ITEM FACTOR ANALYSIS OF THE MATHEMATICAL SELF-EFFICACY REVISED SCALE

This study was carried out to identify the major factors of the revised version of the Mathematical Self-Efficacy Scale-Revised (MSES-R). The sample consisted of 233 university students (125 females and 107 males) who have had a mathematical or statistics course. The results obtained from principal components analysis extracted four factors which have been consisted to the previous rescarch results and confirmed the constract validity of the scale. Also the Pearsonʹs correlation coefficient calculated between the MSES-R and the General Self-efficacy Scale was a39. The reliability coefficient (Alfa-Corenbach) obtained for whole scale as well as the subscales were satisfactory.
