Functional approach to basic mathematical concepts in junior high school

Abstract

The aim of this study is twofold: First to describe an introductory course to algebra for 13-year old students which was designed in order to enhance their problem solving abilities and which partly was based on the functional approach. This course was implemented and tested in the real conditions of the classroom. Second to present the impact of this course concentrating on one student, considering him as a representative of a students’ sample and widening the conclusions, to some extent, for the majority of the students. The evidence showed that the students were able to use the graphic, table and letter-symbolic representations not only to solve all the problems in an introductory algebra level but also to form the associate equations and find their solution from their graphic representations. We also have evidence that the possibility of the extension of our approach to the solution of abstract equation demands a process of abstraction. For this reason we propose that this extensio ...
