Abstract

Bu araştırmanın amacı, ortaokul matematik
öğretmeni adaylarının cebirsel ifade ve denklemlere ilişkin kurdukları
problemlerin incelenerek sınıflandırılmasıdır. 
Araştırmaya ait veri 2012- 2013 bahar döneminde bir devlet
üniversitesinin ilköğretim matematik öğretmenliği programında öğrenim görmekte
olan 96 öğretmen adayından toplanmıştır. Veri toplama aracı olarak
araştırmacılar tarafından geliştirilen ve beş açık uçlu maddeden oluşan Problem
Kurma Testi kullanılmıştır. Öğretmen adaylarından verilen cebirsel ifade ve
denklemlere uygun problem kurmaları istenmiştir. Kurulan problemler betimsel
analiz yöntemine uygun olarak sınıflandırılmıştır. Yapılan analizler sonucunda,
öğretmen adaylarının cebirsel ifade ve denklemlere yönelik genel olarak sözel
ve çözülebilen problemler kurdukları, kurulan problemlerde genellikle günlük
dili kullandıkları tespit edilmiştir.

Abstract

The purpose of this study is to examine pre-service elementary mathematics teachers’ problems posed about algebraic expressions and equations. Data was collected from 96 pre-service elementary mathematics teachers in the spring semester of 2012- 2013 who were enrolled in a teacher education program at a public university.  Problem Posing Test consists 5 open ended items which were developed by researchers was used as a data collection tool. Pre-service elementary mathematics teachers were asked to pose problems corresponding to the algebraic expressions and equations. Problems were examined and classified. Descriptive statistics were used to determine pre-service elementary mathematics teachers’ problem types. Findings of the study indicated that in general problem types were classified as story and solvable problems, they used daily language for posing problems.
