prior or during DAY 3 Training.)

Problem Formulation & Problem Identification

This is the second of three modules on Model-Eliciting Activities. (The DAY 1 Training presentation refers to this as the MEA 2 video. This video should be watched during or before DAY 1 Training.)

Mathematical Models & Model Development Process
