Book clubs involve different roles including a monitor who asks comprehension questions and explains important parts of the book, a facilitator who participates in conversation and keeps it focused, and a coach who is removed from conversation but may provide reminders and teach specific reading skills outside of discussion. Getting started with book clubs requires changing where you sit, restating what students say without adding new ideas, prompting students by whispering, observing discussions, and teaching skills/strategies before discussion using a different book.
