ERRORES CONCEPTUALES EN GEOLOGIA: LOS CONCEPTOS ISOTROPIA-ANISOTROPIA Y PROPIEDAD ESCALAR - PROPIEDAD VECTORIAL
Revista Enseñanza de las Ciencias.
"Herein an analysis is offered of the conception that first cycle university students have about the terms Isotropy-
Anisotropy and Scale properties-Vectorial properties, that have been learnt only within the school limits. It seems,
therefore, that if there are conceptual mistakes, they must be blamed on the Teaching-Learning system, and not on the
previous ideas students might have."
