This article is a summary of research carried out on Spanish secondary school students 14 -16 years of age, with the intention of finding out what contributions fieldwork makes toward the understanding of concepts and principles of ecology, and also to ascertain the effects of fieldwork on the defense of the studied ecosystem. Before further research was conducted, an exploratory study was carried out consisting of an initial diagnosis of the pupils' ideas; fieldwork materials were prepared and an ecology unit for the study of a freshwater ecosystem was designed, along with evaluation instruments. The experimental design was given shape thanks to work done with two groups of students on whom a more exhaustive study was performed. The independent variable consisted of a field trip; the dependent variable was the learning of ecological concepts and their application to the assessment of an environmental problem. The study combined qualitative and quantitative research methods. A result of the research work was the conclusion that fieldwork helps clarify ecological concepts and intervenes directly in the development of more favorable attitudes toward the defense of the ecosystem. Both components are seen when making valid judgments for the resolution of problems which negatively affect the ecosystem and for showing the way toward the type of actions and solutions which should be adopted.

In this article we study the repercussion that studies on ecology may have on environmental education. To do so, we review the student's alternative ideas about concepts and principles of ecology selected for the study of the subject. We stress the idea that outings to the countryside to study a specific ecosystem helps to clarify the interactions between the living things and the environment. Finally, we give the data of a research performed with high school students, supporting the idea that those students who carry out work in the countryside are able to define a larger number of components and relationships. Such training favours the transfer of ecology knowledge, both in the evaluation of an environmental problem and in proposing solutions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
