Cooperative learning is an educational approach which aims to organize classroom activities into academic and social learning experiences. There is much more to cooperative learning than merely arranging students into groups, and it has been described as "structuring positive interdependence." Students must work in groups to complete tasks collectively toward academic goals. Unlike individual learning, which can be competitive in nature, students learning cooperatively can capitalize on one another's resources and skills (asking one another for information, evaluating one another's ideas, monitoring one another's work, etc.). Furthermore, the teacher's role changes from giving information to facilitating students' learning. Everyone succeeds when the group succeeds. Ross and Smyth (1995) describe successful cooperative learning tasks as intellectually demanding, creative, open-ended, and involve higher-order thinking tasks. Cooperative learning has also been linked to increased levels of student satisfaction.

Five essential elements are identified for the successful incorporation of cooperative learning in the classroom:Johnson, D. W., Johnson, R. T., & Holubec, E. J. (1994). The nuts and bolts of cooperative learning. ^ eMinnesota Minnesota: Interaction Book Company. positive interdependence individual and group accountability promotive interaction (face to face) teaching the students the required interpersonal and small group skills group processing. According to Johnson and Johnson's meta-analysis, students in cooperative learning settings compared to those in individualistic or competitive learning settings, achieve more, reason better, gain higher self-esteem, like classmates and the learning tasks more and have more perceived social support.

History Prior to World War II, social theorists such as Allport, Watson, Shaw, and Mead began establishing cooperative learning theory after finding that group work was more effective and efficient in quantity, quality, and overall productivity when compared to working alone.Gilles, R.M., & Adrian, F. (2003). Cooperative Learning: The social and intellectual Outcomes of Learning in Groups. London: Farmer Press. However, it wasn't until 1937 when researchers May and DoobMay, M. and Doob, L. (1937). Cooperation and Competition. New York: Social Sciences Research Council found that people who cooperate and work together to achieve shared goals were more successful in attaining outcomes, than those who strived independently to complete the same goals. Furthermore, they found that independent achievers had a greater likelihood of displaying competitive behaviors.

Philosophers and psychologists in the 1930s and 1940s such as John Dewey, Kurt Lewin, and Morton Deutsh also influenced the cooperative learning theory practiced today. Dewey believed it was important that students develop knowledge and social skills that could be used outside of the classroom, and in the democratic society. This theory portrayed students as active recipients of knowledge by discussing information and answers in groups, engaging in the learning process together rather than being passive receivers of information (e.g., teacher talking, students listening).

Lewin's contributions to cooperative learning were based on the ideas of establishing relationships between group members in order to successfully carry out and achieve the learning goal. Deutsh's contribution to cooperative learning was positive social interdependence, the idea that the student is responsible for contributing to group knowledge.

Since then, David and Roger Johnson have been actively contributing to the cooperative learning theory. In 1975, they identified that cooperative learning promoted mutual liking, better communication, high acceptance and support, as well as demonstrated an increase in a variety of thinking strategies among individuals in the group.Johnson, D., Johnson, R. (1975). Learning together and alone: cooperation, competition, and individualization. Englewood Cliffs, NJ: Prentice-Hall. Students who showed to be more competitive lacked in their interaction and trust with others, as well as in their emotional involvement with other students.

In 1994 Johnson and Johnson published the five elements (positive interdependence, individual accountability, face-to-face interaction, social skills, and processing) essential for effective group learning, achievement, and higher-order social, personal and cognitive skills (e.g., problem solving, reasoning, decision-making, planning, organizing, and reflecting).Johnson, D., Johnson, R. (1994). Learning together and alone: cooperative, competitive, and individualistic learning. Needham Heights, MA: Prentice-Hall.

Theoretical base Social interdependence theory: Social interdependence exists when the outcomes of individuals are affected by their own and others' actions. There are two types of social interdependence: positive (when the actions of individuals promote the achievement of joint goals) and negative (when the actions of individuals obstruct the achievement of each other's goals). Social interdependence may be differentiated from social dependence, independence, and helplessness. Social dependence exists when the goal achievement of Person A is affected by Person B's actions, but the reverse is not true. Social independence exists when the goal achievement of Person A is unaffected by Person B's actions and vice versa. Social helplessness exists when neither the person nor other can influence goal achievement.

