Puntos de no-derivabilidad de una función y su importancia en la comprensión del concepto de derivada

Abstract: Resumen Este estudio analiza la importancia del tratamiento de puntos de no-derivabilidad en la tematización del esquema de derivada. Para ello, se consideró el marco propuesto por la teoría APOE, a través del uso y conexiones lógicas que los estudiantes universitarios establecen entre los elementos matemáticos y los modos de representación cuando resuelven tareas sobre derivada. Se utilizaron dos instrumentos: el primero fue un cuestionario conformado por tres tareas propuestas en distintos modos de represent… Show more

“…We highlight the work done by S3 where he made mathematical connections of implication type (quality level 2) to graph considering the information provided by '. In contrast in Fuentealba et al (2015), and Fuentealba et al (2018aFuentealba et al ( , 2018b it was evidenced that students find it difficult to carry out reversibility processes, such as linking the signs of 'and ′′ to analyze the behavior of . Also, in García-García and Dolores-Flores (2021a) the majority of students do not proceed visually to graph the antiderivative from the derivative (or vice versa), but they give priority to algebraic representations, so they established more mathematical connections of procedure and other students recognized the reversibility after having graphed.…”

“…It should be noted that in response to task 8, S3 used reversibility relationships between and ' since he sketched the graph of from the information offered by '. In this context, it was placed at a level 2 of connection quality since they are justifications and mathematically consistent processes that could promote the understanding of the derivative concept (Borji et al, 2018;Fuentealba et al, 2015Fuentealba et al, , 2018aFuentealba et al, , 2018b.…”

“…De hecho, Ubuz (2007), consideró que era difícil para los estudiantes utilizar la información gráfica para dar sentido a las representaciones simbólicas. Además, los estudiantes no comprenden la derivada porque tienen dificultades para relacionar tanto el crecimiento como el decrecimiento de y el signo de ′ y ′′ y trabajan más con información gráfica y el significado analítico puntual de la derivada (FUENTEALBA et al, 2018;FUENTEALBA, BADILLO y SÁNCHEZ-MATAMOROS, 2018).…”
