The purpose of this study is to investigate the number of extracted factors in exploratory factor analysis (EFA) studies which takes part in Turkish Measurement Tools Index (TMTI / TOAD) according to parallel analysis results. By the date the study had begun, 4440 studies were indexed in TMTI, 500 studies were selected by systematic sampling procedure among them and the number of full texts investigated is 451. For these studies, values were coded by using a form which was developed by researchers such as sample size, number of items, rotation method. For 300 studies in which EFA was implied, some of them do not include information about sample size, number of items, minimum factor loading, number of factors, extracted variance. The most frequent extraction method is principal component analysis, and criterion for number of factors is eigenvalue greater than unity. For multifactor scales typical rotation, method is varimax. Amongst 67 EFA studies that could be compared to parallel analysis results, 52 overextraction and seven underextraction situation was detected. For seven studies, number of factors were accurate. Findings are discussed within existing literature and a checklist is recommended for the purpose of minimizing deficiencies in reporting EFA results.
This study is a survey study which aims to determine underlying causes of anger and the anger levels of individuals, in the sample cases and mood-states defined in the research. 255 people participated by filling in forms developed by the researcher. They were asked to rank 6 mood-state expressions between 1 and 6, to classify 23 sample case expressions between 1 and 4. Using Microsoft Office Excel 2016, responses given to mood-state expressions were examined with rank-order and given to sample case expressions were examined with classifying judgment with respect to gender and marital status. The findings of rank-order judgment scaling revealed that all participants get angry most when they are treated unfairly and they get angry least when they are criticized. It was also found that females got angry more at being neglected, and males got angry more at arrogance and mistrust. It was concluded that married people got angry more at being neglected; unmarrieds got angry more at mistrust. The findings of classifying judgment scaling showed that all participants get angry the most when unnecessary and offending comments are made about their families. They get angry the least when their partners are fan of any subject. It also has been seen that married participants chose 'Ignoring the subjects that I care about' the most and those who are unmarried chose 'Making unnecessary and offending comments about my family' the most.
This study aims to investigate the opinions of teachers working at public, private, and International Baccalaureate (IB) Schools on the evaluation practices, the use of assessment tools, the frequency of documenting data, and the feedback frequencies given to both students, and parents. A questionnaire has been used to collect data from 168 teachers. 84 of these teachers were from public schools, 30 from IB, and 54 from private schools.Percentages and frequencies were examined to describe the data, and the chi-square test was conducted for their distribution. There are two main conclusions derived. The first one is that state schools and private schools differ from IB schools in terms of exam-oriented preparation and evaluations when traditional methods are employed. The second one is that IB schools differ from state schools and private schools in terms of documenting the data and reporting of assessment for learning improvement and process-based evaluation. In terms of teachers` opinions, the ones from the IB schools believed there was a difference in terms of having an assessment policy, collaborative planning processes with partners, and experts, taking into consideration the individual differences, and having an inspection mechanism to monitor of the processes.
The present study aims to compare the Kernel equating and Kernel local equating methods in observed score equating. Functions and error estimates regarding the difference between raw and equated scores and the scores equated by Stocking-Lord and Haebara true-score equating methods in Kernel local equating and Kernel equating were examined in Item Response Theory Observed Score Equating. Therefore, 5, 10, and 15 external anchor items were used, and scores were obtained from two forms based on the 2PL model. R (version 3.5.3.) programming software was used for IRT assumptions, item parameters, calibration, and equating analyses. The results revealed that Stocking-Lord and Haebara true-score equating methods yielded similar results. Moreover, if the equating method is the same, estimation errors decreased when the number of anchor items increased. The mean scores obtained by Kernel equation 5 and 15 anchor items were lower than Kernel local equating, while means of Kernel equating of 10 anchor items were higher. As the number of items increased, estimation errors decreased, and Kernel local equating revealed the lowest errors in the medium score scale. Kernel equating can be used based on the related ability level if the individual's ability distribution is known.
This study aims to develop a scale that will determine the factors causing professional obsolescence in the field of education. In this context, the Professional Obsolescence Scale (POS) has been developed to determine the professional and organizational obsolescence of primary, secondary and high school administrators. In this scale development process, steps were followed in line with the suggestions of Crocker and Algina (2006) and Cronbach (1984). Firstly, 63 items were prepared and 991 school principals participated the study. R (version 4.0.1) software was used to analyze the data. Item and test parameters and information functions have been estimated using Samejima's Graded Response Model based on Item Response Theory. Principal Axis Analysis was performed for the construct validity of the scale, and four-dimensions structure with 47 items has been obtained. These dimensions are named as "Being Open to Professional Development", "Job-Ability Harmony in Profession", "Organizational Support in Professional Development", "Professional Burnout". The scores obtained from each dimension are evaluated within themselves. It has been observed that each dimension fulfills the conditions of unidimensionality, local independence, model-data fit and parameter invariance. According to the Classical Test Theory, Cronbach Alpha coefficients are between 0.807 and 0.945. The Stratified Alpha coefficient calculated for the whole scale is 0.94. According to the Item Response Theory, the marginal reliability coefficients were between 0.857 and 0.936 and the empirical reliability coefficients were found between 0.854 and 0.938.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
