Algebraization Levels in the Study of Probability Burgos Navarro, María José Batanero Bernabéu, Carmen Díaz Godino, Juan Probability Formalization Fundamental stochastic ideas Algebraization levels This research was funded by Project PID2019-105601GB-I00/AEI/10.13039/501100011033 and Research Group FQM-126 (Junta de Andalucia). The paper aims to analyze how the different degrees of mathematical formalization can be worked in the study of probability at non-university educational levels. The model of algebraization levels for mathematical practices based on the onto-semiotic approach is applied to identify the different objects and processes involved in the resolution of a selection of probabilistic problems. As a result, we describe the possible progression from arithmetic and proto-algebraic levels of mathematical activity to higher levels of algebraization and formalization in the study of probability. The method of analysis developed can help to establish connections between intuitive/informal and progressively more formal approaches in the study of mathematics. 2022-02-24T07:44:09Z 2022-02-24T07:44:09Z 2021-12-27 info:eu-repo/semantics/article Burgos, M.; Batanero, C.; Godino, J.D.
