Patrones de diseño: ejemplo de aplicación en los Generative Learning Object

This paper describes what a design pattern, its objectives and classifications with examples of each of them. The work also provides information on some projects that design patterns applied to learning objects (LO) is currently performed as well as entrepreneurship by business and by public bodies and universities in developing the object repositories reusable as teaching support, teaching mainly virtual, ie in support of e-learning. Following this line, it looks at the Center of Excellence (CETL), their characteristics and scope of their actions in this field such as design, development and use by members of the Universities (London Metropolitan, Cambridge and Nottingham) Reusable Learning Object (RLO) or generative learning object (GLO). Finally, it proposes an example of design pattern applied to the latter issue, the Center of Excellence, as is the generation of GLO from a RLO. This work is structured in three main blocks are: · Introduction to design patterns, historical introduction, objectives and examples · Projects on learning object repositories existing · The CETL Project. · The proposed design pattern.
