Computerized adaptive testing for language teaching and learning takes advantage of two properties of the computer: its number-crunching and multiple-branching capabilities. Adaptive testing has also been called tailored testing because it aims at presenting items that suit the student's competence and that are informative, using an item bank and…

In multiple-choice items the response probability on an item may be viewed as the result of two distinct latent processes--a cognitive process to solve the problem, and another random process that leads to the choice of a certain alternative (the process of giving the actual response). An incomplete latent class model is formulated that describes…

Computer learners often develop explanations of events they observe during training. Recent work on generalization suggests that explanations may be valuable in permitting learners to develop generalizations from one or a few examples. This study explores the idea by describing four generalization paradigms in which explanations play a part:…

The writing objectives and the measurement specifications presented in this document are congruent with the Texas State Board of Education Rules for Curriculum. The objectives are provided for teachers and for test developers involved with the preparation of the Texas Educational Assessment of Minimum Skills (TEAMS) tests. As of 1985-86 academic…

Although perfectly scalable items rarely occur in practice, Guttman's concept of a scale has proved to be valuable to the development of measurement theory. If the score distribution is uniform and there is an equal number of items at each difficulty level, both the elements and the eigenvalues of the Pearson correlation matrix of dichotomous…

This competency test package was developed, based on the results of a needs assessment of postsecondary office occupations instructors in Texas, to test transcription competencies taught in audiovisual instructional modules. However, the tests, accompanied by performance objectives, are of a general nature and could be used to evaluate competency…

This competency test package was developed, based on the results of a needs assessment of postsecondary office occupations instructors in Texas, to test decision-making competencies taught in audiovisual instructional modules. However, the tests, accompanied by performance objectives, are of a general nature and could be used to evaluate…

This project was conducted to create visual media technology competencies for articulation in order to (1) provide a basis from which to assess similar instructional efforts at other vocational and prevocational institutions; (2) provide a detailed listing of competencies required by Spokane Falls Community College (Washington) for instructors…

Comments are made on the review papers presented by six Dutch psychometricians: Ivo Molenaar, Wim van der Linden, Ed Roskam, Arnold Van den Wollenberg, Gideon Mellenbergh, and Dato de Gruijter. Molenaar has embraced a pragmatic viewpoint on Bayesian methods, using both empirical and pure approaches to solve educational research problems. Molenaar…

This report provides an overview of the current applications of computer technology to construct test items and/or to formulate tests according to sound measurement principles. The test items may be computer-generated from strategies programmed by test constructors, or pre-constructed by item writers and stored in computer memory. The tests…

A primary goal of this study was to determine the extent to which item difficulty was related to item position and, if a significant relationship was found, to suggest adjustments to predicted item difficulty that reflect differences in item position. Item response data from the Medical College Admission Test (MCAT) were analyzed. A data set was…

This paper reviews the basic elements of the EM approach to estimating item parameters and illustrates its use with one simulated and one real data set. In order to illustrate the use of the BILOG computer program, runs for 1-, 2-, and 3-parameter models are presented for the two sets of data. First is a set of responses from 1,000 persons to five…

Appropriate evaluation can greatly enhance the teaching process, and this resource packet is designed to help make testing more efficient. Tests and test items are featured in these listings, and information on test construction is provided. The various sources which are highlighted include: (1) professional organizations; (2) journals and…

The reliability of item bias estimates was studied for four methods: (1) the transformed delta method; (2) Shepard's modified delta method; (3) Rasch's one-parameter residual analysis; and (4) the Mantel-Haenszel procedure. Bias statistics were computed for each sample using all methods. Data were from administration of multiple-choice items from…

An overview of the research needed on the new Test of Written English (TWE), a section of the Test of English as a Foreign Language (TOEFL), looks at research needs in the areas of test validity, test reliability, topic development, and equating. Suggested topics for study include: the uniqueness of the construct measured by the test, in…
