Abstract

This study investigated the development of the conceptions of High School students from the NRE of Apucarana (PR), on the topic "Salts and Solubility" with using the software "Salts and Solubility" after the formal contact of the subject. We had starting up with a hypothesis that students do not appropriate correctly the meanings attributed to the concept of solubility, in the submicroscopic level, since they usually only establish contact with the macroscopic world, in everyday examples. Thus, the teaching situation, with the use of the simulator, enabled students to achieve a more effective level of submicroscopic observation. The results allowed the monitoring before, during and after the implementation of the software and, therefore, it was possible to reorganize explanatory levels and the analysis of the evolution of meaning construction of the students. The final interpretation indicates that the use of digital resource helped students to achieve better results in relation to the submicroscopic understanding of the phenomenon. Without this precious resource, students, mostly of them, could not design the nearest meanings of the scientifically accepted model in the investigated size (submicron).
