Pedagogical Patterns: their Place in the Genre Sally Fincher & Ian Utting ITiCSE 2002 Aarhus, Denmark 24-26 June 2002
What are patterns? • A way of capturing good design practice • A way of developing a common design vocabulary • Structured around problems designers face “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” • Not created or invented, but harvested • A pattern language is composed of patterns in relationship to each other
What is the scope of the genre? • A Pattern Language Christopher Alexander et al 1977 • Design Patterns: Elements of Reusable Object-Oriented Software Eric Gamma et al 1994 • Patterns for HCI Erickson et al 1997 • Pedagogical Patterns Project: Successes in Teaching Object Technology 1998 • DIAC ’02: Shaping the Network Society: patterns for participation, action and change

How is a Pattern Language created? • Small group of like-minded people (effort & will) • Conscious effort over time (forging shared – if not “agreed” – value system) • Considerable domain expertise (experience, empirical, studies, theoretical & bibliographic knowledge etc.)
