This study aims to explore processes associated with the design of educational activities for learning of mathematics involving computer software. In particular, it consides the processes involved in the design of microworlds, both in respect to the incorporation of mathematical objects in the environment and the interactions of the mathematics teachers who participated in the research. Within a constructionist perspective, it investigated the conjecture that the iterative design of a microworld can involve designers in constructing new relationships with the computer, with mathematics and with its teaching. A design-based research methodology was chosen for the study, with two phases of experimentation developed: The individual design phase involved the construction of a microworld for geometrical transformations; in the collaborative design phase, a group of six mathematics teachers from a public sector school in the interior of the state of São Paulo participated in the iterative design and e design of two microworlds during a set of twelve research sessions. Analysis of the cycle description-execution-reflection-debugging, that characterized the interaction during both research phases, indicated that participating in the process of computational transposition, by which a mathematical object becomes incorporated in a microworld, enabled both the researcher and the teachers to construct new meanings situated abstractions as well as to adopt new perspectives on the design of learning activities. The opportunity to act simultaneously as designers and as learners also permitted a change in the attitudes of the teachers, increasing their sense of security in relation to the computer.
