I’m working on a sociology question and need an explanation and answer to help me learn.

Ethnographers engage in participant observation in order to gain insight into cultural practices and phenomena. These insights develop over time and through repeated analysis of many aspects of our fieldsites.  This type of research often occurs over several months or years and is a significant investment for a scholar, both in the time in the field and the time outside the field.  With all that you’ve learned in the text and lesson this week, respond to the following questions.
Directions
In a word processing program, provide your best answer to the following questions.

1.   You are interested in how “gamers” or people who play video games professionally (i.e. for pay) see themselves and their social order. Which of the approaches discussed in Babbie/lesson would be best suited for the particular study?  Why?  What are the advantages and disadvantages of the approach?
2.   Where would you study gamers?  What kind of time commitment would you expect to make?  Would there be any particular challenges with gaining access to gamers or the gamers’ community?  How would you approach gaining the trust of the subjects?
3.   What researcher role would best suit the study?  How difficult do you expect it to be to maintain the role of the researcher, as opposed to just another member of the group?
4.   Would you reveal your identity as a researcher?  If so, when and how would you expect other members of the group to react?  If not, why not?
