This article considers potential problems that can arise in estimating a unidimensional item response theory (IRT) model when some test items are multidimensional (i.e., show a complex factorial structure). More specifically, this study examines (1) the consequences of model misfit on IRT item parameter estimates due to unintended minor item‐level multidimensionality, and (2) whether a Projection IRT model can provide a useful remedy. A real‐data example is used to illustrate the problem and also is used as a base model for a simulation study. The results suggest that ignoring item‐level multidimensionality might lead to inflated item discrimination parameter estimates when the proportion of multidimensional test items to unidimensional test items is as low as 1:5. The Projection IRT model appears to be a useful tool for updating unidimensional item parameter estimates of multidimensional test items for a purified unidimensional interpretation. 相似文献

ABSTRACTA large body of literature in representational studies reflects a deep professional concern over the negative effect of the role of the media in representing significant Others. Western media's coverage of an international event, in this case, a football competition, raises some ethical questions about the choice of specific lexical items and textual contents. Drawing on the work of Stuart Hall's representation theory, this article examines how Turkey, a nation located on the semi-periphery of Europe, is represented in Western media outlets. By looking at the role that sections of the British sports press plays in their construction of the Turkish national identity, I evaluate the Euro 2016 and Euro 2004 reporting of the UEFA European Championship qualifying matches between Turkey and England. I apply a combination of lexical and narrative analysis, and I question the way that Turkey is represented in the British sport texts. The style and language used in the presentation of football games reveals that British media outlets are prone to present England's politically and economically powerful position, and its cultural superiority over Turkey. Findings also suggest that the discourse of the “West and the Rest” is alive in the modern world. 相似文献

Psychometric models based on structural equation modeling framework are commonly used in many multiple-choice test settings to assess measurement invariance of test items across examinee subpopulations. The premise of the current article is that they may also be useful in the context of performance assessment tests to test measurement invariance of raters. The modeling approach and how it can be used for performance tests with less than optimal rater designs are illustrated using a data set from a performance test designed to measure medical students’ patient management skills. The results suggest that group-specific rater statistics can help spot differences in rater performance that might be due to rater bias, identify specific weaknesses and strengths of individual raters, and enhance decisions related to future task development, rater training, and test scoring processes. 相似文献

This study examined the effects of a sexual health curriculum developed for school psychological counsellors in Turkey on the sexual health knowledge of the participating candidates, their beliefs in sexual myths and their tendencies towards ambivalent sexism and sexism in romantic relationships. The study adopted a semi-experimental design. Study participants included an experimental group of 59 students from a programme of guidance and psychological counselling in Ege University’s Faculty of Education and a comparison group of 33 students from the Department of Psychology in the Faculty of Letters. Findings suggested that the sexual health education curriculum increased knowledge of sexuality, decreased beliefs in sexual myths, and decreased ambivalent sexism and sexism in romantic relationships among the candidates. 相似文献

An important component of family life is sexuality education. Being comfortable with one's sexuality is an essential component of individual and family wellness. To this end, parents and teachers who intend to assist in young children's sexuality education must be comfortable and well informed.Nilufer P.

A practical concern for many existing tests is that subscore test lengths are too short to provide reliable and meaningful measurement. A possible method of improving the subscale reliability and validity would be to make use of collateral information provided by items from other subscales of the same test. To this end, the purpose of this article is to compare two different formulations of an alternative Item Response Theory (IRT) model developed to parameterize unidimensional projections of multidimensional test items: Analytical and Empirical formulations. Two real data applications are provided to illustrate how the projection IRT model can be used in practice, as well as to further examine how ability estimates from the projection IRT model compare to external examinee measures. The results suggest that collateral information extracted by a projection IRT model can be used to improve reliability and validity of subscale scores, which in turn can be used to provide diagnostic information about strength and weaknesses of examinees helping stakeholders to link instruction or curriculum to assessment results. 相似文献

Although a few studies report sizable score gains for examinees who repeat performance‐based assessments, research has not yet addressed the reliability and validity of inferences based on ratings of repeat examinees on such tests. This study analyzed scores for 8,457 single‐take examinees and 4,030 repeat examinees who completed a 6‐hour clinical skills assessment required for physician licensure. Each examinee was rated in four skill domains: data gathering, communication‐interpersonal skills, spoken English proficiency, and documentation proficiency. Conditional standard errors of measurement computed for single‐take and multiple‐take examinees indicated that ratings were of comparable precision for the two groups within each of the four skill domains; however, conditional errors were larger for low‐scoring examinees regardless of retest status. In addition, on their first attempt multiple‐take examinees exhibited less score consistency across the skill domains but on their second attempt their scores became more consistent. Further, the median correlation between scores on the four clinical skill domains and three external measures was .15 for multiple‐take examinees on their first attempt but increased to .27 for their second attempt, a value, which was comparable to the median correlation of .26 for single‐take examinees. The findings support the validity of inferences based on scores from the second attempt. 相似文献

This study was conducted in the English Language Teaching Department of a state university in Turkey. The aim of the study was to examine the differences in attitudes of teacher candidates before and after their short-term teaching experience with very young learners (VYL) of English. The study was performed during the first term of the educational year. Within the scope of this study, preservice English teacher candidates were provided the opportunity to practice teaching English to VYL under the supervision of their instructor. This study reports the results of their experiences and their attitudinal changes towards teaching English to VYL. The findings suggest that the attitudes of teacher candidates changed substantially after their practice teaching experiences. Other findings suggest that a colorful atmosphere in the classroom and a variety of activities attract students' interest and help create a more successful learning environment. 相似文献
