The next generation authoring adaptive hypermedia : using and evaluating the MOT3.0 and PEAL tools

Adaptive hypermedia allows for customization to the needs of the user. The authoring process however is not trivial, and is often the main hurdle to overcome in order to bring this useful paradigm to a greater number of users. In this paper, we discuss the major problems occurring in authoring of adaptive hypermedia, and propose a set of generic authoring imperatives, to be consulted by any system implementing creation tools for customization of content. Based on these imperatives, in this paper we extensively illustrate and discuss recent extensions and improvements we have implemented in the My Online Teacher (MOT) adaptation authoring tool set, including the MOT3.0 content authoring and labeling tool and the PEAL adaptation strategy author. Furthermore, we evaluate, compare and discuss two long term uses of the MOT tool set, first in 2008 and the second in 2009
