摘要：AbstractAlgebraic expressions and linear equations are a vital part of the secondary school mathematics. A substantial amount of research has shown that students have some difficulties recognizing the structure of both of these concepts. In this study, it is analyzing the students’ understanding of the differences and similarities between algebraic expressions and linear equations. For this purpose, six eighth grade students were interviewed and observed as they worked with various mathematical tasks relating to algebraic expressions and linear equations. The data collected in this study showed that these students simplified algebraic expressions and solved linear equations with one unknown, arriving at the correct result. But, they still had difficulties indicating a relation between algebraic expressions and linear equations.
