Neo-ethnographic’ an in-depth investigation of a single case by a participant observer
Evaluative’. ‘a single case or group of cases studied at such depth as the evaluation of policy or practice will allow (usually condensed field work)’.
Multi-site case study, which consists of ‘condensed field work undertaken by a team of workers on a number of sites and possibly offering an alternative approach to research to that based on sampling and statistical inference’
Explanatory (testing theories) examine the data closely both at a surface and deep level in order to explain the phenomena in the data.
Exploratory (as a pilot to other studies or research questions) set to explore any phenomenon in the data which serves as a point of interest to the researcher.
Descriptive (providing narrative accounts) set to describe the natural phenomena which occur within the data in question, for instance, what different strategies are used by a reader and how the reader use them. The goal set by the researcher is to describe the data as they occur.
The intrinsic case study: the interest is in the case for its own sake, based on uniqueness. A researcher examines the case for its own sake.
The instrumental casestudy, selected to help in the understanding of something else, based on issues. the researcher selects a small group of subjects in order to examine a certain pattern of behavior.
The collective case study, groups of individual studies that are undertaken to gain a fuller picture, more than one case studied. The researcher coordinates data from several different sources, such as schools or individuals.
