Mead, Ronald J. – 1982
The psychometric properties associated with the "specific objectivity" of the simple logistic model are acknowledged to be far superior to those of competing models. It is therefore the ideal model to be used for test development or for the analysis of any measuring instrument developed within a well-defined psychological construct. In…

Samejima, Fumiko – 1984
Simple sum procedure of the conditional PDF approach (plausiblity of distractor function) combined with the normal approach method was applied for estimating the plausibility functions of the distractors of the Level II vocabulary subtest items of the Iowa Tests of Basic Skills. In so doing, the normal ogive model was adopted for the correct…

Recent developments in dichotomous factor analysis based on multidimensional item response models (Bock and Aitkin, 1981; Muthen, 1978) provide an effective method for exploring the dimensionality of questionnaire items. Implemented in the TESTFACT program, this "full information" item factor analysis accounts not only for the pairwise…

Hirshfeld, Stephen F.; And Others – 1976
A set of procedures for validating the Army's Skill Qualification Tests (SQT) are described. Three phases are discussed: (1) the selection of tasks, (2) the selection of specific content for hands-on performance test items, and of written self-evaluation components, and (3) the establishment of content validity of the hands-on component. The task…

Denson, Teri A. – 1977
Cognitive style research is hindered by a variety of poorly described measures and style classifications and the use of small samples. This study described and compared three group measures of impulsivity/reflectivity, internal/external locus of control; and field dependence/independence to determine the distribution characteristics, psychometric…

Koballa, Thomas, Jr. – 1981
Presented are results of a study attempting to design a reliable and valid instrument measuring the attitudes of teachers toward energy conservation. A 22-item scale is presented as a result of several administrations to preservice elementary teachers. Items were submitted to Likert Item Analysis and further validated by principle components…

Vale, C. David; And Others – 1981
A simulation study to determine appropriate linking methods for adaptive testing items was designed. Three basic data sets for responses were created. These were randomly sampled, systematically sampled, and selected data sets. The evaluative criteria used were fidelity of parameter estimation, asymptotic ability estimates, root-mean-square error…

Maguire, Thomas O.; And Others – 1979
A study was commissioned to develop and validate a test to assess the attitudes of Alberta (Canada) students toward the world of work. An instrument was needed to examine the following five areas of concern: (1) attitudes toward earning a living; (2) perceptions about employer expectations; (3) perceptions about available opportunities; (4)…

Hambleton, Ronald K.; Cook, Linda L. – 1978
The purpose of the present research was to study, systematically, the "goodness-of-fit" of the one-, two-, and three-parameter logistic models. We studied, using computer-simulated test data, the effects of four variables: variation in item discrimination parameters, the average value of the pseudo-chance level parameters, test length,…

Dieterich, Thomas G.; Freeman, Cecilia – 1979
Part One of this guide explores issues in English proficiency testing. Tests are discussed in terms of the aspect of language tested, and of different kinds of test tasks. The following kinds of test task defects are treated: (1) tests that required literacy skills, (2) tasks that reduce to a vocabulary test, and (3) errant notions of linguistic…

Forster, Fred – 1978
Criticisms of norm referenced standardized tests are contrasted with the assumption and claims of proponents of Rasch model testing and item banking. The Rasch test theory model is based on the assumption of equal interval curriculum referenced scales for both students' abilities and test item difficulties. The Portland school district has…

Muiznieks, Viktors; Dennis, J. Richard – 1979
In computer assisted test construction (CATC) systems, the computer is used to perform the mechanical aspects of testing while the teacher retains control over question content. Advantages of CATC systems include question banks, decreased importance of test item security, computer analysis and response to student test answers, item analysis…

Lowry, Stephen R. – 1979
A specially designed answer format was used for three tests in a college level agriculture class of 19 students to record responses to three things about each item: (1) the student's choice of the best answer; (2) the degree of certainty with which the answer was chosen; and (3) all the answer choices which the student was certain were incorrect.…

Kreines, David C.; Mead, Ronald J. – 1979
An explanation is given of what is meant by "sample-free" item calibration and by "item-free" person measurement as these terms are applied to the one-parameter logistic test theory model of Georg Rasch. When the difficulty of an item is calibrated separately for two different samples the results may differ; but, according the…
