Journal of Educational Measurement Vol. 51, No. 2 (2014) pp. 178–200
Sometimes, test-takers may not be able to attempt all items to the best of their ability (with full effort) due to personal factors (e.g., low motivation) or testing conditions (e.g., time limit), resulting in poor performances on certain items,...
Educational and Psychological Measurement Vol. 71, No. 1 (February 2011) pp. 114–128
The generalized graded unfolding model (GGUM) has been recently developed to describe item responses to Likert items (agree-disagree) in attitude measurement. In this study, the authors (a) developed two item selection methods in computerized...
Computerized Classification Testing under the One-Parameter Logistic Response Model with Ability-Based Guessing
Educational and Psychological Measurement Vol. 71, No. 6 (December 2011) pp. 925–941
The one-parameter logistic model with ability-based guessing (1PL-AG) has been recently developed to account for effect of ability on guessing behavior in multiple-choice items. In this study, the authors developed algorithms for computerized...
Educational and Psychological Measurement Vol. 74, No. 1 (February 2014) pp. 116–138
Extreme response style (ERS) is a systematic tendency for a person to endorse extreme options (e.g., strongly disagree, strongly agree) on Likert-type or rating-scale items. In this study, we develop a new class of item response theory (IRT) models...
Journal of Educational Measurement Vol. 52, No. 2 (2015) pp. 125–143
Cognitive diagnosis models provide profile information about a set of latent binary attributes, whereas item response models yield a summary report on a latent continuous trait. To utilize the advantages of both models, higher order cognitive...
Journal of Educational Measurement Vol. 48, No. 4 (2011) pp. 441–456
Rating scale items have been widely used in educational and psychological tests. These items require people to make subjective judgments, and these subjective judgments usually involve randomness. To account for this randomness, Wang, Wilson, and...
Applied Psychological Measurement Vol. 28, No. 5 (2004) pp. 295–316
Multidimensional adaptive testing (MAT) procedures are proposed for the measurement of several latent traits by a single examination. Bayesian latent trait estimation and adaptive item selection are derived. Simulations were conducted to compare the ...
Educational and Psychological Measurement Vol. 74, No. 3 (June 2014) pp. 495–515
In the social sciences, latent traits often have a hierarchical structure, and data can be sampled from multiple levels. Both hierarchical latent traits and multilevel data can occur simultaneously. In this study, we developed a general class of...
Multilevel, Two-Parameter, and Random-Weights Generalizations of a Model with Internal Restrictions on Item Difficulty
Applied Psychological Measurement Vol. 34, No. 1 (2010) pp. 46–65
In this study, all the advantages of slope parameters, random weights, and latent regression are acknowledged when dealing with component and composite items by adding slope parameters and random weights into the standard item response model with...
Educational and Psychological Measurement Vol. 75, No. 1 (February 2015) pp. 157–178
Many scales contain both positively and negatively worded items. Reverse recoding of negatively worded items might not be enough for them to function as positively worded items do. In this study, we commented on the drawbacks of existing approaches...
International Journal of Educational Research Vol. 75, No. 1 (2016) pp. 115–133
Educational and Psychological Measurement Vol. 72, No. 4 (August 2012) pp. 687–708
The DIF-free-then-DIF (DFTD) strategy consists of two steps: (a) select a set of items that are the most likely to be DIF-free and (b) assess the other items for DIF (differential item functioning) using the designated items as anchors. The rank...
Applied Psychological Measurement Vol. 36, No. 8 (November 2012) pp. 689–706
In the human sciences, a common assumption is that latent traits have a hierarchical structure. Higher order item response theory models have been developed to account for this hierarchy. In this study, computerized adaptive testing (CAT) algorithms ...
The Random-Threshold Generalized Unfolding Model and Its Application of Computerized Adaptive Testing
Applied Psychological Measurement Vol. 37, No. 3 (May 2013) pp. 179–200
The random-threshold generalized unfolding model (RTGUM) was developed by treating the thresholds in the generalized unfolding model as random effects rather than fixed effects to account for the subjective nature of the selection of categories in...
Applied Psychological Measurement Vol. 37, No. 7 (October 2013) pp. 563–582
Interest in developing computerized adaptive testing (CAT) under cognitive diagnosis models (CDMs) has increased recently. CAT algorithms that use a fixed-length termination rule frequently lead to different degrees of measurement precision for...
Journal of Educational Measurement Vol. 49, No. 4 (2012) pp. 419–445
In some tests, examinees are required to choose a fixed number of items from a set of given items to answer. This practice creates a challenge to standard item response models, because more capable examinees may have an advantage by making wiser...
Applied Psychological Measurement Vol. 37, No. 8 (November 2013) pp. 619–637
Many latent traits in the human sciences have a hierarchical structure. This study aimed to develop a new class of higher order item response theory models for hierarchical latent traits that are flexible in accommodating both dichotomous and...
International Journal on E-Learning Vol. 7, No. 1 (January 2008) pp. 23–39
TransAsia Airway is one of the four domestic airlines in Taiwan. Taiwan has 13 domestic airports with the longest distance between two airports being about 400 kilometers. The domestic airline market is highly competitive. TransAsia decided to apply ...
