Resumo: We present an exploratory study of solving probabilistic tasks proposed to a sample of 55 primary school 6th grade Costa Rican children on comparison of probabilities and the construction of the sample space, analysing their strategies and errors. Comparing the results with previous investigations, an improvement is observed in the item in which the comparison of favorable and possible cases can be applied, and where the comparison of areas is necessary; however, there were no differences in the item in which the order in which the favorable cases are located is introduced as a distractor. The sample space is generally correctly built in the cases of possible and equiprobable event, but not in those of impossible or certain events.

Comparando con investigaciones previas, se observa un mejor desempeño en el ítem en que se puede comparar casos favorables y posibles y en el que es necesaria la comparación de áreas, pero no hay diferencias en aquel en que se introduce como distractor el orden de colocación de los casos favorables. Se observa que, en general, se construye correctamente el espacio muestral en los casos de suceso posible y equiprobable, no así en los de sucesos imposible o seguro.FACED - UFRGS2022-02-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionhttps://seer.ufrgs.br/index.php/educacaoerealidade/article/view/105401Educação & Realidade [Education & Reality]; Vol. 46 No. 3 (2021)Educação & Realidade; v. 46 n. 3 (2021)2175-62360100-3143reponame:Educação & Realidadeinstname:Universidade Federal do Rio Grande do Sul (UFRGS)instacron:UFRGSporenghttps://seer.ufrgs.br/index.php/educacaoerealidade/article/view/105401/66297https://seer.ufrgs.br/index.php/educacaoerealidade/article/view/105401/66298Copyright (c) 2021 Educação & Realidadeinfo:eu-repo/semantics/openAccessHernández Solís, Luis ArmandoBatanero, CarmenGea, María MagdalenaÁlvarez-Arroyo, Rocío2022-03-21T22:22:16Zoai:seer.ufrgs.br:article/105401Revistahttps://seer.ufrgs.br/educacaoerealidadePUBhttps://seer.ufrgs.br/educacaoerealidade/oai||educreal@ufrgs.br2175-62360100-3143opendoar:2022-03-21T22:22:16Educação & Realidade - Universidade Federal do Rio Grande do Sul (UFRGS)false
