8. The Car Pattern Design Pattern „ Each pattern describes a problem which occurs over and over again in our environment, and then describes the core of the solution to that problem, in such a way that you can use this solution a million times over, without ever doing it the same way twice“
10. Different solutions for the same problem Problem: How to get from A to B? Design Pattern = Solution to Problem in a context
11. Problem + Context –> Forces -> Solution “ It is based on the idea that every design problem begins with an effort to achieve fitness between two entities: the form in question and its context. The form is the solution to the problem; the context defines the problem.” (Alexander, 1964) A problem in different contexts raises different forces.
12. So...we know how to do it. Do we? ...these forms are bad solutions.
15. Pedagogical Patterns. E-Learning Patterns. Problem: How to organize asynchronous online collaboration? -> Patterns not only capture the form (=solution) but also appropriate situations (=context) for tools
