This LABCALC project organized on November 6-7, 1997, the meeting "Encontro: A Informatica no Ensino da Matematica", which had the participation of more than sixty teachers and researchers from the various Brazilian universities. We have collected at this occasion interesting site addresses from people developing similar work that you can access below.
