Analysis of the Relationship between Geometrical and Algebraic Thinking Levels of 8th Grade Students

This research aims to analyze the relationship between geometrical and algebraic thinking levels of 8th grade students. for this purpose survey method was used in the study. the participants of the study consist of 515 students from eight different schools in diyarbakır city central districts during 2010-2011 education year spring semester. in present research geometric thinking test developed by usiskin (1982) and was adapted to turkish by duatepe (2000) has been employed to detect geometric thinking levels of students. in determining algebraic thinking levels of students algebraic thinking test developed hart vd. (1998) and was adapted to turkish by altun (2005) was used. according to the results obtained from the study, it is determined that 8th grade students focus level-1 (visual level) in terms of geometric thinking levels and level-0 in terms of algebraic thinking levels. it was determined that, gender is not an effective variable on students’ geometric and algebraic thinking levels. in this research it has also been pointed out that positive, moderate and significant relationship between geometrical and algebraic thinking levels of students.
