New technologies, in particular dynamic geometrical software, have been introduced in the teaching and learning of mathematics at secondary school in recent years in Vietnam. However, the institution of secondary education does not yet seem to be favourable to this introduction. In this paper, after describing the main characteristics of technological context and geometrical curriculum in secondary school in Vietnam, we analyse some examples of teacher use of dynamic geometry software in class activities. This analysis permits us to characterize different knowledge types as well as didactic functionalities of this software in teaching practice. Finally, we focus on a case study in order to bring out some elements of the genesis of technological professional use by one teacher.
