A Psychometric study of the student’s attitudes towards mobile learning scale among medical students in Iran University of Medical Sciences
Abstract
BACKGROUND AND OBJECTIVE: One of the important challenges in education in recent years will be the adoption of mobile devices in the learning sphere. This study aimed to psychometric of the attitudes towards mobile learning scale. METHODS: This study was psychometric of 120 subjects was recruited from the medical schools in Iran university of medical sciences. Initial instrument was adopted from previous studies compromised 21 –items, likert type. Instrument validation procedures included impact item score, content validity index (CVI) and content validity ratio (CVR) was done with the judgment of 10 experts and 20 items was remained in instrument in this phase. For the construct validity exploratory factor analysis was used. Internal reliability of the scale was determined by alpha cronbach coefficient and with the test-retest method the external consistency of a test was assessed. FINDINGS: Of the original 21 items, all of them about the impact item index over 1.5, CVR over 0.62, and CVI over 0.7 were considered as valid; based on exploratory factors analysis, 21 items remained in scale. Considering a minimum eigenvalue of 1 for each factor, the four factors were labeled as: mobile learning usage, mobile learning restriction; Freedom in the use of mobile phones in learning and capability of mobile learning. This instrument capable of predicting 68.516% of the properties as an attitude toward learning with mobile learning variance. CONCLUSION: The results of this study indicated the strength of the factor structure and reliability of an instrument for measuring student attitudes toward learning with mobile learning. The results of study can assess student attitude towards mobile learning in universities and other educational institutes.
