• Resumen

  • In order to fully understand the implications of object-oriented design patterns, students need to consider alternative designs to a problem and to analyse these solutions in terms of coupling, cohesion and extensibility. Lecture-based approaches to teaching design patterns do not provide students with the insights needed unless they already have experience in object-oriented design. In this paper we present an approach to teaching design patterns that promotes active learning and makes students participate in refactorings through role-play sessions. We describe two experiments that demonstrate student acceptance and present promising results on the effectiveness of the approach.
