To this end, a survey was elaborated and administered to a sample of 80 learners in the sixth year of primary school. Considering the important role of teachers in processing representations, we also investigated the teaching practices of a sample of 50 teachers and their representations of the concepts "Electricity and Light". The main results have shown that almost half of the learners (46,25℅) still confused the concept "Electricity" with the concept "Light", and the majority (94℅) thought that batteries contained electricity. These same representations, with practically the same rate, have been found among teachers as well. Concerning the management of the learners' representations, most of the teachers have declared that they didn't exploit them in class and explained their persistence by the fact that these erroneous representations originated from the learners' family and social environment.
