A percepção ambiental das lagoas urbanas: uma sequência de ensino para a construção de conceitos e atitudes ambientais referentes à Lagoa Paulino, Sete Lagoas Minas Gerais

Abstract

The practice of Environmental Education in local contexts deepens the individual's knowledge of their actions in the environment and builds a comprehensive view of citizenship. Given the argument, addressing the environmental situation of urban lakes in Science Teaching is an alternative for the study and preservation of water resources located in urban space. Thus, we elaborate and developed a research teaching sequence to promote the learning of the ecological processes present in the urban lakes, taking as object of study the aquatic ecosystem Paulino lake located in the municipality of Sete Lagoas, Minas Gerais. Teaching sequences are important tools for promoting learning by building up in a constructivist and social perspective. The stages are based on intentional, structured and intensive activities adapted to the particular needs of the subjects and the social and environmental environment that will be the object of study. In this way, we seek in its steps (a) to determine the environmental perception by means of photographs of the Pauline lake captured by the research subjects, (b) to identify the previous knowledge in order to allow the induction of hypotheses about the causes and effects of environmental degradation, (c) to use research procedures for the development of concepts, (d) to analyze data and apply knowledge with evidence collection during a guided visit to the Pauline lake, and (e) to allow reflection through final production that culminated in construction of reports on the current situation of the Pauline lake. The analysis of the collected data helped to uncover, behind the apparent discourse, what previous knowledge the learners have regarding the aquatic ecosystem Paulino lake and the appropriation of environmental attitudes and ecological concepts during the development of the sequence. We believe that despite the focus on urban aquatic ecosystems, the basic structure of the teaching sequence can be employed in a multitude of environmental problems.
