Evaluación del aprendizaje: ¿problema o herramienta?

Traditionally evaluation has been seen as the last step in pedagogical processes, a sort of final requirement. This has been changing in the last decades because evaluation has become the object of experimentation and research in education. As a result evaluation has turned into a powerful tool in the improvement of both teaching and learning. And specifically for students it is now another way to learn. This article, a literature review, gives an overview of the knowledge coming from research in evaluation in education and of the new forms of evaluation that are now being used, which have made evaluation a powerful pedagogical tool.
