Many jigsaw teachers find it useful to appoint one of the students to be the discussion leader for each session, on a rotating basis. It is the leader's job to call on students in a fair manner and try to spread participation evenly. In addition, students quickly realize that the group runs more effectively if each student is allowed to present her or his material before question and comments are taken. Thus, the self interest of the group eventually reduces the problem of dominance.
Teachers must make sure that students with poor study skills do not present an inferior report to the jigsaw group. If this were to happen, the jigsaw experience might backfire (the situation would be akin to the untalented baseball player dropping a routine fly ball with the bases loaded, earning the wrath of teammates). To deal with this problem, the jigsaw technique relies on “expert” groups. Before presenting a report to their jigsaw groups, each student enters an expert group consisting of other students who have prepared a report on the same topic. In the expert group, students have a chance to discuss their report and modify it based on the suggestions of other members of their expert group. This system works very well. In the early stages, teachers may want to monitor the expert groups carefully, just to make sure that each student ends with an accurate report to bring to her or his jigsaw group. Most teachers find that once the expert groups get the hang of it, close monitoring becomes unnecessary.
Boredom can be a problem in any classroom, regardless of the learning technique being used. Research suggests, however, that there is less boredom in jigsaw classrooms than in traditional classrooms. Youngsters in jigsaw classes report liking school better, and this is true for the bright students as well as the slower students. After all, being in the position of a teacher can be an exciting change of pace for all students. If bright students are encouraged to develop the mind set of “teacher,” the learning experience can be transformed from a boring task into an exciting challenge. Not only does such a challenge produce psychological benefits, but the learning is frequently more thorough.
Research suggests that jigsaw has its strongest effect if introduced in elementary school. When children have been exposed to jigsaw in their early years, little more than a “booster shot” (one hour per day) of jigsaw in middle school and high school is required to maintain the benefits of cooperative learning. But what if jigsaw has not been used in elementary school? Admittedly, it is an uphill battle to introduce cooperative learning to 16-year olds who have never before experienced it. Old habits are not easy to break. But they can be broken, and it is never too late to begin. Experience has shown that although it generally takes a bit longer, most high school students participating in jigsaw for the first time display a remarkable ability to benefit from the cooperative structure.
Some teachers may feel that they have already tried a cooperative learning approach because they have occasionally placed their students in small groups, instructing them to cooperate. Yet cooperative learning requires more than seating students around a table and telling them to share, work together, and be nice to one another. Such loose, unstructured situations do not contain the crucial elements and safeguards that make the jigsaw and other structured cooperative strategies work so well.
