College Trichy, Tamilnadu, India Abstract With bandwidth increasing at a constant pace, technology in education has become an important part for delivery of educational content to students. Online learning in various forms is gaining popularity but lacks the adaptability required to hold the learners attention due to its rigid structure. Though animation and powerful graphics enhance the learning content, delivery of content according to learners need is yet to become a reality. It is not possible to build a l earning system that can satisfy every learner as some people respond best when they see basic facts on a clean page, others when they have a lot of charts and graphs at their fingertips. To overcome these shortcomings the content delivery itself can be made dynamic based on the learner's need. In this paper we propose a novel method to identify a user's need based on the cognitive behavior of the user. Based on t he response of the user, an decision tree induction algorithm is used to predict the requirements of future users. Keywords: User interface design, Cognitive approach, online learning, and decision tree induction. 1. Introduction Web based learning encompasses all tools that make use of the internet for delivery of learning content. The learning content can be in the form of tutorials, online discussion group or virtual platform for hands on training[1]. However the distinction on the types is blurred and overlaps each other. Web based learning tries to eliminate face to face lectures and is enhanced using multimedia followed by self assessment tools[2]. Online discussion groups involve a group of students facilitated by a teacher online who may involve in didactic teaching [3]. Web learning represents the evolution of computer assisted instruction for the delivery of content over the internet. Web based learning include hyperlink functions that permit cross referencing to other resources and searching capabilities which are crucial for the principles of constructivism based learning[4] theory which emphasizes that learners create their own knowledge base over a period of time. However the disadvantages faced in computer assisted instruction translates to web based learning and hence significant improvements may not be obtained if the content and user interface is not proper. Advantages of web based learning include the overcoming of physical distance which is a cardinal feature separating web based learning form other computer assisted teaching methods[5]. Web based learning facilitates the teaching of students scattered globally which also permits the possibility of economies of scale. The major disadvantages of web based learning include social isolation, de individualized instruction, poor instructional design and technical problems [6]. Cognitive theory of learning suggest that learning is based on mental processes [7,8.9] while behavioral learning method suggests that learning results from pleasant or unpleasant experiences in life. Since epistemological processes are related to cognitive theory, the learning process comes out of experience, perception, memory and overtly verbal thinking[10,11].
