Personalized E-Learning is a research area with the grandiose goal of automatically or semi-automatically matching the learning contents with the needs and preferences of the learners. This paper proposes a modest goal of creating learning contents to help the learners engaged in self-paced E-Learning learn effectively at appropriate levels of difficulty and detail. It also proposes a goal of making it easier for the content creators to create new learning contents by reusing and adapting existing content fragments. More ambitious goals may be addressed by building on the results of these modest goals.
