Application of Grey Numbers to Assessment of the Understanding the Graphical Representation of the Derivative

Abstract: Grey numbers, which are defined with the help of the real intervals, are very useful in the everyday life for handling approximate data. In the present paper grey numbers are used as a tool for assessing, with linguistic expressions, the student understanding of the graphical representation of the derivative. Although the proposed new assessment method is proved to be equivalent with an analogous method using Triangular Fuzzy Numbers developed in earlier works, the required computational burden is significantl… Show more

“…La literatura muestra que la derivada es importante para el desarrollo del Cálculo (DOS SANTOS, 2020; VERÓN y GIACOMONE, 2021) y que los estudiantes presentan dificultades para comprenderla (PINO-FAN et al, 2015;. De la revisión de la literatura, se concluye que los estudiantes proceden inadecuadamente cuando no se les da la expresión algebraica de la derivada o de la función (FERRINI-MUNDY y GRAHAM, 1994;VOSKOGLOU, 2017), pero sí muestran cierta comprensión cuando se les da la expresión algebraica. En esta línea, en esta investigación pretendemos respondemos a la pregunta ¿Dada la expresión algebraica de , qué conexiones aseguran al estudiante una comprensión de la derivada que le permite realizar un esbozo de la gráfica de y explicar la relación que tiene la gráfica de con la gráfica de '?…”
