Reliability and Factor Structure of teachers’ goal orientation for teaching

The aim of this study was to investigate the factor structure and reliability of the teachers’ goal orientation Inventory.So 300 teachers from first to sixth grade were selected randomly by cluster sampling among primary school teachers in Tehran and answered to Butler goal orientation Inventory (2007). This research is descriptive and of type validation. Exploratory and confirmatory factor analysis were used to investigate factor structure of the instrument, and Cronbach’s alpha and Test-Retest method were employed for examining the reliability. The results of Principal component with Varimax rotation showed 4 factorial factorial solutions that explained and 51.33% of whole variance. he results of the confirmatory factor analysis showed good fit of the model. The Cronbach’s alpha of the instrument was 0.82 and the correlation coefficient of test-retest was 0.72 that showed acceptable reliability for the instrument. In general, the results show a good fit of Butler's goal orientation in the Iranian society and the reliability of this questionnaire that make it a suitable measure for determining teachers’ goal orientation for screening purposes.
