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?

Matematiksel Doyum Ölçeğinin (MDÖ) Geliştirilmesi: Geçerlik ve Güvenirlik Çalışması
2020

Abstract:

Bu çalışmanın amacı öğrencilerin matematiksel doyum düzeylerini belirlemeye yönelik geçerli ve güvenirli bir ölçme aracı geliştirmektir. Araştırma 2018-2019 eğitim-öğretim yılında toplam 763 öğrenciden oluşan üç ayrı çalışma grubu ile yapılmıştır. Ölçeğin kapsam ve görünüş geçerliği için uzman görüşü alınmıştır. Yapı geçerliği için Açımlayıcı Faktör Analizi (AFA) ve Doğrulayıcı Faktör Analizi (DFA) uygulanmıştır. AFA sonucunda toplam varyansın %59.10’unu açıklayan 19 madde ve üç faktörden oluşan bir yapı elde edilmiştir. Ortaya çıkan faktörler: Ders Etkileşim Doyumu, Kişisel Etkileşim Doyumu ile Çevresel Etkileşim Doyumu olarak adlandırılmıştır. DFA sonucunda Matematiksel Doyum Ölçeğine (MDÖ) ilişkin 19 madde ve üç faktörlü yapının yeterli uyum indekslerine sahip olduğu belirlenmiştir (χ2/df=1.96 RMSEA=.06 SRMR=.07 CFI=.95 NFI=.91 IFI=.95 GFI=.89 AGFI=.86 PNFI=.77 PCFI=.81). Ölçeğin toplam iç tutarlık katsayısı .95 ders etkileşim, kişisel etkileşim ile çevresel etkileşim doyumlarının iç tutarlık katsayıları sırasıyla .93, .88 ve .82 olarak hesaplanmıştır. Ölçekteki maddelerin ayırt ediciliği düzeltilmiş madde toplam korelasyonu ile %27’lik alt-üst grup karşılaştırmaları ile yapılmış ve maddelerin tamamının ayırt edici olduğu belirlenmiştir. Ölçüt geçerliği sonucunda aracın amacına hizmet ettiği belirlenmiştir. Sonuç olarak, elde edilen bulgular MDÖ’nün geçerli ve güvenilir ölçümler üreten bir ölçme aracı olduğunu göstermektedir

Development of the Mathematical Doyum Scale (MDÖ): Validity and Trust Study
2020
Author:  
Abstract:

The aim of this study is to develop a valid and reliable measurement tool to determine students’ mathematical satisfaction levels. The study was conducted with three separate study groups consisting of a total of 763 students in the 2018-2019 educational year. Expert opinion has been taken for the scope and validity of the scale. For the validity of the structure, the Opening Factor Analysis (AFA) and the Verifying Factor Analysis (DFA) were applied. The AFA resulted in a structure consisting of 19 substances and three factors that described 59.10% of the total variance. Factors that appear: The lesson interaction is called the personal interaction and the environmental interaction. The result of the DFA has been determined that 19 matters and three-factor structures related to the Mathematical Doyum Scale (MDÖ) have sufficient conformity indicators (χ2/df=1.96; RMSEA=.06; SRMR=.07; CFI=.95; NFI=.91; IFI=.95; GFI=.89; AGFI=.86; PNFI=.77; PCFI=.81). The total internal consistency ratio of the scale is .95; the internal consistency ratio of course interaction, personal interaction and environmental interaction satisfaction is calculated as .93, .88 and .82, respectively. The distinctivity of the substances in the scale was made by comparisons of 27% of the sub-top group with the corrected total correlation of the substance, and the whole substance was determined to be distinctive. The measurement validity is determined to serve the vehicle for its purpose. As a result, the findings obtained indicate that MDÖ is a measurement tool that produces valid and reliable measurements.

Abstract:

The aim of this study is to develop a valid and reliable measurement tool to determine the mathematical satisfaction levels of students. The research was conducted with three separate study groups consisting of 763 students in the academic year of 2018-2019. Expert opinion was obtained for the content and face validity of the scale. Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) was applied for construct validity. As a result of EFA, 19 items and three factors explaining 59.10% of total variance were obtained. The factors that emerged were named as the Course Interaction Satisfaction, Personal Interaction Satisfaction, and Environmental Interaction Satisfaction. Findings from CFA; 19 items and three-factor structure related to Mathematical Satisfaction Scale (MSS) showed that they have adequate fit indices (χ2/df=1.96; RMSEA=.06; SRMR=.07; CFI=.95; NFI=.91; IFI=.95; GFI=.89; AGFI=.86; PNFI=.77; PCFI=.81). The total internal consistency coefficient of the scale was .95; the internal consistency coefficients of course interaction, personal interaction and environmental interaction satisfaction were calculated respectively .93, .88 and .82. The discriminate of the items in the scale was made with the corrected item-total correlation and the 27% lower and upper group comparisons and all of the items in the scale were distinguishable. The result of criterion validity showed that the tool served its purpose.  As a result, the findings show that a mathematical satisfaction scale is a measurement tool that produces valid and reliable measurements.
