Os experimentos de Griffith no ensino de Biologia: a transposição didática do conceito de transformação nos livros didáticos

Griffith's experiments regarding bacterial transformation Pneumococcus are regarded as essential when related to DNA/heredity recognition process. The aim of the current study is to assess the didac tic transposition of the concept of bacterial transformation since the Griffith's descriptions until its current approach on didactic books. We realized that the historical context and the relationship between bacterial transformation and DNA recognition as genetic material are poorly explored. The core of our paper is the historical approach of those exper iments. By considering the wide richness of the knowledge that is ranged on Griffith's experiments, we suggest a didactic transposition concerning bacterial transformation in the learning process, involving an integration of contents.
