PROFESSIONAL KNOWLEDGE OF FUTURE PROFESSORS OF MATHEMATICS ON THE PROPERTIES OF EQUALITY: AN EXPERIMENT TRAINING MEDIATED BY PROFESSIONAL LEARNING TASKS

MTSK. Professional knowledge. Mathematics teacher's initial training.
Professional learning. TAP. Equality properties.

In this research, we seek to analyze the professional knowledge of future mathematics
teachers about the content and teaching of the properties of equality for the 6th year of
Elementary School. It is a qualitative and interpretative investigation along the lines of an
intervention research. As a theoretical framework, we base ourselves on the Mathematics
Teacher's Specialized Knowledge (MTSK), which assumes that the professional knowledge of
the mathematics teacher is specialized (CARRILO et al., 2014). This model was also used for
the analysis of descriptive data as it is an analytical and interpretive instrument. Data production
took place through a training experiment mediated by a Professional Learning Task (TAP) and
orchestrated by the Professional Learning Opportunities (OAP) model, whose acronym in the
English language is PLOT (Professional Learning Opportunities for Teachers), from the
perspective of Ribeiro and Ponte (2020). The data come from audio recordings, written records
and discursive interactions that took place during the training period, in which six
undergraduate students who were studying the Mandatory Supervised Internship III (ESO III)
discipline at a public university located in the state of Pernambuco and also the subject teacher
(training teacher). The results showed evidence that undergraduates have, with regard to the
properties of equality, knowledge of mathematical content (KoT), knowledge of teaching
mathematics (KMT) and knowledge of learning patterns (KMLS), and that, through interactions
discursive and the mediation of the trainer teacher, revealed to improve this knowledge.
