Our Solution: MessageGrid





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, …
