MATEMAİK İNANCI ÖLÇEĞİ: YAPI GEÇERLİĞİ VE GÜVENİRLİK ANALİZLERİ

Bu çalışmada, ortaokul öğrencilerinin matematik inancını ölçen Matematik İnancı Ölçeği‟nin geçerlik ve güvenirliğini sınamak amaçlanmıştır. 250 ortaokul öğrencisinden elde edilen verilerle taslak ölçeğin madde ayırt ediciliği, yapı geçerliği (açımlayıcı ve doğrulayıcı faktör analizi) ve iç tutarlıkları araştırılmıştır. Bulgular; Matematik İnancı Ölçeği‟nin (i) Faydalılık, (ii) Kaygı, (iii) Çaba ve (iv) Sınırlılık olmak üzere dört faktörden oluştuğunu, geçerli ve güvenilir olduğunu göstermiştir. Sonuç olarak, Matematik İnancı Ölçeği‟nin ortaokul öğrencilerinin matematik inançları araştırılmalarında kullanılması için yeterli kanıtların olduğu söylenebilir.

MATHEMATICS BELIEF SCALE: CONSTRUCT VALIDITY AND RELIABILITY ANALYZES

In this study, it was aimed to test the reliability and validity of the Mathematics Belief Scale, which measures mathematics beliefs of middle school students. The data obtained from 250 secondary school students were investigated for item scale, construct validity (exploratory and confirmatory factor analysis) and internal consistency of the draft scale. Findings; The Mathematics Belief Scale has shown that it consists of four factors: (i) Benefit, (ii) Anxiety, (iii) Effort and (iv) Limitation, and it is valid and reliable. As a result, it can be said that there is sufficient evidence to use the Mathematics Belief Scale for the research of mathematics beliefs of middle school students.
