This paper presents a framework for QoS enhancement of Adaptive Hypermedia Systems which is applicable to the area of education. The enhanced system adapts Web content based on both user-perceived QoS and user knowledge. The goal of the enhancement is to be able to improve performance metrics while not significantly affecting learning outcomes. A novel Perceived Performance Model that captures user-perceived performance and suggests content constraints to improve user satisfaction is described. The approach is tested by comparing the AHA! System to a QoS enhanced version of the same system. Preliminary results show that the enhancement significantly improves download times for users with low speed connections, while maintaining similar learning outcomes.
