Air pollution: a context for the development of competencies in the secondary classroom

This paper focuses on the study of the learning progress of a group of students aged between 16 and 18, while they were performing activities on a real and close problem, as is the quality of the air in cities. Indicators for the different competencies involved, and 4 levels of development in them have been defined. The teaching and learning process was carried out by applying selected materials which were developed specifically to treat this problem. The results show clear progress mainly in those aspects related to what students have to face in their lives beyond school walls.
