Utilizando o algeplan como recurso didático para a compreensão de expressões algébricas

Abstract

This paper is presenting the results of a survey conducted for Work Course Conclusion. The research objective was to evaluate the potential and limitations of courseware algeplan written comprehension and representation of algebraic expressions, as well as the manipulation of algebraic terms from the geometrical concept of perimeter and area of plane figures. Thus, it was conducted with a class of ninth year of Elementary School an institution of private schools, Colégio Certo, in the municipality of Rio Tinto / PB, the development of three sequences didactics through the use of manipulative teaching materials, which include content proposed. By investigating the relationship between obstacles and understanding of algebraic expressions in seeking grants to allow us to better targeting on the overall objective of this research and describe our approach used for the study of algebraic expressions, this research is characterized as an exploratory- descriptive research. The survey also is delimited within the case study for conduct a comparative analysis of the data that link the conceptual and procedural characteristics on algebraic expressions of the group of students participating in the articles used in our benchmarks. For this, the application of a Diagnostic Assessment in Initial and Final character was performed. From the examination of records obtained from the reviews, it was possible to systematize the difficulties peculiar characteristics as presented in algebraic expressions and results presented after application of didactic sequences. The findings of the research show that the algeplan included elaborate planning activities can positively contribute to the understanding of algebraic expressions, and also found some limitations in handling as well as restrictions of its parts.
