La plataforma Moodle se mantiene como “el sitio oficial” para desarrollar cursos en línea en la Universidad de Guadalajara, sin embargo, desde mi punto de vista es muy poco práctica. La gota que derramó el vaso de la ineficiencia fue el mensaje de error cuando intenté subir el material que se utilizará en el curso “Introduction to polysaccharide characterization and their physicochemical properties” de la Dra. Marguerite Rinaudo:
