Abstract
When students are learning collaboratively, they may engage in a variety of di erent
discourses. Students who are trying to understand a text may elaborate on each other’s
statements about what the text means. Students solving mathematics problems may give
each other answers or state a series of steps to follow. Another prominent form of discourse is argumentation, which involves taking positions, making claims, and giving
reasons and evidence for claims that are made. O en, although not always, argumentation will involve some disagreement and participants will take and defend di erent
positions. In this chapter, we discuss learning through a speci c form of this discourse,
which we call collaborative argumentation.
