Abstract:
This paper presents an adaptive tool for self-assessments. The proposed system supports the selection of
assessment items from an item bank based on a number of criteria such as the topic, the difficulty level of
the items and a lightweight learner profile. For interoperability reasons, the assessment items are encoded
using the IMS QTI standard and the topics are represented in Topic Maps XML. Items are included in the
Topic Map as occurrences in one or more subtopics. The items are retrieved using parameterized XQuery
scripts and they are adaptively presented to the user based on their knowledge level. Furthermore, some
visual clues are associated to the items in the test that participants should attempt. The evaluation
experiments showed that the tool supports more effectively self-assessment and motivates users to be more
actively engaged.
