We present, in these writings, an interdisciplinary proposal with the objective of analyzing the students’praxeologies of the 1st year of “Ensino Médio”, in “linear function" including the disciplines mathematics, chemistry and physics. In order to do so, we propose the creation of a space that provides an environment where this practice can be practiced. The study of this theme has ecology predicted for the 9th grade of elementary school II and also works as a tool for other ecologies in other institutions. This work is inserted in the field of didactic mathematics and uses contributions from the anthropological theory of Didactics, elaborated by Chevallard, a framework that provides us with valuable tools to understand the state of the institution. We use the notions of personal and institutional relations and praxeology, based on the research methodology adopted in this work, as well as the dialectic of the ostensives and non-ostensives, which serve as an important instrument for the analyses of Mathematical activities proposed in textbooks, besides teachers ' praxeologies and student production. In a qualitative research line, supported by the engineering of the study and research course, we support this work in the proposals of authors who discuss the theme of interdisciplinarity, (Fazenda, Gusdorf, Japiassu, Lenoir, Philippi Jr and Fernandes, Castile, Romo Vázquez, among others), which serve as foundations to meet the interests of reflection on interdisciplinary action. To analyze the effects of this work, we built a study and research course (PEP) capable of revealing the relationships between the subjects and the mathematical knowledge. We believe that the practice of interdisciplinarity can be seen as a guiding principle for the reorganization and articulation of the students ' know-how in acquiring interdisciplinary knowledge about the linear function, from the construction or Reconstruction of new praxeologies, through tasks, techniques associated with a theory, and technologies as proposed by the anthropological theory of didactic. We hope to contribute significantly to the development of interdisciplinary practices in the students’ learning process, providing new ways of acquiring knowledge, since Interdisciplinarity searches for Integration of the knowledge of the disciplines involved in the solution of a particular complex problem.
