Design science

Definition

• Design sciences related to disciplines that build things.

• See also: Design methodology, Design rule

Key elements of design-oriented approaches

(according to Pertti Järvinen, 2004)

1. Technological rules
   • tell you how to do things and are dependant on other theories (and beliefs)
   • Bunge (quoted by Järvinen:99): "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".
2. Types of outcomes (artifacts, interventions):
   • Constructs (or concept) form the " language " of a domain
   • Models are sets of propositions expressing relationships among constructs
   • Methods are a set of steps to perform a task (guidelines, algorithms)
   • Instantiations are realizations of an artifact in its environment
3. Types of research:
   • Build: Demonstrate feasibility of an artifact or intervention
   • Evaluate: Development of criteria, and assessment of both artifact building and artifact usage

What does this mean ?

• There are 4*2 ways to lead interesting design research.
• Usually, it's the not the artefact (i.e. program or course) you build that is interesting, but something behind it (constructs, models, methods, ...) or around it (conditions, perceptions, usage, ...).

Here is picture that shows some of the relationsships between elements of a design process:

• A researcher can investigate at least on of the dotted lines
• A design rule (technological rule in terms of Järvinnen) is a theory on how to build things. It be input, output or both in a research project. See also design-based research that has become popular in educational technology research.
• See instructional design models and instructional design method for designs and methods related to education.

The status of theory

Theories are design artefacts. The outcome of research is often formulated as theory; that is,

highly universal representations, pretending to be independent of concrete context, practice or situation. From the point of view of design, theories are design artefacts, taking different roles in design; from worldviews, guiding the designer and helping him assess the situations and keep the goals in mind, to tools mediating the achievement of specific results. In this way, the direct outcomes of research mediate design. (Bertelsen, :23).
