Aim/Purpose: In this paper, we highlight the need to monitor and diagnose adaptive e-learning systems requirements at runtime to develop a better understanding of their behavior during learning activities and improve their design. Our focus is to reveal which learning requirements the adaptive system is satisfying while still evolving and to…

The report is a review of research results which concern sequencing (procedures for validating the hypothesized ordering of the subordinate tasks in a learning hierarchy) and practical applications of learning hierarchies in instructional design. Indirect versus direct validation procedures are examined in detail. (Author)

The sequences of learning sets (intersequence) and instructional events (intrasequence) were empirically validated for a hierarchy of concept and rule using skills. Experiments with high school students showed no differences between empirical and reordered inter- or intrasequence on time to mastery; nor was there a difference in the number of…
