Abstract

This work presents na experience report that involves the production and development of a didactic sequence for two first year high school groups. The sequence was described and commented in order to evaluate its contribution to the teaching and learning of chemical concepts under the STS (Science - Technology - Society) approach. We used contextualized activities concerning the development of students’ interest and involvement, so they are able to use concepts and arguments in discussions related to the construction and exercise of their citizenship. The following instruments were used for data collection: field diary, questionnaires, students’ essays and written exam. Data analysis revealed that the sequence, as it was organized, provided the students with the learnig of chemical concepts associated with social, economic and environmental aspects, as well as contributed to the involvement of students, who were interested and participative in the proposed activities.
