Abstract

The concept of slope is one of the prerequisites of some topics in mathematics. Prerequisites are thought as important for conceptualization of mathematical concepts. The aim of this study is to reveal conceptual knowledge of mathematics teacher-candidates about the concept of slope. The study is conducted with the teacher-candidatesstudying at the Department of Mathematics Education in a state university in Turkey. Conceptual definitions and perceptions of the teacher-candidates about the concept were investigated and evaluated in terms of grade level. When obtained data was examined, it appeared that the teacher-candidates explained the concept with geometrical approach mostly and their knowledge level about the concept of slope differed in terms of grade level. In higher grade levels, it was found that use of trigonometrical approach increased while that of physical approach decreased

Knowledge of mathematics teacher-candidates about the concept of slope / Matematik öğretmeni adaylarının eğim kavramına ilişkin bilgileri

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.
