Case Study vs. Ethnography

What's the difference.

Case study and ethnography are both research methods used in social sciences to gain a deeper understanding of a particular phenomenon or group of people. However, they differ in their approach and focus. A case study typically involves an in-depth examination of a single individual, group, or event, aiming to provide a detailed analysis of a specific situation. On the other hand, ethnography involves immersing oneself in a particular culture or community over an extended period, observing and interacting with its members to understand their beliefs, behaviors, and social dynamics. While case studies provide detailed insights into specific cases, ethnography offers a broader understanding of the cultural context and social interactions within a community.

Further Detail

Introduction.

Case study and ethnography are two research methods commonly used in social sciences and other fields to gain a deeper understanding of a particular phenomenon or group of people. While both methods aim to provide rich and detailed insights, they differ in their approach, scope, and data collection techniques. In this article, we will explore the attributes of case study and ethnography, highlighting their similarities and differences.

Definition and Purpose

Case study is a research method that involves an in-depth examination of a specific individual, group, or event. It aims to provide a comprehensive analysis of a particular case, often focusing on a unique or rare occurrence. On the other hand, ethnography is a qualitative research method that involves immersing the researcher in the natural environment of a group or community to observe and understand their culture, behaviors, and social interactions.

Scope and Generalizability

One key difference between case study and ethnography lies in their scope and generalizability. Case studies are typically more focused and specific, aiming to provide detailed insights into a particular case or situation. The findings of a case study may not be easily generalized to a larger population due to the uniqueness of the case being studied.

On the other hand, ethnography aims to capture the broader cultural and social dynamics of a group or community. By immersing themselves in the natural setting, ethnographers can observe and document the behaviors, beliefs, and practices of the group. Ethnographic research often seeks to uncover patterns and themes that may be applicable to similar groups or communities, allowing for a higher level of generalizability.

Data Collection

Another important aspect to consider when comparing case study and ethnography is their data collection techniques. In case studies, researchers often rely on multiple sources of data, including interviews, surveys, observations, and document analysis. These various data sources help provide a comprehensive understanding of the case being studied.

On the other hand, ethnography primarily relies on participant observation, where the researcher actively engages with the group being studied, often for an extended period. This immersive approach allows the researcher to gain firsthand experience and insights into the culture, norms, and practices of the group. Ethnographers may also conduct interviews and collect artifacts or documents to supplement their observations.

Time and Resources

Case studies and ethnography also differ in terms of the time and resources required to conduct the research. Case studies are often more time-efficient, as they focus on a specific case or event. Researchers can collect data relatively quickly and analyze it in a shorter timeframe. However, the depth of analysis and the level of detail may vary depending on the complexity of the case.

On the other hand, ethnography is a time-consuming process that requires a significant investment of time and resources. Researchers need to spend an extended period in the field, building rapport with the community, and gaining their trust. The immersive nature of ethnography allows for a more comprehensive understanding of the group, but it also demands a longer-term commitment from the researcher.

Analysis and Interpretation

Both case study and ethnography involve a detailed analysis and interpretation of the collected data. In case studies, researchers often employ various analytical frameworks or theories to make sense of the data and draw conclusions. The analysis may involve identifying patterns, themes, or causal relationships within the case being studied.

Similarly, ethnographic research involves a rigorous analysis of the collected data. Ethnographers often engage in a process called coding, where they categorize and organize the observations, interviews, and other data sources. This coding process helps identify recurring themes, cultural practices, and social dynamics within the group. Ethnographers may also use theoretical frameworks to interpret their findings and provide a deeper understanding of the observed phenomena.

Applications

Both case study and ethnography have diverse applications across various disciplines. Case studies are commonly used in psychology, business, medicine, and law to examine individual cases, diagnose specific conditions, or understand unique situations. They provide valuable insights into complex phenomena that cannot be easily replicated or studied through other research methods.

On the other hand, ethnography finds its applications in anthropology, sociology, cultural studies, and other social sciences. Ethnographic research allows for a holistic understanding of different cultures, communities, and social groups. It helps uncover the underlying meanings, values, and practices that shape the lives of individuals within a specific cultural context.

In conclusion, case study and ethnography are two distinct research methods that offer valuable insights into specific cases or cultural contexts. While case studies provide a detailed analysis of a particular case, ethnography allows for a broader understanding of social and cultural dynamics. Both methods have their strengths and limitations, and the choice between them depends on the research objectives, scope, and available resources. By employing these research methods appropriately, researchers can gain a deeper understanding of the complexities of human behavior, culture, and society.

Difference Between Case Study and Ethnography

Main difference – case study vs ethnography.

Case studies and ethnographies are two popular detailed, qualitative studies used in the field of social science . Although there are certain similarities between these two methods such as their holistic nature, and the extended time period, there are also some differences between the two. The main difference between case study and ethnography is their focus; ethnography aims to explore cultural phenomenon whereas case studies aim to describe the nature of phenomena through a detailed investigation of individual cases.

What is a Case Study

A case study is a detailed investigation of a single event, situation or an individual in order to explore and unearth complex issues. Yin (1984) defines case study as “an empirical inquiry that investigates a contemporary phenomenon within its real-life context; when the boundaries between phenomenon and context are not clearly evident; and in which multiple sources of evidence are used.” Although case studies are always associated with qualitative research, they can also be quantitative in nature. They are often used to explore community-based issued such as poverty, illiteracy, unemployment, prostitution, and drug addiction.

