Computers and education in the 21st century

ConieD is the biannual Congress on Computers in Education, organised by the Spanish Association for the Development of Computers in Education (ADIE). The last Congress, held in Puertollano (Ciudad Real), brought together researchers in different areas, ranging from web applications, educational environments, or Human-Computer Interaction to Artificial Intelligence in Education. The common leitmotiv of the major part of the lectures was the World Wide Web. In particular, the focus was on the real possibilities that this media presents in order to make the access of students to educational resources possible anywhere and anytime. This fact was highlighted in the Conclusions of the Congress following this Preface as the Introduction. From the full 92 papers presented to the Programme Committee we have selected the best 24 papers that we are presenting in this book. The selection of papers was a very difficult process, taking into account that the papers presented in the Congress (60) were all good enough to appear in this book. Only the restrictions of the extension of this book have limited the number of papers to 24. These papers represent the current high-quality contributions of Spanish research groups in Computers in Education.
