Cooperative learning takes many forms and definitions, but most cooperative approaches
involve small, heterogeneous teams, usually of four or five members, working together towards a group task in which
each member is individually accountable for part of an outcome that cannot be completed unless the members work together;
in other words, the group members are positively interdependent. A vivid example of interdependence can be found in
the relationship between language-minority and language-majority students in two-way immersion programs. Native and non-native
English speakers work together to become bilingual.
