Assessing laptop use in higher education classrooms: The Laptop Effectiveness Scale (LES) - 4 views
-
Ashley Dixon on 02 Dec 12The purpose of this study was to develop and evaluate a scale used to assess in-class use of laptops in higher education. The Laptop Evaluation Scale consisted of four constructs: academic use, non-academic communication, playing games, and watching movies. All scale items showed acceptable internally reliability. A principal components factor analysis demonstrated good construct validity. Correlation among the LES constructs were significant but small enough to support the existence of four distinct constructs. All four LES constructs were correlated with average grade, time spent on non-academic activities, and perceptions of laptop helpfulness in class, thereby proving evidence for convergent validity. Finally, content validity was supported by frequencies of laptop behaviours reported as well as student comments. However, student comments indicate that the content of the LES may need to be expanded to include more specific academic and non-academic behaviours.
