Abstract

Bu araştırmanın amacı, öğretmen adaylarının
birinci dereceden iki bilinmeyenli denklem sistemlerini yorumlarken ilgili
kavramsal anlamalarını ve ne tür güçlükler yaşadıklarını incelemektir.
Araştırmaya, Türkiye’de büyükşehirdeki bir devlet üniversitesinin 3. sınıfında
okuyan 162 sınıf öğretmeni adayı katılmıştır. Öğretmen adaylarından, 2x-3y=19 ……………………………………………….
                                                                                                                                                                                                                     3x+6y=18
denklem sistemi ile çözülebilen bir gerçek yaşam problemi yazmaları
istenmiştir. Böylece, yazdıkları problemlerle, öğretmen adaylarının denklem
sistemini nasıl analiz ettiklerini ve sistemdeki kavramları nasıl ele
aldıklarını ortaya çıkarmak amaçlanmıştır. Sonuç olarak; öğretmen adaylarının,
birinci dereceden iki bilinmeyenli denklem sistemlerini yorumlamada ve ilgili
kavramları anlamlandırmada güçlük yaşadıkları ve bu kavramlarla ilgili önemli
eksikliklerinin olduğu belirlenmiştir.
