Raykov, Tenko; Pusic, Martin – Educational and Psychological Measurement, 2023
This note is concerned with evaluation of location parameters for polytomous items in multiple-component measuring instruments. A point and interval estimation procedure for these parameters is outlined that is developed within the framework of latent variable modeling. The method permits educational, behavioral, biomedical, and marketing…

Peabody, Michael R. – Measurement: Interdisciplinary Research and Perspectives, 2023
Many organizations utilize some form of automation in the test assembly process; either fully algorithmic or heuristically constructed. However, one issue with heuristic models is that when the test assembly problem changes the entire model may need to be re-conceptualized and recoded. In contrast, mixed-integer programming (MIP) is a mathematical…

Gorbett, Luke J.; Chapamn, Kayla E.; Liberatore, Matthew W. – Advances in Engineering Education, 2022
Spreadsheets are a core computational tool for practicing engineers and engineering students. While Microsoft Excel, Google Sheets, and other spreadsheet tools have some differences, numerous formulas, functions, and other tasks are common across versions and platforms. Building upon learning science frameworks showing that interactive activities…

Climie, Emma A.; Rostad, Kristin – Journal of Psychoeducational Assessment, 2011
This article presents a review of the "Wechsler Adult Intelligence Scale-Fourth Edition" (WAIS-IV), an individually administered measure of cognitive ability for individuals aged 16 years, 0 months to 90 years, 11 months. The WAIS-IV was designed with a number of specific goals including updated norms, increased user friendliness,…

Shuqun, Yang; Shuliang, Ding; Zhiqiang, Yao – International Journal of Distance Education Technologies, 2009
Cognitive diagnosis (CD) plays an important role in intelligent tutoring system. Computerized adaptive testing (CAT) is adaptive, fair, and efficient, which is suitable to large-scale examination. Traditional cognitive diagnostic test needs quite large number of items, the efficient and tailored CAT could be a remedy for it, so the CAT with…

Finger, Michael S. – International Journal of Testing, 2004
MicroFACT 2.0, an item factor analysis computer program, was reviewed. Program features were described in detail, as well as the program output. The performance of MicroFACT was evaluated on a Windows 2000, Pentium III platform. MicroFACT was found to be fairly easy to use, and one problem encountered was reported. Program requirements and…

Guttman, Louis – Psychometrika, 1988
Two discrimination coefficients, known as "disco" and "odisco," are proposed for measuring the extent of overlap in distributions as a direct function of the variance between the arithmetic means. These coefficients are related to K. Pearson's "eta" (1905) and R. A. Fisher's "F" (1950). (SLD)

Rupp, Andre A. – International Journal of Testing, 2003
Item response theory (IRT) has become one of the most popular scoring frameworks for measurement data. IRT models are used frequently in computerized adaptive testing, cognitively diagnostic assessment, and test equating. This article reviews two of the most popular software packages for IRT model estimation, BILOG-MG (Zimowski, Muraki, Mislevy, &…

Vale, C. David; Gialluca, Kathleen A. – Applied Psychological Measurement, 1988
To determine which produced the most accurate item parameter estimates, four methods of item response theory were evaluated: (1) heuristic estimates; (2) the ANCILLES program; (3) the LOGIST program; and (4) the ASCAL program. LOGIST and ASCAL produced estimates of superior and essentially equivalent accuracy. (SLD)

Madsen, Harold S. – 1986
The most appropriate statistical model for the small-scale (n<100) studies common in language testing research is the Rasch one-parameter logistic model. The Rasch model provides a wide range of options for conducting research, refining existing examinations, and developing tailored (computerized adaptive) language tests. Three investigations…

Aiken, Lewis R. – Educational and Psychological Measurement, 1989
Two alternatives to traditional item analysis and reliability estimation procedures are considered for determining the difficulty, discrimination, and reliability of optional items on essay and other tests. A computer program to compute these measures is described, and illustrations are given. (SLD)

Hsu, Tse-chi; Yu, Lifa – Educational Measurement: Issues and Practice, 1989
How computers are used to analyze item data is reviewed, and the information that existing item-analysis programs provide is described. Summaries of studies comparing the performance of some of these packages reveal some of their current limitations. Emphasis is on the usefulness to educational practice of these packages. (SLD)

Giordano, Carolyn; Subhiyah, Raja; Hess, Brian – Online Submission, 2005
There are few certifying or recertifying examinations in the medical field that are given in a take-home format. This stems from a concern that examinees may discuss items with peers, or save copies of items on the exam and then pass them on to others. This study examined if item exposure on take-home examinations influences the difficulty of the…

Liu, Chao-Lin – Educational Technology & Society, 2005
The author analyzes properties of mutual information between dichotomous concepts and test items. The properties generalize some common intuitions about item comparison, and provide principled foundations for designing item-selection heuristics for student assessment in computer-assisted educational systems. The proposed item-selection strategies…
