Investigación de las ideas de los alumnos de enseñanza secundaria sobre la corriente eléctrica

Resumen

This paper deals with the ideas on electric current of secondary education (BUP and COU) students who have been given traditional tuition. The study was based on open -choice questionnaires, word -choice tests and concept trees. The results obtained show that the students' experiential and environmental models acquired from their everyday physical and social experience are preserved throughout their secondary education. However, their vocabulary gradually conforms to the «scientific model» of elect! ic current.
