Özet:

In this research, in order to adapt “Non-Linear Text Disorientation Assessment” tool which determines student's disorientation level in hypermedia environments and has developed by Beasley and Waugh (1995), first we got permission and then we do validity and reliability analysis. 301 students from different departments of Gazi Education Faculty are participated in this research. To provide content and understandability, the scale was examined by seven experts and English to Turkish translation convenience of scale by two experts in English. After obtaining the equivalence between original scale and Turkish draft form of scale, the experiment was carried out to the participants. The factor structure of scale was examined with EFA (Exploratory Factor Analysis). The variance of one factor was computed as %42.65. For reliability of the scale, Cronbach Alpha coefficient (.77) and Spearman Brown split-half correlation (.77) were computed. Lower and upper %27 groups' score difference were calculated with t-test (t=25.70, p=.000) Cronbach Alpha for random selection of subjects coefficient was .75 for the first half, and .79 for the second half This research will fulfill the need of a scale which is used to determine students' disorientation level in hypermedia environments which will be designed in Turkey.
