validation and evaluation

In qualitative study, these two could be the basis of the research result. Because it's qualitative..., which means the research might be too subjective.

For validation, eight strategies are mentioned on the book.

 - prolonged engagementand persistent observation
 - triangulation (corroborating evidence from different sources)
 - peer review or debriefing (devil's advocate - 고의적인 반문: 논문 디펜스처럼..?)
 - negative case analysis
 - clarifying researcher bias from the outset of the study
 - member checking
 - rich and thick description
 - external audits

especially, triangulation and peer review or member checking are easily conducted and time and cost effective procedures..


Also intercorder agreement is needed to get reliability.

Finally, criteria for case study...
I chose below as several priority checklist...

 - does the report have a conceptual structure? 
 - is the case adequately defined?
 - is the reader provided some vicarious experience?

Phenomenological study and ethnography

Phenomenological study, ethnography looks similar in data collection and its analysis. Although the boundary for study is quite different.

For ethnoghraphy, the researcher mostly should be inner member of the research group to observe closely. According to the characteristics, the result is also stated by the researcher in many of the sample societies. So it might be biased or vague depending on the observer's view. And it could establish validity through prior and ongoing study on the similar society.

For phenomenological study, the general procedure is not much different from it of case study. Through interview, observation and drawing with the participants, the researcher is able to get certain image of the topic. And based on collected data, the researcher categorized them into a range of items.
Again, like case study, it established validity through collecting much data as possible, and verification should be conducted as well.

For both of qualitative researches, the idea that researcher must have fun doing researches was in my mind. Generally that's the merit of qualitative research, which is good for myself.
