The purpose of study is to examine the reliability of analytical rubrics and checklists developed for the assessment of story writing skills by means of generalizability theory. The study group consisted of 52 students attending the 5th grade at primary school and 20 raters in Mersin University. The G study was carried out with the fully crossed hxpxg (story x rater x performance task) design, where the scoring keys were determined as fix facet. Decision Study was carried out by changing the task facet conditions. As a result, it was observed in both scoring keys that the sources of variance related to the stories had a high variance percentage in the main effects while "hp (story and rater interaction effects)" a high variance percentage in the interaction effects. The highest variance in the design belongs to the interaction effect "hpg (story, rater and performance task interaction effects)". This can be an indicator for the existence of different sources of variability and error, which are not included in the design. Examining the G and phi coefficients calculated for both scoring keys, it was determined that scoring with analytic rubrics is more reliable and generalizable. According to the decision studies, it was decided that the number of tasks used in this study is to be most appropriate.

Hesaplanan kapsam geçerlik oranı ve kapsam geçerlik indeksleri sonucunda ölçek deneme formunda 49 madde yer almasına karar verilmiş ve ölçek çevrimiçi ortamda öğretmen ve öğretim elemanlarının gönüllü olarak cevaplamalarına sunulmuştur. 316 veri ile gerçekleştirilen açımlayıcı faktör analizi sonucunda ölçeğin iki bileşen altında gruplanan ve toplam 25 madde ile temsil edilen yapısına karar verilmiştir. Ölçeğin karar verilen yapısının sınanması amacıyla 202 veri üzerinden doğrulayıcı faktör analizi gerçekleştirilmiştir. Gerçekleştirilen doğrulayıcı faktör analizi sonucunda maddelere ilişkin standartlaştırılmış yük değerlerinin 0,43 ile 0,87 arasında değişkenlik gösterdiği, tüm t değerlerinin istatistiksel olarak anlamlı olduğu ve hesaplanan uyum indekslerinin de mükemmel/kabul edilebilir düzeyde olduğu görülmüştür. Ölçeğin açıkladığı toplam varyans oranı %65,895 ve ölçeğe ilişkin hesaplanan Cronbach Alpha güvenirlik katsayısı 0,958 ve McDonald Omega katsayısı ise 0,962'dir. Ayrıca alt faktörlere ilişkin hesaplanan birleştirici güvenirlik katsayısının sırasıyla 0,95 ve 0,93; yakınsak geçerliğin 0,611 ve 0,537 olduğu ve ıraksak geçerliğin de her iki faktör için de sağlandığı görülmüştür. Elde edilen bulgular geliştirilen ölçeğin bilimsel ve psikometrik açıdan geçerli ve güvenilir bir ölçme aracı olduğunu göstermektedir.
The goal of this study is to determine the reliability of the performance points of dentistry students regarding communication skills and to examine the scoring reliability by generalizability theory in balanced random and fixed facet (mixed design) data, considering also the interactions of student, rater and duty. The study group of the research consists of the 16 dentistry students who took communication skills elective course in Hacettepe University in 2014-2015 academic year. In the study, the variability sources are taken as student (s), rater (r), occupation (o) and task (t). 16 students are assigned with 16 different duties and whether the students fulfill the duties is rated by 8 raters from two different occupation groups, 4 standard patients and 4 academicians. On these facets using different designs G study has been performed. Within the scope of this study the sxrxt design where all variability sources are crossed; sx(o:r)xt design where the occupation nested on rater as the result of scoring of the students by two different occupation groups as standard patient and academicians; sxaxt and sxspxt facets where rater facet is taken as fixed facet according to occupation groups (sp: Standard Patient, a: Academician) were examined. For each design estimated variance components are discussed separately.
Background: Within the 3Cs (closeness, commitment, and complementarity) theoretical framework of the quality of two-person relationships, a coach–athlete relationship quality questionnaire (CART-Q) was developed and validated to assess the nature of the coach–athlete relationship. In this study, a modified version of the CART-Q for physical education (PE) was adapted to assess the teacher–student relationship quality in the PE context in Turkey and Kuwait. The purpose of this study was to examine the factorial validity of the teacher–student relationship quality questionnaire (TSRQ-PE) within a sample of Turkish and Kuwaiti physical education teachers. Methods: Multigroup confirmatory factor analysis (MGCFA) was used to test the measurement of cultural invariance between these two groups. A total of 175 teachers from Turkey (n = 73) and Kuwait (n = 102) completed the TPRQ-PE. Results: MGCFA supported the factorial validity of the TPRQ-PE in a three first-order factor model across the two countries. Overall, these results add evidence to the psychometric properties of the TPRQ-PE and suggest that this instrument can be applied to measure the quality of the teacher–student relationship within Turkey and Kuwait, although caution may be required when applied to drawing comparisons between these two counties. Conclusions: The results of the present study could help physical educators and researchers in this field to understand the reasons and methods that lead to a quality teacher–student relationship.

The aim of this study is to develop a reliable and valid scale tool that measures social media jealousy in romantic relationships of individuals who have had and are currently living in a romantic relationship. For this purpose, in the process of creating a candidate scale form; "qualitative steps" (focus group interviews, essay printing, literature scale scanning) and "quantitative steps" (validity and reliability analysis) were used. Items with content validity rate below .80 after expert evaluations were removed from the 57-item form and 53 items remained. The 53-item and five-point likert-type trial scale form was applied to 417 individuals between the ages of 18-56 who had or had a romantic relationship. The basic assumptions of Explanatory Factor Analysis (EFA) have been tested; As a result of EFA, a structure consisting of a total of 21 3-dimensional items, namely "Restrictive and Controlling Attitude", "Skeptical and Observant Attitude", and "Respect and Trust in the Field of Social Media", was obtained. In order to examine the psychological construct validity of Social Media Jealousy in Romantic Relationships Scale; With the final form consisting of 21 items formed after EFA, data were collected again with 332 individuals; Before CFA, assumptions were tested and confirmatory factor analysis (CFA) was performed. As a result of DFA; When the standardized load values of the sub-dimensions, the estimated error variances for the variables, the T values of all items and the goodness of fit of the model were examined, it was found that the 3-factor structure of the scale consisting of 21 items was confirmed as a model. When the convergent validity, divergent validity and combining reliability values of the scale after CFA are examined, it is seen that the values are suitable for the criteria in general. Finally; Cronbach alpha internal consistency coefficient; .922 for the whole scale, .878 for "Restrictive and Controlling Attitude", .881 for "Skeptical and Observant Attitude", and .878 for "Respect and Trust in Social Media". When all these findings are examined; It was concluded that it is a reliable and valid scale for measuring social media jealousy in romantic relationships.
