**3. Collaborative production model of educational resources for HCI**

This section proposes an extension of spiral model from Boehm software process model [10] to describe a collaborative production of HCI educational resources (see model of **Figure 2**). This model is characterized as an iterative, incremental, and interactive process. Then, in the early stage of planning phase, it is necessary to define a plan for the production of new HCI educational resources as well as the organization of human resources. It is involving here system analysts, media specialists and content producers are involved here. The next phase (design phase)

focuses on the validation of new educational resources at the design level before launching a massive development of these resources. The construct phase is for the development of educational resources using collaborative environment; the process is directly influenced by learning and social networks, involving practice communities and collaborative tools. The fourth phase is for the evaluation of HCI educational resources using repositories to allow the content that is retrieved, recommended, appointed, grouped, and so on to be a contender to the future versions of the course.

Of note the collaborative applications, services, and online repositories are located in the center of the proposed model in **Figure 1**; at least one of these key elements is necessarily used by the participants in every phase of the development of educational resources. In fact, a multidisciplinary team is required to implement the previous model, including teachers, reviewers, researchers, content organizer, and content producer. They are involved in a huge effort of creating resources that are designed for use in formal and non-formal educational situations. The whole responsibility lies with the multidisciplinary team to provide creative content and give certain guarantee that it is the most suitable content that could be offered to each specific learning/teaching situation [5].

The next two subsequent sections implement the previous model in two real case studies where teachers and researchers from several universities cooperate in order to produce educational resources in Spanish language to the HCI community of Latin America.
