Análisis de la incertidumbre en la medición del nivel cognitivo usando Lógica Difusa. Rev. iberoam. tecnol. educ. educ. tecnol. [online]. 2022, n.33, pp.43-53.

The aim of the present article is to develop an approach on the uncertainty treatment in the cognitive state measurement. This uncertainty originates in the evaluator's subjective assessment of the student, which is subject to their experience and sensitivity. Therefore, Fuzzy Logic is used as the basis diagnostic model design. In the proposed model, elements that add relevant information to the evaluation have been identified if it is compared to the one carried out with traditional methods. Those elements are as follows:

Linguistic variables that add information about the individual effort in learning throughout an academic period, providing information about their final performance level. An individual profile is obtained.

Cognitive levels based on Bloom`s revised taxonomy. From those levels, group profiles are obtained. Moreover, the total uncertainty from each group of students has been measured.

An example model is presented in which the observed values are compared to those inferred by the system. In addition, the model's performance values are presented.

Keywords : Uncertainty; Cognitive level; Fuzzy logic.
