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.

Data collection procedures

Obviously, I’m working on Case Study approach in which participants should be involove in a program: SIOP or CLIL. Regarding the data collection circle, I should start from "Locating stie / individual" in my data collection procedure.

☞ First, my data collection site would be my workplace, although it can raise issues of power imbalance between me as a research and my students as participants. At least, I’m not their homeroom teacher, who is mostly taking care of them and has more authority. And the case would be class 5, who consented to be involved in my project the most by over 60%.
☞ I don’t believe that I have any problem to gaining access and making rapport, which I already have. But still I should get formal access with consent form provided on p.123.

- The right of participants to voluntarily withdraw from the study at any time
(not seems to be included – Is it ok?)
- the central purpose of the study and the procedures to be used in data collection
- comments about protecting the confidentiality of the respondents
- a statement about known risks associated with participation in the study
- the expected benefits to accrue to the participants in the study.
- the signature of the participant as well as the researcher

I already met gatekeeper, the homeroom teacher, and explained the purpose and brief plan.

☞ For sampling, my plan is below.
event : SIOP or CLIL with science
setting : 30 students in mixed level
actors : class 5 students
artifacts : improved positive attitude and confidence in both subjects
              Improved test score in both subjects.
Site level : in both language room and classroom
Process level: teaching science in English by 10 min in both English and science classes
participants level : mixed level in English and science ( Should check the diagnosis test result)

How to use the sampling strategies? Am I using any?

☞ As forms of data, I should address interview, observation, audiovisual materials
     (does it mean by teaching materials?), journaling (actually making comments online)like daily log, solving quizzes, photo elicitation on certain topic.

The bold types are my questions…
