Adaptivity in ProPer

Adaptive Educational Hypermedia Systems provide personalized educational content to learners. However most of them do not support the functionality of Learning Management Systems (LMS) and the reusability of their courses is hard work. On the other hand some LMS support SCORM specifications but do not provide adaptive features. This article presents ProPer, a LMS that conforms to SCORM specifications and provides adaptive hypermedia courses. ProPer manages and delivers SCORM compliant courses and personalizes them according to learner’s knowledge, goals and personal characteristics. In addition learner’s progress and behavior is monitored and useful feedback is returned to tutors. ProPer will be used for an adaptive Java Programming course distribution to CS1 students. Statistical feedback will be gathered by tutors in order to improve course effectiveness. The technology background is briefly given and the system’s architecture and functionality are analyzed.

MetaSockets: design and operation of runtime reconfigurable communication services

AbstractThis paper describes the internal architecture and operation of an adaptable communication component called the MetaSocket. MetaSockets are created using Adaptive Java, a reflective extension to Java that enables a component's internal architecture and behavior to be adapted at runtime in response to external stimuli. This paper describes how adaptive behavior is implemented in MetaSockets, as well as how MetaSockets interact with other adaptive components, such as decision makers and event mediators. Results of experiments on a mobile computing testbed demonstrate how MetaSockets respond to dynamic wireless channel conditions in order to improve the quality of interactive audio streams delivered to iPAQ handheld computers.
