SIIE is an international forum of Spanishspeaking, Portuguesespeaking and Englishspeaking researchers devoted to investigate and implement the use of computers in education. In 1999 the Symposium was held in Aveiro, Portugal. In the year 2000 it was celebrated in Puertollano, Spain. Other meetings preceded this Symposium, namely, the 'Simpsio de Investigao e Desenvolvimento de Software Educativo' held in Lisbon, Coimbra and Evora, two Congresses held in Spain and organised by ADIE: Encuentro de Informtica Educativa, in Madrid and the so successful ConieD'99 held in Puertollano in 1999. A collection of Conied'99 papers is also published in this collection with the title 'Computers in Education in the 21st Century' (2000).
