Research Interests

Professor Vander Zanden's research focuses on two areas:

1. innovative teaching approaches in the classroom, especially in introductory programming courses. Specifically, Professor Vander Zanden is experimenting with flipped classroom approaches in both his lower and upper division courses. He has developed two website teaching tools, Code Assessor and the C++ Visualizer, which allow him to give students in-class programming exercises and immediate feedback on their efforts.
2. power reduction in mobile devices: Professor Vander Zanden is examining how modifying the way in which mobile device operating systems handle events could lead to less battery consumption by allowing the CPU to sleep longer. Specifically he is looking at how existing polling loops that continuously rouse the CPU in order to poll input devices for events could be replaced with a "push" model that only rouses the CPU when an event arrives at an input device. Such a "push" model would allow the CPU to sleep between events, whereas the existing "pull" model continuously rouses the CPU, even if there are no events pending on any input device.

• Participated with Wallace Mayo in the revision of the introductory computer science programming course (CS 102): 1993-1994. The emphasis of this revision was on creative problem solving.

• Significantly revised the computer graphics course (at the time labeled CS 460): 1990-1991. The emphasis of this revision was on bringing current developments in computer graphics into the classroom and in exposing students to cutting-edge software in computer graphics.

• Designed a ``finishing school for programmers'' course that served as a capstone experience for senior level undergraduate students in computer science. This course required students to work together on various research projects and emphasized the synthesis of ideas from the sprectrum of computer science courses they had previously taken.

• Chair of the committee, and principal designer of the CS undergraduate curriculum revision in 2009-2010.
