Cooperative or collaborative learning methods generate more significant and lasting knowledge in students. That is why the Jigsaw technique has been utilized in courses related to object-oriented software development, as reinforcement for the lectures previously given on each subject. Although this technique was used, in previous experiences, to reinforce the theoretical concepts taught in class, it was defined as a future work to determine if sessions based only on cooperative learning methods can replace traditional lecture classes. This paper will present the design of a Jigsaw class to teach analysis class diagrams that replaced a traditional lecture class, and the results obtained in this experience. The paper will include the comparison of the results of the test that was taken after the Jigsaw class with the results of the test that it was taken after a traditional lecture class in a previous semester. The grades obtained by the students when it was applied a test after the Jigsaw class are better than the grades obtained by the students who participated in a traditional lecture class.
