MetaLinks, an authoring tool and web server for adaptive hyperbooks, is described. MetaLinks hyperbooks provide textbook-like content in a flexible manner that supports opportunistic processes of active reading and learning. Through adaptive methods a single on-line artifact can address the diverse needs of a variety of user goals and backgrounds. The(More)
While intelligent tutoring systems (ITSs), also called knowledge based tutors, are becoming more common and proving to be increasingly effective, each one must still be built from scratch at a significant cost. We have developed domain independent tools for authoring all aspects of a knowledge based tutor: the domain model, the teaching strategies, the(More)
We describe Wayang Outpost, a web-based ITS for the Math section of the Scholastic Aptitude Test (SAT). It has several distinctive features: help with multimedia animations and sound, problems embedded in narrative and fantasy contexts, alternative teaching strategies for students of different mental rotation abilities and memory retrieval speeds. Our work(More)
We describe a portable coaching environment used within a domain-independent inquiry-learning infrastructure. This coach reasons about a student’s knowledge and offers pertinent, domain-specific feedback. It promotes good inquiry behavior by critiquing the student’s hypotheses and supporting data and relationships among propositions. Four inquiry tutors in(More)
Interest in neural networks has expanded rapidly in recent years. Selecting the best structure for a given task, however, remains a critical issue in neural-network design. Although the performance of a network clearly depends on its structure, the procedure for selecting the optimal structure has not been thoroughly investigated, it is well known that the(More)
We described a formative evaluation of Tectonica Interactive, an introductory geology hyper-book that was authored and delivered using the MetaLinks software. MetaLinks is a framework and authoring tool for the creation of adaptive hypermedia documents that support the learner's exploration of richly interconnected material. The formative evaluation(More)
We have developed a range of critical thinking environments for science education that span several academic content areas, including human biology, geology and forestry. All environments share a methodology, infrastructure and sets of assumptions and tools, which allows them to leverage from the accomplishments and intuitions of the others. These tutors(More)
We describe Wayang Outpost, a web-based ITS for the Math section of the Scholastic Aptitude Test (SAT). Wayang Outpost has several distinctive features: a large breadth of problems with multimedia animations and sound in the help, problems embedded in narrative and fantasy contexts, alternative teaching strategies for students of different mental rotation(More)
