The paper outlines a proposal of twodimensions of the competence: (1) metaknowledge, or knowledge about the use of evidence,including nature of evidence, its role, and criteria for evaluating evidence; and (2) practice ofthe use of evidence, including the use of evidence in different contexts and the operationsinvolved in it. The different elements in the proposal are discussed drawing from the literature,and particularly from the authors’ studies with two tasks set in socio-scientific contexts:evaluation of Watson’s claim about differences in intelligence between ‘races’, and decisionabout the ecological efficiency of eating secondary versus tertiary carnivore fish. The difficultiesfound, both in secondary school and in university students, point to the need to pay specificattention to this dimension of argumentation PB Universidad Nacional Autónoma de México.
