Research Methods
Inductive Approaches:• Personal Retrospection: Individual contributions• Sociological: Interviewing others• Mining workshops: Community contributions• Artifactual: Observe and analyze
Kerth und Cunningham, 1997; DeLano, 1998
Deductive Approaches:• By pure argument: Derive new patterns• Experimental: Testing existing patternsAlexander, 1979

CAL 2009 The challenges of the design patterns paradigm for the development of learning environments and experiences
Agreement on findings
Incompletee.g. describing an onlinetraining but leaving out some essential elements
Too abstracte.g. describing an online training only in terms that apply to all web events
Pattern in the world:recurrent structuree.g. the essence ofonline trainings
Agreement on form
Agreement on function
Agreement on aestheticssubjective
objective

Confidence
0: Just a theory. A proposed solution structure.1: Just a design. An actual solution structure.2: A re-tested design. Maybe just coincidence?3: A recurrent design. A Pattern.

Usefulness
General Patterns
Interesting Design Patterns
All recurrent structure
Generative solutions toproblems appropriatefor fitting contexts
Non-trivial, not obviousUsefull and applicable
