The Challenge
How can instructors use the laptop computers to advantage in and out of the classroom?
October 15, 2009 9Roy Pargas, Current Research USAFA 2009, Colorado Springs, CO
Web-based software tool to help promote interactivity in the classroom
Clemson’s Proposed Solution: MessageGrid
October 15, 2009 10Roy Pargas, Current Research USAFA 2009, Colorado Springs, CO
Web-based Basic grid: rows and columns Instructor designs grid Students post original submissions or
replies to submissions Anything displayed by a browser
• Text, image, audio, video, animation, Ink, maps Why use such a tool?
• Student responses to in-class exercises, presentations, online discussions, student questions, feedback from students, …
Proposed Solution: MessageGrid

MessageGrid Evolution
Every semester since January
2004, more instructors use MessageGrid
At semester’s end, instructors discuss possible improvements
Suggestions with most instructor
support are implemented
