da Fonseca, Vilmar Gomes; Henriques, Ana Cláudia Correia Batalha – International Journal of Mathematical Education in Science and Technology, 2023
This study is based on an exploratory teaching experiment, integrating the use of GeoGebra, carried out with Brazilian pre-service mathematics teachers that were attending a Pre-Calculus course. We focus on the contributions of GeoGebra to the learning that the students evidence about the 'instantaneous rate of change', in this teaching experiment…

Cavalheiro, Adail de Castro; Grebot, Guy – International Journal of Mathematical Education in Science and Technology, 2022
This work presents an evaluation of a unified Calculus 1 course in a large Brazilian federal university. By course unification we mean having all the sections following the same weekly schedule, under the same syllabus and common assessment. We analyse two sets of data: pass rates relative to the 9 semesters prior to the unification and to the…

Marmur, Ofer; Moutinho, Ion; Zazkis, Rina – International Journal of Mathematical Education in Science and Technology, 2022
This study aims to explore the notion of the density of the set of rational numbers in the set of real numbers, as interpreted by undergraduate mathematics students. The data comprise 95 responses to a scripting task, in which participants were asked to extend a hypothetical dialog between two student characters, who argue about the existence of…

Campos, Dilhermando Ferreira; Pinto, Márcia Maria Fusaro – International Journal of Mathematical Education in Science and Technology, 2016
In recent years, changes in the Brazilian economic and social scenario have generated a growing demand for higher education in the country. In response to this new context, the federal government launched in 2007 a programme aiming at expansion of the enrolment to public higher education. In such environment of changes, several proposals have…
