Abstract: | For conducting practice oriented research different research strategies are available. In this paper a typology is developed
for differentiating between practice oriented research strategies that are data based and participatory research strategies.
The former category involves quantitative and qualitative data based research strategies. The latter category, participatory
research strategies, includes knowledge based research and practice based research. At present, methodological criteria for
assessing the quality of practice oriented research heavily rely on those developed for theory oriented research, in particular
internal and external validity and reliability. However, we argue that for assessing the results of practice oriented research
other criteria are necessary. In this paper, methodological criteria are formulated for evaluating the internal validity and
practical utility of practice oriented research with the help of a Delphi study using research methodologists as experts.
They agree upon the criteria of verifiability, comprehensibility and acceptance of the results, as well as holism. Moreover,
different categories of participatory and data based research strategies are compared to these criteria. Practice based research
and qualitative data based research are best equipped to fulfill these criteria. These findings may enable researchers to
make a more deliberate choice for a specific research strategy in practice oriented research. |
