La enseñanza de la química ambiental: Una propuesta fundamentada en la controversia científica y la resolución de problemas

In this work a study conducted in the academic area of “Environmental Chemistry”, of sixth semesterBachelor of Chemistry, specifically on the issue of water resources, its importance, physicochemicalanalysis of water contamination and treatment presents same, with the intention of seeking theimprovement of education, building knowledge and skills development in the field of Initial TeacherTraining Chemistry. For it was designed and implemented the teaching unit called “water resourceand abuse,” which was organized using problem solving and socio-scientific controversy, thedevelopment of this unit comprised three stages: the first in which identified alternative ideas thatstudents had related to the concepts of chemical change and water, the latter concept is exploredboth from the chemical point of view and from the importance to ecosystems and human life; inthe second stage a series of activities seeking the reconstruction of alternative ideas were designed,these activities included video analysis, development labs from the show in a body of water,physicochemical analysis of water samples, visit a plant water treatment and group work aroundsocio-scientific controversies related to the importance of water conservation and the different methodsof treatment for drinking water and in the third stage, monitoring and analysis of classroomactivities performed and laboratory developed during the implementation of the teaching unitallowing to identify the learning processes. The work accomplished promote understanding andconstruction of chemical knowledge related thematic analysis and water treatment as well as thecommitment of the man in the care of water resources, just as the student progress in developingevidenced the argumentative and interpretive proactive about water as a water resource skills, thisled to the conclusion that teaching is based on socio-scientific controversy and troubleshootingbecomes more dynamic the teaching-learning process and encourages the building of concepts.
