To test the applicability of item response theory (IRT) to the Korean Nurses' Licensing Examination (KNLE), item analysis was performed after testing the unidimensionality and goodness-of-fit. The results were compared with those based on classical test theory. The results of the 330-item KNLE administered to 12,024 examinees in January 2004 were analyzed. Unidimensionality was tested using DETECT and the goodness-of-fit was tested using WINSTEPS for the Rasch model and Bilog-MG for the two-parameter logistic model. Item analysis and ability estimation were done using WINSTEPS. Using DETECT, Dmax ranged from 0.1 to 0.23 for each subject. The mean square value of the infit and outfit values of all items using WINSTEPS ranged from 0.1 to 1.5, except for one item in pediatric nursing, which scored 1.53. Of the 330 items, 218 (42.7%) were misfit using the two-parameter logistic model of Bilog-MG. The correlation coefficients between the difficulty parameter using the Rasch model and the difficulty index from classical test theory ranged from 0.9039 to 0.9699. The correlation between the ability parameter using the Rasch model and the total score from classical test theory ranged from 0.9776 to 0.9984. Therefore, the results of the KNLE fit unidimensionality and goodness-of-fit for the Rasch model. The KNLE should be a good sample for analysis according to the IRT Rasch model, so further research using IRT is possible.

AbstrakPengetahuan matematika, didaktika, dan teknologi yang harus dimilik oleh calon guru dan guru, sebelumnya diukur dengan metode classical test theory (CTT), namun memiliki keterbatasan. Penelitian bertujuan mengetahui pengetahuan tersebut dengan metode yang diprekdiksi lebih akurat yaitu item response theory (IRT) dari rasch model. Metode penelitian meliputi survey pengetahuan matematika dan didaktika serta survey pengetahuan teknologi menggunakan angket. Subjek penelitian yaitu 38 mahasiswa tahun kedua calon guru sekolah dasar dari sebuah institusi pendidikan guru sekolah dasar di Pekanbaru. Hasil studi menunjukkan calon guru sekolah dasar memiliki pengetahuan matematika dan teknologi cukup baik, namun pengetahuan didaktika sangat rendah. Analisis pengetahuan calon guru menggunkan rasch model mampu memberikan gambaran tingkat kesulitan soal/item yang diberikan, tingkat pengetahuan responden, dan interaksi antar responden dan antar soal. Institusi pendidikan perlu mengembangkan pembelajaran bagi calon guru sekolah dasar yang mampu mendukung penguatan dan pengembangan pengetahuan matematika, didaktika, dan teknologi. Prospective Elementary Teachers’ Mathematical, Didactic, and Technological Knowledge Using Rasch Model Analysis AbstractKnowledge of mathematics, didactics, and technology that must be owned by pre-service and in-service teachers, previously measured by the classical test theory (CTT), but has limitations. Study aims to determine that knowledge with a more accurate prediction method using the item response theory (IRT) from the Rasch model. Study used a survey of mathematical and didactic knowledge, and a survey of technological knowledge with a scale. The subjects were 38 second-year students from an elementary school teacher education institution in Pekanbaru. This study indicates that pre-service teachers have relatively sufficient mathematics and technological knowledge, but they were lack of didactic knowledge. Analysis of pre-service teachers’ knowledge using the Rasch model can provide an overview of the difficulty level of the items given, the level of pre-service teachers’ knowledge, and the interaction between respondents and between questions. Institutions need to develop learning instruction for pre-service teachers that can support the strengthening and development of their mathematical, didactic, and technological knowledge.

PLAYself is a tool designed for self-description of physical literacy in children and youth. We examined the tool using both the Rasch model and Classical Test Theory to explore its psychometric properties. A random selection of 300 children aged 8-14 (47.3% female) from a dataset of 8,513 Canadian children were involved in the Rasch analysis. The three subscales of the measure demonstrated good fit to the Rasch model, satisfying requirements of unidimensionality, having good fit statistics (item and person fit residuals =-.17-1.47) and internal reliability (PSI=.70-.82), and a lack of item bias and problematic local dependency. In a separate comparable sample, 297 children also aged 8-14 (53.9% female) completed the PLAYfun, Physical Self-Description Questionnaire (PSDQ), Physical Activities Measure-Revised (MPAM-R), a physical activity inventory (PLAYinventory), and repeated the PLAYself seven days later. The tests with this sample confirmed test-retest reliability (ICC=.81-.84), and convergent and construct validity consistent with contemporary physical literacy definitions. Overall, the PLAYself demonstrated robust psychometric properties, and is recommended for researchers and practitioners who are interested in assessing self-reported physical literacy. Novelty bullets: • The PLAYself is a self-reported measure of physical literacy • This study validates the measure using the Rasch model and classical test theory • The PLAYself was found to have strong psychometric properties

Abstract Purpose The World Health Organization Disability Assessent Schedule 2.0 (WHODAS 2.0) assesses disability in individuals irrespective of their health condition. Previous studies validated the usefulness of the WHODAS 2.0 using classical test theory. This study is the first investigating the psychometric properties of the 12-items WHODAS 2.0 in patients with cancer using item analysis according to the Rasch model. Methods In total, 350 cancer patients participated in the study. Rasch analysis of the 12-items version of the WHODAS 2.0 was conducted and included testing unidimensionality, local independence, and testing for differential item functioning (DIF) with regard to age, gender, type of cancer, presence of metastases, psycho-oncological support, and duration of disease. Results After accounting for local dependence, which was mainly found across items of the same WHODAS domain, satisfactory overall fit to the Rasch model was established (χ2 = 36.14, p = 0.07) with good reliability (PSI = 0.82) and unidimensionality of the scale. DIF was found for gender (testlet ‘Life activities’) and age (testlet ‘Getting around/Self-care’), but the size of DIF was not substantial. Conclusion Overall, the analysis results according to the Rasch model support the use of the WHODAS 2.0 12-item version as a measure of disability in cancer patients.
