Métodos e técnicas do trabalho de campo no ensino da geologia

Abstract

No actual contexto das escolas surgem alguns obstáculos de natureza conceptual e metodológica à realização de actividades de campo. Com este trabalho pretende-se uma abordagem do trabalho de campo nos conteúdos programáticos de Biologia e Geologia do 11º ano, integrando os conceitos gerais relativos aos principais tipos de ambientes geológicos e litologias associadas e alguns conceitos estruturantes do pensamento geológico, disponibilizando informação de carácter genérico sobre a geologia de vários locais e produzindo materiais didácticos de suporte visando facilitar a preparação e a aplicação de actividades práticas de campo. Cada actividade prática de campo é constituída por um conjunto de elementos de introdução à actividade, um guião da actividade de campo e algumas sugestões de resolução do guião. A este nível o objectivo das actividades práticas de campo não é formar geólogos mas sim desenvolver atitudes, procedimentos e conceitos básicos em geologia que permitam a compreensão e a interpretação dos fenómenos geológicos. O modelo de guião proposto caracteriza-se por um desenvolvimento em três fases - preparação, trabalho de campo e síntese - e em ambientes diferentes: sala de aula/campo/sala de aula. As áreas seleccionadas situam-se na Zona de Ossa Morena (Alto de São Bento, Évora), Orla Ocidental (Fanhões, Montachique, Praia da Bafureira e Maciço Eruptivo de Sintra e região envolvente) e Zona Sul Portuguesa (Mina de São Domingos, Mértola). Na Zona de Ossa Morena e na Orla Ocidental foram seleccionados locais onde serão abordados aspectos relacionados com os ambientes magmático, metamórfico e sedimentar. Na Zona Sul Portuguesa será privilegiado o impacto ambiental causado pela Mina de São Domingos; ABSTRACT:In the current context of schools some obstacles have arisen to the conceptual and methodological implementation of field activities. With this work we intend to reach an approach to fieldwork in the Biology and Geology syllabus, in the 11th form, integrating the general concepts related to the main types of geological environments and associated lithologies as well as structural concepts of geological thought, providing general information on the geology of various places and producing support teaching materials to facilitate the preparation and the implementation of field activities. Each field activity is set by a group of elements to introduce the activity, a guidebook for the field activity as well as some suggestions for the guidebook resolution. At this level the aim of practical field activities is not teaching geologists but developing attitudes, procedures and basic concepts in geology that allows the understanding and interpretation of geological phenomena. The projected guidebook is characterised by a three phase model: preparation, fieldwork and synthesis- in different environments: classroom / field / classroom. The selected areas are located in the Ossa Morena Zone (Alto São Bento, Évora), West Rim (Fanhões, Montachique, Bafureira Beach and Eruptive Massif of Sintra and the surrounding region) and South Portuguese Zone (São Domingos Mine, Mértola). In the Ossa Morena Zone and the West Rim, in the selected places, will be discussed aspects related to the magmatic, metamorphic and sedimentary environments. In the South Portuguese Zone the emphasis will be on the environmental impact caused by the São Domingos Mine.
