Lecture 3 - qualitative research

QUALITATIVE RESEARCH
key words: study context, subjective findings, time- and context-dependent, inductive, experiences of people, "how" and "why" questions, naturalistic settings, purposefully selecting participants, study of invidual cases;

*triangulation - collection of data from many sources

Data sampling - purposive, extreme situations, maximize variation, or snowball, or random
Data analysis - data reduction, data display (tables, charts), conclusion
Validity - asses if the researcher is objective, if the results can be generalized beyond the research context, if research is repeteatable, scope of data, depth and richness of data
Reliability - if the same results would be made in different place or time, if the same observations would be made if the researcher had paid attention to different phenomena, eg. we can use two researches to gain that;

watch out for: holistic fallacy - tend to interpret data as more patterned and congruent that in real; elite bias - high-status informants overweight the data; going positive

Phenomenology - eg. study phenomenon from students' point of view
Constructivist - eg. how students themselves construct models of what the learn

MIXED RESEARCH
- use both qualitative and quantitative research methods;

Advantages: (lanie wodyyyyy)
+ overcome weakness of single method study
+ get more holistic picture
+ numbers can add precision
+ pictures add meaning to numbers
+ provides stronger evidence
