Felipe Ruz, Elena Molina Portillo , José Miguel Contreras García

• In this work we present the process of design, construction and pilot implementation of an instrument to evaluate the knowledge about stochastic in mathematics teachers, in relation to Probability Content. These pilot tests were carried out in a sample of 127 future mathematics teachers, from Spain and Chile. The results are organized starting with some indicators on the psychometric properties of the items analysed and the overall results of the questionnaire. Subsequently, we jointly study the items that make up each category of knowledge of the content considered, between common or expanded, looking for differences between the groups that make up the sample. It is concluded that the instrument has acceptable characteristics, as well as the items analysed and its reformed application is projected in the future.