A successful case study is context-sensitive, holistic, systematic, layered and comprehensive. The process of a case study involves,

• Identifying and defining the research questions
• Selecting the cases and deciding techniques for data collection and analysis
• Collecting data in the field
• Evaluating and analysing the data
• Preparing the report

Data collection methods in a case study may involve interviews, observations, questionnaires, checklists, analysis of recorded data and opinionnaires. Case studies can also be divided into different categories. Exploratory, descriptive and explanatory case studies are three such categories.

Case studies are preferred by many researchers in the field of social sciences since they offer detailed and in-depth information about a particular phenomenon. However, it is difficult to use the data obtained from a case study to form generalisation since it only focuses on a single event or phenomenon.

Figure 1: Questionnaires are one method of data collection in a case study.

What is an Ethnography

Ethnography is a detailed and in-depth study of everyday life and practice. In other words, it is the systematic study of people and cultures. A researcher who is engaged in ethnography is known as an ethnographer . Ethnographers explore and study culture from an insider’s point of view (emic perspective).

Ethnography traditionally involved focusing on a bounded and a definable race, ethnicity or group of people; for example, study of a particular African tribe. However, modern ethnography also focus on different aspects of the contemporary social life.

Ethnographic research mainly involves field observations, i.e., observations of behaviour in a natural setting. The researchers have to spend a considerable amount of time inside a community in order to make such observations. Information about particular socio-cultural phenomena in a community is typically obtained from the members of that particular community. Participant observation and interviews are two of the main data collection methods in this type of studies. Ethnographic studies take a longer period of time than other types of research since it takes long-term involvement and observation to understand the attitudes, beliefs, and behaviours of a community.

Figure 2: Observation and participant interviews are main data collection methods in ethnography.

Definition 

Case Study: A case study is a detailed investigation of a single event, situation or an individual in order to explore and unearth complex issues.

Ethnography: An ethnography is the detailed and systematic study of people and cultures.

Case Study: Case studies focus on a single event, incident or individual.

Ethnography: Ethnography observes cultural phenomenon.

Case study: Case study intends to uncover the tacit knowledge of culture participants.

Ethnography: Ethnography aims to describe the nature of phenomena through detailed investigations of individual cases.

Data Collection Methods

Case Study: Case studies may use interviews, observations, questionnaires, checklists, analysis of recorded data and opinionnaires.

Ethnography: Ethnographic studies use participant observations and interviews.

Special Requirements

Case Study: The researcher does not have to live in a particular community.

Ethnography: The researcher has to spend a considerable amount time inside that particular community.

Conclusion 

Case study and ethnography may have some similarities; however, there is a considerable difference between case study and ethnography as explained above. The main difference between case study and ethnography lies in their intent and focus; case studies intend to uncover the tacit knowledge of culture participants whereas ethnographic studies intend to describe the nature of phenomena through detailed investigations of individual cases. There are also differences between them in terms of data collection and analyis.

Difference between case study & ethnography

Introduction

In the social sciences, case study and ethnography are two popular research methodologies. While there are similarities between the two, there are also differences in data collection and the overall purpose of the study. This article aims to clarify these differences.

A case study is an in-depth study of a particular instance, event, individual, or group. It can be explanatory or descriptive in nature, but its focus is on understanding the why’s and implications of the subject of study. Case studies draw conclusions based on prior research and systematic analysis of data.

Ethnography

Ethnography is the art and science of describing a group or culture. It is an investigative approach that requires the ethnographer to behave like a neutral observer, without imposing personal viewpoints or making subjective judgments. Participant observation is often used as a method of data collection in ethnography, where the ethnographer becomes a part of the group being studied and records observations without analysis.

Differences

– Ethnography focuses on describing a group or culture, while a case study focuses on a particular instance, event, individual, or group. – Ethnography requires participant observation as a data collection method, while it is not necessary for a case study. – A case study is more outward looking, focusing on the why’s and implications, whereas ethnography is more inward looking. – Ethnography takes a longer time to conduct than a case study.

In summary, a case study is an in-depth analysis of a specific subject, while ethnography is an in-depth study of a group or culture. The methods of data collection and the perspectives of analysis differ between the two methodologies.

Key Takeaways

1. The difference between a case study and ethnography is that ethnography is a study of a culture or ethnic group, while a case study investigates a particular instance, event, or individual. 2. Ethnography requires participant observation as a data collection method, while it is not necessary in a case study. 3. A case study is more outward-looking, focusing on the why’s and implications of an event, while ethnography is more inward-looking and focused on describing a group or culture.

