Developments (last 20 years)
Increasing interest in and advocacy for mixed methods
Evolving understanding of what is mixed methods research
Developing designs and innovative techniques
“The emergence of mixed methods as a third methodological movement in the social and behavioral sciences began during the 1980’s.”
Mixed methods is not that different from other methods
Mixed Methods within Designs
What is this Method Called?
Multi-method Triangulation Integrated Combined Quantitative and qualitative methods Multi-methodology Mixed methodology Mixed-method Mixed research Mixed methods
Mixing (How)
Mixing – Why? Validity – to corroborate quan and qual data Offset – offset weaknesses of quan and qual and draw on
strengths Completeness – more comprehensive account that qual or
quan alone Process – quan provides outcomes; qual, the processes Explanation – qual can explain quan results or vice-versa Unexpected results – surprising results from one, other
explains Instrument development – qual employed to design
instrument Credibility – both approaches enhance integrity of findings Context – qual provides context; quan provides general. Utility – more useful to practitioners
“Single” Paradigm Stance Pragmatism (Tashakkori & Teddlie, 2003)
Focus on research question What “works,” consequences Multiple methods – large toolkit
Transformative (Mertens, 2003) Transform lives of underrepresented, marginalized groups Incorporate this focus into all phases of research
Developing Designs and Innovative Techniques
Notation Typologies Diagrams of procedures Complex evaluation models Reconceptualizing designs Emergence of innovations in procedures
Unusual blends Methodological issues Data analysis techniques Presentation techniques
Key Developments
Preliminary Design ConsiderationsApproach Type Purpose Limitations Resolutions
QUAL + quan Simultaneous Enrich description of sample
Qualitative sample
Utilize normative data for comparison of results
QUAL Sequential Test emerging H, determine distribution of phenomenon in population
Qualitative sample
Draw adequate random sample from same population
QUAN + qual Simultaneous To describe part of phenomena that cannot be quantified
Quantitative sample
Select appropriate theoretical sample from random sample
QUAN Sequential To examine unexpected results
Quantitative sample
Select appropriate theoretical sample from random sample
