Estudo do processo de aprendizagem significativa sobre órbitas de satélites e o imageamento da superfície terrestre num curso técnico em agrimensura

Abstract

This article is about a qualitative case study research, in which it was sought to understand the process of Meaningful Learning about satellite orbits and the imaging of the Earth's surface, by students of a Technical course in Surveying. The motivation for this research came from the students' difficulties in differentiating the way of obtaining the images generated by satellites and the aerial photographs, obtained by airplanes and drones. To solve this problem, we developed a didactic sequence based on David Ausubel’s Meaningful Learning Theory, that contained a representative model of orbital movements of an observation and Earth rotation satellite, which was applied to a class from the last period of the subsequent Technical course in Surveying of the Federal Institute of Goiás, IFG - campus Jataí. In this dissertation, we will present the results of the analyses of transcriptions of class recordings, of the application of the didactic sequence and of the conceptual maps prepared by the students. From these results, we were able to infer that the model was set up as a potentially significant didactic resource, allowing students to visualize the combination of the orbital movement of a satellite and the rotation of the Earth, which allows the imaging of the Earth's surface. In the concept maps that were developed by the students, we could identify both signs of progressive differentiation and integrative reconciliation, which is an indication of meaningful learning of the concepts treated here. This allowed us to conclude that the didactic sequence contributed to the meaningful learning about the orbital movement of satellites and the process of imaging of the Earth's surface.
