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…

In order to construct a plan drawing test for emotionally disturbed children, 1,250 children from 6 to 15 years old were asked to draw plans of their houses. Forty items in this cross-sectional sample illustrate a regular and rapid increase with age from the purely vertical pictures of houses at 6 years to the mainly horizontal representations at…

The purpose of this report is to distill curricular and testing implications of brain research. The report will focus on three topics. One topic is the possibility that brain lateralization--that is, the degree to which the two brain hemispheres specialize in different types of information processing--is an individual differences variable that…

A conventional verbal ability test and a Bayesian adaptive verbal ability test were compared using a variety of psychometric criteria. Tests were administered to 550 Marine recruits, half of whom received two 30-item alternate forms of a conventional test and half of whom received two 30-item alternate forms of a Bayesian adaptive test. Both types…

The purpose of this paper is to compare the utility of the information yielded by the classical and latent trait psychometric models when they are used to examine the psychometric qualities of an instrument designed to assess school-related stress. The instrument, known as the School Situation Survey (SSS), is described, and efforts to determine…

The Myers-Briggs Type Indicator (MBTI) measures variations in normal personality. The validity of the measure has only recently been examined by analyses of the structure underlying MBTI responses; and these investigations have used exploratory factor analyses, rather than confirmatory factor analytic methods. A confirmatory factor analysis was…

This study investigated the nature of field independence by exploring the structure underlying responses to Forms A and B of a multiple-choice measure of field-independence, the Finding Embedded Figures Test (FEFT). Subjects included 302 students (52.7% male) enrolled in mathematics courses at a university in the southern United States. Students…

A literature review was conducted to determine the current state of knowledge concerning the effects of computer administration of standardized educational and psychological tests on the psychometric properties of these instruments. Students were grouped according to a number of factors relevant to the administration of tests by computer. Based on…

This manual makes accessible several widely used instruments for measuring perceptions of psychosocial characteristics of classroom environment among school students and teachers. Background information, scoring procedures, validation data, and preferred and short forms of the Learning Environment Inventory, My Class Inventory, Classroom…

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…

Based upon prior research in the College of Business and Public Administration and the first year of the university testing program at an upper division, midwestern university, implications for testing of older transfer students are drawn. Students should be tested before, or during, their first term of academic history. If remediation is not…

The test reliability of two tests of family functioning--the Family Environment Scale (FES) and the Family Adaptability and Cohesion Evaluation Scales (FACES-II)--was studied in 111 Anglo American, Black American, and Mexican American Families. The sample included children in grades three to six, as well as adults. The FES was administered to the…

A series of studies carried out in Aberdeen, Scotland and Lancaster England is used to illustrate changing interests in the area of personality and learning. The early studies looked for general relationships, adopting a psychometric approach. Recent work has been focused more on the process of learning, particularly in higher education, and on…

Research has recognized that anxiety may exert a debilitating effect on students' academic performance; however, many studies of test anxiety have been limited by their failure to consider sex differences. Two studies were conducted to analyze sex differences of the Test Anxiety Scale (TAS) and achievement correlates and to validate a factor…

A description of the perceptual/psychomotor ability requirements for performing the tasks of various Air Force career fields was sought. An analysis of the literature relating to taxonomies, measurement considerations and job analyses yielded a taxonomy containing thirteen perceptual/psychomotor classes along with techniques for collecting the…
