“…Most studies assert that the strongest predictor of mathematics achievement is mastery experiences, followed by social persuasions, physiological states, and the weakest predictor is vicarious experiences [12], [19]- [21]. On the other hand, there are some studies that argue social persuasion has greater association with mathematics achievement than the three [17], [22], [23]; mathematics performance and vicarious experiences have no relationship [17], [22]; and the relationships of psychological states with academic achievement and mathematics achievement vary i.e. while some studies show that physiological states are significant factors of achievement [16], [17], [24], [25], others assert that it has low and insignificant effect [19], [24], [26]- [28].…”