Ethnographic Case Studies

Description

This research guide discusses ethnographic case study. While there is much debate over what, precisely, delimits a case study , the general consensus seems to be that ethnographic case studies differ from other types of case studies primarily in their focus, methodology, and duration. In essence, ethnographic case studies are case studies “employing ethnographic methods and focused on building arguments about cultural, group, or community formation or examining other sociocultural phenomena” (Schwandt & Gates, 2018, p. 344), typically with a long duration, per the demands of ethnographic work. In essence, ethnographic case studies are case studies “employing ethnographic methods and focused on building arguments about cultural, group, or community formation or examining other sociocultural phenomena” (Schwandt & Gates, 2018, p. 344), typically with a long duration, per the demands of ethnographic work. Indeed, in its very situatedness, ethnography has a “case study character” and is “intimately related” to case studies (Ó Rian, 2009, p. 291); though there is currently a move to extract ethnographic work from overly situated contexts and use extended case methods, “[e]thnographic research has long been synonymous with case studies, typically conceived of as grounded in the local and situated in specific, well-defined and self-contained social contexts” (Ó Rian, 2009, p. 290). Because ethnography, in practice, is often a kind of case study, it’s useful to consider ethnography and case studies each in their own right for a fuller picture of what ethnographic case study entails.

Ethnographic research is one approach under the larger umbrella of qualitative research. Methodologically, it is, “a theoretical, ethical, political, and at times moral orientation to research, which guides the decisions one makes, including choices about research methods” (Harrison, 2014, p. 225), that is at its crux “based upon sharing the time and space of those who one is studying” (Ó Rian, 2009, p. 291)–a situated, nuanced exploration seeking a thick description and drawing on methods such as observation and field notes. According to …an ethnography focuses on an entire culture-sharing group and attempts to develop a complex, complete description of the culture of the group. Creswell and Poth (2018), an ethnography focuses on an entire culture-sharing group and attempts to develop a complex, complete description of the culture of the group. In doing so, ethnographers look for patterns of behavior such as rituals or social behaviors, as well as how their ideas and beliefs are expressed through language, material activities, and actions (Creswell & Poth, 2018). Yin (2016)  suggests that ethnographies seek “to promote embedded research that fuses close-up observation, rigorous theory, and social critique. [Ethnographies foster] work that pays equal attention to the minutiae of experience, the cultural texture of social relations, and to the remote structural forces and power vectors that bear on them” (p. 69).

Case study research, meanwhile, is characterized as an approach “that facilitates exploration of a phenomenon within its context using a variety of data sources” (Baxter & Jack, 2008, p. 544). The aim of case studies is precise description of reconstruction of cases (Flick, 2015). The philosophical background is a qualitative, constructivist paradigm based on the claim that reality is socially constructed and can best be understood by exploring the tacit, i.e., experience-based, knowledge of individuals. There is some debate about how to define a The philosophical background is a qualitative, constructivist paradigm based on the claim that reality is socially constructed and can best be understood by exploring the tacit, i.e., experience-based, knowledge of individuals. “case” (e.g., Ó Rian, 2009), however. As Schwandt and Gates (2018) write, “[A] case is an instance, incident, or unit of something and can be anything–a person, an organization, an event, a decision, an action, a location”; it can be at the micro, meso, or macro level; it can be an empirical unit or a theoretical construct, specific or general; and in fact, “what the research or case object is a case of may not be known until most of the empirical research is completed” (p. 341). The two authors conclude that given the multifarious interpretations of what case study is, “[b]eyond positing that case study methodology has something to do with ‘in-depth’ investigation of a phenomenon . . . , it is a fool’s errand to pursue what is (or should be) truly called ‘case study’” (p. 343, 344).

In this how-to article, the authors present an argument for the use of a blended research design, namely the Ethnographic Case Study, for student researchers. To establish their point of view, the authors reiterate recognized research protocols, such as choosing a design that suits the research question to ensure data saturation. Additionally, they remind their reader that one must also consider the feasibility of the project in terms of time, energy, and financial constraints.

Before outlining the benefits and components of the Ethnographic Case Study approach, the authors provide detailed narratives of ethnographic, mini-ethnographic (sometimes referred to as a focused ethnography ), and case study research designs to orient the reader. Next, we are introduced to the term mini-ethnographic case-study design, which is defined as a blended design that is bound in time and space and uses qualitative ethnographic and case study collection methods. The benefits of such an approach permit simultaneous generation of theory and the study of that theory in practice, as it allows for the exploration of causality.

Ethnographic Case Study research shares many characteristics with its parent approaches.  For example, subjectivity and bias are present and must be addressed. Next, data triangulation is necessary to ensure the collected qualitative data and subsequent findings are valid and reliable. Data collection methods include direct observation, fieldwork, reflective journaling, informal or unstructured interviews, and focus groups. Finally, the authors discuss three limitations to the ethnographic case study. First, this design requires the researcher to be embedded, yet the duration of time may not be for as long when compared to full-scale ethnographic studies.  Second, since there are fewer participants, there should be a larger focus on rich data as opposed to thick data, or said differently, quality is valued over quantity. Third, the researcher must be aware that the end-goal is not transferability, but rather the objective is to gain a greater understanding of the culture of a particular group that is bound by space and time.

Gregory, E. & Ruby, M. (2010) The ‘insider/outsider’ dilemma of ethnography: Working with young children and their families in cross-cultural contexts. Journal of Early Childhood Research, 9 (2), 1-13. https://doi.org/10.1177/1476718X10387899

This article focuses on the dilemma of insider and outsider roles in ethnographic work. It challenges the notion that a researcher can be both an insider and an outsider at the same time. There is no insider/outsider status; it is one or the other–not both.

