I am a Professor of Information Sciences and Technology, and Affiliate Professor of Instructional Systems in the College of Education. With Dr. John Carroll, I co-direct the Computer-Supported Collaboration and Learning (CSCL). I am also a founding member of PSU's Center for Human-Computer Interaction, a loosely coupled university-wide consortia of researchers and educators pursuing topics in HCI.
My long-term research themes include scenario-based design (SBD) and evaluation methods, materials and tools for informal and collaborative learning, and interactive tools for software design and construction. An overview of the SBD methods can be found in the Usability Engineering textbook I wrote in 2002 as well as our repository of case studies.
Currently I am participating in a broad range of research projects, most involving some aspect of collaborative learning and problem solving. Typically our projects use a mix of methods - lab studies, participatory analysis and design, exploratory software development, and field studies within the general framework of action research.
Within the CSCL, I direct the ILSD group (Informal Learning in Software Development). We are studying a variety of end-user software construction tasks, with a focus on web application design, development, and debugging. We are also starting to work with younger learners, for example middle and high school girls who are first learning about programming.
I am a founding member of the EUSES Consortium (End Users Shaping Effective Software), a group of researchers from Oregon State, CMU, Drexel, University of Nebraska, and Penn State, who collaborate on a broad range of issues and techniques related to end-user software engineering. I am a member of the CHI Academy and an ACM Distinguished Scientist.
