Ontosemiotic analysis of tasks involving statistical graphics in Mexican Primary Education textbooks

co The purpose of this research is to analyze the intended meaning of tasks involving statistical graphs in mathematics textbooks of Primary Education in Mexico. For this purpose, theoretical and meth-odological elements of the Ontosemiotic Approach (OSA) are used, specifically, two analysis levels for mathematical activity: 1) phenomenological-anthropological and 2) ontosemiotic, which allow the study of the primary objects involved in the tasks. The results indicate that four types of problem situations are presented in the textbooks: 1) translating statistical tables into statistical graphs; 2) reading data in sta-tistical graphs; 3) reading within the data in statistical graphs; and 4) reading beyond the data in statistical graphs. This research contributes to the planning and task designing of pre-service and in-service teach-ers of Elementary Education for approaching statistical graphs.
