ab: Summary: This paper aims to present the possible contributions of
anthropological theory of didactics in a priori analysis of the
didactic sequence The random walks of Monica. This sequence addresses
elementary concepts of probability theory for basic education, and has
undergone improvements based on the recommendations of the national
curricular parameters, favoring active participation of the subjects,
who constantly interact with the tasks and are challenged to make
decisions regarding each result. Analysis revealed that this sequence
makes it possible to highlight a complete praxeological organization
(task/technique/technology/theory) and reverses the usual praxeology,
because it starts with a problem situation, from which emerge the
intuitive conceptions of probability, the frequentist probability,
resulting from random experimentation, and the theoretical probability
(Laplace) calculated from the mathematical modeling, using the diagram
of possibilities.
