This text discusses three main types of qualitative research: document study, case study, and ethnography. The qualitative approach offers three main ways to conduct research: document study, case study, and ethnography. Qualitative research is used to understand human phenomena and their complex social relationships in various contexts. It involves analyzing phenomena within their context, considering multiple perspectives, and collecting various types of data to understand the dynamics of the phenomenon. Document study involves analyzing written materials, statistics, and iconographic elements to understand a phenomenon. It is useful when studying people who are no longer alive or inaccessible due to distance. Documents are considered non-reactive sources of information, as the information remains the same over time. However, documents may not always be representative of the phenomenon being studied, and there may be biases in the information provided. Case study involves in-depth analysis of a specific unit, such as an individual, organization, or situation. It is used to understand how and why certain phenomena occur, especially when there is little control over the events being studied. Case studies can involve multiple subjects or institutions and often use a variety of data collection methods, including observation and interviews. Ethnography involves in-depth study of a culture or group, often through prolonged contact with the group. It aims to describe and interpret the meaning of events within the group's culture. Ethnography is holistic, considering the group's history, religion, politics, economy, and environment. It involves continuous interaction between data and theoretical explanations, and the researcher must remain open to new insights. The text highlights the importance of flexibility and creativity in qualitative research, as well as the need for careful data collection and analysis. It also emphasizes the role of interpretation in understanding the meaning behind data, and the importance of maintaining a clear research objective and relationship with the subjects being studied.This text discusses three main types of qualitative research: document study, case study, and ethnography.
