We will develop below some reflections regarding how geometric data are introduced to the most frequently adopted DGS and how the constructive geometric processes (that are similar to the programs of "usual" computer languages) are stored. The later can be used as input for ADG processes.engconference paperhttps://www.cisuc.uc.pt/https://www.cisuc.uc.pt/open access514510.5GeometríaAlgoritmosQuestionnaireinterviewdynamic geometry systemGeoGebramathematics teachingmodellingInformática (Informática)Matemáticas (Matemáticas)Geometría1203.17 Informática12 Matemáticas1204 Geometría
