O uso de imagens de satélite como recurso para a educação ambiental

Abstract

The objective of this study was to analyze the implications of the use of satellite images in the awareness buildup over the changes in the forest landscape in activities of Environmental Education in the scope of basic education (8th. grade) in the Manaus Public Schools. The other objectivities were: 1. Identify educational activities involving geo technologies and education in Brazil; 2. Check the student´s perception about the change on the landscape regarding the forest cover. 3. Check the student´s perception about the change on the landscape regarding the forest cover after the development of environmental education activities involving the use of satellite images. The identification of educational activities involving geo technologies and education occurred through the selection of all works published on the Proceedings of the Brazilian Symposium on Remote Sensing 1978 to 2013. The checking of perceptions of students about the modification of landscapes regarding the forest cover before and after the development of activities with satellite images was done through the questionnaires. In the first phase of this study questionnaires were applied to seventy five (75) students from the 8th grade of the basic education of three public schools of Manaus, covering knowledge on environment and technology. In the second phase twenty one (21) students were chosen from the same school to be capacitated about environmental questions regarding the forest cover and the use of satellite images. In the third and last phase, a final questionnaire was applied to chosen students aiming to check their perception about the changes of forest cover after the use of satellite images. With the aid of satellite images it was possible to work several aspects of the environmental dynamics regarding to forest cover, starting from local situations, recognized by the students themselves, until the knowledge of distinct realities belonging to different regions. It is estimated that this research will contribute to a better understanding of changes in forest landscapes and the capacitating of the use geo technological tools in Environmental Education activities with basic education students.
