In this article the visualization tool "Didactic Process Map" (DPM) is presented to discuss learning processes and visualize the solution part of pedagogical patterns. Such an instrument has to be easy to learn, easy to use and must be able to visualize the essential aspects of learning settings. Completeness and formal validity are not required because DPM is supposed to be used by humans discussing with each other (human interaction) and does not need to be processable by computers. The target audience of DPM are learners, teachers and practitioners, therefore it is important to keep the amount of map-elements as low as possible.
In order to keep DPM simple and easy usable an approach following the 80:20-principle (pareto-principle) has been chosen: Essential properties of learning processes must be visualizable while unessential and rare used properties have to be left out. They can be communicated literally and negotiated orally. With this principle in mind, the DPM-approach distinguishes itself from existing efforts for an exhaustive learning process description language and fits well into the design pattern approach.
