For a Possible Configuration of the Professional Knowledge of the Mathematics Teacher Educator: a Comparative Analysis

Abstract This paper reviews and gathers some of the most relevant contributions regarding the problem raised by the conceptualization of the nature and organization of the mathematics teacher educator’s professional knowledge, a great challenge for the research community in mathematics education. Through a search in the Web of Science database and after a first selection of scientific research, we expose the theoretical foundations of three different models of MTE’s knowledge: the extended triad, the MKTT, and the model of Escudero-Ávila, Montes y Contreras (2021), to subsequently, carry out a comparative analysis. The conclusions point towards a meta-knowledge of a complex nature which allows articulating three nested levels – mathematical task, students, and teacher – as well as its specificity, with subdomains which are specific and exclusive to the MTE, although we observe a notable emphasis and interest on the mathematical content knowledge and pedagogical content knowledge.
