Chakrabartty, Satyendra Nath – International Journal of Psychology and Educational Studies, 2021
The paper proposes new measures of difficulty and discriminating values of binary items and test consisting of such items and find their relationships including estimation of test error variance and thereby the test reliability, as per definition using cosine similarities. The measures use entire data. Difficulty value of test and item is defined…

Alqarni, Abdulelah Mohammed – Journal on Educational Psychology, 2019
This study compares the psychometric properties of reliability in Classical Test Theory (CTT), item information in Item Response Theory (IRT), and validation from the perspective of modern validity theory for the purpose of bringing attention to potential issues that might exist when testing organizations use both test theories in the same testing…

Uzun, N. Bilge; Aktas, Mehtap; Asiret, Semih; Yormaz, Seha – Asian Journal of Education and Training, 2018
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…

Relkin, Emily; de Ruiter, Laura; Bers, Marina Umaschi – Journal of Science Education and Technology, 2020
There is a need for developmentally appropriate Computational Thinking (CT) assessments that can be implemented in early childhood classrooms. We developed a new instrument called "TechCheck" for assessing CT skills in young children that does not require prior knowledge of computer programming. "TechCheck" is based on…

Lee, Minji K.; Sweeney, Kevin; Melican, Gerald J. – Educational Assessment, 2017
This study investigates the relationships among factor correlations, inter-item correlations, and the reliability estimates of subscores, providing a guideline with respect to psychometric properties of useful subscores. In addition, it compares subscore estimation methods with respect to reliability and distinctness. The subscore estimation…

Sauro, Jeff – ProQuest LLC, 2016
Consumers spend an increasing amount of time and money online finding information, completing tasks, or making purchases. The quality of the website experience has become a key differentiator for organizations--affecting whether they purchase and their likelihood to return and recommend a website to friends. Two instruments were created to more…

Retnawati, Heri – Turkish Online Journal of Educational Technology - TOJET, 2015
This study aimed to compare the accuracy of the test scores as results of Test of English Proficiency (TOEP) based on paper and pencil test (PPT) versus computer-based test (CBT). Using the participants' responses to the PPT documented from 2008-2010 and data of CBT TOEP documented in 2013-2014 on the sets of 1A, 2A, and 3A for the Listening and…

Meneses, Alejandra; Uccelli, Paola; Santelices, María Verónica; Ruiz, Marcela; Acevedo, Daniela; Figueroa, Javiera – Reading Research Quarterly, 2018
Although literacy achievement has improved in Chile, adolescents' underperformance in reading comprehension is still a serious concern. In English, core academic-language skills (CALS) have been found to significantly predict reading comprehension, even controlling for academic vocabulary knowledge. CALS are high-utility language skills that…

Lane, Kathleen Lynne; Oakes, Wendy Peia; Cantwell, Emily D.; Menzies, Holly Mariah; Schatschneider, Christopher; Lambert, Warren; Common, Eric Alan – Journal of Emotional and Behavioral Disorders, 2017
We report results of an exploratory validation study of the "Student Risk Screening Scale-Internalizing and Externalizing" (SRSS-IE) applied with the first sample of middle and high school students from nine middle and three high schools from three states. The "Student Risk Screening Scale" (SRSS) was modified to broaden the…

Zimmerman, Donald W. – Journal of Educational and Behavioral Statistics, 2011
Many well-known equations in classical test theory are mathematical identities in populations of individuals but not in random samples from those populations. First, test scores are subject to the same sampling error that is familiar in statistical estimation and hypothesis testing. Second, the assumptions made in derivation of formulas in test…

Baird, Jo-Anne; Black, Paul – Research Papers in Education, 2013
Much has already been written on the controversies surrounding the use of different test theories in educational assessment. Other authors have noted the prevalence of classical test theory over item response theory in practice. This Special Issue draws together articles based upon work conducted on the Reliability Programme for England's…

He, Qingping; Hayes, Malcolm; Wiliam, Dylan – Research Papers in Education, 2013
The accuracy of the results of the national tests in English, mathematics and science taken by 11-year olds in England has been a matter of much debate since their introduction in 1994, with estimates of the proportion of students incorrectly classified varying from 10 to 30%. Using live data from the 2009 and 2010 administration of the national…

Sussman, Joshua; Beaujean, A. Alexander; Worrell, Frank C.; Watson, Stevie – Measurement and Evaluation in Counseling and Development, 2013
Item response models (IRMs) were used to analyze Cross Racial Identity Scale (CRIS) scores. Rasch analysis scores were compared with classical test theory (CTT) scores. The partial credit model demonstrated a high goodness of fit and correlations between Rasch and CTT scores ranged from 0.91 to 0.99. CRIS scores are supported by both methods.…

Bristow, M.; Erkorkmaz, K.; Huissoon, J. P.; Jeon, Soo; Owen, W. S.; Waslander, S. L.; Stubley, G. D. – IEEE Transactions on Education, 2012
Any meaningful initiative to improve the teaching and learning in introductory control systems courses needs a clear test of student conceptual understanding to determine the effectiveness of proposed methods and activities. The authors propose a control systems concept inventory. Development of the inventory was collaborative and iterative. The…
