Exploring Interdisciplinarity in Project-Based Learning: Choosing the Research Theme

This article discusses interdisciplinarity in the teaching of statistics through Project-Based Learning. We share the discussion that arose after publication of the Common National Curriculum Base in 2018, which suggests the inclusion of projects whose level of complexity and broadness increases gradually throughout basic education (from six to seventeen years old). Our goal is to highlight the initial moment that is paramount to the success of this approach: the selection of the theme to be investigated. We describe a qualitative research study that analyses official documents, recent studies in the area, and recordings of the sessions in which teachers and students discuss the theme to be chosen before presenting a few considerations that may contribute to promoting statistics literacy.
