Analysis of the use of Bayesian reasoning in elementary school students

Several investigations on the teaching of probability has been determined that it is difficult for people who have made the focus on the uncertainty and in turn encourage the ability to interpret, communicate and evaluate probabilistic situations, this occurs because the population is educated. under the deterministic logic, which is that the individual always expect the same result, and this is predictable, or bivalent, ie corresponding to answer yes or no. We present a gaze focused work on the analysis of Bayesian reasoning not like the fact of using algorithms, but as the decision-making under uncertainty for primary school students.
