Este estudo investiga a potencialidade do ensino da estrutura de um "bom" argumento, baseado no Esquema de Argumento de Toulmin, como apoio ao desenvolvimento de habilidades argumentativas de alunos de gradua&#231;&#227;o em qu&#237;mica. Os resultados indicam que esse tipo de interven&#231;&#227;o did&#225;tica oferece subs&#237;dios para o desenvolvimento das referidas habilidades.]]></p></abstract>
