Other Analysis Methods Georgia me u ce Techt 3 H gy Other Methods Overview Review of purpose of Analysis Review of Grounded Theory Other Approaches Content analysis Hermeneutics Narrative Conversational Analysis CA Ethnomethodology Georgia me u ee TechtmogtH ltgjy Analysis Review of Objective Fieldwork produces Voluminous raw data 0 Analysis turns this raw data into ndings Search for patterns in data Ideas that help explain why those patterns are there 0 Analysis process Organise eldnotes into readable narrative descriptions Major themescategories identi ed Illustrative case studies provide Georgia me u ce Techt 3 D gy Analysis Review of Grounded Theory 0 Analysis is process of hypothesis generation Grounded Theory Induction from the data through open coding Migration towards deductive analysis in con rmatory phases of study Georgia me u ee TechLmH ltgjy Analysis Other Approaches Overview Grounded Theory Just one of many approaches Other Approaches include Content analysis Hermeneutics Narrative Conversation Analysis CA Ethnomethodology Georgia me u ce Techt 3 D gy Other Approaches Content Analysis Content Analysis Testing a known hypotheses in a data set Create a set of codes that represent hypothesis to be tested Apply the codes to the current data set Analyse Largely deductive 0 Example Margolis 84 Does Ladies Home Journal present ads with servants or housewives in them Code adverts from 889 through I980 Each advert for the present of servant or housewife or neither Georgia me u ee TechLmH ltgjy Other Approaches Hermeneutics Hermeneutics Continuous interpretation of texts Eg constitutional law In US you assume that writers of Constitution had things in mind when they wrote it Task is to interpret and extract the meaning in light of current circumstances Hermeneutic circle We recognise and generalise a viewpoint through seeing instances of it But can only understand a particular act or artefact with reference to the worldview We re all doing hermeneutics all the time according to this view Hermeneutic Analysis The search for meanings and their inteconnection in the expression of culture Requires deep understanding of the culture and the meaning of its symbols Georgia me u ce Techt 3 D gy Other Approaches Narrative and Performance 0 Narrative analysis Discover the regularities in how people tell stories or give speeches Study of timings pausings intonations used Give text its meaning in speech Think of rising tone at end of sentence that means its a question Even when it might not be phrased as a question Georgia tme u ee TechmogtH ltgjy Other Approaches AestheticVisual Relatively new domains for Computer Science Information ArtVisual Communications Aesthetics Study of art and artistic appreciation To what extent is our experience of art similardifferent to our experience of nature Sociology of Art Study of the production and consumption Visual Sociology The study of images also the production of images Georgia me u ce Techt 3 D gy 9 Analys I 5 Common Features Georgia me u ee TecernogtH ltgjy Common Features Overview 0 Memos Diagramming Organisation Georgia me u ce Techt 3 D gy Common Features Memos 0 Variety of analysis rely on memos Memos Organise the analyst s thoughts For example contain a synthesis of a category discovered in Grounded Theory Document analyst s procedures For example explain the coding scheme used how developed what codes mean Qualitative analysis of qualitative data Is all about writing Georgia tme u ee TechtmogtH ltgjy Common Features Diagramming Memos sometimes not most effective method Eg drawing relations among various categories Diagramming Flow charts conceptual maps In other words familiar tools that support qualitative research Flow charts Document the sequence or flow of actions Conceptual maps Document how categories t together The key to diagramming Apply common sense Georgia me u ce Techt 3 D gy Common Features Organisation Organisation Online and offline there s a signi cant volume of paper Hard to organise During analysis it is dif cult to know what goes together which makes ling challenging 0 Tips things that have worked for me Book a conference room for a few days and tell the cleaners not to clean Spread everything out and le nothing keep moving it all around Different types of things for different types of notes Cards for notes MSWord for memos Sketchpad for diagrams Georgia tme u ee TechmogtH ltgjy Methods in CS Conversation Analysis Ethnomethodology Georgia me u ce Techt 3 D gy Conversation Analysis amp Ethnomethodology Two widely used qualitativesociological techniques HCI cscw 0 More than just analysis Rely on methods we ve explored but have speci c data collection needs Analysis focused on particular concerns 0 Both techniques Emerge from phenomenology and Goffman s sociological perspectives Both focused on understanding everday action and interaction From the perspective of those engaged in it Georgia me u ee TechtmogtH ltgjy Conversation Analysis Overview Conversation analysis The study of everyday conversation And how people maintain an interaction order Purpose to understand social order of talk What does the order of conversation do what s said How do people collaboratively nish conversations Face to face we use utterances and body posture to close a conversation How many times have you been on the telephone trying to end the conversation and the other person doesn t seem to get it How do you close a conversation in email or IM Georgia me u ce Techt 3 D gy Conversation Analysis Unique Aspects Incredibly detailed transcripts of conversation Include not just what was said but Pause timings intonation organisation so that overlaps can be seen Data sessions Joint analysis of a small sample of data Not exclusive to CA but enthusiastically embraced in this tradition Belief that analysis is stronger when people agree about what s happening Georgia tme u ee TechmogtH ltgjy Conversation Analysis Computing 0 Electronic communications Often disrupt the social order of interaction Apply Conversation Analysis to nd out why Hutchby studies of IRC 0 Designing new types of communication technology Examine CA literature for examples of good interaction order Apply them to the design of new technologies Aoki andWoodruff Georgia me u ce Techt 3 D gy Ethnomethodology Overview Ethnomethology Ethno Folk so folk methodology 0 What does that mean Everyday people socially reason about a variety of things Draw on evidence use methods to make sense of situations Ad hoc practices dealing with vagueness etc rules making do wait and see enough is enough glossing let it pass These types of practices help us all manage our actions and interactions With each other and with technology Georgia tme u ee TechmogtH ltgjy 20 Ethnomethodologists Computer Supported Cooperative Work CSCW Ethnomethodologists enter the eld Looking for the practices that help people function 0 Ethnomethodologists in CSCW Graham ButtonJohn HughesWes Sharrock All participated in understanding how technology and people s everyday practices interact Support work of design By explaining what it is that people really do and how that could be best supported Georgia me u ce Techt 3 D gy 21 CA and Ethnomethodology Final Words 0 CA and Ethnomethodology are Pervasive throughout the social sciences in computer science But do not represent all possibilities Most of all they represent very particular stances On what the purpose of studying social settings is Georgia me u ee TechLmH ltgjy 22
