Case study, grounded theory, phenomenology and other research methodologies

Qualitative research methodologies function as optional “templates” for designing a study—offering guidance on aims, context, data collection, and data analysis without forcing researchers into a single rigid path. The core takeaway is that researchers can choose a methodology when it fits their question, mix elements across approaches, or even build something entirely their own, as long as the design supports the kind of understanding they’re seeking.

A methodology is more than a label; it bundles key study components such as the focus of inquiry, the study’s aims, the circumstances under which research occurs, and the methods used to gather and analyze data. That flexibility matters because different questions demand different lenses. For instance, if the goal is to understand what it feels like to live through a particular experience, phenomenology provides a structured approach. If the goal is to develop a theory—especially about phenomena that are relatively under-researched—grounded theory offers procedures designed to generate explanations from data rather than from prior assumptions.

The transcript also pushes back against a common misconception: researchers do not have to pick one “template” and follow every rule. Methodologies can be adapted. Researchers can borrow specific elements, combine approaches, or adjust procedures to fit their study’s needs. This adaptability is presented as a practical advantage rather than a threat to rigor.

Among the most common methodologies, ethnography centers on immersion in a community or culture. Historically tied to studying groups like tribes or gangs, the approach now extends to any bounded social setting—schools, workplaces, or factories. The defining feature is interaction with participants in their natural environment, with data often gathered through observation, field notes, and interviews.

Phenomenology focuses on lived experience and the meaning of an experience from the participant’s perspective. It aims to uncover the essence of experiences such as trauma, typically relying on in-depth interviews as a primary method.

Grounded theory is framed as less intimidating than it sounds, but methodologically demanding. It targets the generation of theory or detailed explanation for topics that lack strong prior understanding. A key characteristic is an inductive stance: researchers aim to avoid being driven by pre-existing theories and instead build concepts from the data. Analysis is described as highly detailed, often involving line-by-line coding and constant comparison—repeatedly moving back and forth during analysis. The method can also include theoretical sampling, where additional participants are recruited as the emerging explanation develops.

Case study is defined by depth and boundaries: it investigates a bounded system—an individual, group, institution, class, or even a city—using multiple data collection methods to capture diverse perspectives. The transcript warns that “case study” is frequently overused; simply interviewing a few people doesn’t automatically meet the approach’s core requirement of triangulating perspectives.

Narrative research centers on individual stories and the meanings people construct through storytelling, often using storytelling interviews or life narratives and paying attention both to language and story structure. Finally, action research is oriented toward change: it involves planning an intervention, implementing it, and reflecting on results in iterative cycles—commonly used in education and organizational settings to improve real-world practice.
