Today there is much insistence on the need to learn to learn, to learn to understand and to learn to undertake, but what is most important, difficult and a condition for all of the above, is to learn to unlearn. There is much talk of educational innovation, of the need to change, but most changes are limited to introducing new technologies, changing the furniture or incorporating the discourse of the need for new management or strategic planning. Real educational change requires breaking with comfortable practices, routines, rituals, habits, customs. It means, in a word, unlearning the culture entrenched in old educational practices, which prevents us from innovating, creating, inventing the new school and the education we need today.
