Mixed methods research and analysis., Students' names: Vicente…
Mixed methods research and analysis.
Philosophical assumptions and issues associated
Transformative
Guided by the principles of socal justice.
Pragmatic
What has practical and functional value is ultimately important and valid.
Is knowledge constructed from many from many sources in a holistic fashion, or is it a single, concrete truth based on a proven hypothesis or cause and effect?
What is it?
Recognized as a legitimate approach around the 20th century.
Research method that involves collecting, analyzing, and interpreting quantitative and qualitative data.
Meaningful integration of qualitative an quantitative methods.
Generate more credible and persuasive conclusions about the research issue.
Tashakkori and Creswell (2007).
Investigators collect and analyze data, integrate the findings, and draw inferences using both qualitative and quantitative approaches or methods in a single study or a program of inquiry.
Design and conduct a MMR study
Ivankova and Creswell (2009) steps to follow when designing and conducting an MMR study
Determine if MMR is the best approach.
Select an specific mixed methods design to best address the problem.
Write a detailed mixed methods purpose statement that reflects the intent of the study and guides the selection of the methods.
Write specific research questions to address the queantitative and qualitative components of the study.
Choose the quantitative and qualitative data to collect.
Collect and analyse qualitative and quantitative data for the study.
Write the final report reflecting the mixed methods design used in the study.
MMR designs
Conqurrent Quan + Qual MMR design
Characteristics
Used when it's necessary to compare or merge quantitative and qualitative results to produce well-validated conclusions.
Quantitative and qualitative data are collected and analysed independently from each other.
Advantages
Both quantitative and qualitative data can be collected and analysed within a short period of time.
Helps save time and costs for conducting the study.
Well-validated and substantiated findings.
Limitations
Challenging for a sole researcher.
Sequential Quan --> Qual MMR design
Characteristics
It consists of two chronological strands with a quantitative strand occurring first in sequence.
Mostly used when the research problem and related purpose require examination by quantitative methods.
Results from both study strands are interpreted together.
Advantages
The chronological nature of the quentitative and qualitative data collection and analysis makes it more straight forward and easy to implement by one researcher.
Provides an opportunity for the exploration of the initial quantitative results in more detail.
Limitations
A second approval from the institution's ethical review board is needed once the first quantitative strand is completed
May extend the overall time of the study.
Related to the lenght of time and feasibility of resources to collect data and analyse both sets of data.
Sequential Qual --> Quan MMR design
Characteristics
Used when it's necessary to use intial qualitative data to develop new measures and identify unknown variables and relationships.
Two chronological strands with a qualitative strand occurring first in sequence.
Limitations
May require lenghty time and more resources to collect and analyse both sets of data.
Developing of a measurement instrument can be a complicated process.
Seeking another approval from the institution's ethical review board.
Advantages
More straightforward and easy to implement by one researcher.
Advantageous for situations when a researcher wants to explore the phenomenon in depth with a few individuals and wants to expand these findings to a larger population.
Issues to consider
Ensure that the study produces accurate or valid conclusions.
MMR design characteristics.
Concurrent and sequential timing of quantitative and qualitative data collection and analysis.
The order of quantitative and qualitative study strands in sequential designs.
Type of mixing procedures.
Assessing the quality of an MMR study can be challenging because of the intended mixing of results from qualitative and quantitative studies.
Considerations of ethical issues.
Obtaining an approval for the research protocol from the institution's ethical review board.
Ensure voluntary participation and preserving the anonimity and confidentiality of the participants.
Secure infromed consent from study participants.
A true MMR study requires mixing of qualitative and quantitative methods at different stages in the study process.
Methodological characteristics
The key to succesfully use a MMR is to understand that it has a distinct methodology different of other approaches of research.
These characteristics or methodological dimensions refer to the number of quantitative and qualitative study strands and the timing, weighting and mixing of quantitative and qualitative methodos.
STRAND: component of an MMR study that encompasses the basic process of conducting.
TIMING: Temporal relationship between the quantitative and one qualitative strand.
WEIGHTING: relative importance of quantitative and qualitative methods for answering the study's research questions.
Why we use it?
Reasons
Triangulation
To seek corroboration of results from different methods.
Complementarity
To seek clarification of the results from one method with the results from the other method.
Development
To use the results from one method to help develop or inform the other.
Initiation
To seek the discovery of new perspectives from one method with questions or results from the other method.
Expansion
To extend the breadth and range of inquiry by using different methods for different inquiry components.
Benefits for applied linguistics.
Combining methods compatible with the discipline to gain comprenhensive answers to research questions
Employing qualitative methods to determine the meaning and understanding of constructs and quantitative methods assessing the magnitude and frecuency of constructs.
Combining both methods to draw on the strenght of each.
Framing the investigation with synergistic philosophical and theoretical positions.
Work more inclusively to study phenomena across disciplines.
