Abstract

Nowadays, it is an important issue to diagnose and provide educational support to mathematically gifted students who are seen as the potential to develop societies. Literature review and existed practices reveal that there is no common and clear way to diagnose mathematically gifted students. In this study, it was aimed to explain the adaptation studies of Test of Mathematical Abilities for Gifted Students (TOMAGS), which was developed by Ryser and Johnsen (1998) into Turkish Language. TOMAGS was a norm referenced, standardized test and in this study, steps that Hambleton (2002) proposed for adaptation of an achievement test were followed. In this regard, first of all, language and cultural adaptations were conducted and then, psychometric analysis was carried out based on the results obtained from implementation of the test with the sample consisting of 563 students whom aged ranged between 9 and 12 in different cities of Turkey. Results show validity and reliability evidences from the implementation and it was concluded that the test can also be used in Turkish Language for identifying mathematical abilities of gifted students.

Üstün Yetenekli Çocuklar için Matematiksel Yetenek Testi’nin (TOMAGS) Türkçe’ye Uyarlama Çalışması

Abstract

Günümüzde, toplumları ileriye taşıyabilecek potansiyeller olarak görülen matematikte üstün yetenekli çocukların tanılanmaları ve ihtiyaç duydukları eğitimsel desteğin sağlanabilmesi oldukça önemli bir konu olarak görülmeye başlanmıştır. Ancak var olan uygulamalar ve erişilebilen alan yazın taramaları bu çocukları tanılamak için çok yaygın ve net bir yöntem bulunmadığını ortaya koymaktadır. Bu sebeple, bu çalışmada matematikte üstün yetenekli çocukları belirlemek amacıyla geliştirilmiş olan TOMAGS (Test of Mathematical Abilities for Gifted Students)’ın Türkçe uyarlama çalışmaları süreci ve bulguları hakkında bilgi vermek amaçlanmıştır. Standardize edilmiş, norm referanslı bir test olan TOMAGS’ın Türkçe uyarlama sürecinde başarı testinin uyarlama sürecine ilişkin önerilen adımlar izlenmiştir. Bu süreçte önce dil ve kültür uyarlamaları yapılmış, ardından testin 9-12 yaş aralığındaki 563 kişiden oluşan örneklemde uygulanmasından elde edilen veriler ile psikometrik analizleri yapılmıştır. Güvenilirlik ve geçerlik kanıtları sunulan uygulama sonuçlarında ise testin Türkçe dilinde de üstün yetenekli çocukların matematiksel yeteneğin seviyelerini belirlemede kullanılabileceği sonucuna varılmıştır.
