This book is very useful to create an adaptive e-Learning system by using student modeling and adaptive hypermedia. Adaptive e-Learning is an enhancement to make e-Learning system more effective by adapting the presentation of information and overall link structure to each individual user based on her/his knowledge and behavior. The adaptive e-Learning system provides better flexibility and capability than non-adaptive e-Learning system. It also leads the students to better learning results. Certainly, the adaptive e-Learning systems will benefit students' academic performance.
