What, then, is the problem that design patterns solve, and in which contexts? As design patterns break new grounds in educational research and practice, challenging questions arise: how do we engage new audiences in the pattern paradigm? How do we adapt the form and modes of use of patterns to make them useful in diverse realms of practice? Why do we have such a strong conviction in the value of design patterns? The tradition of design patterns refers to concepts such as "timelessness" and "expertise". These are problematic in a world of accelerating change. Yet another fundamental principle is accentuated; the need to establish robust design languages capable of capturing the complexity of problems in our environment and offering verifiable solutions. I argue that design-level discourse is imperative in many critical domains of human activity, and that patterns should play a central role in such discourse. Over the last few years, my colleagues and I have been developing a methodology for participatory workshops for practical design patterns. This methodology has emerged from the "Learning Patterns" project, and is being refined by the "Pattern Language Network" project. In this talk, I will describe the methodology, its history and future plans, and provide some illustrative examples. I will also highlight some of the fundamental questions which is provokes.
