Saberes del alumnado de secundaria sobre el modelo de inmunidad y vacunas.

This article investigates the knowledge of secondary school students about immunity and vaccines, using an open-ended questionnaire along with its evaluation rubric. Thus, the rubric includes four response categories for each question, whose meanings reveal the kinds of ideas held by the students. The qualitative results obtained show ideas that are not very consistent with the referent learning model for immunity; however, an analysis of Rasch shows articulated knowledge, which is evidence through the unidimensionality of the measurements obtained. This suggests the possibility of using them as a guide to a possible progression itinerary that facilitates student learning over the course of their education. These results not only have implications at a theoretical and classroom practice levels, but also entail the validation of the rubric constructed for use with this student population.
