The present study was carried out to investigate the effect of learning by jigsaw 2 methods on educational achievement. This quasi-experimental research included pre-test and post-test with control group. The research population was comprised of all high school boys and girls studying in Bandar Abbas. The research sample contained 30 high school first-grade girls and 30 high school first-grade boys in experimental groups and the same number in control groups. In the experimental groups, jigsaw cooperative method was used for a course of 8 sessions, while the control groups received traditional method. Data were analyzed with ANOVA. The results revealed that training by jigsaw 2 method caused increased educational achievement in experimental groups, which was significant at error level of p<10.001. In addition, teaching through jigsaw 2 resulted in increased educational achievement in the boys experimental group, which was significant at error level of p<0.01. The same applied to girls experimental group at error level of p<0.01. Therefore, jigsaw 2 technique was more efficient than traditional method in teaching mathematics. Additionally, those who were trained by jigsaw 2 showed greater educational achievements.
