Design rule

## Definition[edit | edit source]

* A design rule is a theory on how to build things an artefact of a given kind. (Note DSchneider is not sure whether we should use singular or plural for a set of several connected rules ...)

* "A technological rule: an instruction is defined as a chunk of general knowledge, linking an intervention or artifact with a desired outcome or performance in a certain field of application". Bunge (quoted by Järvinen:99)

* Synomyms: technological rule, design principle

See also: design science, design-based research

## Design rules in educational technology[edit | edit source]

In our opinion (DSchneider), the design rule should be the focal point of action-research oriented research designs like design-based research. Therefore we need some clear guidelines on:

* how to create design rules
* how to implement design rules
* how to test design rules

.... and how to to combine these within iterative, user-centered research and development approaches.
