As some say that all students should be required to “speak up” in class, I say “let them type.” If you run a backchannel, that should count as classroom contribution. I’ve found that quieter students will float an idea in the classroom and are willing to express it verbally if the teacher notices and speaks about the topic. Sometimes students want a low-threat way to suggest and interject, and I’ve personally found the backchannel to be a powerful way to do this.
