This current study aimed to investigate the effectiveness of a training program based on De Bono Technique of the six thinking hats in developing the ability of producing the creative solution for the life problems through an independent training (of school curriculum). Regarding the sample, a cross-section of grade 10 female students was chosen from Muscat Governorate, Sultanate of Oman, 2012/2013. The Quasi- Experimental method was adopted by choosing two experimental and control groups. There were (32) girls in the experimental group and (32) girls in the control group. A pre-post tests "creative solution for life problems" was applied on the two groups. The. researcher used two equivalent form tests, forms (A and B) in order to study the effect of the training program on the dependent variable. The test validity was examined through judges evaluation. The two forms equivalence was used for the test reliability through applying one of the test formulas (form A) first and then after a while (form B) was applied. All reliability coefficients were very high for they ranged between (93.0 - 95.0). The results showed that there are statistically significant differences (05.0) in the students mean score in the two groups, the experimental and the control group in the post test regarding the total ability. While in the sub-abilities (authenticity, flexibility and fluency) for the creative solution for life problems, differences turned in favor of the experimental group with a big effect size. The results also showed that there are statistically significant differences (< 0.05) in the mean score of the experimental students group between the pre and post tests in the total ability. While in the sub-abilities (authenticity, flexibility and fluency) for the creative solution for life problems, differences were found favoring the post test with a big effect size. Hence, the results pinpointed the effect of the training program based on the artistic of the six thinking hats in improving students' abilities for the creative solution to solve life problems.
