Simulation Study of Item Validity Testing and Item Discrimination Index [PDF]

Proceeding of the Electrical Engineering Computer Science and Informatics, 2014
In psychology or educational research, we often want to test the validity of our instrument. Usually we use the Pearson coefficient of correlation in validity testing. However, the distribution of the data are not always normal distribution so it is also possible to use the Spearman and Kendall coefficient of correlation to test the validity of items ...

Conditional Dependencies Between Response Time and Item Discrimination: An Item-Level Meta-Analysis.

Educational and Psychological Measurement
The use of process data such as response time (RT) in psychometrics has generally focused on the relationship between speed and accuracy. The potential relationships between RT and item discrimination remain less explored. In this study, we propose a model for simultaneously estimating the relationships between RT and item discrimination at the person,

Item Discrimination and Type I Error in the Detection of Differential Item Functioning

Educational and Psychological Measurement, 2012
In 2009, DeMars stated that when impact exists there will be Type I error inflation, especially with larger sample sizes and larger discrimination parameters for items. One purpose of this study is to present the patterns of Type I error rates using Mantel–Haenszel (MH) and logistic regression (LR) procedures when the mean ability between the focal and

An Item-Difficulty Based Speech Discrimination Test

Journal of Speech and Hearing Research, 1971
In an attempt to improve the differentiating ability of monosyllabic speech discrimination tests, two equivalent, 25-word test recordings with rectilinear distributions of item difficulty were constructed from W-22 Hirsh recordings. These lists and selected half lists of the standard W-22 recordings were then presented to 40 ears of listeners with ...

Learning as a Function of Haptic Discriminability among Items

The American Journal of Psychology, 1984
In Experiment 1, braille symbols for the letters A-J were found to be more haptically discriminable from one another than braille symbols for the letters K-T. In Experiment 2, subjects learned the names for the A-J symbols faster than for the K-T symbols.

The Development of Constant Items for Speech Discrimination Testing

Journal of Speech and Hearing Research, 1968
Subjects were English-speaking adults with hearing impairment. Etiology of hearing loss did not enter into selection. Consonant errors were observed on speech discrimination test lists employing a closed-set response system. Fifteen subjects were employed for the first list and 20 each for the remaining four lists, with an occasional subject serving in

Discovering discriminative test items for achievement tests

Expert Systems with Applications, 2012
One of the essential goals of test designing is to select items with the most discriminative power. In the past, most research has assumed there is no dependent relationship among test items, so that test papers are often produced by selecting items with individual discriminations.

ITEM DIFFICULTY AND DISCRIMINATION AS A FUNCTION OF STEM COMPLETENESS

Psychological Reports, 1991
The effects on item difficulty and discrimination of stem completeness (complete stem or incomplete stem) for multiple-choice items were studied experimentally. Subjects (166 junior education students) were classified into three achievement groups (low, medium, high) and one of two forms of a multiple-choice test was randomly assigned to each subject ...

Two Generalizations of the Item Discrimination Index to Multi-Score Items

The Journal of Experimental Education, 1971
Two general item analysis indices which apply to multi-score items are developed as generalizations of a popular index applicable to dichotomous items. The indices of discrimination are of two types: one based on differential difficulty and the other on net number of positive discriminations. The usefulness and limitations of each are discussed.

Polytomous Explanatory Item Response Models for Item Discrimination: Assessing Negative-Framing Effects in Social-Emotional Learning Surveys [PDF]

Behavior Research Methods
Modeling item parameters as a function of item characteristics has a long history but has generally focused on models for item location. Explanatory item response models for item discrimination are available but rarely used.
