Abstract
This article deals with a research work related to the use of technology for Mathematics teaching and learning. In this one, some current educative aspects and tendencies converge, such as: the use of software, the use of several internet platforms, educative software design and development, and the use of calculators and computers. We study the mentioned tendencies from the point of view of teachers (with educational perspectives) and also from the point of view of the learning of mathematics (cognitive issues), through the creation and use of Interactive Technological Environments for the Learning of Mathematics (ATIAM). Also, we include research results linked with design and construction of software for the learning of mathematics in ATIAM´s environments.
