Medición de la Alfabetización Económica en Ni？os: Oportunidades Diagnósticas con el Modelo de Crédito Parcial

this paper describes the use of the partial credit model (pcm) to measure economic literacy in children, with ordered multiple-choice items (omc). we developed omc items based on a piagetian model that proposes three progressive levels in the development of concepts and reasoning about the economy. in omc format, each of the possible answer choices was linked to a cognitive stage of economical thinking proposed by the theory. the items were administered to 1035 children, ages 10 to 15 years, and calibrated using the pcm. the results show both the utility of omc items and the efficiency of pcm as tools for the score, analysis, and interpretation of diagnostic assessments constructed in a piagetian framework.
