AHA! the next generation

AHA! is a simple Web-based adaptation engine that was originally developed to support an on-line course. This paper describes AHA! version 2.0, a new major release that aims to significantly increase the adaptive versatility of AHA! without sacrificing AHA!'s simplicity that makes it easy to use. The new features in AHA! are inspired by AHAM [4], a Dexter [6] based reference model for adaptive hypermedia systems.
