Três abordagens do método de estudo de caso em educação: Yin, Merriam e Stake

Abstract

O estudo de caso tem sido um terreno contestado na investigação em ciências sociais porque utiliza abordagens diferentes, às vezes opostas. É uma das mais utilizadas metodologias de investigação qualitativa em pesquisa educacional. Contudo, os metodólogos não fazem consenso sobre a concepção e a realização desse método, dificultando a sua plena evolução. Este autor concentra sua atenção nas obras de três deles, Robert Yin, Sharan Merriam e Robert Stake, buscando captar perspectivas divergentes, convergentes e complementares. Desse modo, busca contribuir com pesquisadores iniciantes no âmbito da educação, apresentando técnicas e estratégias para, assim, poderem combinar perspectivas e atingir propósitos de investigação

“…This study uses qualitative research methods with a case study approach. Bazan [18] stated that qualitative case study research provides a strong understanding of the phenomena that arise from the complexity associated with interpersonal activities in a broad social context. A case study can provide a rich collection of data so that researchers can directly observe and conduct interviews with informants related to the phenomenon [19]; [20]; [21].…”

“…This work adopted the case study research methodology following Yin's perspective which sees it as "an empirical investigation that investigates a contemporary phenomenon within its real-life context, especially when the boundaries with the context are not clearly defined, or the investigator has little control over these points" [14].…”

“…Cruz et al defined the first two steps for our specific problem as part of their case study protocol [4]. The Research Design contains: Research questions that provide an important key, establishing the most relevant research strategy to be used; Propositions, which direct attention to what should be examined within the study objective; units of analysis, which relate the data with the fundamental problem, linking them to propositions; and finally, the definition of a criterion for the interpretation of the results obtained [14], [15]. We applied this protocol to a scenario developed in OpenSimulator, using its research questions (as well as its propositions and units of analysis):…”

“…The analysis of results was accomplished according to the general analytical strategy defined by Yin [14]. That is, linking the collected data to the stated propositions, thus creating one or several chains of evidence for each proposition.…”

“…In fact, the continuous and recursive observation of the action in the same classroom is configured as 'a phenomenon … occurring in a bounded context' (Merriam, 1998, p. 27), for which it is possible to perform an intensive and holistic analysis (Yazan, 2015).…”
