Objective: The present research aims to study the factor structure, reliability, and validity of the Successful Intelligence Scale. Method: Using the multi-stage cluster sampling method, 500 (including 175 female and 325 male) subjects were selected from among public school students in Karaj. Results: The exploratory factor analysis was performed using the principal component method. The results confirmed three factors of successful intelligence (i.e. analytical, creative, and practical intelligence) as well as the principal factor. Reliability of the scale items was examined using Cronbach’s alpha coefficient, and its validity was investigated using factor analysis. Internal consistency of the questionnaire was acceptable, and the Cronbach’s alpha for the subscales was between 0.74 and 0.81. Also, the confirmatory factor analysis results confirmed that the structure of the scale had an acceptable fit to the data, and that the goodness-of-fit index for the model was observed. Conclusion: The results of confirmatory factor analysis were almost close to that of studies done in the original cultural context. Validity and reliability of the scale were also close to that of previous researches. Considering the desirable psychometric property, therefore, this scale is an appropriate instrument for measuring the students’ successful intelligence.

The purpose of this research was to combine the quantitative results of the researches related to the students' math performance. For this purpose, all studies which have been done in Iran from the year 1381 to 1388, were collected, using the quarterly and scientific-research articles. In general, 40 cases of them, had meta-analysis measuring features, in particular the effect size measuring feature. The Hodges’s method has been used for metaanalysis and the Cohen’s method has been used for interpreting the findings. The results indicated that there is a significant relationship between math performance and selfe-fficacy, self-regulation, motivation, goal orientation, learning strategies, teaching methods, cognitive styles, reading styles, gender, and perception of the class structure. Among the mentioned variables, self-efficacy was found to be the best predictor of students’ math performance due to its high level of variance.
