LIMA-DIAZ, Isaac. Perspectives of the Specialized Knowledge of Math Teachers as an Element of Their Professional Development. Rev. Fac. Cienc. Tecnol. [online]. 2017, n.42, pp.175-191. ISSN 0121-3814.

This research paper presents the theoretical contributions to the specialized knowledge of the math teacher that have been used as basic elements for professional development in the elaboration of Doctorate Thesis titled "Professional development of the math teacher: case study at the middle school level." On a first instance, the definitions of teacher knowledge and professional knowledge by Shulman (1986) and Ball, Thames and Phelps (2008) are revisited, and the change to the proposal of specialized knowledge of research by Muñoz-Catalán et al. (2015) is explained. Accordingly, the concept of professional development of the teacher is addressed and, finally, a third structure of Specialized Knowledge of the Math Teacher with three components is proposed: creation of scripts; creation of images; and creation of specific techniques. It is concluded that the knowledge of experience and reflection enable the teacher's professional development.

Palabras clave : Professional development; specialized knowledge; math teacher; math education.
