摘要：Abstract In this paper, we present a theoretical understanding of the text on the planning of the mathematical modeling environment in the light of Basil Bernstein’s sociological theory. For such, a cross-sectional analysis of the results of three studies by the authors that depict this text in different fields was performed. In the first study, we analyze the constitution of the pedagogical text of the planning of the modeling environment by three teachers of basic education in a continuing training course on mathematical modeling. In the second and third studies, we analyzed the operation of the pedagogical text of the planning of the modeling environment in the classrooms of the three teachers participating in the course. The analysis of the data suggests that the constitution of the pedagogical text of the planning was marked by transformations that produced a proper meaning to the text, and the operationalization was manifested by transformations and resistance to them, which triggered more approximations than distances to the constituted text. The results of these studies point out how the pedagogical text of the planning of the modeling environment was constituted in the field of pedagogical recontextualization and operationalized in the field of reproduction. Thus, we retake such results and sketch that the recontextualization of this text from one field to another has generated theoretical understandings and implications for the school pedagogical practice in the field of mathematical modeling and for teacher training courses.
