Baig Pakistan Television (PTV), Lahore Centre, Pakistan ABSTRACT E-learning has become more learners centred because of adaptation. It is very difficult process to develop adaptive educational hypermedia systems because of complex nature of adaptation mechanism. There are several authoring tools through which it becomes very easy for everybody to develop such kind of systems. COFALE is also used for this purpose. It is an open source adaptive learning content management system. In this paper, we have assessed its quality through evaluating its object oriented design in terms of complexity, cohesion and coupling along with its usability in terms of adaptation features. Keywords: E-learning, adaptive hypermedia, complexity, cohesion, coupling, and usability. 1) INTRODUCTION E-learning has changed all the parameters of distance education. Learning in this mode was a dull and dry activity but now e-learning is fast, convenient, self paced and interactive (Hall, 2001). Martindale, Cates and Qian (2003) have classified educational websites in different categories including 1) instructional, 2) learning activities, 3) content collection, 4) links, 5) reference, 6) teacher resources, 7) vicarious participation, 8) interpersonal interaction, 9) virtual exhibits, 10) nonprofit organizations, 11) curriculum or research projects and 12) commercial. A lot of such kinds of online educational systems are running but still something is lacking that is personalisation or customization which means systems should adapt learners’ characteristics and guide them according to their preferences and educational background. In this regard, adaptive hypermedia can solve these problems through user modelling (De Bra, 1999). Adaptive educational hypermedia systems (AEHSs) are more dynamic and learners centred. These systems not only reduce the
