The Hint Factory is a novel application to automatically generate contextualized hints and feedback from past student data. This work has received multiple awards including “Best Student Paper” at ITS 2010.
is the world's largest open data repository of educational data logs. The repository has data from thousands of students derived from interactions with on-line course materials and intelligent tutoring systems. I am Technical Director of DataShop.
My recent teaching responsibilities have centered around our Masters in Educational Technologies and Applied Learning Sciences (METALS). In Spring and Summer of 2015, I am co-teaching the Masters Capstone course, which pairs student teams with real clients to create products with real value!
This website describes my research and development activities. Please take a look around and feel free to contact me for more information on anything you see.
I earned my PhD in Computer Science at the University of North Carolina at Charlotte. My main area of research is focused on using "Big Data" from educational systems to improve learning. I generally publish in the areas of intelligent tutoring systems and educational data mining. I am also the lead researcher behind DataShop, which is the largest open repository of log data from learning systems. My PhD advisor was Dr. Tiffany Barnes. Prior to starting my PhD, I spent over ten years in the business world. Although I am still consulting, my most recent major position was Vice President of Development for VSI Technolgies, Inc. During this time I earned my MCSE (Microsoft Certified Systems Engineer) and MCDBA (Microsoft Certified Database Administrator) certifications. Recently, I have been involved in creating a new startup called TutorGen, which is looking to help build intelligent tutoring capabilities for existing educational technologies with the use of big data.
I am an avid collector of Arcade and Pinball machines. A somewhat outdated list of my collection of arcade games can be seen here. I am also a big fan of the obscure Vectrex game system that came out in 1982. This is a vector based game machine (like Asteroids or Tempest) that was released for home use. In addition to enjoying playing the games, I have created a few of my own games written entirely in Motorola 6809 Assembler language.
