Resumo
This master dissertation with focus in mathematics education took place within the
Graduate Education Program at Center of Education at Federal University of Espírito
Santo. Our research occurred in 2013 in a public school in the city of Vitória, ES. Our
qualitative research investigates are the 3
rd grade Elementary School students
strategies and ideas about division. In addition, we conducted a teaching experiment
in the classroom working with some activities that explored the concept of division. We
answered the following questions: Which strategies and ideas about division the 3rd
grade (4th year) Elementary School students show before and after a formal teaching
experiment about division? The studies of Gómez Chacón, Lorenzato, Polya, Santos,
Santos-Wagner, Selva, Serrazina, e Vigotsky, among others, offered theoretical
contributions to this work. We collected data through lessons observed, activities
solved by students and classes taught by the beginner researcher teacher. The
analysis procedures occurred under the light of the cited authors. Students were
encouraged to establish relationships, conjecture and argue about their conclusions
throughout the educational tasks. The experience with these activities contributed to a
change of students’ attitudes, leading them to become more reflective and active in
math classes. Furthermore, we believe that changes with respect to division’s
conceptions and division’s teaching strategies occurred with both the classroom
teacher and the beginner teacher researcher. We, also, observed the development of
students' autonomy in seeking new mathematics learning situations and strategies to
solve and elaborate problems. We hope this research will inspire other teachers to
develop pedagogical practices that prioritizes the construction of the concepts in match
and the usage of their own strategies. We dream that the teachers feel that it is
important to consider peculiarities, particularities and abilities of all the ones who are
mathematics and learning process.
