Learning objects appeared approximately twenty years ago, opening an area of interdisciplinary investigation that has not yet arrived to a satisfactory theoretical formalization. Nevertheless, since then, numerous projects have been developed on the subject, that continues to catch the attention of different professionals and investigators.

The two areas of knowledge more directly related to learning objects are Education and Computer Science. The First one is in charge of the pedagogical aspects associated to the design and development of educative content based on the concept of learning objects, whereas the second one approaches the technological challenges related to the development of systems and educative platforms based on this concept.

This tutorial presents the foundations needed to understand the concept of learning object from a technological perspective. It presents general information on open technological standards that provide options and guidelines for the development of educative platforms that consist on different types of systems based on learning objects. Special emphasis is given to the SCORM standard. Tools and systems based on this standard will be used to author and package learning objects, and later to load them in web based runtime environments to visualize their content.
