structural equation modeling on Test Anxiety and Locus of Control on Academic Achievement by Achievement Motivation as a mediator

 Academic progress is one of the main priorities of schools, which is the main goal of education.   This study investigated Achievement Motivation as a mediator of the relationship between Test Anxiety and Locus of Control with Academic Achievement between Test Anxiety and Locus of Control. Correlation studies based on structural equation modeling technique, in particular regression equations (combining path analysis and factor analysis second). A total of 508 students (255 boys and 253 girls) were selected by simple random sampling. Hermans achievement motivation inventory, Test Anxiety Questionnaire and Rotter·s Locus of Control Scale were used to collect data. GPA was as academic achievement.   The results showed that the research model was confirmed and in general, 27% of academic achievement can be explained by achievement motivation, test anxiety and locus of control. So with decrease of Test Anxiety and increase locus of control can increase achievement motivation in students and improve academic achievement.
