Análise de uma situação de aprendizagem para o ensino de coordenadas cartesianas
Abstract
This dissertation has main goal analyze the Learning Situation “Cartesian coordinates and
transformations in the plane” of Material Support Curriculum of the State of São Paulo,
Student notebook, submit a proposal of a didactic sequence to the topic and check their
effectiveness. The motivation for choosing this theme came from a study made of the results
of SARESP, which present a low performance in the abilities involving this subject. The work
begins with a study of issues on Cartesian coordinates of SARESP and Brazil Test, and
official documents as PCN and Curriculum Proposal of the State of São Paulo. They are also
appreciated opinions of some researchers in the field of education on the teaching of
mathematics. We also make a brief analysis of how textbooks address the issue. Then
described the planning of the teaching sequence that includes the Student Notebook activities
as well as its application in two classes of students in Year 8. In implementing the activities
we organize students into pairs, so that they could develop problems more autonomy and less
interference from the teacher. After the implementation of the activities, students were
evaluated by a test similar to the SARESP with some questions drawn from these tests and
others built for myself. Using the results presented by the students in the activities and
evidence did an analysis of trial and error. At the end we can conclude that our work is
validated, because the students have obtained satisfactory results in the assessment, showing
that the learning situation applied in the format presented propose an appropriate outcome
compared with SARESP. To validate our research follow in big steps, the methodology
proposed by didactic engineering. This educational product is available so that teachers can
use it directly in their classes.
