Estudos de caso em educa？？o. Investiga？？o em profundidade com recursos reduzidos e outro modo de generaliza？？o

investigators with scarce resources and even alone, but challenging their research qualities, they can give a serious contribution for the investigation, through a case study, in alternative to studies of vaster perspective but demanding more resources in material and in persons. and that study obviously can be continued later on with future works of the own or of other investigators. the following reflection is based on several authors with major incidence in works of stake (1995; 1998) and yin (1994; 2005), it tries to delineate the procedures to use in the adoption of the case study in education problems and it includes, in complement, the key-ideas of some case studies about education inventoried by yin (2005).
