CARDONA RIVAS, Dora  y  TAMAYO ALZATE, Oscar Eugenio. Argumentation models in science: an application to genetics. Rev.latinoam.cienc.soc.niñez juv [online]. 2009, vol.7, n.2, suppl.1, pp.1545-1571. ISSN 1692-715X.

1. Goal. To characterize argumentative models through biology students in the solution of genetics problems, from the conceptual model, argumentative structure and discursive behavior categories. 2. Materials and Methods. A qualitative study with a descriptive-type methodology was conducted, where the written and oral responses of four (4) students were analyzed. To gather the corresponding information, seven (7) problems were designed, where Lamarck and Mendel's heritage models were implied. To analyze the information, discourse and content analysis procedures were applied to the oral and written texts. 3. Results. At the moment of solving the problems, the students participating in the study used restricted argumentative structures, a discursive behavior characterized by the frequent use of possibility connectors and deictics, as well as the heritage models that have preceded the molecular model. The argumentative models characterized become the basis for didactic interventions in the field of Genetics Teaching.

Palabras clave : argumentative model; argumentative structure; discursive behavior; conceptual model; genetics; didactics.
