Why we cap live voice channels during lab blocks
community · accessibility
Open microphones feel democratic until half the cohort is overstimulated. We schedule focused voice windows tied to specific exercises and keep async text for everything else.
Mentors rotate rather than stack. One voice per ten minutes of explanation keeps pacing crisp and gives quieter participants predictable airtime.
We also publish transcripts summaries after sessions—not raw logs—so people who process textually are not left behind.
That structure is imperfect, yet satisfaction scores climb when learners can predict where answers will appear.
