Análisis de la metodología utilizada en la busqueda de «lo que el alumno sabe» sobre fuerza

In a previous paper we compared research carried out in the decade 75-85 on students’ conceptions of «force» with later research in the period 85-95. Only a slight progression was found in the results offered by different authors. The aim of the present paper is to analyse the reasons for this lack of progress in the research results, as regards the appearance of conceptions. To the end we have analysed the research objectives of the selected papers, their methodological characteristics and their most widely used theoretical foundations.
