Enerji Okuryazarlığı Ölçeğinin Türkçeye Uyarlanması: Geçerlilik ve Güvenilirlik Çalışması

Bu araştırmanın amacı DeWaters, Qaqish, Graham ve Powers (2013) tarafından geliştirilen “Enerji Okuryazarlığı Ölçeği”ni Türkçeye uyarlamak ve ölçeğin Türkçe formunun geçerlilik ve güvenilirliğini sağlamaktır. Bu amaç doğrultusunda, ölçek maddeleri önce Türkçeye çevrilmiş, sonra maddelerin İngilizceye geri çevrilmesi yapılmıştır. Bir sonraki aşamada ise çeviriler arasındaki tutarlılık incelenmiş, anlam kaybı ya da değişiklikler kontrol edilmiştir. Yapılan işlemler İngiliz Dili Eğitimi öğretim elemanları tarafından değerlendirmeye tabi tutularak, soruların anlaşılırlığı, kelime ve cümle yapıları ile kültürel uygunluğu gözden geçirilmiş ve ölçeğe son hali verilmiştir. Ölçeğin geçerlilik ve güvenilirliğinin sağlanması amacıyla ölçek Muğla ili merkez ortaokullarındaki 550 öğrenciye uygulanarak çeşitli analizler yapılmıştır. İlk olarak ölçeğin yapı geçerliliğini sağlamak için açımlayıcı faktör analizi (AFA) yapılmıştır. Sonrasında AFA’dan elde edilen madde-faktör yapısının model uyumu doğrulayıcı faktör analizi (DFA) ile test edilmiştir. Son olarak ise ölçeğin güvenilirlik çalışmaları kapsamında ölçeğin genelinin ve her bir faktörün (bilişsel boyutta KR-20) Cronbach-Alpha güvenilirlik katsayısı hesaplanmıştır. Araştırma sonucunda ölçeğin bilişsel, duyuşsal ve davranışsal olmak üzere 3 boyutu kapsadığı tespit edilmiştir. Ayrıca ölçekteki her bir boyuta yönelik iç tutarlılık katsayısının .72 ve .82 arasında değiştiği, tüm ölçeğe ait değerin ise .83 olduğu belirlenmiştir. Bu doğrultuda ortaokul öğrencilerinin enerji eğitimine ilişkin enerji okuryazarlıklarının değerlendirilebileceği geçerli ve güvenilir bir ölçek geliştirilmiştir.

Adaptation of the Energy Literacy Scale into Turkish: A Validity and Reliability Study

The purpose of the current study was to adapt the “Energy Literacy Scale” developed by DeWaters, Qaqish, Graham and Powers (2013) into Turkish and to ensure its reliability and validity for the Turkish context. The items were first translated into Turkish and then back translated into English. In the next stage, the consistency between the translations was checked to analyze any missing in meaning. English lecturer evaluated items’ comprehensibility levels, word and sentence structures and cultural compliance level. The scale was administered to 550 students from middle schools in the city of Muğla. Then, Exploratory Factor Analysis (EFA) was firstly conducted to establish the construct validity of the scale. Later, to test the model fit of the item-factor structure obtained from EFA, Confirmatory Factor Analysis (CFA) was run. Finally, Cronbach Alpha reliability coefficient was calculated for the whole scale and for each factor. The results appeared a three-factor scale (cognitive, affective and behavioral). Moreover, the internal consistency coefficients for each factor ranged from .72 to .82 as well as the coefficient for the whole scale was found to be .83. Overall, a valid and reliable scale was developed to evaluate secondary school students’ energy literacy levels of energy education.
