Development of Self Efficacy and Attitude Toward Analytic Geometry Scale (SAAG-S)

摘要

The aim of this research is to develop the Analytic Geometry Perception and Attitudes Scale and to examine its validity and reliability analyses. The sample of study consists of 236 university students from Sakarya University. In this study construct and concurrent validities, internal consistency, test-retest reliabilities and item analysis of the scale were examined. As a result of factor analysis for construct validity three factors have emerged which named “attitude toward analytic geometry”, “self efficacy of analytic geometry” and “requirement for achievement”, consist of 26 items and account for the 44.4% of the total variance. The internal consistency reliability coefficients were .79 for attitude toward analytic geometry, .81 for self efficacy of analytic geometry and .77 for requirement for achievement. Findings also demonstrated that item-total correlations ranged from .35 to .75. Test-retest reliability coefficient was found .85 for scale. According to these findings the Analytic Geometry Perception and Attitudes Scale can be named as a valid and reliable instrument that could be used in the field of education.
