S Student teachers' developmental characteristics and tendencies are important sources of personal differences in self-regulation processes and well being which affect behavioral reactions of students in and out of school settings. Thinking styles and goal orientations can be seen as two of those individual-differences. In the literature, each of these constructs and their relationships with academic achievement have been examined extensively. However, the relationships between the two constructs and the predictive power of them on academic achievement have not been investigated yet, except the study of Fan and Zhang (2009). On the other hand, researchers and educators need to understand and explain the quality of the students' performances by the nature of the relations of various theories addressing the learning behavior. It is also important for teacher educators to understand how their students learn and perform in order to find efficient ways for Bu araflt›rman›n amac›, ö¤retmen adaylar›nda düflünme stillerinin amaç yö-nelimleri ve her iki de¤iflkenin birlikte akademik baflar› üzerindeki yorday›-c› etkilerini incelemektir.

The participants were 270 undergraduate students studying in different departments of the Faculty of Education at Pamukkale University. Thinking Styles, Goal Orientations Inventories and Demographic Information Sheet were used to gather the data. The results of the correlational analysis show significant relationships among thinking styles, goal orientations and academic achievement. Regression analysis indicates that thinking styles predict goal orientations and goal orientations together with thinking styles predict academic achievement. In that sense, hierarchical and liberal Type I thinking styles a...