Kurt Lewin proposed that the essence of a group is the interdependence among members that results in the group being a dynamic whole so that a change in the state of any member or subgroup changes the state of any other member or subgroup. Group members are made interdependent through common goals. As members perceive their common goals, a state of tension arises that motivates movement toward the accomplishment of the goals.

Morton Deutsch extended Lewin's notions by examining how the tension systems of different people may be interrelated. He conceptualized two types of social interdependence—positive and negative. Positive interdependence exists when there is a positive correlation among individuals' goal attainments; individuals perceive that they can attain their goal if and only if the other individuals with whom they are cooperatively linked attain their goals. Positive interdependence results in promotive interaction. Negative interdependence exists when there is a negative correlation among individuals' goal achievements; individual perceive that they can obtain their goals if and only if the other individuals with whom they are competitively like fail to obtain their goals. Negative interdependence results in oppositional or content interaction. No interdependence exists when there is no correlation among individuals' goal achievements; individuals perceive that the achievement of their goals is unrelated to the goal achievement of others. The basic premise of social interdependence theory is that how participants' goals are structured determines the ways they interact and the interaction pattern determine the outcomes of the situation.

Types Formal cooperative learning is structured, facilitated, and monitored by the educator over time and is used to achieve group goals in task work (e.g. completing a unit). Any course material or assignment can be adapted to this type of learning, and groups can vary from 2-6 people with discussions lasting from a few minutes up to an entire period. Types of formal cooperative learning strategies include: The jigsaw technique Assignments that involve group problem-solving and decision making Laboratory or experiment assignments Peer review work (e.g. editing writing assignments). Having experience and developing skill with this type of learning often facilitates informal and base learning.Johnson, D., Johnson, R., & Holubec, E. (1988). Advanced Cooperative Learning. Edina, MN: Interaction Book Company. Jigsaw activities are wonderful because the student assumes the role of the teacher on a given topic and is in charge of teaching the topic to a classmate. The idea is that if students can teach something, they have already learned the material.

Informal cooperative learning incorporates group learning with passive teaching by drawing attention to material through small groups throughout the lesson or by discussion at the end of a lesson, and typically involves groups of two (e.g. turn-to-your-partner discussions). These groups are often temporary and can change from lesson to lesson (very much unlike formal learning where 2 students may be lab partners throughout the entire semester contributing to one another's knowledge of science).

Discussions typically have four components that include formulating a response to questions asked by the educator, sharing responses to the questions asked with a partner, listening to a partner's responses to the same question, and creating a new well-developed answer. This type of learning enables the student to process, consolidate, and retain more information.

In group-based cooperative learning, these peer groups gather together over the long term (e.g. over the course of a year, or several years such as in high school or post-secondary studies) to develop and contribute to one another's knowledge mastery on a topic by regularly discussing material, encouraging one another, and supporting the academic and personal success of group members.

Base group learning (e.g., a long-term study group) is effective for learning complex subject matter over the course or semester and establishes caring, supportive peer relationships, which in turn motivates and strengthens the student's commitment to the group's education while increasing self-esteem and self-worth. Base group approaches also make the students accountable to educating their peer group in the event that a member was absent for a lesson. This is effective both for individual learning, as well as social support.

Elements Johnson and Johnson (2009) posited five variables that mediate the effectiveness of cooperation. Brown & Ciuffetelli Parker (2009) and Siltala (2010) discuss the 5 basic and essential elements to cooperative learning:Siltala, R. (2010). Innovativity and cooperative learning in business life and teaching. University of Turku. The first element is positive interdependence. Students must fully participate and put forth effort within their group, and each group member has a task, role or responsibility, therefore must believe that they are responsible for their learning and that of their group. The second element is face-to-face promotive interaction. Members must promote each other's success, and students explain to one another what they have or are learning and assist one another with understanding and completion of assignments. The third element is individual and group accountability. Each student must demonstrate mastery of the content being studied and each student is accountable for their learning and work, therefore eliminating social loafing. The fourth element is social skills, which must be taught in order for successful cooperative learning to occur. The skills include effective communication and interpersonal and group skills. For example, leadership, decision-making, trust-building, friendship-development, communication, and conflict-management skills. The fifth element is group processing. Group processing occurs when group members reflect on which member actions were helpful and make decisions about which actions to continue or change. The purpose of group processing is to clarify and improve the effectiveness with which members carry out the processes necessary to achieve the group's goals.
