Didactic Problems in the Concept of Electric Potential Difference and an Analysis of Its Philogenesis.

This paper makes an analysis of the different didactic problems to come from the fact that electric charge is inseparable from the mass, the impossibility of its direct observation (only its effects) and the meaning associated with the basic concepts of electricity, like electric potential or electric potential difference.In order to know the origin of the different meaning found in textbooks of the concept of electric potential difference, we have made an analysis of the relevant historical milestones. In this review, it is seen that the content assigned to it is taken from the mathematical formalism of field theory, which causes problems in its structure and its logico-formal communication as well as teaching problems.

Revisión bibliográfica sobre la evolución de las "ideas" de los alumnos sobre el concepto de fuerza en situaciones de equilibrio estático

En este trabajo se pretende analizar la situacion actual de las “ideas” de los alumnossobre el concepto de fuerza cuando se le plantean situaciones de equilibrio estatico.Para ello, se ha tomado una muestra amplia de trabajos y se han establecido una serie decategorias para unificar criterios y hacer comparables los datos aportados por losdiferentes trabajos seleccionados.
