Here's what I've been up. Projects are in reverse chronological order.
PERbites is a site devoted to making the results of physics education accessible to those outside of the PER community. The site is one of about a dozen in the ScienceBites community, which consists of graduate students and postdocs from around the world working to present their research fields in understandable ways to those outside of the field.
Applying Machine Learning to Educational Data sets (Michigan State University)
Machine learning is a powerful analysis technique for large and complex data sets. I'm currently applying a random forest classification algorithm to data regarding uses of computation in physics curriculum.
Student Understanding of Period, Frequency, and Angular Frequency (The Ohio State University)
In this project, I investigated student difficulties with determining the period, frequency, and angular frequency from graphical and mathematical representations. The goals of this project were to determine what these difficulties are, determine if the skills needed to answer period, frequency, and angular frequency are arranged hierarchically, and determine if any found difficulties can be overcome with limited skills practice.
Photonics Careers Project (Rochester Institute of Technology)
The goal of this project is to understand how technicians, engineers, and researchers transition from school to the workplace. I specifically focused on how math is used in the workplace.

C3PO: Customizable Computer Coaches for Physics Online (University of Minnesota)
C3PO builds off of the University of Minnesota's previous problem solving work to construct online coaches to help students solve specific, context-rich problems based on their problem solving technique. My role in the project was to update one of the version 1 oscillatory motion coaches, which used a linear progression through the problem, into a version 2 coach, which use a nonlinear structure and allow the student to take alternative routes to the solution.
To learn more and try out some of the coaches, head to the C3PO coach interface .
