The document describes several collaborative learning techniques: group work, where small groups work together on tasks; brainstorming, where groups generate many ideas to open-ended problems; discussion, which allows open exchange of opinions without fear; debate, where two sides formally present arguments on an issue; panel, where a few students present information to a group; simulation, where students take on different roles to understand others' perspectives; role playing, where students act out scenarios to explore attitudes; focused conversation, where one or two students discuss a view while others listen; and peer review, where groups provide feedback to improve each other's work.
