In this article some considerations are introduced on the method of the Problem Based Learning (PBL) for Nursing education. The method is criticized in its application. From the idea that it can be an active method, not conservative and that can be useful to develop the critical thinking, if it is not correctly used, it can result instead in a method that confines the education, negatively standardizes it and limits the critical thought. Some reflection points are underlined to promote a debate on the topic.
