Dissemination of remote sensoring in interioran municipality: experience in school of Pé de Sierra -BA-Brasil

Abstract

Remote sensing stands out because it is a geotechnology that allows interpreting data from the terrestrial surface, making it a very useful didactic resource for teaching. Most of the research carried out with remote sensing as a didactic tool is done in large urban centers, and it is necessary to diffuse this geotechnology into small municipalities. The objective of this work was to show how remote sensing can be used in inner city schools to work geography contents contextualized with local reality. The research was carried out at the Luís Eduardo Magalhães Municipal School, located in the municipality of Pé de Serra -BA, with four classes of 9º grade (78 students) of Basic Education, in the morning and afternoon shifts. For the application of the study, three steps were followed. In the first one, a diagnosis was made about the students' previous knowledge regarding remote sensing and geography classes. In the second, a workshop was held with a theoretical and a practical part. In the theoretical part, the concept of remote sensing was presented through slides, the main characteristics of this technology, besides the use and application of satellite images. In the practical part was provided to the student contact with satellite imagery, Google Earth of his municipality. From the satellite images, sketches of the space lived by the students were constructed. In the third stage a questionnaire was applied to identify the learning acquired during the workshop. In the first stage of the study, 59% of the students stated that they did not know about satellite images of their municipality, 100% did not know what remote sensing was, 77% said that geography classes and textbooks were not contextualized with local reality. In the second stage, the target audience made good use of the concepts and characteristics related to remote sensing technology, their usefulness in local landscape studies and environmental studies, as well as the production of sketches to represent elements of the lived space. By manipulating satellite images and constructing the sketch, students have shown curiosity and interest in identifying landscape elements. The third stage of this study was important to understand how students have advanced in relation to knowledge about remote sensing, as well as the importance of this technology to study their locality. When asked about what most attracted attention in the satellite images of his municipality 37% highlighted the decrease of the vegetation of the municipality, 32% highlighted the quality ofthe images to study the municipality. Thus, it is concluded that Geography teaching should allow the student to understand their space and for this there are technological resources such as remote sensing that holds great importance in education. It is perceived with this work the need to disseminate remote sensing in schools of inner cities because the teacher has not used it in the classroom and many students still do not know this technology which is a dynamic and attractive form in the teaching-learning process.
