| Abstract: | Research has shown that students’ alternative conceptions in science are quite resistent to change, which indicates that the teaching strategies used are not appropriate and that new strategies should be implemented in order to promote conceptual change. This pilot study was carried out with 100 Portuguese 5th grade students and aims: (a) to investigate a teaching strategy geared to the students’ conceptual change, taking into account their misconceptions about scientific ideas; (b) to promote a better attitude towards science. The results of this study indicate that the teaching approach based on the pupils’ alternative ideas and that makes them reflect on their own work and ideas, seemed to increase learning of scientific concepts related to the topic ‘properties and corpuscular model of the air’ and consequently favoured conceptual change better than a ‘traditional’ approach. |
