Uma sequência didática para o ensino de eletroquímica nos curso técnicos em eletrotécnica e edificações no IFG câmpus Jataí

Abstract

Chemistry teaching is presented to students detached from their reality with complex theories and, consequently, this causes difficulties in learning and interest in chemical content, which is one of the challenges faced by teachers in classrooms. Thus, procedures are needed to assist the act of teaching so that students are encouraged to investigate, arousing in students the interest in science. In this context, this research used experimental activities, promoting the understanding of the fundamentals of electrochemistry and the cognitive development of students, since research has shown that experimentation is one of the alternative methodologies in obtaining the contextualization of the taught content. In this sense, the project analyzed the importance of experimental activities in the construction of knowledge of 24 students of the 2nd year of the technical course in Electrical Engineering and of 25 students of the 2nd year of the Technical Course in Buildings integrated to the High School of the Goiás Federal Institute, Câmpus Jataí . The research was applied in two meetings and consisted of presenting the experiments before the students had contact with the content, in order to study the process in the construction of knowledge and to know the difficulties faced by these students regarding the teaching of electrochemistry in the discipline of. chemistry in high school. Data collection was performed through questionnaires answered after the experiment and the interpretation of the data obtained was based on Content Analysis. It was found that experimentation enabled interaction between students, the understanding of content and the construction of electrochemistry concepts.
