An Investigation of Scale Drift for Arithmetic Assessment of ACCUPLACER®. Research Report No. 2010-2
Deng, Hui; Melican, Gerald – College Board, 2010
The current study was designed to extend the current literature to study scale drift in CAT as part of improving quality control and calibration process for ACCUPLACER, a battery of large-scale adaptive placement tests. The study aims to evaluate item parameter drift using empirical data that span four years from the ACCUPLACER Arithmetic…

Riley, Barth B.; Dennis, Michael L.; Conrad, Kendon J. – Applied Psychological Measurement, 2010
This simulation study sought to compare four different computerized adaptive testing (CAT) content-balancing procedures designed for use in a multidimensional assessment with respect to measurement precision, symptom severity classification, validity of clinical diagnostic recommendations, and sensitivity to atypical responding. The four…

Turner, Brandon M.; Betz, Nancy E.; Edwards, Michael C.; Borgen, Fred H. – Measurement and Evaluation in Counseling and Development, 2010
The psychometric properties of measures of self-efficacy for the six themes of Holland's theory were examined using item response theory. Item and scale quality were compared across levels of the trait continuum; all the scales were highly reliable but differentiated better at some levels of the continuum than others. Applications for adaptive…

Barla, Michal; Bielikova, Maria; Ezzeddinne, Anna Bou; Kramar, Tomas; Simko, Marian; Vozar, Oto – Computers & Education, 2010
In this paper we present a method for adaptive selection of test questions according to the individual needs of students within a web-based educational system. It functions as a combination of three particular methods. The first method is based on the course structure and focuses on the selection of the most appropriate topic for learning. The…

Winkelman, Sloane Burke; Kimuna, Sitawa R.; Haithcox-Dennis, Melissa – International Electronic Journal of Health Education, 2012
In the United States, an estimated 1.2 million people are living with HIV/AIDS, and approximately 50,000 new cases of HIV are diagnosed each year. Globally, it is estimated that 33.3 million people are living with HIV/AIDS. The role of mobile populations in the spread of STIs and HIV is well-documented in many countries around the world. Long-haul…

Stone, Elizabeth; Davey, Tim – Educational Testing Service, 2011
There has been an increased interest in developing computer-adaptive testing (CAT) and multistage assessments for K-12 accountability assessments. The move to adaptive testing has been met with some resistance by those in the field of special education who express concern about routing of students with divergent profiles (e.g., some students with…

Finkelman, Matthew; Nering, Michael L.; Roussos, Louis A. – Journal of Educational Measurement, 2009
In computerized adaptive testing (CAT), ensuring the security of test items is a crucial practical consideration. A common approach to reducing item theft is to define maximum item exposure rates, i.e., to limit the proportion of examinees to whom a given item can be administered. Numerous methods for controlling exposure rates have been proposed…

Crisp, Victoria; Johnson, Martin; Novakovic, Nadezda – British Educational Research Journal, 2012
This research investigated whether features of examination questions influence students with dyslexia differently to others, potentially affecting whether they have a fair opportunity to show their knowledge, understanding and skills. A number of science examination questions were chosen. For some questions two slightly different versions were…

Chan, David W. – Gifted Child Quarterly, 2010
Data of item responses to the Impossible Figures Task (IFT) from 492 Chinese primary, secondary, and university students were analyzed using the dichotomous Rasch measurement model. Item difficulty estimates and person ability estimates located on the same logit scale revealed that the pooled sample of Chinese students, who were relatively highly…

Veldkamp, Bernard P.; van der Linden, Wim J. – International Journal of Testing, 2008
In most operational computerized adaptive testing (CAT) programs, the Sympson-Hetter (SH) method is used to control the exposure of the items. Several modifications and improvements of the original method have been proposed. The Stocking and Lewis (1998) version of the method uses a multinomial experiment to select items. For severely constrained…

Chang, Shu-Ren; Plake, Barbara S.; Kramer, Gene A.; Lien, Shu-Mei – Educational and Psychological Measurement, 2011
This study examined the amount of time that different ability-level examinees spend on questions they answer correctly or incorrectly across different pretest item blocks presented on a fixed-length, time-restricted computerized adaptive testing (CAT). Results indicate that different ability-level examinees require different amounts of time to…

Kim, Jiseon – ProQuest LLC, 2010
Classification testing has been widely used to make categorical decisions by determining whether an examinee has a certain degree of ability required by established standards. As computer technologies have developed, classification testing has become more computerized. Several approaches have been proposed and investigated in the context of…

Schmitt, T. A.; Sass, D. A.; Sullivan, J. R.; Walker, C. M. – International Journal of Testing, 2010
Imposed time limits on computer adaptive tests (CATs) can result in examinees having difficulty completing all items, thus compromising the validity and reliability of ability estimates. In this study, the effects of speededness were explored in a simulated CAT environment by varying examinee response patterns to end-of-test items. Expectedly,…

Cho, Hyun-Jeong; Kingston, Neal – Journal of Special Education, 2013
The purpose of this case study was to determine teachers' rationales for assigning students with mild disabilities to alternate assessment based on alternate achievement standards (AA-AAS). In interviews, special educators stated that their primary considerations in making the assignments were low academic performance, student use of extended…

Huang, Jingshan; He, Lei; Davidson-Shivers, Gayle V. – Online Submission, 2011
Effective assessment is vital in educational activities. We propose IWAS (intelligent Web-based assessment system), an intelligent, generalized and real-time system to assess both learning and teaching. IWAS provides a foundation for more efficiency in instructional activities and, ultimately, students' performances. Our contributions are…
