Abstract

In a collaborative learning environment, students often talk to each other as they construct knowledge together. Collaborative learning environments often go by names such as project-based learning (Krajcik & Blumenfeld, 2006), problem-based learning (Hmelo-Silver & DeSimone, chapter 21 this volume), or inquiry-based learning (e.g., Slotta & Linn, 2009; Wells & Arauz, 2006). The teacher works closely with student groups to provide appropriate support and necessary information about relevant facts and procedures as they work to solve problems or to pursue project goals. The teacher often facilitates or channels the discussion, but if students are collaborating effectively an experienced teacher may realize that the best thing to do is to stay silent.
