post-question waits are often short, instructors may fill uncomfortable silence, and insufficient waiting or teacher interruption can limit response opportunities. Philosophy-specific guidance and practitioner evidence independently recognize monopolized discussion, recurring fast contributors, quiet students, and the value of pre-discussion thinking or writing.
