The purpose The purpose …of this case study (strategy of inquiry) will be to

_________________(understand? describe? develop? discover?) the _______________(central phenomenon being studied) for ________________ (the participants, such as the individual, groups, organization) at ________________(research site). At this stage in the research, ___________________(central phenomenon being studied) will be generally defined as _______________________(provide a general definition).

Practice CodingPractice Coding We will begin coding by practicing We will begin coding by practicing

with at least one of the sources of with at least one of the sources of data you have collected for your field data you have collected for your field project (e.g., interview transcript or project (e.g., interview transcript or observation write-up with analytical observation write-up with analytical memo)memo)

Making Sense of Your Field Research Data Analysis with Research Groups: Step 1

Step 1: Work independently. Read observation field notes, interview transcripts and document summary forms. What are you learning from the data? Look for emerging insights, themes and patterns in data. How is the data helping to answer your research questions? What are you finding? What part, if any, do role groups or programs play in your study? Read everything again.

Page 22: Research  Design  Part  I I Updated  Summer 0

Data Analysis with Research Groups: Step 2

Step 2: Convene group. Research groups meet to discuss the data. Each group member must report what he or she is finding in data gathered (see step 1). After each member has presented, the group will consider how the themes are similar or different depending on data source. Group must generate and agree on a tentative list of themes or codes. If the group still has a lot more data to collect, approach the codes as very tentative and finalize later in week, perhaps in a virtual meeting. Everyone needs a copy of the code list.

Page 23: Research  Design  Part  I I Updated  Summer 0

Data Analysis with Research Groups: Step 3

Step 3: Work independently. Next step will be to code all data gathered using the agreed upon coding scheme (code list).

To do the actual coding, the group may decide to use atlas.ti software. Alternatively, groups may want to bring colored markers and post-its to class for hands-on coding, or coding can be done electronically with a word processing program.

Page 24: Research  Design  Part  I I Updated  Summer 0

Data Analysis with Research Groups: Step 4

Step 4: Convene group. Next the group will reconvene to discuss how individual coding was similar or different, and decide what is best representation of the data. Once that is set, carefully examine again all the data and themes. It is at this stage that you will look for patterns and move from themes and codes to findings.

FindingsFindings

Now that all the data have been coded, how do the data triangulate? What are the findings? Debate alternative interpretations. How will you address unique cases or outliers? Determine the story that your study must tell.

ConclusionsConclusions Based on the findings, what do you

conclude? How does your study inform the

guiding research questions? How does your study add to our

knowledge or understanding of education?