It is easy to make assumptions about one’s status as an insider. It is not uncommon for a researcher to assume that because one is working amongst his/her “own” people sharing a similar background, culture, or faith that she/he is an insider. Likewise, a researcher may assume that it will be easy to build rapport with a community with which he/she has commonalities; however, it is important to keep in mind that the person may be an insider but the researcher may not have this same status. When the person enters into the protective space of family or community as a researcher, it is similar to being an outsider. Being a researcher makes one different, regardless of the commonalities that are shared. It is not the researcher’s presumed status of “insider” or “outsider” that makes the difference; rather, researcher status is determined by the participants or community that is being studied. It is wise for researchers to understand that they are distinctively one of “them” as opposed to one of “us”. This is not to say that researchers cannot become an “insider” to some degree. But to assume insider status, regardless of the rationale, is wrong. Assuming common beliefs across cultures or insider status can lead to difficulties that could impact the scope or nature of the study.

In conclusion, regardless of the ethnographic design (e.g., realist ethnography, ethnographic case study, critical ethnography), it is important for the researcher to approach the study as an “outsider”. Although the outsider status may change over time, it essential to understand that when one enters a community as a researcher or becomes a researcher within a community, insider status must be earned and awarded according to the participants in the community.

Ó Rian, S. (2009). Extending the ethnographic case study. In D. Byrne & C. C. Ragin (Eds.), The SAGE handbook of case-based methods (pp. 289–306). Thousand Oaks, CA: SAGE.

In this chapter, Ó Rian valorizes the problems and potential hiding within the vagaries of ethnographic “case” boundaries, arguing that “whereas the fluid and multi-faceted aspects of the ethnographic case pose dilemmas for ethnographers, they can also become resources for ethnographers in exploring theoretical and empirical questions” (p. 292). Indeed, he views the idea of firm case boundaries as a weakness, as “definitions of the case will rule in and out certain social processes,” and suggests ethnography’s flexibility can deal with this problem well because it permits researchers to “question the boundaries of the case as the study proceeds,” leading to a “de- and re-construction of the case that . . . places ethnography at the centre of a resurgent contextualist paradigm of social inquiry . . . that is increasingly self-consciously exploring its own theoretical and methodological foundations” (p. 304). Most of the chapter delves into these possibilities for exploration, offering an insightful (if occasionally difficult to follow) perspective on how they have been proceeding.

The chapter offers considerations that might be particularly helpful to researchers undertaking ethnographic case studies who are struggling to connect their cases, so firmly rooted in a particular context and their own personal experiences and observations, to a bigger picture. Ó Rian elucidates the reflexive strategies various ethnographers have adopted as they’ve sought “[t]o achieve a link between context-specific data and meso- or macro-level generalizations,” categorizing these strategies into three “interlocking extensions of case study research” (p. 292): personal extensions (related to “the shaping of the boundaries of the case by the ethnographer’s location within the field and . . . how ethnographers can convey their personalized experiences and tacit learning to readers” [p. 292]), theoretical extensions (which bridge the gap between the situated worlds being explored and “the larger structures and processes that produced and shaped them” [p. 292]), and empirical extensions (“creative efforts to experiment with the empirical boundaries of the ethnographic case” [p. 292] by bringing in, for example, historical context, social networks, etc.). The crux of his argument is that ethnographic researchers have a prime opportunity to push against the boundaries of their context and “extend their cases across space, time and institutional structures and practices” so that the ethnographer is “multiply, if perhaps a bit uncomfortably, situated” (p. 304), and also to include an “emphasis on the ongoing process of theoretical sampling within the process of the ethnographic study, with close attention to be paid to the paths chosen and rejected, and the reasons for these decisions” (p. 304). These kinds of extensions offer an opportunity for theories to “be refined or reconstructed” as the researcher attempts to locate their personal experience within a broader framework, allowing “[t]he case study . . . to challenge and reconstruct the preferred theory” while also connecting the case to a larger body of work, particularly because theory “carries the accumulated knowledge of previous studies” (p. 296).

Ó Rian’s in-depth descriptions of how other researchers have varyingly handled these personal, theoretical, and empirical extensions might be a bit overwhelming to novice researchers but overall can offer a way to “locate their cases within broader social processes and not solely within their own personal trajectories” (p. 294)–while also helping to situate their reflections and extensions within a larger body of literature replete with researchers struggling with similar questions and concerns.

This chapter offers an  in-depth, generally accessible (but occasionally overwhelming) overview of case studies of all sorts and integrates an extensive review of relevant literature. The authors provide an informed perspective on various considerations and debates in the case study field (e.g., varying definitions of what a “case” is construed to be; interpretive vs. critical realist orientations; the relative benefits of and techniques involved in different types of approaches), helping novice researchers locate and better describe their own approach within the context of the field. The information is quite detailed and delves into a wide variety of case study types, suggesting this chapter might best be first skimmed as an initial introduction, followed by more careful readings of relevant sections and perusal of the key texts cited in the chapter. The breadth of this chapter makes it a helpful resource for anyone interested in case-study methodology.

The authors do not specifically explore ethnographic case studies as a separate type of case study. They do, however, briefly touch on this idea, locating ethnography within the interpretive orientation (comprising constructivist approaches offering “phenomenological attention to lived experience” [p. 344]). The authors also cite researchers who distinguish it due to its “[employing] ethnographic methods and focus on building arguments about cultural, group, or community formation or examining other sociocultural phenomena” (p. 344). Ethnographic case study is placed in contrast to case studies that use non-ethnographic methods (e.g., studies “relying perhaps on survey data and document analysis”) or that “are focused on ‘writing culture’” (p. 344).

