Abstract
En el presente trabajo de investigación se evaluó la percepción de aplicaciones de anatomía 3D en relación a una estrategia de enseñanza basada en fundamentos cognitivos de la manipulación de imágenes digitales. Dos grupos de estudiantes ingresantes a la carrera de medicina recibieron entrenamiento en el uso de aplicaciones de software de anatomía en 3D, pero sólo uno de los grupos recibió información adicional sobre las limitaciones de la memoria en la retención de imágenes tridimensionales y estrategias para el uso apropiado de los controles de rotación que evitan la sobrecarga cognitiva. La percepción se evaluó con un modelo de aceptación de tecnología (TAM) y se constató una diferencia significativa entre ambos grupos a favor del grupo entrenado. Inferimos que la incorporación de aplicaciones de anatomía 3D en dispositivos tradicionales de pantalla 2D, tendrá mayor aceptación (es decir, probabilidad de uso futuro) cuando esté acompañada de una estrategia de autoregulación para evitar los efectos de desorientación que producen las rotaciones no controladas características del uso autodidacta.
In this research work the perception of 3D anatomy applications was evaluated inrelation to a teaching strategy based on cognitive foundations of digital image manipulation. Twogroups of students entering the medical career received training in the use of 3D anatomy softwareapplications, only one of the groups received additional information on memory limitations in theretention of three-dimensional images and strategies for appropriate use of rotation controls thatavoid cognitive overload. Perception was evaluated with a technology acceptance model (TAM)and a significant difference was found between both groups in favor of the trained group. We inferthat the incorporation of 3D anatomy applications in traditional 2D screen devices will have greater acceptance (that is, probability of future use) when it is accompanied by a self-regulation strategy toavoid the disorientation effects produced by the characteristic uncontrolled rotations in self-taught use.
