This article addresses three types of learner support: (a) support for optimizing use of a computer program, (b) support for learning content, and (c) support for monitoring and enhancing learning. It proposes a multidimensional model of learner-support space defined by the intrusiveness of the delivery methods employed and the prescriptiveness of the content of the learner support provided. Methods of delivering such support through various interface elements, as well as several scenario-based examples of learner support matching the designer's philosophical beliefs, are discussed. The article closes by identifying relevant research questions for future study.
