Jigsaw tasks have communicative goals, which means that they do not concentrate on grammar but on conveying meaning. This relates to the theory of interactionism, which says that students acquire a language better when communicating with others (not only with more experienced speakers of the target language but with fellow students as well). Although the focus is not on grammar the students need to use grammar in order to convey the information. Jigsaw tasks are supposed to imitate real speech events in which at least one of the partners has information the other one doesn't, so that he has to ask for it. An example of a jigsaw task would be the following:
There are two students, both get a picture, the two pictures are similar but not the same. For example both show a park, but one of them shows three children playing soccer in the park and the other one just two. There need to be several differences. You tell the students that they are supposed to find out what the differences are, without looking at the other picture but just talking. Furthermore you need to tell them how many differences they have to find. If they find them all or at least almost all, the students managed to communicate successfully and practised the language, which is the goal of the jigsaw task.
To me jigsaw tasks are the most efficient way to practice a second language for learners who have already acquired basic knowledge of the language. You can use it for beginners too, but then you have to set easier tasks, probably not using whole sentences but new pieces of vocabulary.
