On The Learning of Algebraic Language: the Teaching of literal Expressions

In this Study, I concerned the learning-teaching of the use of letters in algebra. Our Study can be summarized as follows; First, I tried to establish the theoretical Foundation necessary for the learning-teaching of the use of letters in literal expressions. Second, Imade a course of study that leads to the understanding of the meaning and the use of literals in algebraic expressions. Third, Based on this course of study, I held classes on First-grade students in middle school and I carried on an investigation their understanding of the meaning and the use of literals in algebraic expressions. Finally, I made an analysis of findings in this investigation and identified student's a better understanding of the meaning and the use of literals in algebraic expressions.
