The effect of the construction of mixed anchor items on the test equating in mixed-format tests
Korean Society for Educational Evaluation, 2023With the introduction of innovative items in the computer-based NAEA, the item format became diversified, and the current method of selecting anchor items from multiple-choice (MC) items became burdensome for test developers. The purpose of this study is to examine whether a mixed-format anchor items including both MC and constructed-response (CR ...

LINKING MIXED‐FORMAT TESTS USING MULTIPLE‐CHOICE ANCHORS
ETS Research Report Series, 2010ABSTRACTThis study examined the use of an all multiple‐choice (MC) anchor for linking mixed format tests containing both MC and constructed‐response (CR) items, in a nonequivalent groups design. An MC‐only anchor could effectively link two such test forms if either (a) the MC and CR portions of the test measured the same construct, so that the MC ...

Evaluating Statistical Targets for Assembling Parallel Mixed‐Format Test Forms
Journal of Educational Measurement, 2017Test assembly is the process of selecting items from an item pool to form one or more new test forms. Often new test forms are constructed to be parallel with an existing (or an ideal) test. Within the context of item response theory, the test information function (TIF) or the test characteristic curve (TCC) are commonly used as statistical targets to ...

Enhancing Pool Utilization in Constructing the Multistage Test Using Mixed-Format Tests
Applied Psychological Measurement, 2014This study investigated a new pool utilization method of constructing multistage tests (MST) using the mixed-format test based on the generalized partial credit model (GPCM). MST simulations of a classification test were performed to evaluate the MST design.

Panel Design Variations in the Multistage Test Using the Mixed-Format Tests
Educational and Psychological Measurement, 2012This study compared various panel designs of the multistage test (MST) using mixed-format tests in the context of classification testing. Simulations varied the design of the first-stage module. The first stage was constructed according to three levels of test information functions (TIFs) with three different TIF centers.

Extension of caution indices to mixed‐format tests
British Journal of Mathematical and Statistical Psychology, 2018Tatsuoka suggested several extended caution indices and their standardized versions, and these have been used as person‐fit statistics by various researchers. However, these indices are only defined for tests with dichotomous items. This paper extends two of the popular standardized extended caution indices for use with polytomous items and mixed ...

IRT Approaches to Modeling Scores on Mixed‐Format Tests
Journal of Educational Measurement, 2019AbstractThis article considers psychometric properties of composite raw scores and transformed scale scores on mixed‐format tests that consist of a mixture of multiple‐choice and free‐response items. Test scores on several mixed‐format tests are evaluated with respect to conditional and overall standard errors of measurement, score reliability, and ...

Customizing Bayesian multivariate generalizability theory to mixed-format tests
Behavior Research MethodsMixed-format tests, which typically include dichotomous items and polytomously scored tasks, are employed to assess a wider range of knowledge and skills. Recent behavioral and educational studies have highlighted their practical importance and methodological developments, particularly within the context of multivariate generalizability theory. However,

IRT‐Estimated Reliability for Tests Containing Mixed Item Formats
Journal of Educational Measurement, 2014As a global measure of precision, item response theory (IRT) estimated reliability is derived for four coefficients (Cronbach's α, Feldt‐Raju, stratified α, and marginal reliability). Models with different underlying assumptions concerning test‐part similarity are discussed. A detailed computational example is presented for the targeted coefficients. A

Ethnic DIF in Reading Tests With Mixed Item Formats
Educational Assessment, 2011This article presents a study of ethnic Differential Item Functioning (DIF) for 4th-, 7th-, and 10th-grade reading items on a state criterion-referenced achievement test. The tests, administered 1997 to 2001, were composed of multiple-choice and constructed-response items.
