Comprensión espacial de vectores mediante recursos digitales interactivos = Spatial comprehension of vectors by means of interactive digital resources

Dada la dificultad de vision espacial habitual en muchos de los estudiantes vinculados a titulaciones de caracter tecnico, en este articulo se presenta un recurso digital interactivo que ayuda a reforzar la comprension espacial de los vectores en el espacio (que suele ser una de las dificultades mas comunes entre los alumnos de primer curso de cualquier ingenieria). Esta herramienta permite al alumnado obtener ayuda para visualizar y analizar en tiempo real los cambios que se producen al variar las coordenadas de un vector: (i) el modulo del vector, (ii) su vector unitario y (iii) los cosenos directores. Esta plataforma virtual interactiva (PVI) pretende solventar, por una parte, la visualizacion espacial de los cosenos directores de un vector situado en cualquier octante y, por otra parte, la interpretacion espacial de la posicion de un vector cualquiera. Mediante el uso de esta PVI, el alumno realizara ademas un autoaprendizaje de tipo productivo, lo que favorece el habito de pensar, razonar y relacionar o explicar la informacion.  Abstract  Taking into account the common difficulties regarding spatial visualization appearing in students enrolled in technical studies, this paper presents an interactive digital resource that helps to enhance the spatial comprehension of vectors in 3D space (this one being one of the most common difficulty detected in first-year engineering students learning). This tool allows students obtaining assistance to visualize and to analyze in real time the changes produced in a vector when its coordinates are varied, namely: (i) vector modulus, (ii) the unitary vector, (iii) the director cosines. On one hand, the developed interactive virtual platform (IVP) tries to solve the spatial visualization of the director cosines of a vector placed at any octant and, on the other hand, the spatial interpretation of the position of a given vector. By using this IVP, students will perform a productive self-learning, enhancing the habit of the key habit of thinking, reasoning and relating or explaining information.
