Abstract

The objective of this work was to identify the language used by students in the ninth year of Elementary School regarding the notion of the word “Uncertainty”, based on their everyday knowledge and/or what they learned at school. Consequently, the analyzes obtained will be part of the development of activities that will compose a paradidactic book to support the teaching of probabilistic content. Thus, the following research question was established for this study: How will the identification of probabilistic language contribute to conducting the teaching and learning process of probability in the ninth year of Elementary School? This research was exploratory, with a qualitative and quantitative approach using a questionnaire made available on Google Forms and analyzed by the IraMuTeQ software (R Interface for Multidimensional Text and Questionnaire Analysis), in which multivariate analyzes (similarity) were carried out to recognize the language probabilistic analysis of this group of students. The results show that this group of students indicates notions about uncertainty based on colloquial, intuitive language or even on meanings established by Portuguese language dictionaries. More specifically, it is considered that intuitive meaning constitutes a central and basic element, since it refers to those terms commonly used to refer to uncertainty or even the meaning of the word itself and express through colloquial phrases the quantification and the degree of belief in relation to uncertain events.
