validity & reliability of the persian version of grasha-richmann student learning styles scale

introduction: the present study aimed to investigate the psychometric properties of grasha-riechmann student learning styles scale. method: the participants included 1039 students (421 students in human and 618 students in technical sciences), selected through the stratified sampling method from tehran university. they answered the grasha-riechmann student learning style scale and the data was analyzed with exploratory and confirmatory factor analyses. results: the findings acquired from exploratory factor analysis (n=561), using principal components analysis with varimax rotation showed that grasha- riechmann student learning styles scale includes six factors: avoidant, collaborative, participative, dependent, competitive, and independent. the factors acquired from confirmatory factor analysis (n=478), as model fit indices indicated, was confirmed by indices in exploratory factor analysis. the internal consistency of each subscale, ranging from 0.58 to 0.80, was at an acceptable level. conclusion: according to the findings, it seems that participative styles scale to be an instrument qualifying validity and reliability for measuring learning interactive styles.
