Validity & reliability of the Persian version of Grasha-Richmann student learning styles scale

Introduction: the present study aimed to investigate the psychometricproperties of grasha-riechmann student learning styles scale.method: the participants included 1039 students (421 students in human and618 students in technical sciences), selected through the stratified samplingmethod from tehran university. they answered the grasha-riechmannstudent learning style scale and the data was analyzed with exploratory andconfirmatory factor analyses.results: the findings acquired from exploratory factor analysis (n=561), usingprincipal components analysis with varimax rotation showed that grasha-riechmann student learning styles scale includes six factors: avoidant,collaborative, participative, dependent, competitive, and independent. thefactors acquired from confirmatory factor analysis (n=478), as model fitindices indicated, was confirmed by indices in exploratory factor analysis. theinternal consistency of each subscale, ranging from 0.58 to 0.80, was at anacceptable level.conclusion: according to the findings, it seems that participative styles scaleto be an instrument qualifying validity and reliability for measuring learninginteractive styles.
