El nou marc d'avaluació de la competència científica PISA 2015 : revisió i reflexions didàctiques

After some recent years in which the well-known competence-based teaching has been omnipresent in most educational systems, the new framework for assessing scientific liter-acy in PISA 2015 presents in a much more operational and practical way the education for the achievement of scientific literacy. This new approach gives an answer to the lack of a sufficiently clear definition on how this competence-based education should be conducted, something that has been too ambiguous until now. In this paper, we review the main changes and features of this new framework and reflect on the possible implications when implemented. On the one hand, the new framework slightly modifies the three key scien-tific competencies. On the other hand, it clarifies that to achieve these competencies and become a scientifically literate person it is necessary to have a body of knowledge: con-tent, procedural and epistemic knowledge. How these different types of knowledge are de-fined and how they can be integrated in order to achieve each of the scientific competencies is the most important contribution of this new PISA framework 2015.
