However, it's possible that it refers to:
* Established communication channels: This could include:
* Teacher-student communication: The typical ways teachers interact with students (lectures, discussions, question-and-answer sessions, etc.).
* Student-teacher communication: How students express their understanding, ask questions, and share ideas with the teacher.
* Student-student communication: Peer-to-peer interaction in group activities, projects, or discussions.
* Pre-determined communication protocols: This could be about specific rules or guidelines about how to communicate in the classroom. For example:
* Raising hands to speak.
* Using a specific signal to indicate confusion or needing clarification.
* Following a designated process for asking questions.
To understand what "known classroom communication" means in your specific context, you need to provide more information. For example, tell me:
* Where did you hear this phrase?
* What was the context of the discussion?
With more details, I can provide a more accurate and helpful answer.
