✦ Synopsis

In the last few years the (semi-) automatic sequencing of course material has become an important research issue, particularly the standardization of metadata for educational resources. Sequencing can help to generate hypermedia documents which, at their best match the learner's needs. To perform (semi-) automatic course sequencing, a knowledge library as well as modular resources can be used. Both must be described by metadata.

First, metadata standards (IEEE Learning Objects Metadata, Instructional Management Systems Global Learning Consortium, Dublin Core) are analyzed with regard to course sequencing. As an application example, Multibook, an adaptive hypermedia system used to teach multimedia technology, is described. Multibook uses metadata to create course se- quences semi-automatically. In this article we explain how a knowledge library can be used to create exercises automatically. We give an example of how courses can be sequenced in general by analyzing the creation of exercises. An evaluation of our system shows the advantages and drawbacks of the automatic course sequencing approach.
