Qualitative Research: Design, Methods, & Online Mode

In 2020, there were 14 articles published in Research Design Review. These articles include those qualitative research design, methods, online modepertaining to broad issues in qualitative research design, such as sample size, as well as more narrow topics concerning specific qualitative methods – focus groups, ethnography, in-depth interviews, and case study research – and the online mode. A compilation of these articles is now available here for download.

In addition to these 14 articles, six compilations of earlier RDR articles were released in 2020 for download. These include:

Generalizability in Case Study Research

Portions of the following article are modified excerpts from Applied Qualitative Research Design: A Total Quality Framework Approach (Roller & Lavrakas, 2015, pp. 307-326)

Case study research has been the focus of several articles in Research Design Review. These articles range from discussions on case-centered research (i.e., case study and narrative research) generally — “Multi-method & Case-centered Research: When the Whole is Greater Than the Sum of its Parts,” “Lighting a Path to Guide Case-Centered Research Design: A Six-Step Approach,” and “Ethical Considerations in Case-Centered Qualitative Research” — to articles where the subject matter is specific to case study research — “Case Study Research: An Internal-External Classification.”generalizability

One of the controversies associated with case study research designs centers on “generalization” and the extent to which the data can explain phenomena or situations outside and beyond the specific scope of a particular study. On the one hand, there are researchers such as Yin (2014) who espouse “analytical generalization” whereby the researcher compares (or “generalizes”) case study data to existing theory1. From Yin’s perspective, case study research is driven by the need to develop or test theory, giving single- as well as multiple-case study research explanatory powers — “Some of the best and most famous case studies have been explanatory case studies” (Yin, 2014, p. 7).

Diane Vaughan’s research is a case study referenced by Yin (2014) as an example of a single-case research design that resulted in outcomes that provided broader implications (i.e., “generalized”) to similar contexts outside the case. In both The Challenger Launch Decision: Risky Technology, Culture, and Deviance at NASA (1996) and “The Trickle-Down Effect: Policy Decisions, Risky Work, and the Challenger Tragedy” (1997), Vaughan describes the findings and conclusions from her study of the circumstances that led to the Challenger disaster in 1986. By way of scrutinizing archival documents and conducting interviews, Vaughan “reconstructed the history of decision making” and ultimately discovered “an incremental descent into poor judgment” (1996, p. xiii). More broadly, Vaughan used this study to Read Full Text

Case-Centered Research in Education: Bridging the Cultural Divide

The following is a modified excerpt from Applied Qualitative Research Design: A Total Quality Framework Approach (Roller & Lavrakas, 2015, pp. 329-331). This excerpt discusses a case study illustrating how the author utilized many Total Quality Framework (TQF) design considerations, e.g., disclosure of the sampling method, a discussion of researcher bias, and processing plus verification procedures, that ultimately led to useful outcomes.

Bridging the cultural divideMultiple methods and case-centered qualitative research is the subject of other articles in Research Design Review – see “Multi-method & Case-centered Research: When the Whole is Greater Than the Sum of its Parts.” Multiple methods, of course, refers to combining two or more qualitative methods to investigate a research question. Case-centered research is

A term coined by Mishler (1996, 1999) to denote a research approach that preserves the “unity and coherence” of research subjects throughout data collection and analysis. It consists of two fundamental and unique components: (a) a focus on the investigation of “complex” social units or entities (also known as “case[s]”) in their entirety (i.e., not just one aspect captured at one moment in time), and (b) an emphasis on maintaining the cohesiveness of this entity throughout the research process. Two prominent case-centered approaches are case study research and narrative research. (Roller & Lavrakas, 2015, p. 350).

The following case study is from Auerbach (2002) who used multiple methods within a case-centered narrative study design to explore schooling and communication with educators among working-class Latino parents in urban Los Angeles. This case is discussed around the four components of the TQF – Credibility, Analyzability, Transparency, and Usefulness.


The purpose of this research was to explore the problems that Latino parents in urban Los Angeles face related to the schooling of their children and communication with educators. More specifically, this research utilized one particular college-access program for high school students to investigate the use of storytelling among a marginalized group of working-class Latino parents to examine whether “listening to the stories of parents of color may help urban educators and policy makers bridge the divide between students’ home cultures and the culture of school” (p. 1370).


A case-centered approach is a popular form of qualitative research among educational researchers. Stake (1995), Qi (2009), Bennett et al. (2012), Clandinin and Connelly (1998; Connelly & Clandinin, 1990), and Randall (2012) are just a few of the researchers who have applied either case study or narrative research to issues in education. The study presented here is another example of case-centered research in an educational setting. This was a fitting approach, given the researcher’s access to and involvement with the “Futures Project”—a longitudinal study conducted in conjunction with
an experimental college-access program for high school students—which fostered a case-centered study design relying on multiple methods within a narrative framework.


The target population for this study was parents of high school students participating in the Futures Project. This project was conducted in partnership with UCLA to trace the trajectories of 30 students who participated in an experimental college-access program. The researcher used Read Full Text
