URIBE, Manuel; QUINTANILLA, Mario; AYMERICH, Mercé Izquierdo i  and  PAIROS, Nuria Solsona i. Aplicación del modelo de sthepen toulmin a la evolución conceptual del sistema circulatorio: perspectivas didácticas. Ciência educ. [online]. 2010, vol.16, n.01, pp.61-86. ISSN 1516-7313.

In this article is presented a brief systematization about the evolution of the concept of blood circulation that considers the historical period between the conceptions of the Egyptians until century XVII, when Harvey consolidates a “scientific model of Sanguineous Circulation” in the human organism. Next, we applied the model of Toulmin to analyze blood flow, valves and cardiac frequency evolution concepts from pragmatic to a realistic perspective. Finally we raised some ideas that could serve as a guide for the education of this concept considering the historical aspects that we had analyzed.

Keywords : Pragmatic Realism; Science Education; Toulmin’s Model.