Two aspects of this chapter are particularly useful for novice researchers. First, it is worth highlighting the authors’ discussion of varying definitions of what a “case” is, as it can provide an interesting reconceptualization of the purpose of the research and the reason for conducting it. The second noteworthy aspect is the authors’ detailed descriptions of the four main case study uses/designs ( descriptive, hypothesis generation or theory development, hypothesis and theory testing , and contributing to normative theory ), which the authors beautifully align with the respective purposes and methods of each type while also offering insight into relevant conversations in the field.

Recent Dissertations Using Ethnographic Case Study Methodology

Cozzolino, M. (2014). Global education, accountability, and 21st century skills: A case of curriculum innovation . Retrieved from ProQuest Dissertations & Theses Global. (Order Number 3648007)

This dissertation is self-described as an ethnographic case study of a small, public, suburban high school in Pennsylvania. In this study, the researcher investigates the school’s process of integrating global education into its curriculum by implementing a school-wide initiative (Global Studies Initiative or GSI) as well as a program of study (Global Studies Credential or GSC). Cozzolino asserts that her framework has been shaped by both social constructivism and critical/Freirean pedagogy. From the constructivist view, she views knowledge as constructed through social interaction, and thus she sought to understand the world in which the research participants work, learn, and experience large parts of their lives. It is here that she situates the first three research questions that entail looking at the the GSI and the GSC in terms of their features, rationales, and implementations. The fourth question involves understanding the students’ views and perceptions of the GSC and here the author takes up a critical and Freirean pedagogy to honor and hear the voices of the students themselves.

The study design is therefore an embedded single-case study in that it is bound by the place (Olympus High School) and by its population. Furthermore, it is also a case within a case, as it seeks to understand the students’ perspectives of the global programming. The case study is ethnographically rooted through the multiple ethnographic data sources such as participant-observations and a prolonged engagement at the research site. Cozzolino embedded herself in the research site over a five-year period and became an active and invested member of the school community, thereby establishing a sound rationale for an ethnographic case-study approach.

The author concludes that there were some competing priorities about the overall initiative from stakeholders inside and outside the school district. This resulted in a less than ideal implementation of the program of study across the curriculum. Nonetheless, the students who were enrolled in these courses reported it to be a worthwhile experience. While Cozzolino presents specific recommendations for the improvements at Olympus High, she also offers implications for several other groups. First, she provides advice for implementation to other educational institutions that aim to integrate a global focus into their curriculum. Next, she gives recommendations for local, state, and national policy changes. Finally, she gives suggestions for engaging all parties in fruitful discourse to achieve their ultimate goal of implementing a meaningful and valuable global education curriculum.

Hamman, L. (2018). Reframing the language separation debate: Language, identity, and  ideology in two-way immersion . Retrieved from ProQuest Dissertations & Theses Global. (Order Number 2089463322)

This study explored the issues of surrounding language separation in two-way immersion (TWI) classrooms. The author looked at how classroom language practices and teacher ideologies influenced the student experience and how the students’ understanding of what it means to be bilingual is influenced in a classroom that purports to be equitable in terms of language use.

The study is theoretically grounded in sociocultural, critical, and postcultural theories and adapted Lemke’s ecosocial system to conceptualize TWI classroom. Hamman also drew upon translanguaging theory and dynamic bilingualism to provide a framework for a more modern and nuanced perspective of bilingualism, bilingual learning, and bilingual students.

The author combined a single-case study approach with ethnographic methods to “engage in close analysis of classroom language use and the discursive negotiation of identities and ideologies, while situating these analyses within a rich understanding of the sociolinguistic context of this TWI classroom” (p. 78-79). She employed various ethnographic methods such as taking fieldnotes, conducting participant observations, interviewing, and memoing. The study is “bound” in that it takes place in one 2nd-grade classroom with one teacher and 18 students over the course of one year.

Hamman concludes that student perspectives on language separation should be considered, since this forced separation of language influenced how they thought of their developing bilingualism and identity as bilinguals. Furthermore, the study envisages a linguistic “middle ground” to strict separation that allows for appropriate and meaningful spaces for linguistic negotiation. Finally, this dissertation asserts that the strict separation of languages codifies a monoglossic ideology mindset and limits learners’ possibilities for learning and making connections across languages.

This doctoral dissertation takes an ethnographic case study approach to explore the identity formation of transnational Korean youth. The researcher, herself a Korean immigrant to the U.S. navigating complex identity processes, focuses on these research questions: “1) what are the contexts in which migrant youth negotiate their identities? 2) how do youth understand and negotiate their sense of belonging? 3) how do youth’s [sic] cultural and literacy practices inform and shape their identities? 3i) how do youth make use of transnational new media for their identity work? 3ii) how do literacy practices potentially shape their identities?” (p. 7).

