El quehacer científico versus el quehacer áulico : buscando rasgos del quehacer científico en libros de texto

摘要

Here we outline a search for features of the scientific tasks in the paper-and-pencil and experimental activities proposed in the textbooks mostly used in Tandil. The topics selected were electric current, direct current circuits and electrical current effects. Among other results, it is worth nothing the notable variability found concerning the link between model and reality. There are also some reflections on the lack of emphasis in the conceptual analysis, on the possibility of diversifying the ways for the solution and the discussion on the relevance of mathematical expressions and numerical values.
