Eliciting student participation in large college classes is noto-
riously difficult yet critical to learning. This paper describes
a design experiment with a computer-mediated feedback
system for promoting class interaction. We delineate spe-
cific challenges to interaction and propose design principles
to address them in computer-mediated systems. A prototype
realizing these principles establishes a computer-mediated
channel for student-initiated feedback. Students position
preset annotations (e.g., SLOW DOWN, EXPLAIN) directly
on the lecture slides. The system presents an anonymized
summary to the instructor in real time. An experiment in a
large class validates our design and suggests new lessons for
