Desenvolver a cidadania através da química : é possível? Um desafio a ser vencido
Resumen
The present work was inspired by the High School National
Curriculum Parameters (PCNEM) as well the Schnetzler proposal of teaching
chemistry to citizenship. It is also based on the observed chemistry teaching
problems, inefficiency of teaching methodologies and governmental programs.
Teaching chemistry under the viewpoint of maintainable social and environmental
development offers opportunities to relate the work to the customary student daily
life, the construction of concepts starting from facts, and of knowledge about
information bound to the human being survival. The interpretation of these
information was carried out using concepts already established and others concepts
were built up to understand the subjects. This work applied a new methodological
proposal (strategy) based on the constructive conceptions and the idea that
chemistry should be taught to build up the basic abilities for citizenship, seeking to
evaluate the teaching and learning process and also the method acceptance. The
approach to the contents took in account the interdisciplinary, using Chemistry
Science as a tool to interpret the facts in the real world. The results showed that
the applied teaching methodology, according to PCNEM, was able to improve the
student’s participation. The students started to act as managers of the learning
process, being capable to supervise and elaborate their own ideas comparing them
with the previously established scientific ideas. It was also observed that the
scientific activity became something joyful and gratifying to the students.
