CUEVAS, Humberto  e  RAMIREZ, Greivin. Performance in Stochastic between Secondary School Teachers: An Exploratory Study in Two Regions of Costa Rica and Mexico. Educ. mat. [online]. 2018, vol.30, n.1, pp.93-132.  Epub 07-Jan-2022. ISSN 2448-8089.  https://doi.org/10.24844/em3001.04.

The results of an exploratory study on the performance in elementary stochastic variables of 111 secondary school teachers from Mexico and Costa Rica are shown. An instrument of 16 items was developed and validated according to the guidelines of the Program for International Student Assessment (PISA). The findings indicate that the performance is not sufficient to comply with the stochastic educational standards established in study programs. It was determined that more than half of teachers (59) do not know basic probability principles, 68 have difficulties interpreting grouped data in graphs and tables, 68 do not classify variables accurately, and there are also difficulties differentiating between random and deterministic phenomena (19). It is inferred that in most of the topics the disciplinary domain was similar in both countries, showing differences in favor of the Costa Ricans in variable classification and in favor of the Mexicans in event independence. It is recommended that institutions consider in their programs the historical development of probability and statistics, use the discipline’s language, and analyze information in different representations, as well as solve problems inside and outside the school environment.