Drawing on Leander and McKim (2013), the author conceptualizes her study as a “connective ethnography” (p. 36) encompassing multiple spaces, both digital and physical, in which “space” comprises a variety of relationships, instead of a more traditional ethnography bounded by physical space. The “case study” aspect, meanwhile, refers to the four specific participants in which she chose to focus. She chose Korean immigrants in St. Louis, in general, due to their mobility between the U.S. and Korea, their high use of digital communication and information technology, and their limited access to the cultural resources of Korea in a Midwestern city. From an initial 32 possible participants purposively selected, the researcher chose four focal participants based on their Korean ethnicity, biliteracy in Korean and English, age (between 11 and 19 years old), residence in the U.S. (for at least 2 years), and their use of digital communication technologies. Data sources included an initial screening survey, an identity map each participant created, informal recorded conversations, recorded interviews in either English or Korean, field notes from the researcher’s interactions with the youth in various settings (home, school, community centers), and “literacy documents” (evidence of literacy practices from participants’ school and home, emails to the researcher, or activities in digital spaces). She used social semiotic multimodal discourse analysis and what she describes as “grounded theory thematic analysis” to analyze the data.

This is a reflective, thoughtful, and interesting dissertation. The author carefully notes the relationship between the data sources and her research questions, specifically addresses steps she took to ensure the validity of the data (e.g., triangulation via multiple data sources and theoretical frameworks, member checks, and feedback from her professors and other researchers), and discloses her own positionalities and biases. Her discussion includes not only a clear thematic exploration of her findings but also offers specific practical suggestions for how her findings can be applied and extended in the classroom.

Abalos-Gerard Gonzalez , L. (2011). Ethnographic research . Retrieved from https://www.slideshare.net/lanceabalos/ethnographic-research-2?from_action=save

Created by Lance Gerard G. Abalos, teacher at the Department of Education-Philippines, this SlideShare, Ethnographic Research , explains that, regardless of specific design, ethnographic research should be undertaken “without any priori hypothesis to avoid predetermining what is observed or that information is elicited from informants . . .hypotheses evolve out of the fieldwork itself” (slide 4). It is also suggested that researchers refer to individuals from whom information is gathered as ‘informants’ is preferred over the term ‘participants’ (slide 4).

According to Abalos, “It is not the data collection techniques that determine whether the study is ethnographic, but rather the ‘socio-cultural interpretation’ that sets it apart from other forms of qualitative inquiry” (slide 6). A social situation always has three components: a place, actors, and activities (slide 8) and it is the socio-cultural interpretation of the interactions of these three that is the focus of the ethnographic research.

Ethnographic questions should guide what the researcher sees, hears, and collects as data (slide 9). When writing the ethnography, it is essential to ‘bring the culture or group to life’ through the words and descriptions used to describe the place, actors, and activities.

Abalos describes three types of ethnographic designs:

• Realist Ethnographies : an objective account of the situation, written dispassionately from third-person point of view, reporting objectively on information learned from informants, containing closely edited quotations (slide 11-12).
• Ethnographic Case Studies : researchers focus on a program, event, or activity involving individuals rather than a group, looking for shared patterns that develop as a group as a result of the program, event, or activity (slide 13).
• Critical Ethnographies: incorporating a ‘critical’ approach that includes an advocacy perspective, researchers are interested in advocating against inequality and domination (slide 14).

As ethnographic data is analyzed, in any design (e.g., realist, case study, critical), there is a shift away from reporting the facts to making an interpretation of people and activities, determining how things work, and identifying the essential features in themes of the cultural setting (slide 22). “The ethnographer must present the description, themes, and interpretation within the context or setting of the culture-sharing group (slide 23).

Brehm, W. (2016, July 21). FreshEd #13 – Jane Kenway . Retrieved from http://www.freshedpodcast.com/tag/ethnography/ (EDXSymposium: New Frontiers in Comparative Education).

Jane Kenway is with the Australian Research Council and is an emeritus professor at Monash University in Melbourne, Australia. In this podcast, she explains “traditional’ forms of ethnography and multi-sited global ethnography, which are her area of specialization. She considers “traditional” ethnography to have three components: space, time, and mobility.

Insider/outsider stance is explained within the context of spatiality, community, and culture of space specific to ‘traditional” ethnography. Researchers are outsiders who are attempting to enter a space and become insiders, then leave the space once the research is completed. Research is conducted over an extended period of time in one place/space. As a result, researchers will get to know in an extremely intimate manner the ways of life of the community or group. “Work is supposed to be a temporality of slowness. In other words, you don’t rush around like a mad thing in a field, you just quietly and slowly immerse yourself in the field over this extended period of time and get to understand it, get to appreciate it bit by bit.” (minute 7:56).

“Traditional” ethnographers are not necessarily interested in mobility over time or exploring who enters and exits the site. Most ethnographers are only interested in the movement that occurs in the space that is being studied during the time that they are in the field. It is about looking at the roots of the space, not necessarily about looking at the movements into and out of the space.

Multi-sited global ethnography tries to look at the way bounded sites can be studied as unbounded and on the move, as opposed to staying still. It considers how certain things (e.g., things, ideas, people) are  followed as they move. The researcher moves between sites, studying change that is encountered in different sites. From this perspective, the interested lies in the connections between sites. Multiple sites with commonalities can also be studied at the onset, without the need to physically follow.

