Abstract:
This work approaches the process of modelization in the Natural Science Teaching, more specifically in the teaching of Biology. First, models and modelizations in the teaching of sciences are approached conceptually. After, the example of modelization of the alimentary chain is presented and finally, describes a situation occured in classroom in which the process of teaching learning, mediated for the models is analyzed. For in such a way, a didactic situation developed in 4a was used series of basic education on the subject "alimentary chain". They had been used in this process of teaching, the models and representations presented in didactic books of different series, also of the average and superior level. As conclusions we point that the models must be used as aproximativos resources and not as realities. As instruments of explanation and forecast produced with the intention of one better understanding of the faced educative problems. In this process, the paper of the professor is basic, in the implementation of the situations of necessary interaction and learning.
