Irene Mauricio Cazorla; Miriam Cardoso Utsumi; Sandra Maria Magina – International Electronic Journal of Mathematics Education, 2023
This article aims to present a first approximation of the conceptual field of measures of central tendency (MCT), grounded in the theory of conceptual fields. We propose six situations according to type of variable, data presentation (raw or grouped) and amount of data. We revisit specific situations for the mean and exemplify several…

Gumiero, Bárbara Silva; Pazuch, Vinícius – International Electronic Journal of Mathematics Education, 2021
Mathematics classes have contingency situations in the relationship established between teacher and students. The objective of the article is "to understand the dimensions of the teacher's knowledge that are constituted in the development/execution of tasks on geometric concepts in interaction with students." For this, a collaborative…

da Fonseca, Vilmar Gomes; Henriques, Ana Cláudia Correia Batalha – International Electronic Journal of Mathematics Education, 2020
The literature emphasizes the interest and need to learn the concept of continuity with understanding, although this meaning it is not consensual nor specified how it may emerge and be developed in the learning process. In this paper we report the results of a study aiming to analyse Brazilian preservice mathematics teachers' understanding of the…

Alves, Francisco Regis Vieira; Vieira, Renata Passos Machado; Catarino, Paula Maria Machado Cruz – International Electronic Journal of Mathematics Education, 2020
In this work, recurrent and linear sequences are studied, exploring the teaching of these numbers with the aid of a computational resource, known as Google Colab. Initially, a brief historical exploration inherent to these sequences is carried out, as well as the construction of the characteristic equation of each one. Thus, their respective roots…
