Abstract

Object of this study is, to determine effect of adaptability of study media and level of adaptability on satisfaction and cognitive loads of students. The experimental period of the research is applied to 120 university students from the 1st and 4th year of their education at 2011-2012 semester. The students studying their 1st year have been chosen from the ones excluding the engineering field and the students studying their 4th year have been chosen among the engineering departments. Three different models have been developed as non-adaptive, adaptive-presentation and adaptive-navigation. For the measurement of satisfaction, the scale has been modified by the researcher. For cognitive load, the scale has been used that is developed by Paas (1992). Since the satisfaction related scales are applied at the end of the experimental period solely as a final test; in order to test whether there exists a difference among the groups, one-sided variance analysis (ANOVA) has been applied. To identify whether there is a significant difference of the observations among the groups’ cognitive load scores arithmetic averages’ ANOVA test has been applied on the single factor for the Repeated Measures (Repeated Measures ANOVA). According to the ANOVA findings, the satisfaction levels of the students where there is a adaptive navigation is relatively higher compared to the others. The cognitive loads of the students where there is no adaptation is relatively high compared to the others. The difference between the cognitive loads of students for adaptive presentation and adaptive navigation has not been assessed significant. In order to examine the scales’ structural validity basic components (factor) analysis technique is used, and to determine the reliabilities internal coherence coefficients (Cronbach Alpha) have been calculated. For the test of entire attempts .05 significance level has been considered as basis.
