Paraphrasing and asking questions.

Listening halfheartedly and not replying.

Tuning out the conversation altogether.

Quietly listening and nodding.

Confront them in front of the entire class?

Ask them what they want to be working on

Meet them personally to discuss their part in the team

Quietly remove their name from the assignment

Keeping an open mind while calmly trying to express how you feel.

Aggressively asserting your point.

Abandon the situation.

Disproving everything that clashes with your point.
