Bugüne kadar yapılan çalışmalar çoğunlukla öğrencilerin doğal sayıları nasıl anladıklarını incelemiş fakat öğretmen adaylarının doğal sayıları nasıl anladıkları ve öğrettikleri üzerine yeterince yoğunlaşmamıştır. Bu çalışmada öğretmen adaylarının doğal sayılar kavramını ve  doğal sayılardaki işlemleri nasıl anladığını araştırmak için bir durum çalışması yapılmıştır. Çalışmada ilköğretim matematik eğitimi bölümünde okuyan öğretmen adayları, 4. sınıf zorunlu ders kapsamında doğal sayılar ve doğal sayılar üzerindeki işlemleri onluk taban yerine sekizlik tabanda hazırlanan içerik ile işlemiştir. Böylece öğretmen adaylarına onluk tabanda ezbere yaptığı birçok işlem için stratejiler geliştirme fırsatı verilmiş ve bu süreçte nasıl düşündükleri detaylı olarak araştırılmıştır. Araştırmanın sonucu farklı bir taban kullanmanın öğretmen adaylarının düşünce şeklini değiştirdiğini, ezberden çıkarak farklı bir bakış açısıyla soruları yorumladıklarını göstermektedir


Anahtar kelimeler


doğal sayılar, öğretmen adayları, sekizlik taban, dört işlem
