ABSTRACT

A Teoria de Resposta ao Item (TRI) tem sido considerada por muitos especialistas como um marco para a Psicometria moderna. A TRI é um conjunto de modelos matemáticos que considera o item como unidade básica de análise e procura representar a probabilidade de um examinando dar uma certa resposta a um item como função dos pârametros do item e do(s) traço(s) latente(s) do indivíduo. No presente artigo objetivou-se discutir os pressupostos, modelos e aplicações da TRI em avaliações educacionais de larga escala. Também são feitas algumas considerações sobre a utilização do software Bolog-MG 3.0. Diante da complexidade do tema tratado, não se teve a intenção de esgotá-lo, e sim, oferecer aos pesquisadores e avaliadores educacionais diretrizes para a tomada de decisões no momento de operacionalização de análises psicométricas por meio da TRI.


Item response theory(IRT) is considered as a landmark of modern psychometrics by a great number of specialists. IRT is a set mathematical models that considers the item like the basic unit of analysis and that relates the probability of a correct response of an examinee on an item in function of the item parameters and underlying latent trait of the evaluated person. This current paper aims to discuss the assumptions of IRT, the various models and applications in large scale educational assessment. Also, the utilization of the software program Bilog-MG is commented. Taking the complexity of the exposed topic into consideration, we do not intend to exhaust it, but are trying to offer support to researchers when making decisions in the process of performing psychometric analyses using IRT.

ABSTRACT

For decades, coping has undergone intensive investigation through different theoretical lens. In this paper, three theoretical standings in coping research were proposed:namely,the process theory, the trait theory and the situation theory. Relevant research and measurements were introduced. In the end, different perspectives were reevaluated and implication for further research was discussed.
