Abstract

In this study, it was aimed to examine the concept of triangle in middle school mathematics
textbooks (grades 5-8) in terms of tool/object dialectic and to examine in which case the concept
has the status of tool and in which case it has the status of object from the 5th to the 8th grade level.
Since the textbooks were analyzed in the study, this study is a document analysis study. The MoNE
5th, 6th, 7th, and 8th grade textbooks taught in middle schools in the 2022-2023 academic year
were used as documents in the study. The triangle concept in the textbooks was examined in terms
of the tool/object dialectic, and the situations in which the concept is related to the status of tool or
object were analyzed using document analysis. As a result of the research, it has been reached that
the concept of middle school mathematics 5th grade lesson triangle is mostly in the "object" status,
while it is mostly in the "tool" status in the 6th, 7th and 8th grade textbooks. Therefore, it can be
interpreted that there are limits to basic learning about triangles in the 5th grade, and that more
emphasis should be placed on triangles in the 6th, 7th and 8th grades.
