Educação ambiental e o tratamento de água: uso do sistema de tratamento de água baseado em ultravioleta em Câmpus do Instituto Federal do Maranhão e sua relação com a construção de conhecimentos

Abstract

Research in Environmental Education Criticizes aims to construct and reflective critique of knowledge allowing individuals greater contextualisation-environmental relations and consequent changes, in attitudes towards collective transformation of reality. The municipality of Zé Doca, regional pole of Turi, located east of the State of Maranhão, in the Northeast region near the border with the State of Pará, is responsibility to articulate educational actions, political and economic, social and environmental development of over 17 other municipalities in the region. It was found that municipalities the environmental sanitation and water treatment is performed unsatisfactorily and precarious, signaling the need for sustained research-driven actions on the principles of education Wake up in the population capable environmental more questioning and intervention in the local reality. This research aimed to instigate critical knowledge construction to allow greater local perception of reality, associated with insertion technique feasibility research, Community research, alternative technology of water treatment based on ultraviolet radiation-UV Tube. The Methodological development used by this social research was action research procedures where awareness, dynamic cooking workshops, adaptation and installation of UV Tube, meetings and other educational practices addressed the theme of water treatment, social issues, environment and health, among other correlated in a participative manner, reflective and harmonic among respondents and researchers. The search area was chosen as the community of rural settlement good hope, located in Zé Doca, where were installed and evaluated 05 (five) UV Tube units. Data collection took place 64 (sixty-four) interviews and questionnaires applied before the dynamics of awareness and at the end of the whole educational process in order to identify improvement in the perception of the community in relation to the subject dealt with and the local reality, and consequential changes in attitudes. The treatment of data collected in the questionnaires presented variables that were tested with the non-parametric test of Chi-square and other calculated averages of answers with their respective standard deviations and their minimum and maximum values. The results indicated favourable conditions for the adaptation and insertion of the UV tube technology showing economic viability and operational compared to similar projects successfully installed in other countries, especially the acceptance of the proposal and the ease of access to the materials needed to manufacture of UV Tube. As the analysis of educational activities related to the thematic discussion addressed significant responses were expansions and modifications in order to understand the local reality criticizes pointing, including changes to posture that assisted the search for better quality of life for the community. It is concluded that the implementation of concrete action of insertion of the UV Tube use, Dialogic and critical process of construction of knowledge based on the intrinsic relationship between action and reflection associated with the permissive criticizes of knowledge built by researched and researchers was the recipe to achieve the objectives of the survey.
