A importância da experimentação como ferramenta didática no processo de ensino e aprendizagem dos conteúdos de eletroquímica

Abstract

The present work aims to investigate and understand the importance of experimentation as a didactic tool in the teaching and learning process of electrochemistry contents in three classes of 4th year of high school integrated to the Technician in Administration, Electrotechnical and Computing of IFPI, Campus Picos PI. The work was characterized as an exploratory and descriptive field research with a qualitative approach. The research was developed from bibliographical surveys, in which it was possible to verify the perception of different authors about the importance of experimentation in the development of students' scientific knowledge; analysis of the electrochemistry content of the book of the second year of high school adopted by the IFPI in the year 2015, in which it can be seen that the contents were exposed in a very general way; and observation of the experiments carried out by the students in the three groups, where it was possible to verify that they demonstrated mastery of the contents and were able to assimilate the theoretical knowledge with the practice performed, demonstrating great enthusiasm during the presentations. To obtain data were used online questionnaires and observations of the experiments. With the answers obtained by the questionnaire and the observations made, it was possible to perceive the great importance in the students' conception about the use of experiments during chemistry classes, favoring the improvement of scientific knowledge, in a contextualized way. We can conclude that experimentation as a didactic tool in the teaching of electrochemistry facilitates the transmission and understanding of the contents, proving to be an indispensable tool in the process of development and improvement of students' chemical knowledge
