This research aims to investigate the effect of collaborative learning on the self-confidence insolving mathematical problems. The statistical population consists of all female students of thedistrict one of Bandar Abbas in year 2014-2015. The sample includes 52 students (26 students incontrol group and 26 ones in test group). The Questionnaire of Self-confidence in SolvingMathematical Problems was applied as the data collection instrument. Quasi-experimental methodwas applied. Therefore, control and test groups were gathered before intervention of selfconfidence-related data. Then, the control group was exposed to traditional method and the testgroup experienced the intervention of collaborative learning. After the intervention, when theclasses were finished, post-intervention date were collected. The data collected in pre-test and postteststages was statistically analyzed through ANCOVA. Finally, results indicated that collaborativelearning has a significant effect on the self-confidence (p=0.001), ability (p=0.001), interest (p=0.001),and persistence (p=0.001) in problem solving, while it has no significant effect on inability to solveproblems (p=0.054). Therefore, collaborative learning is a suitable method to improve selfconfidencein solving mathematical problems among the students.
