The notions of meaning and sense, which are closely related to understanding, play an
essential role in educational processes in general and, therefore, in the teaching and …

Researchers continue to emphasize the importance of covariational reasoning in the context
of students' function concept, particularly when graphing in the Cartesian coordinate system …

This study sought to examine the impact of dynamic mathematics software, GeoGebra, on
university mathematics students' understanding of polar coordinates. A quasi-experimental …

The objective of this research is to identify the effectiveness of the GeoGebra program in
developing academic achievement and ensuring survival of the learning impact of the …

This paper presents a conceptual analysis for students' images of graphs and their
extension to graphs of two-variable functions. We use the conceptual analysis, based on …

In this study we analyze students' understanding of two-variable function; in particular we
consider their understanding of domain, possible arbitrary nature of function assignment …

This paper conceptualizes spatial literacy as consisting of three overlapping domains:
visualization, reasoning, and communication. By considering these domains, this study …

APOS Theory is applied to study student understanding of the differential calculus of
functions of two variables, meaning by that, the concepts of partial derivative, tangent plane …

Para comprender las dificultades y conflictos de aprendizaje, es necesario analizar las
tareas matemáticas y los diversos modos de abordarlas por los estudiantes. Dicho análisis …

Tracing the path from a numerical Riemann sum approximating the area under a curve to a
definite integral representing the precise area in various texts and online presentations, we …
