2. 2 Introduction 1. A key factor in the development of hypermedia-based learning is cognitive style (CS) as it related to - users’ information processing habits / representing individual user’s typical modes of perceiving, thinking, remembering, problem solving. 2. The factors have significant effect on students’ CS in a hypermedia learning system : - non-linear learning (NL) - learner control (LC) - multiple tools (MT)

3. 3 Research 1. Exploring the correlation between the three learning dimensions. 2.Investigation the interaction among the three learning dimensions and their effect on students’ CS using two different methods of analysis. (generalized linear model and tree-based regression) 3.Comparing the effect of students’ background and the three learning dimensions on students’ CS.

4. 4 Literature framework 1. Hypermedia - networks of multimedia nodes connected by links are used to present information and manage retrieval. 2. Cognitive style - a deeper understanding. - awareness of students’ particular preferences. - enhance students’ learning, retention and retrieval of information.

14. 14 Conclusion 1.CS is a key factor in the development of hypermedia learning system since different types of learning dimensions are evident and must be taken into considerations in order to enrich the quality of education for students. 2. This can be applied to the design of adaptive hypermedia systems that can be tailored to individualize instruction.
