ISIS-Tutor: adaptive annotation/hiding
Tutor for CDS/ISIS library system
- CDS/ISIS is a library system for PCs sponsored by UNESCO
- ISIS Tutor developed by Peter Brusilovsky and Leonid Pesin
- descendent from an older system ITEM/P (Moscow State Univ.)
- domain- and student model for monitoring student knowledge
- tutor component to perform adaptive task sequencing
- hypertext component lets students navigate through course material.
- learning environment lets users interact with ISIS
- versions with adaptive link annotation and link removal
- evaluated to determine learning effect of using adaptation

Notes:
ISIS-Tutor is an intelligent tutor for the CDS/ISIS library system that was developed by UNESCO.
The ISIS-Tutor was developed at the International Centre for Scientific and Technical Information (ICSTI) and Moscow State University, by Peter Brusilovsky and Leonid Pesin.
The interrelated domain model and student model form the heart of the system. It makes the system integrated and adaptive. Modules of ISIS-Tutor use the student model to adapt their work and update it to reflect the student's progress.
The tutor component supports adaptive task sequencing, which means that knowledge demonstrated by the student in the past is analyzed and the system selects an optimal teaching operation to perform. The component deals with three kinds of teaching operations: concept presentations, examples and problems. Using the Student Model and the available tasks the tutor can select an optimal teaching operation for the given student in each stage of the learning process.
The hypertext component supports student-driven acquisition of conceptual knowledge. It is an integrated part of the system. It means that the component uses the student model to provide adaptive navigation support for the given student, and it updates the student model to reflect the results of the student's work with the component.
The learning environment allows the user to play and experiment with print formatting commands. It provides step-by-step execution and extended visualization. Student work in this component is also reflected in the student model.
Three different version of ISIS Tutor were tried in evaluation experiments: one without adaptive navigation support, one with adaptive link annotation and one with annotation and the removal of inappropriate links. We show the versions and the evaluation on separate viewgraphs.