While this text is not solely about ethnographic case studies, it is rich with countless ideas for utilizing digital tools to aid in the multiple facets of qualitative research. In Chapter 5 of their text, entitled Generating Data, the authors dedicate a section to exploring Internet archives and multimedia data. They state that, “in addition to online communities, the Internet is rich with multimedia data such as professionally curated archives, ameteur-created YouTube and Vimeo videos and photo-sharing sites” (p. 81). They provide three specific examples, each explained below: The Internet Archive, CADENSA, and Britain’s BBC Archives.

The Internet Archive ( https://archive.org ) is a non-profit library of millions of free books, movies, software, music, websites, and more. The site also contains a variety of cultural artifacts that are easily available and downloadable. CADENSA ( http://cadensa.bl.uk ) is an online archive of the British Library Sound and Moving Image Catalogue. And finally, the BBC Archives ( http://www.bbc.co.uk/archive/ ) is a particularly useful site for researchers interested in reviewing documentary film and political speeches.

Wang, T. (2016, September). Tricia Wang: The human insights missing from big data. [Video file]. Retrieved from  https://www.ted.com/talks/tricia_wang_the_human_insights_missing_from_big_data

In this TED Talk, Tricia Wang discusses her ethnographic work with technology and advocates for the need to save a place for thick data as opposed to relying only on big data. She argues that while companies invest millions of dollars in generating big data because they assume it will efficiently provide all the answers, it routinely does not provide a good return on investment. Instead, companies are left without answers to the questions about consumer preferences and behaviors, which leaves them unprepared for market changes.

In turn, Wang coins the term thick data, which is described as “precious data from humans, like stories, emotions, and interactions that cannot be quantified” (Minute 11:50). Wang suggests that this thick data may only come from a small group of individuals, but it is an essential component that can provide insights that are different and valuable. As an example, while working for Nokia, her ethnographic experiences in China provided her with new understandings on the future demand for smartphones. However, her employer did not take her findings seriously, and as a result, they lost their foothold in the technology market. She posits that a blended approach to collecting and analyzing data (i.e. combining or integrating thick data analysis with big data analysis) allows for a better grasp on the whole picture and making informed decisions.

Her conclusions for a blended approach to data collection also have implications for blending ethnographic and case-study approaches. While Wang took more of an ethnographic approach to her research, one could envision what her work might have looked like if she had used an Ethnographic Case Study approach. Wang could have clearly defined the time and space boundaries of her various ethnographic experiences (e.g. as a street vendor, living in the slums, hanging out in internet cafés). This would have allowed her to infer causality through the generation of thick data with a small sample size for each location and bound by each group.

10 Additional Qualitative Approaches: Ethnography, Grounded Theory, Narrative, and Phenomenology

• Published: February 2023
• Cite Icon Cite
• Permissions Icon Permissions

This chapter introduces four approaches to inquiry—grounded theory, narrative, phenomenology, and ethnography—that, together with case study, comprise five primary qualitative research designs. The purpose of grounded theory is to develop a unified theoretical explanation for a process, action, or interaction. The theory is “grounded” in data generated with participants who have experienced that process, as opposed to being adopted from existing literature. “Stories lived and told” are the focal point of narrative inquiry. Inquirers elicit, interpret, and report detailed stories of individuals’ life experiences in order to illuminate phenomena or raise questions for readers’ consideration. In phenomenological research, the study’s central phenomenon will be some kind of human experience, such as grief or enjoyment. Analysis focuses on identifying the essence of that phenomenon for individuals who have experienced it. In ethnography, the researcher describes and interprets the shared and learned patterns of a culture-sharing group. The product of inquiry is a rich, complex description of the culture-sharing group at the heart of the study. Exemplar studies drawn from music education illustrate the common types and key features of each design.

For a case study on a specific topic, legal archaeology and the case study approach are highly recommended methodologies. Legal archaeology, as a micro-level case study research method, delves into the socio-historical context of a case using original sources to construct a detailed narrative, emphasizing the uniqueness and subjective nature of cases . On the other hand, the case study approach allows for a holistic understanding of a bounded system within real-life contexts, making it ideal for research that seeks to answer "how" and "why" questions . Additionally, case studies in health research have shown to contribute significantly to understanding causal relationships, providing evidence on system actors' theories of causality, causal mechanisms, and conditions under which these mechanisms operate, enhancing the overall evidence base for public health interventions .

Ethnography differs from traditional qualitative research in its emphasis on participant observation, cultural relativism, and the integration of insider and outsider perspectives . While traditional qualitative research may rely more on interviews and surveys, ethnography involves prolonged fieldwork where researchers immerse themselves in the lives of the subjects to gain a deep understanding of their practices and behaviors . Additionally, ethnography places a strong focus on reflexivity, acknowledging the researcher's positionality and continuous self-reflection throughout the study process . Furthermore, ethnography allows for the exploration of complex activities within specific contexts, such as translation and interpreting practices, through specialized forms like cognitive ethnography and microethnography . This methodological approach provides a holistic and in-depth understanding of cultural groups and phenomena, setting it apart from more traditional qualitative research methods.

Ethnography is crucial due to its ability to capture social forms effectively . It offers a detailed understanding of implementation processes by focusing on the social milieu of change . Despite its strengths, ethnography may not always be the recommended approach due to contextual weaknesses . This method examines routine interactions, providing rich descriptions and interpretations of social activities . Ethnography involves immersive fieldwork and detailed writing, making it both a method and an approach to understanding human behavior . Through participant observation and reflexivity, ethnographers can delve into the symbolism of cultures, organizations, and interactions, offering unique insights into various societal aspects.

