This document discusses various cooperative and collaborative learning techniques. It describes think-pair-share, where students individually think about a question, discuss their answers with a partner, and share with the class. The jigsaw technique divides a lesson into parts and assigns one part to each student to teach peers. Collaborative learning involves groups working together on a project through different stages from forming to performing. The learning circle is a highly interactive structure where students build and share knowledge through open dialogue and reflection to achieve a shared outcome. These techniques increase student engagement and help develop social skills.
