my cafe for research opened

Please come see what I'm doing and leave comments. It couldn't be better.

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.

data collection design for case study

Data collection design

Documents : Although what it means by documents for research, according to my understanding, researcher should get consent by Ss. However, I’d like to inform Ss what I’m going to do differently in classes and ask their background knowledge and expectation. For specific lesson protocol, I’m considering SIOP model modified to Korean context. Also, prior researches would shed lights on research methodology. This is grounded theoretically.

 Ss’ responds to survey before the research starts.

 Books for SIOP model

 References

Archival records : Including pretest Ss will take a monthly test formally and informally, which show Ss’ achievement and effectiveness of the lesson. Also, I could record my lesson and reflect for myself to recognize the Ss’ reaction, effectiveness of materials.

 monthly evaluation score and progress

 Self reflection through video recording

Interviews : Interviews could show their emotional and physical response. Other teachers’ interview will support or supplement the process.

 Ss’ feeling about the class, self improvement, achievement

 Teachers’ interview after observation my lesson

 Co-teacher’s interview

Direct observation : No matter its subjectivity, the researcher could see Ss’ achievement and give corresponding feedback.

 in class observation, evaluation,

Participant-observation : peer pressure effect and it’s more affective than teacher’s

 gallery tour for their group project and make a comment or feedback / website comment

Physical artifacts : good evidence to its’ efficiency

 dramatize video clip?

Materials : good evidence to its’ efficiency

 mini book, drawing, group work, project artifacts, assignment

For validity, Pattern matching could be useful, but didn’t get what it is and how to do.

Case study

Case study is interesting, regarding its construction. This appendix F was conducted on a gunman case, but mostly narrates the reponses.

To conduct the research, it was limited by several factors which were in-campus groups only, context-dependent inquiry,  inductive data analysis, time period, and single case.

There were used a range of data collection, such as interview, observation, documents, and visual materials, and added informants' feedback on the researcher's statements and comments at the end.

To interpretate the data, the researcher categorized them into five themes. This helps readers understand the case study result(? or meaning of the case) better.
One thing I'd like to take a note is using similar prior case to have evidence of retrigerring. If there were not certain evidence for the case, I learned that it's acceptable to replace other similar incident. Am I right?

After discussing possible issues and limitation of the research, it can be written epilogue.

talk to gatekeeper the other day

C: 예랑이 반을 수업연구반으로 정하려고 해.
    Yerang, may I sample your class for my research?

Y: 아.. 우리 반? 무슨 연구인데
   Oh, my class? What kind of research for?

C: 과학, 영어 통합교육
   Sort of integrated teaching with science and english

Y: 어떻게 하면 되?
   So what am I supposed to do?
C: 현재까지 계획한 바로는... 과학 수업 중 10분 정도를 영어로 설명할 기회를 줘.
    Up to now, I'm planning to conduct english lesson for 10 mins at the end of the your science classes twice a week.
Y: 그럼 뭘 기대하는 거야?
   Then what do you expect to?

C: 과학., 영어 성적이 다 오를 수 있는지..
   To see if it's valuable for both subjects..

Y: 진도 나가기가 벅차서, 되도록이면, 진도 관련 내용으로 부탁해..
   Actually 6th graders are under big pressure of test, so hopefully it would be relevant to the lesson topic.

C: 엉. 그럴게. 그리고 자기가 직접 하는 거 아니어도 되고
   Oh, sure. And you don't have to do by yourself, either.
   때로는 나눠주고 읽게 하거나, 자료를 들려주면 되고
   Sometimes you could just distribute some readings, or playing audio materials..
  때로는 내가 직접 가서 설명을 할 것이고
  Or even I could go and explains some concep, too.
Y: 응.. 오케이~
   Ok, I see.
