[ABSTRACT] This study reviews the development processes of Jigsaw strategies, and aims to investigate the variety of Jigsaw methods and compare their characteristics. Previous studies confirmed that the Jigsaw technique is an effective cooperative learning technique that promotes positive attitudes and interest in students for developing inter-personal skills. Meanwhile, it has significantly increased students' academic achievements compared to traditional methods. Analyzed papers related to the Jigsaw method were collected, and then the similarities and differences in the development process were summarized, while elucidating the significance of the improvements. From this process, it is found that the Jigsaw technique has some limitations. Therefore, this review will put forward some suggestions about how to improve this technique.
