BORTOLOTTI, Silvana Ligia Vincenzi y ANDRADE, Dalton Francisco De. Aplicação de um Modelo de Desdobramento Graduado Generalizado - GGUM da Teoria da Resposta ao Item. Est. Aval. Educ. [online]. 2007, vol.18, n.37, pp.157-188. ISSN 0103-6831.
Evaluation as a measurement instrument plays an important role in the organizations focused on the growing demands of the current world. Item Response Theory (IRT) provides models for evaluation. IRT is constituted of a set of models that represent the relationship between an individual's probability to give a certain response to an item, the characteristics of the items and their latent trait(s), as defined by the study. The purpose of this article is to introduce the GGUM - Generalized Graded Unfolding Model of IRT for satisfaction measurement. This model analyzes binary and graded responses based on a proximity relationship. The adequacy of the GGUM will be shown through an application to evaluate the satisfaction of undergraduate Technology students at the Federal Technological University of Paraná, at the Medianeira campus, Paraná, regarding the course they attend. The results obtained in the application illustrate the great potential of this model.
