The author presents results of research on informatics education with emphasis on informatics system comprehension for twenty-first century local, national and global needs. Learners have to create a sustainable cognitive model of a computer to demystify such an informatics system. This can be achieved by fostering system comprehension. The underlying hypothesis of this article is that knowing networked fundamental ideas of informatics and their combination in a system helps learners to develop a cognitive approach to informatics systems. In particular it focuses on the development of networked thinking as a cognitive precondition for mental models of systems. The work contributes to the discussion on what kind of comprehension is required and how far system comprehension can be supported. Assuming there are two pillars of the subject of informatics, i.e., informatics modelling and comprehension of informatics systems, object-oriented design patterns join both together. Knowing about multifaceted interdependencies between the components of a system and the cognitive analysis of such a system is of great value in overcoming the tendency to search for a single cause of an effect. With this in mind, the author offers a theoretical basis as to why design patterns are an essential component of informatics as a subject at secondary level. New media require a new cognitive approach. With regard to the didactic system developed by Brinda and Schubert, exploration modules are an appropriate way to support teaching and learning of design patterns in practice. This article describes a current project developing an exploration module to introduce design patterns with an emphasis on system comprehension to learners at upper secondary level.
