The language of music as a possibility of social criticism: results of a research-action in the context of public schools
This article presents the results of a collaborative research-action carried out at a public school in the city of Cruz Alta, Rio Grande do Sul(RS). The activities carried out aimed to promote the improvement of teaching in the public school, so that the methodology of the research-action was configured as an alternative proposal to carry out a work with the engagement of all involved. The option for this methodology is justified by the fact that it contributes to solve problems in specific contexts, especially in the educational context.
