Qualitative and Quantitave research and DBR

It has been a long time that rsearchers in social sciences should determine that using which one of the Qualitative or Quantitative approaches they are going to embark and run their research. Using deterministic numerical methods and statistical analysis is normally called quantitative approacha nd using illuminative arguments and describing the events is qualitative approach. In the latter one the researcher is normally immersed in the real world situation and observe the case and tries to describe the phenomenon which is being studied. However, in the former one - quantitative - researcher is normally works in his office and analysed the numerlised data using statistical techniques.
Recently, many reserachers began to use mixed approaches which is quite appropriate for analysing and describing the social sciences phenomena. I was thinking is it the time to get rid of these terminology and try to find some practical and comprehensive approaces. Obviously answering to this question is not an easy job. However,using new and advanced methodologies are pretty useful to achieve that point. One of these methodologies is DBR (Design-Based Rresearch) methodology. DBR let researcher to use any appropriate tactic and technique in different stages of test and modificition. Simply, it is a cycle of design a tactic to attack the research question, test it, modify it, and redesign the tactic, and another test and modify, etc. This process of test and modification can be done in any format whether qualitative or quantitative.

To have a inclusive source for DBR I'd like to refer you to Educational Researcher 2003.
