Abstract

Eğim kavramı matematikte bazı konuların ön koşullarından birisidir. Kavramsallaştırma yapılabilmesi için ön koşullar önem arz etmektedir. Bu çalışmanın amacı, matematik öğretmeni adaylarının eğim kavramına ilişkin kavram bilgilerini ortaya çıkarmaktır. Araştırma Türkiye’deki bir devlet üniversitesinin matematik öğretmenliği bölümü öğrencileriyle gerçekleştirilmiştir. Öğretmen adaylarının kavram tanımlamaları, kavrama ait anlayışları incelenmiş ve sınıf seviyeleri açısından değerlendirmelerde bulunulmuştur. Elde edilen veriler incelendiğinde matematik öğretmeni adaylarının eğim kavramını daha çok geometriksel yaklaşımla ifade ettikleri, sınıf seviyesi değiştikçe eğim kavramına ilişkin bilgilerinin de değiştiği ortaya çıkmıştır. Sınıf seviyesi arttıkça trigonometrik temsilin kullanımının arttığı, fiziksel temsilin kullanımının ise azaldığı görülmüştür.
