Registros de representações semióticas em combinatória: uma pesquisa diagnóstica com estudantes de pedagogia de uma instituição pública do Pará (BR)

This study aims to analyze the records produced by Pedagogy students in Combinatorics activities, whose theoretical framework builds on Duval's Theory of Representational Records. It is diagnostic research of a descriptive and analytical kind carried out with 20 students in the fourth semester of the Pedagogy course from a Higher Education Institution in the interior of Para who answered three questionnaires with two questions each. In this research, we analyzed and discussed two of them that involved the study of Combinatorics. The data production procedures were observation, audio recording, and the recording of student's written productions in the study of Combinatorics. According to the results of the data analysis, it was possible to observe that the Pedagogy students mobilized the starting register, the natural language (statement) for the arrival registers, schematic, and numerical situation by applying the Multiplicative Principle of Counting.
