AN EXAMINATION OF 7TH GRADE STUDENTS’ MISTAKES IN ALGEBRAIC EXPRESSIONS

Year 2016, Volume: 4 , 168 - 171, 01.09.2016

Abstract

The
aim of this study is to determine students’ achievement rates in algebraic
expressions and the mistakes they made. 100 7th grade students from
4 different schools in the center of Burdur attended to the research. The study
is a qualitative research, which was carried out in the survey design, and the
data was analyzed using descriptive analysis. A test that consisted of 6 open-ended
questions about algebraic expressions was used as the measurement tool. During
the development of the questions, algebra learning area of the 7th
grade was considered as the scope. A 9-question test was developed by
consulting expert and teacher opinions in the first place. This test was
applied in a 7th grade class and 2 questions were excluded as they
were not appropriate in terms of difficulty levels, and also, some questions
which caused problems in understanding were revised. The students’ achievement rate is 68% in addition operations in the
algebraic expressions, 43% in expressing a verbal expression algebraically and
26% in expressing a geometric representation as an algebraic expression. Their
overall average is 69%.  Looking
at the reasons behind the mistakes from a broader perspective, it was
determined that the main reasons were failure to attribute a meaning to the
unknown and therefore doing the operations by assigning a value to the unknown.
In other words, it could be asserted that failure to understand the main idea
of algebraic expressions (the concept of variable and the concept of algebraic
expression involving variables) as a concept properly is the major reason.
