Hypermedia systems give freedom of navigation to the users but majority of them give same view to all of them. In this regard, adaptive hypermedia provides solution to this problem through personalisation. E-learning can also be made effective by adapting the needs and background of learners. PAHMS (pedagogical adaptive hypermedia based educational system for mathematics at secondary level) provides adaptive presentation of content and adaptive navigation by adapting the preferences and educational background of learners. It also provides the facility of adaptive peer’s searching. In this way, it reduces the cognitive overload of learners and prevent them being lost in hyperspace of the system. This thesis describes the development of PAHMS. This system provides pedagogy of mathematics following curriculum designed by Ministry of Education, Pakistan to both in-service and student teachers. Pedagogy comprises of application of famous teaching methods in different branches of mathematics with examples. It also describes complete procedures along with merits and demerits of these methods. E-learning objects including instructional, collaborative and assessment objects for the pedagogy have been developed as well. Effectiveness of PAHMS has been ascertained through survey research conducted from the teachers of mathematics at secondary level. Majority of them gave positive response about the system.
