Collaborative Learning Dynamics

Collaborative Learning:
Group Work and Study Teams

Faculty Strategies for Tutor Consideration

Students learn best when they are actively involved in the process. Researchers report that, regardless of the subject matter, students working in small groups tend to learn more of what is taught and retain it longer than when the same content is presented in other instructional formats. Students who work in collaborative groups also appear more satisfied with their classes.

Various names have been given to this form of teaching, and there are some distinctions among these: cooperative learning, collaborative learning, collective learning, learning communities, peer teaching, peer learning, reciprocal learning, team learning, study circles, study groups, and work groups. But all in all, there are three general types of group work: informal learning groups, formal learning groups, and study teams (adapted from Johnson, Johnson, and Smith, 1991).

Informal learning groups are ad hoc temporary clusterings of students within a single class session. Informal learning groups can be initiated, for example, by asking students to turn to a neighbor and spend two minutes discussing a question you have posed. You can also form groups of three to five to solve a problem or pose a question. You can organize informal groups at any time in a class of any size to check on students' understanding of the material, to give students an opportunity to apply what they are learning, or to provide a change of pace.

Formal learning groups are teams established to complete a specific task, such as perform a lab experiment, write a report, carry out a project, or prepare a position paper. These groups may complete their work in a single class session or over several weeks. Typically, students work together until the task is finished, and their project is graded.

Study teams are long-term groups (usually existing over the course of a semester) with stable membership whose primary responsibility is to provide members with support, encouragement, and assistance in completing course requirements and assignments. Study teams also inform their members about lectures and assignments when someone has missed a session. The larger the class and the more complex the subject matter, the more valuable study teams can be.

The suggestions below are designed to help you set up formal learning groups and study teams. If you have never done group work in your classes, you might want to experiment first with informal learning groups. Two other tools, "Leading a Discussion" and "Supplements and Alternatives to Lecturing: Encouraging Student Participation," describe a variety of easy ways to incorporate informal learning groups into your courses. "Helping Students Write Better in All Courses" discusses informal collaborative writing activities.

Plan for each stage of group work. Think about how you will organize students into groups, help groups negotiate among themselves, provide feedback to the groups, and evaluate the products of group work.

Carefully explain to your group how the groups will operate. As you would when making any assignment, explain the objectives of the group task and define any relevant concepts. In addition to a well-defined task, every group needs a way of getting started, a way of knowing when its task is done, and some guidance about the participation of members. Also explain how students will be graded. Keep in mind that group work is more successful when students are graded against a set standard than when they are graded against each other (on a curve). See "Grading Practices." (Source: Smith, 1986)

Give students the skills they need to succeed in groups. Many students have never worked in collaborative learning groups and may need practice in such skills as active and tolerant listening, helping one another in mastering content, giving and receiving constructive criticism, and managing disagreements. Discuss these skills with your students and model and reinforce them during class. Some faculty use various exercises that help students gain skills in working in groups (Fiechtner and Davis, 1992). See "Leading a Discussion" for examples of guidelines for participating in small groups. (Sources: Cooper, 1990; Johnson, Johnson, and Smith, 1991)

Create group tasks that require interdependence. The students in a group must perceive that they "sink or swim" together, that each member is responsible to and dependent on all the others, and that one cannot succeed unless all in the group succeed. Knowing that peers are relying on you is a powerful motivator for group work (Kohn, 1986). Strategies for promoting interdependence include specifying common rewards for the group, encouraging students to divide up the labor, and formulating tasks that compel students to reach a consensus. (Source: Johnson, Johnson, and Smith, 1991)

Make the group work relevant. Students must perceive the group tasks as integral to the course objectives, not just busywork. Some faculty believe that groups succeed best with tasks involving judgment. As reported by Johnson, Johnson, and Smith (1991), for example, in an engineering class, a faculty member gives groups a problem to solve: Determine whether the city should purchase twenty-five or fifty buses. Each group prepares a report, and a representative from each group is randomly selected to present the group's solution. The approaches used by the various groups are compared and discussed by the entire class. Goodsell, Maher, Tinto, and Associates (1992, pp. 75-79) have compiled a detailed bibliography of discipline-specific efforts in collaborative learning that can be useful for developing tasks and activities.

