    A categoria precisão na avaliação e na meta-avaliação: aspectos praticos e teóricos em um novo enfoque
    (2005) VELLASCO, Marley Maria Bernardes Rebuzzi; LETICHEVSKY, Ana Carolina; TANSCHEIT, Ricardo; SOUZA, Reinaldo Castro
    This article deals with the category precision of a true evaluation in the scope of evaluation and meta-evaluation (evaluation of evaluation). First, it presents the modern conceptualization of evaluation and meta-evaluation and then discusses the role of meta-evaluation to ensure the quality of an evaluation process, in its different approaches, from the four categories of a true evaluation (utility, viability, ethics and precision). The emphasis of the article is on the category precision: (1) its importance in a meta-evaluation, in all the phases or stages of an evaluation, with its advances and its limitations and; (2) its application in the meta-evaluation itself which, while an evaluative process, must also follow the four patterns of a true evaluation. In this sense, practical and theoretical aspects which merit attention in the negotiation, the design, the implementation and the conduction of a meta-evaluation are presented, when the paradigm of the treatment of the data of a meta-evaluation, through the classical logic and not the fuzzy logic, is discussed.

    Um sistema fuzzy de suporte à decisão para meta-avaliação uma nova abordagem e um estudo de caso desenvolvidos no Brasil
    (2007) LETICHEVSKY, Ana Carolina; VELASCO, Marley Maria Bernardes Rebuzzi; TANSCHEIT, Ricardo
    This paper presents a new methodology for meta-evaluation that makes use of fuzzy sets and fuzzy logic. It is composed of a data collection instrument and of a hierarchical fuzzy inference system. The advantages of the proposed methodology are: (i) the instrument, which allows intermediate answers; (ii) the inference process ability to adapt to specific needs; and (iii) transparency, through the use of linguistic rules that facilitate both the understanding and the discussion of the whole process. The rules are based on guidelines established by the Joint Committee on Standards for Educational Evaluation (1994) and also represent the view of experts. The system can provide support to evaluators that may lack experience in meta-evaluation. A case study is presented as a validation of the proposed methodology.
