Three rating scales--with all positive or all negative wording, or a mixture of both--were administered to 522 children in grades four through six. The results indicated that it was difficult for students to indicate agreement by disagreeing with a negative statement. This affected test validity. Author/GDC)

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 paper discusses the use of latent class structure as a modelling framework for tests in which much of the data conforms to a relatively small number of systematic patterns. Application of this framework to the analysis of tests has been limited because available parameter estimation algorithms can only handle a relatively small number of…

This paper addresses the information revealed in incorrect option selection on multiple choice items. Multilinear Formula Scoring (MFS), a theory providing methods for solving psychological measurement problems of long standing, is first used to estimate option characteristic curves for the Armed Services Vocational Aptitude Battery Arithmetic…

Covariance structure modelling is applied to the problem of estimating reliability and measurement error in survey data. To provide a basis for grouping certain question or variable types (data from questions), a simple typology based on the formal characteristics of the questions is outlined. From this classification, models for the different…

Procedures devised for computing factor matching statistics in questionnaire construction are described. In a study of the impact of vocational education on social, affective and nontechnical development of students, an attitude questionnaire to measure outcomes was developed. Each item in the final section had a six-point Likert type response…

The Rasch item analysis model is supposed to yield norm-free estimates of ability and easiness values, but there are several possible interpretations of the nature and extent of such norm-freeness. One such interpretation was that to involve the scores of one single experimental group of testees which were embedded in four differently skewed…

This report summarizes the results of research designed to study the psychometric and technological feasibility of adaptive testing to assess spatial ability. Data was collected from high school students on two types of spatial items: three-dimensional cubes and hidden figure items. The analysis of the three-dimensional cubes focused on the fit of…

Field tests of test items are useful in developing cutting scores for important tests, such as teacher certification examinations and high school graduation tests, because they indicate test item quality and estimate future examinee performance. However, field test data may provide a faulty indication of examinee performance on the real test.…

The comparative effects of various sequences of test items were examined for over 900 graduate students enrolled in an educational research course at The University of Alabama, Tuscaloosa. experiment, which was conducted a total of four times using four separate tests, presented three different arrangements of 50 multiple-choice items: (1)…

Five questionnaire forms containing 61 items specifying potential inservice topics for public school teachers were sent to a stratified random sample of Indiana public school administrators and curriculum supervisors. The five forms differed in that, for two forms, the items were ungrouped and appeared in different orders; and, for three forms,…

Two types of sensitivity indices were developed in this paper, one internal to the total test and the second external. To evaluate the success of these statistics the three criteria suggested for a satisfactory index of item quality were considered. The Internal Sensitivity Index appears to meet these demands. Certainly it is easily computed. In…

A conventional vocabulary test and two forms of a stradaptive vocabulary test were administered by a time-shared computer system to undergraduate college students. The two stradaptive tests differed in that one counted question mark responses (i.e., omitted items) as incorrect and the other ignored items responded to with question marks.…

This study empirically investigated the validity and utility of the stratified adaptive computerized testing model (stradaptive]developed by Weiss (1973). The model presents a tailored testing strategy based on Binet IQ measurement theory and Lord's (1972) modern test theory. Nationally normed School and College Ability Test Verbal analogy items…

The development of a series of parallel single-topic tests for testing attainment of 14 objectives concerned with inquiry skill in biology is discussed. The series of eight two-part tests are called "Explorations in Biology" (EIB). (CK)
