Formação continuada de professores de química do ensino médio para a realização de experimentos investigativos com materiais de baixo custo

Abstract

The use of experiments in chemical education has been increasingly encouraged discussed in the initial and continuing education of teachers for assisting the teaching and learning of concepts of this theme. There are different approaches in conducting experiments, as demonstrative, illustrative and investigative. In this work we chose to discuss the investigative approach, testing for formation of chemical concepts with teachers of high school chemistry the public schools of the city of Campo Grande - MS on a continuing education course titled 'Investigative Experimentation with low cost materials'. To meet the reality of the absence of laboratories, reagents and glassware in the public schools of our city, we work with these teachers investigative experimentation with low cost materials. Therefore, we approach the reality of these professionals become more significant and continuing education. In order to meet these professionals feature a high number of working hours distributed in three shifts, continuing education proposal consist of a semi-distance course in 40h with two onsite meetings. The steps performed from a distance had the support of the Moodle platform. The survey was developed in order to analyze if the course distance continuing education on investigative experimentation with low cost materials contributed to the appropriation of knowledge about the practice of investigative experiments by teachers of chemistry. After conducting and analyzing the information collected, we conclude that the course contributed to the improvement of performing experiments by teachers in general, not necessarily using the investigation. The course 'Investigative Experimentation with materials Low Cost' to appropriate the knowledge about the practice of investigative experiments so as not investigative by teachers and to exchange ideas and experiences, promoting the improvement of performing experiments in classroom.
