Abstract
Several hypermedia learning environments have been developed in the last years, with the objective of
helping students to acquire specific concepts in a given domain, as well as problem-solving abilities. However,
there are still many different and sometimes conflicting claims about learning effectiveness using such
environments. We present an empirical evaluation of a learning hypermedia with a tutorial component that
exploits Artificial Intelligence techniques. This hypermedia, called Logiocando, has been designed for use by a
special category of user, namely children of the fourth level of primary school (9-10 years old), to help them to
learn basic concepts of logic. This category of user demands special attention to usability of the hypermedia. For
this reason, design and development of the hypermedia have been carried out following a learner-centred
methodology, in order to build a system that satisfies clear usability objectives. The aim of the study herein
reported was to evaluate the learning effectiveness of Logiocando and to estimate the difference between two
approaches: computer-based using a hypermedia system, and traditional, namely a typical lesson in the
classroom. The results have shown that the hypermedia can be considered a valid support in the process of
learning and deepening a topic.
