Liffiton Develops Free App for Teachers
Assistant Professor of Computer Science Mark Liffiton

BLOOMINGTON, Ill. – Teachers: want to know if your class understood the important
point you just made? There’s now a free and simple app for that.
Mark Liffiton, an Illinois Wesleyan University assistant professor of computer science,
has received a Google App Engine Education Award for developing TeacherTap, a free, simple-to-use classroom-response system. The application, a program that
runs inside another service, is built on the Google App Engine. TeacherTap lets students
give instant, anonymous feedback to teachers about a lecture or discussion from any
computer or mobile device with a web browser.
The app is available to anyone, anywhere at teachertap.appspot.com and could be useful in any situation in which a person wants quick, anonymous feedback,
such as a presentation during a conference, for example.
Liffiton said the idea came about because of growing interest in Classroom Response
Systems and the increasing potential for such systems to be run on existing devices
such as smartphones via the web instead of requiring dedicated electronics.
“Several similar applications have been developed, but none were quite what I wanted:
very basic, easy to use, and free,” said Liffiton. “TeacherTap is not an original
idea, but most of the others out there were either more complex or require payment
from the teacher or the students to use.”
Liffiton was also interested in developing TeacherTap to learn how to develop for
Google’s App Engine platform, allowing one to write web software that runs on Google’s
“App Engine lets a developer focus almost entirely on programming their application
without worrying about buying, setting up and managing the servers on which it runs,”
said Liffiton. His Google App Engine Education Award -- a $1,000 in-kind credit --
effectively allows TeacherTap to run for a full year for free.
TeacherTap was recently highlighted on the Google Developers Blog along with other App Engine Education Award winners from the University of Michigan,
Brown University, Rutgers and Wellesley College.
Liffiton received his Ph.D. in computer science and engineering from the University
of Michigan in 2009. He joined the faculty at Illinois Wesleyan the same year.
