Design- Based Research

This article is about design based research.In this chapter, he presented two design based research projects in order to highlight the notion of theory-in-action as a core focus of this type of work. In the first example, he described how they used our design work to illuminate the limitation in their thinking with respect to a theory about evolving online community.Using the second example, he illustrated how they used design-based research to evolve a theoretical framework called learning engagement theory.

At the core of this design-based work is the conviction that because these innovations are informed by a particular theoretical perspective, the continual testing and refinement of what works can inform both theory and practice.Design-based research (DBR) is used to study learning in environments which are designed and systematically changed by the researcher. The goal of DBR is to use the close study of a single learning environment, usually as it passes through multiple iterations and as it occurs in naturalistic contexts, to develop new theories, artifacts, and practices that can be generalized to other schools and classrooms.

It is especially useful for understanding the underlying reasons why something is happening, or the conditions under which a particular interaction or occurrence could happen.DBR is the belief that the “factoring assumption” of experimental psychology is not valid in learning environments.
  In addition to understanding learning in complex environments and engineering new learning environments, DBR accomplishes. It improves learning for those participants in the study.

Questions: 1-How should teachers  be trained to design-based research?
                2-What are the negative aspects of the design-based research  ?
