This work proposes an approach to teaching statistical topics in secondary technical education,
taking as reference the procedures adopted by mathematical modeling and inserted
in a investigation environment, contextualized and interdisciplinary. Previously, to make
feasible these relationships, it presents the definitions of the main statistical themes approached
by the mathematics curriculum component in secondary education, based on
the object of study. Then, in a synthetic way, it describes the ability and competences
designated by the National Curricular Parameters (NCP) for the teaching of statistics,
complemented by an analysis of the contents of textbooks, which demonstrate to be insufficient
in basic technical education. In this, find a research on mathematical modeling,
its history, concepts and processes. Also, contributions to the teaching of statistics, being
considered a methodological tool in the orientation and direction of teaching, through
the stages of interaction of the content approached, mathematization of the situation and
evaluation of the results. An application in the caipira broiler has been proposed, which
conducted to the analysis of two regression models to represent the relationship between
the variables involved, being: linear model and quadratic model. The evaluation of the
models allowed the choice of the most adequate regression, opting for the quadratic model
because it presented a higher coefficient of explanation (R-squared). The culmination of
the work reflects in the use of the “triple”: planning of actions, insertion of the contents
to the reality of the students and in the established association between the several
disciplines, as a tendency in the promotion of an effective learning.
