So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.
How can I see only citations to my article?
After searching the name of your article, you can see the references to the article you selected as soon as you click on the details section.

Abstract:

Bu çalışmanın amacı öğretmen adaylarının bilim tarihine ve bilim tarihini derslerinde kullanmalarına yönelik tutumlarını ortaya çıkaracak bir ölçek geliştirmektir. Bu amaç doğrultusunda ilgili alan yazın taranarak madde havuzu oluşturulmuş ve bu madde havuzunda yer alan maddelerin kapsam geçerliğinin sağlanması için uzman görüşüne başvurulmuştur. Araştırma, geliştirilen ölçeğin ön formu ve son formu iki ayrı örneklem üzerinde uygulanmıştır. Ölçeğin ön formu uygulandığı 183 öğretmen adayına uygulanmıştır. Ölçeğin ön formunun yapı geçerliği için Açımlayıcı Faktör Analizi uygulanmıştır. Ölçeğin güvenirliğine ilişkin Cronbach alfa iç tutarlık katsayısına bakılmış, üst %27 ile alt %27 grupların madde ortalamaları arasındaki farkların anlamlılığı incelenmiş ve faktörler arasında anlamlı bir ilişki bulunup bulunmadığını belirlemek amacıyla Pearson çarpım moment korelasyonları hesaplanmıştır. Çalışmanın ikinci aşamasında geliştirilen ölçeğin son formu 113 öğretmen adayına uygulanmış ve elde edilen verilerle yapı geçerliği için Doğrulayıcı Faktör Analizi yapılmış; güvenirlik çalışması için Cronbach alfa iç tutarlık katsayısı, faktörler arasında anlamlı bir ilişki bulunup bulunmadığını belirlemek amacıyla da pearson çarpım moment korelasyonları hesaplanmıştır. İki aşamalı gerçekleştirilen bu ölçek geliştirme çalışmasının sonucunda beşli likert tipte, 29 maddeden oluşan ve 3 faktörlü Bilim Tarihi Tutum Ölçeği geliştirilmiştir. Ölçeğin geneli için Cronbach alfa iç tutarlık katsayısı 0.95; Bilim Tarihi Yönteminin Öğrenmeye Katkısı (Faktör 1) için 0.93, Bilim Tarihi İlgi (Faktör 2) için 0.92 ve Bir Öğretim Yöntemi Olarak Bilim Tarihi (Faktör 3) için 0.85 olarak hesaplanmıştır. Tüm analizler sonucunda Bilim Tarihi Tutum Ölçeği’nin öğretmen adaylarının bilim tarihine ve bilim tarihini derslerinde kullanmalarına yönelik tutumlarının ortaya çıkarılmasında kullanılabilecek geçerli ve güvenilir bir ölçme aracı olduğu saptanmıştır.

Science History Attitude Scale: Development, Validity and Trust Study
2020
Author:  
Abstract:

The aim of this study is to develop a valid and reliable scale to identify attitudes of teacher candidates towards the history of science and using the history of science as a teaching method in their classes. For this purpose, the related field literature was searched and item pool was created. Following that, items in the item pool were sent to five experts to ensure the content validity. The pre-form and final-form of the developed scale were administered two different samples. The pre-form of the scale was administered to 183 pre-service teachers. The construct validity of the pre-form of the scale was examined with Exploratory Factor Analysis. Additionally, Cronbach alpha correlation coefficients, t-tests between items' means of upper 27%-lower 27% points and Pearson product moment correlations were calculated. The second stage of the study was carried out with 113 pre-service teachers in order to perform the confirmatory factor analysis of the final form of the scale. The construct validity of the final form of the scale was examined through Confirmatory Factor Analysis and the reliability was calculated through Cronbach alpha correlation coefficients and Pearson product moment correlations. As a result, the History of Science Attitude Scale, a 5-point Likert-type attitude scale consisted of three subscales with 29 items was developed. Cronbach alpha coefficient of the whole scale is 0.95. Internal consistency coefficients for the sub-scales varied between 0.85 and 0.93 and found to be within admissible limits. In the light of the results, it could be argued that the History of Science Attitude Scale is valid and reliable instrument and can be used in identifying attitudes of teacher candidates towards the history of science and using the history of science as a teaching method in their classes.