Both phenomenological and ethnographic study designs offer valuable contributions to research. Phenomenology focuses on understanding individuals' lived experiences, while ethnography delves into cultural dynamics and social interactions. Phenomenography, a methodology closely related to phenomenology, aims to explore variations in how people experience a particular phenomenon. Additionally, combining narrative inquiry and hermeneutic phenomenological inquiry can provide a comprehensive understanding of complex phenomena like professional identity development. In the context of first responders assisting accident victims, interpretive phenomenological analysis revealed themes of helping victims and hoping for cooperation with the healthcare system. Therefore, the choice between phenomenological and ethnographic study designs depends on the research objectives and the depth of understanding required regarding individual experiences or cultural contexts.

Case studies are important in post qualitative comparative analysis studies because they allow researchers to explore and understand the impact of policy and practice in various fields, including education . Comparative case studies are particularly effective as they can synthesize information across time and space, providing a comprehensive understanding of the subject matter . These studies also help in formulating or assessing generalizations that extend across multiple cases, allowing researchers to identify similarities and differences among cases and analyze them against concepts and hypotheses . Comparative case studies offer opportunities to identify the role played by national and local factors in shaping practices and outcomes, such as attitudes to management and workplace performance . Additionally, the integration of qualitative and quantitative analysis in comparative case studies can strengthen the findings by providing systematic and replicable measures of uncertainty and influence . Overall, case studies provide a valuable tool for combining empirical data with theory and concepts, enhancing our understanding of complex phenomena .

Home-based psychotherapies have shown significant utility for seniors, particularly those with long-term care needs, depression, and cognitive impairments. Research indicates that older adults are generally open to using video-to-home (VTH) treatments, although they face unique barriers such as access to technology and physical and cognitive limitations . Psychotherapists delivering at-home cognitive behavioral therapy (CBT) to older adults have reported experiencing dilemmas related to balancing change and limitations, providing help while maintaining boundaries, and managing the dual roles of guest and host during sessions. These challenges, however, have led to professional growth and improved therapeutic techniques . The Homebound Elderly People Psychotherapeutic Intervention (HEPPI) study protocol aims to address these issues by offering a structured, home-delivered cognitive-emotional intervention for homebound older adults with mild cognitive impairment and symptoms of depression and anxiety. This approach is expected to improve episodic memory, general cognition, quality of life, and reduce loneliness . Meta-analyses of home-based interventions further support their effectiveness, showing significant improvements in social connectedness, reductions in loneliness, and alleviation of depressive symptoms. Interventions lasting more than three months and delivered through mixed platforms (both professional and volunteer-led) were particularly effective . Overall, while there are challenges, home-based psychotherapies provide a valuable means of delivering mental health care to older adults, enhancing their mental health and quality of life. Future research should continue to refine these interventions and explore their application in diverse settings to confirm and expand upon these findings.

Children understand museum collections through interactive experiences that involve sensory engagement, mark-making, and dialogue with objects, spaces, and people within the museum . Research emphasizes the importance of children's participation, visibility, and belonging in cultural institutions, such as art museums, to support their development as cultural citizens . Studies show that young children's learning in museums can be enhanced through well-theorized curatorial practices that focus on connecting children's learning with art museum practices . By providing opportunities for children to interact with rare artifacts, engage with materials, and experience the museum environment, museums facilitate children's symbolic meaning-making practices and participation in complex aesthetic experiences, fostering their understanding and appreciation of museum collections .

Organisational psychologists can implement various strategies for stress management, as highlighted in the research papers. These strategies include promoting employee involvement, recognition, work-life balance, health and safety practices, and growth and development opportunities . Additionally, it is essential to assess stress levels using psychological methods like questionnaires and physiological measures such as blood pressure and hormonal levels . Delegating work, sharing burdens with colleagues, taking time off for family, and reducing overtime are effective stress management techniques . Furthermore, implementing stress risk assessments based on management standards and providing management training can aid in reducing work-related stress and improving psychological well-being . By combining these approaches, organisational psychologists can create a comprehensive framework tailored to the unique needs of organizations, departments, and employees, leading to more effective stress management and positive outcomes .

Peer debriefing plays a crucial role in enhancing the trustworthiness of qualitative research studies by providing researchers with a platform to critically review their research design, data collection process, and data analysis with impartial colleagues, ensuring the accuracy and completeness of the study . This process aids in addressing the subjectivity inherent in qualitative research, where researchers act as instruments, influencing data collection and analysis with their unique perspectives and characteristics . Through peer debriefing, researchers can receive feedback on their methodological activities, leading to an external check on the inquiry process and ultimately enhancing the credibility and validity of the study . Additionally, peer debriefing offers emotional support to researchers, particularly in sensitive studies, contributing to study rigor and providing valuable insights that can lead to a deeper understanding of the phenomenon under study .

Utilizing games in learning integer operations has shown various positive impacts on students' understanding and engagement. Traditional games like kempreng and Si Goal and Si Patte' have been found to contain integer counting operations, making them effective tools for teaching mathematical concepts to elementary school children .
