METAVISUAL STRATEGY FOR THE BUILD AND REBUILDING OF CHEMICAL CONCEPTS IN THE SYMBOLIC LEVEL WITH THE ASSISTANCE OF IMAGES

Considering the opportunity of reconstruction of ideas is very important for success in the learning process. For this purpose, a metavisual strategy was used, comparing images, one made by the students and the other presented by the researcher so they could compare and be able to rebuild their ideas, the latter an image based on a scientific accepted model. The research focus was the comprehension of the symbolic level by the learners while studying two electrochemical interactions by comparing images and rethinking about them. Thirty-two high school students, organized in pairs, participated in the research carrying out a proposed teaching and learning sequence (TLS) in the classroom. First, the students proposed hypotheses and then they had the opportunity to rethink about them modeling their learning. Students were filmed and the transcriptions and registers made by them were analyzed later. The results indicate a qualitative and progressive improvement in the learning of the subject when using the metavisual strategy, bringing evidence that it can be efficient to build and rebuild initial concepts in electrochemistry.
