Un estudio sobre el papel de las analogías en la construcción del modelo cinético-molecular de la materia

Abstract

In order to analyze the role of the analogies on the model construction about scientific phenomena in the students, a theoretical framework is firstly proposed. From this framework, a concrete didactic design is also proposed with regard to facilitating the construction of a kinetic-molecular model of matter through analogies, in students of compulsory secondary education. Finally, the didactic design used is evalua­ted, comparing the final results in the interpretation and prediction of phenomena between an experimental group and a control one. The post-test results indicate that the analogies used played a relevant role in the learning process of the pupils who were taught through the mentioned resource. They provided, finally, explanatory models more in agreement with the scientific model than the pupils who were taught according to a similar design but without analogies, although the differences found were small.
