Abstract
El objetivo es analizar la influencia de la tarea en el uso de pruebas y modelos conceptuales al resolver un
problema sobre la sustentabilidad de la acuicultura. Los participantes son 134 estudiantes universitarios de
biología de tres cursos. La tarea solicitaba comparar desde el punto de vista de la eficiencia ecológica
alimentarse de arenques y sardinas o de salmones. Se comparan resultados de un curso en el que habían
realizado un mapa conceptual sobre la eficiencia ecológica con los de dos en los que no se había hecho. Los
resultados muestran diferencias sustanciales tanto en el uso de modelos de flujo de energía y pirámide
trófica como de pruebas. Estas diferencias ponen de manifiesto la necesidad de prestar atención al papel de
los conceptos al diseñar actividades para desarrollar la competencia de uso de pruebas
The objective is to analyze the influence of the task in the use of evidence and scientific models while solving a problem about the sustainability of aquaculture. The participants are 134 biology undergraduates, from three consecutive years. The task asked them to compare the ecological efficiency of eating sardines and herrings or salmons. Results from one cohort when students had elaborated a concept map about ecological efficiency are compared with results from two cohorts when they had not. The findings show substantial differences both in the application of the models of energy flow or trophic pyramid and in the use of appropriate evidence to justify their claims. These differences point to the need to pay attention to the role of conceptual knowledge when designing activities in order to promote the development of the scientific competency in using evidence
