The use of representational modeling and respiratory digestive system in science education as a pedagogycal tool: prospects for a meaningful learning in elementary school

Abstract

The modeling as a didactic tool aims to provide meaningful and enjoyable learning. Thus, this work aimed to the digestive system and respiratory education through representational modeling in order to collaborate with the learning of students. The work was carried out in day 8 of April 2015, with the class of eighth-graders in public school Council of Salvaterra, Marajó archipelago, para. At first, it was applied a questionnaire about knowledge of class about modeling, in which 94% said not having knowledge. With this brief introduction has been made of the subject to be discussed right after the class was divided into two teams (A and B), which made the Assembly of models from parts (each piece represents an organ) which were passed on. In addition, dynamic was made direct questions on the subject to the groups, where the team won with the highest number of hits. The issues were discussed with the intent to be no doubts. In the end, two questionnaires were applied, one on the importance of modeling in the discipline of science and another on an evaluative concept work, 96% and 60% of positive results, respectively. Most students were able to understand the information offered through the pedagogical resource applied because the teams did not have difficulties to assemble the models, which breaks the paradigms of classroom and extols the use of representational modeling in science education to a significant learning.
