The present work is the result from the developed project in the year of 2011, at "Escola Municipal Professora Othília Fornari de Lima" SP State, with students from the 6th grade on the primary school. On the geography contest the field activities were used as strategies for the development of the Geoscience and Environmental Education, trying to contribute for the development on the cognitive process for the students and for the improvement as a teacher-researcher. For this proposal, four field itineraries were chosen, all of them about the school. The metodological approach used in this project was the qualitative research, giving emphasis on the descritive relationships between the teacher and the students and the pedagogical practices developed in three different moments: on the prefield classes, on the classes and on the postclassses. The action research was chosen as a method to make the students and the teacher to participate with the local reality, and by this way they could set up an identification with the socioenvironmental processes in the town, leaving the teacher to act at the same time as a researcher and observer on the own work. The comprehension about the natural phenomenon and the connection relationship among these processes and the antropic actions, show according to the students as soon they have besides the theoretical classes, a practical study in and to recognize the place where they live as a live and dynamic source. By this way, the Geography subject having the field contribution as a practice teaching, gives the opening for the knowledge on an organized and with context.Then,this will give a sense of making part of this reality. Thinking about these two questions were made for the project that I tried to analyze: till when the teacher´s participation can be significant for the cognitive processes from the students; on a second hand how the field practices can make possible a better comprehension on the antropic impact actions about the dynamic and the natural processes that change the landscape dynamically; The application of conception maps in activities pre and post field, gave area for the analysis from the previous knowledge comparing to the learned and developed subjects. The system area for the analysis about the students production added four categories: conception maps, pictures, maps representation and text produtions.