Create assignments that fit the students' skills and abilities. Early in the term, assign relatively easy tasks. As students become more knowledgeable, increase the difficulty level. For example, a faculty member teaching research methods begins by having students simply recognize various research designs and sampling procedures. Later, team members generate their own research designs. At the end of the term, each team prepares a proposal for a research project and submits it to another team for evaluation. (Source: Cooper and Associates, 1990)

Assign group tasks that allow for a fair division of labor. Try to structure the tasks so that each group member can make an equal contribution. For example, one faculty member asks groups to write a report on alternative energy sources. Each member of the group is responsible for research on one source, and then all the members work together to incorporate the individual contributions into the final report. Another faculty member asks groups to prepare a "medieval newspaper." Students research aspects of life in the Middle Ages, and each student contributes one major article for the newspaper, which includes news stories, feature stories, and editorials. Students conduct their research independently and use group meetings to share information, edit articles, proofread, and design the pages. (Sources: Smith, 1986; Tiberius, 1990)

Set up "competitions" among groups. A faculty member in engineering turns laboratory exercises into competitions. Students, working in groups, design and build a small-scale model of a structure such as a bridge or column. They predict how their model will behave when loaded, and then each model is loaded to failure. Prizes are awarded to the groups in various categories: best predictions of behavior, most efficient structure, best aesthetics. (Source: Sansalone, 1989)

Consider offering group test taking. On a group test, either an in-class or take-home exam, each student receives the score of the group. Faculty who have used group exams report that groups consistently achieve higher scores than individuals and that students enjoy collaborative test taking (Hendrickson, 1990; Toppins, 1989). Faculty who use this technique recommend the following steps for in-class exams:

• Assign group work at the beginning of the term so that students develop skills for working in groups.
• Use multiple-choice tests that include higher-level questions. To allow time for discussion, present about twenty-five items for a fifty-minute in-class exam.
• Divide students into groups of five.
• Have students take the test individually and turn in their responses before they meet with their group. Then ask the groups to arrange themselves in the room and arrive at a group consensus answer for each question. Score the individual and group responses and prepare a chart showing the average individual score of each group's members, the highest individual score in each group, and the group's consensus score. Ninety-five percent of the time, the group consensus scores will be higher than the average individual scores (Toppins, 1989).

Decide how the groups will be formed. Some faculty prefer randomly assigning students to groups to maximize their heterogeneity: a mix of males and females, verbal and quiet students, the cynical and the optimistic (Fiechtner and Davis, 1992; Smith, 1986). Some faculty let students choose with whom they want to work, although this runs the risk that groups will socialize too much and that students will self-segregate (Cooper, 1990). Self-selected groups seem to work best in small classes, for classes of majors who already know one another, or in small residential colleges (Walvoord, 1986). Still other instructors prefer to form the groups themselves, taking into account students' prior achievement, levels of preparation, work habits, ethnicity, and gender (Connery, 1988). They argue for making sure that members of each group are exclusively graded students or exclusively pass/ not pass students and that well-prepared students be placed in groups with other well-prepared students. Other faculty, however, try to sprinkle the more able students evenly among the groups (Walvoord, 1986). A middle ground, proposed by Walvoord (1986), is to ask students to express a preference, if they wish, then make the assignments yourself. You could, for example, ask students to write down the names of three students with whom they would most like to work.

Be conscious of group size. In general, groups of four or five members work best. Larger groups decrease each member's opportunity to participate actively. The less skillful the group members, the smaller the groups should be. The shorter amount of time available, the smaller the groups should be. (Sources: Cooper, 1990; Johnson, Johnson, and Smith, 1991; Smith, 1986)

Keep groups together. When a group is not working well, avoid breaking it up, even if the group requests it. The addition of the floundering group's members to ongoing groups may throw off their group process, and the bailed-out troubled group does not learn to cope with its unproductive interactions. (Source: Wolvoord, 1986)

Help groups plan how to proceed. Ask each group to devise a plan of action: who will be doing what and when. Review the groups' written plans or meet with each group to discuss its plan.

Regularly check in with the groups. If the task spans several weeks, you will want to establish checkpoints with the groups. Ask groups to turn in outlines or drafts or to meet with you.

Provide mechanisms for groups to deal with uncooperative members.

Walvoord (1986) recommends telling the class that after the group task is completed, each student will submit to the instructor an anonymous assessment of the participation of the other group members: who did extra work and who shirked work. If several people indicate that an individual did less than a fair share, that person could receive a lower grade than the rest of the group. This system works, says Walvoord, if groups have a chance in the middle of the project to discuss whether any members are not doing their share. Members who are perceived as shirkers then have an opportunity to make amends. Here are some other options for dealing with shirkers:

Keep the groups at three students: it is hard to be a shirker in a small group.

Make it clear that each group must find its own way to handle unproductive group behavior.

Allow the groups, by majority vote, to dismiss a member who is not carrying a fair share. Students who are dropped from a group must persuade the group to reconsider, find acceptance in another group, or take a failing grade for the project.

Perhaps the best way to assure comparable effort among all group members is to design activities in which there is a clear division of labor and each student must contribute if the group is to reach its goal. (Sources: Connery, 1988; Walvoord, 1986)
