The Ministerio de Educaci´on Nacional de Colombia (MEN), is increasingly concerned about the continuous improvement on teaching processes of the foreign languages teachers and has commissioned the assessment of this process to the Instituto Colombiano para la Evaluaci´on de la Educaci´on (Icfes), in order to assess the knowledge of those teachers and ensure that they conforms to the quality standards of the Common European Framework of Reference for Languages (CEFR). The reduction of the estimation errors results as a key objective in the rating process of the tests That are Implemented by the Icfes, in order to improve increase accuracy for Evaluating parameters: such as the difficulty of the test and the performance of Those Who present the test. In a brief comparison este documento Between classical and Bayesian methodology for Rasch model is provided, esta comparison contains the behavior and upkeep of the classic assumptions for the second methodology. Furthermore the reduction of the errors for the Ability and difficulty parameters in the Bayesian framework is presented. |
