%0 Journal Article %T El papel de los modelos en la pr¨¢ctica cient¨ªfica %A ROSA NIDIA TUAY %J Revista Cientifica %D 2012 %I Universidad Distrital Francisco Jos¨¦ de Caldas %X Two decades of discussion about models as a basis for research and scienti- fic knowledge¡¯s advances have allowed to open a new way in an space, which was in darkness due to prevail of theories in its important approximations during XX century. According to this view, there is a big motivation to find new ways about science, not only less dependent of Theoric Physics episte- mology, but also more accurate to real practices in physics and also in other sciences. The purpose of this article is to describe different alternatives and positions about model¡¯s functions as representation and its frequently uses, which are established between scientific conceptual and material¡¯s work. This view allows to take a position by the optimal conditions to tackle scien- ce¡¯s dynamics and its teaching. %K models %K scientific representations %K scientific practice. %U http://revistas.udistrital.edu.co/ojs/index.php/revcie/article/view/4026/6033
