A computerized flexilevel test was implemented and its ability estimates were compared with those of a Bayesian estimation based computerized adaptive test (CAT) as well as with known true ability estimates. Results showed that when the flexilevel test was terminated according to Lord's criterion, its ability estimates were highly and…

The combined field tests for the third follow-up survey of High School and Beyond (HSB) and the fifth follow-up survey of the National Longitudinal Study of the High School Class of 1972 (NLS-72) were conducted during the spring of 1985. The overall purposes of the field tests were to evaluate questionnaires and procedures to be used for the…

The focus of this study is on the estimation procedures implemented in BILOG, a computer program. One purpose is to compare the item parameter estimates produced by various procedures available in BILOG. Four different models are used: the one, two, and three parameter model and a three parameter model with common guessing parameters. The results…

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…

This study investigated the feasibility of the use of the three-parameter item response theory (IRT) model in Florida's minimum competency testing program. The paper includes the following sections: (1) a description of the procedures currently being used by the assessment program, with an emphasis on procedures currently involving the Rasch…

Methodological and conceptual issues arising from a study of student perceptions of secondary school class climate are discussed. Through a pilot study, 113 Likert-type items were collected, consisting of teacher-focused dimensions, classroom-focused dimensions, and instructional practices. Factor and cluster analyses were used at the item level.…

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…

An approach was developed based on item-response models defined at the level of salient subject groups rather than at the level of individuals, designed for use with multiple-matrix sampling designs. In each of three National Assessment of Educational Progress (NAEP) mathematics subtopics, Reiser's group-effects latent trait model was fitted to…

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…

Data gathered from large-scale assessments in the Ontario Assessment Instrument Pool (OAIP) are examined. Implications for science instruction are to be found at the item level; the items should not involve more than two or three steps if the responses are to be informative. Items are collected and linked to provincial curriculum guidelines. These…

It was hypothesized in this document that lowered self-concept would be associated with children exhibiting problems such as delinquency or childhood depression. The differences in self-concept between 97 clinic and 485 nonclinic children were investigated by administration of the Piers-Harris Children's Self Concept Scale. The reported…

This research program was designed to investigate the applications of item response theory and computerized adaptive testing to the unique problems of the measurement of ability and the measurement of achievement. The research utilized a combination of monte carlo simulation studies and live-testing studies. The research approach for adaptive…

This 32-item bibliography was compiled to provide access to research and discussions of domain referenced testing. It is not limited to any educational level, nor is it confined to any specific curriculum area. Five data bases were searched by computer. A computer search of the Educational Resources Information Center (ERIC) data base yielded…

The utility of the Rasch logistic measurement model in longitudinal analyses of children's self-concept was investigated. Calibration of an 80-item self-concept measure from the responses of 1,000 elementary school children resulted in the identification of 25 items that fit the model. Repeated measures analyses of variance used to assess the…

Confirmatory factor analysis is presented as providing appropriate techniques for the analysis and evaluation of questionnaires and tests if the content of the measure can be identified as consisting of groups of items, with each group measuring only a single trait. This approach is contrasted with latent trait theory which assumes (and does not…
