Abstract
El objetivo del presente trabajo ha sido detectar la evolución de algu
nos conceptos relacionados con las membranas celulares en el alum
nado de Enseñanza Secundaría y de la Licenciatura de Ciencias Bio
lógicas. Los resultados obtenidos muestran que, mientras los concep
tos referentes a estructura y unidad de membrana evolucionan favo
rablemente, se produce un deterioro en la comprensión de los con
ceptos relacionados con sus funciones, tanto en Enseñanza Secunda
ria como en la Licenciatura. Esta situación puede ser debida a que,
durante la Enseñanza Secundaria, el aprendizaje de la organización
celular queda reducido a la simple memorización de las parejas orgá
nulo celular/función, que en poco tiempo son olvidados o confundidos.
En la Enseñanza Universitaria, los alumnos, ya sea por su propia de
formación y/o por planteamientos didácticos erróneos por parte del pro
fesorado, siguen planteándose el estudio de la organización celular
como una simple memorización. No terminan de comprender la rela
ción estructura molecular/función celular, ni como las funciones celu
lares dependen de las funciones de las macromoléculas y de las di
versas interacciones de estas en las distintas estructuras celulares que
constituyen.
The main objective of the present survey is to detect the evolution of Biology student’s conceptions about cell membranes from Secondary School to University. The analyse of the results shows that the students´ conceptions about the structural unity of biological membranes evolve positively in contrast with the concept of functional diversity of biological membranes that evolves negatively. The reason could be that in Secondary School the learning of cell organisation is proposed as a memorizing of the pairs cell organ/function, easily forgotten or mistaken. The University students carry on with the study of cell organisation as a memorizing exercise, not understanding the relation between molecular structure and cell function. They do not understand either that cell functions depend on macromolecules functions and on the different interactions of the macromolecules constitutive of the cell structures. As a conclusion, we think that it is very important to focus the teaching of cell organisation defining in molecular terms the cell organisation and how the cell functions depend on macromolecule functions and interactions in the different cell structures.
