Improvement of argumentation through experimental activities with a sociocultural approach in teaching corrosion

Abstract

This research analyzes the interaction between students and between teacher and students, by applying a didactic sequence based on experimental activities on the subject of corrosion, in order to verify how this interaction between subjects contributes to the improvement of students' arguments regarding the concepts covered. The instruments of analysis were constituted by the transcriptions of the video recordings of the classes, the responses of the groups of students to the questions associated with the experiments carried out during the classes, and the responses of the pairs of students to the questions of the evaluative activity carried out at the end of the process. The results of the analysis showed that such interaction enabled a space for dialogue in which the students actively participated, culminating in an improvement of the arguments of them.
