Abstract
Today, multimedia capabilities of computers offer teachers vast possibilities for improving their teaching techniques. However, these tools have also created new problems, which are particularly visible in the context of a technology monoculture. Education is, therefore, facing the great challenge of changing the superficial, algorithm-like use of computers to find efficient solutions to those problems, a process that must be framed within metacognition principles and Freire’s concept of freeing pedagogy. Free software represents a paradigm shift in this context and, at the same time, its use can contribute to solve the most common technologyrelated issues that educators must cope with in their everyday teaching.
