What else can you say about theory and practice? Or: how can it still be told? Or: can it still be told?: An essay on theory and practice in mathematics education

Abstract

This essay is a narrative about a mathematics teacher in dealing with the task of researching in mathematics education, encountering his own identity tensions, dialoguing with himself and also with a Teacher, subject of his later master's research. The narrative exposes a critique of the research’s role, especially that whose object is the teacher`s practice and knowledge, establishing a relation between the role of theory in mathematics education and the work of mathematics teachers in the classroom. Thus, treating criticism also as a matter of its own constitution as teacher and researcher, the narrative mixes fiction and reality to show a way of dealing and being, regarding this false dichotomy between theory and practice in mathematics education.
