Informatics in Education

In this paper, we present a standard definition for learning objects, a controversy around it, and the resulted working definition, along with features to be held by learning objects, benefits of the object-oriented approach for learning, some pros and cons for using learning objects, and finally some quality standard guidelines for these objects. In addition, we introduce shortly a taxonomy of learning object types and the metadata standards that can be used for learning objects and the way they inter-relate. An overview of the content and capabilities of the instructional digital libraries available on the web is presented too. We conclude by pointing out some possible solutions for meaningful use of the learning objects that can be found on the web, either by construction of really useful community instructional digital libraries, or by using non-authoritative metadata to find these learning resources. Involving the conscious user in the process of making sense of the huge quantity of learning resources to be available on the web is, in our view, the only straightforward way to having fast access to the most appropriate (instructional) resource that is needed for a particular (educational) aim.
