The study aimed at identifying the effectiveness of the educational platform WinjiGo on improving the achievement and creative thinking of grade 10 female students in the subject of Social Studies. To achieve this aim, the researcher uploaded the content of the target unit and all its accompanied activities to Winjigo platform. She also developed an achievement test, creative thinking test and a three domain scale to measure students' attitudes towards WinjiGo platform. The validity of the instruments was checked by experts. The reliability was checked by Alpha Cronbach. The researcher used a quasi-experimental design. The sample consisted of 62 grade 10 female students from Um Saad Al Ansariya School (7-10). The sample was divided into two groups: the experimental group, which consisted of 31 students taught by WinjiGo platform, and the control group, which consisted of 31 students taught by the traditional method. The equivalence between the two groups was checked by implementing achievement and creative thinking pretests. The results revealed statistically significant differences (a= 0.05) between the means of the two samples in the achievement and creative thinking tests for the benefit of the experimental group. The results also indicated that students have high positive attitudes towards using the WinjiGo platform in studying Social Studies. Thus, based on the results of this study teachers should be encouraged to utilize this platform to improve students' achievement and creative thinking.
