Scores from the National Board Dental Hygiene Examination (NBDHE) served as the criterion variable in a comparison of the predictive validity of the Dental Hygiene Aptitude Tests (DHAT) and the ACT Assessment tests. The DHAT-Science and Verbal tests combined to produce the highest multiple correlation with NBDHE scores. (Author/DWH)

The California Achievement Test and Degrees of Reading Power tests were administered to students to determine the relationship between the instruments as measures of reading. It was concluded that either test may be used to make valid predictions to the other by use of locally constructed conversion tables. (Author/DWH)

The Computer Attitude Scale evaluates student attitudes concerning computers and computer-related programs. This study examines the reliability and factorial validity of the scale and its subscales. Data indicate the instrument is an effective and reliable method of measuring secondary school students' attitudes toward learning about, and using,…

The development and validation of an instrument to assess the needs and concerns of elementary school substitutes are described. A literature review identified nine categories of needs for substitute teachers. A factor analysis of item responses for a sample of elementary school substitutes corroborated the existence of nine underlying factors.…

Scores derived from the Coopersmith Self Esteem Inventory (SEI), Tennessee Self Concept Scale (TSCS), Slosson Intelligence Test (SIT), and Rotter's Internal-External Locus of Control (LOC) Scale were analyzed. Significant correlations were obtained between scores on these instruments. Race and SIT scores and age and LOC scores were also…

Data from surveys of university students that utilized the Approaches to Studying inventory were analyzed to test the hypothesis that a curvilinear relationship exists between learning strategies and academic grades. However, none of the non-linear regression models investigated improved significantly on the explanatory power provided by the…

The study was conducted to determine the construct validity of the Teacher Occupational Stress Factor Questionnaire (TOSFQ). The instrument was administered to a sample of elementary school teachers of the gifted. Four factors emerged and were renamed as a result of this study. (Author/DWH)

A model of examinee behavior was used to generate hypotheses about the operation of true-false scores. Confirmation of hypotheses supported the contention that true-false scores contain an error component that makes these tests less reliable than multiple-choice tests. Examinee response style may invalidate a total true-false score. (Author/DWH)

A quantitative way of measuring peer tutor training programs and peer tutor effectiveness is presented. The evaluation of a peer group training course at Baruch College (City University of New York), for which this questionnaire was developed, is described. This measure is adaptable to most higher education peer tutoring programs. (Author/BS)

Data analysis of test scores from 278 undergraduates on three untimed course-based objective examinations yielded no linear or curvilinear relationships between completion speed and performance on individual tests or between average completion speed on three tests and total score. Results suggest that completion speed is unrelated to performance.…

The Regression Model, popular in selection bias research, is proposed for use in item bias detection, providing a common framework for both types of bias. An empirical test of this new method, now called the Regression Bias method, and a comparison with other commonly used item bias detection methods are presented. (Author/BS)

Some suggestions for measuring marginal symmetry in agreement matrices for categorical data are discussed, together with measures of item-by-item agreement conditional on marginal asymmetry. Connections with intraclass correlations for dichotomous data are noted. (Author)

This study analyzed the Tennessee Self Concept Scale (TSCS) scores from three subject groups (one clinical and two college samples). Five separate item pool arrangements were organized from the TSCS to assess its validity and related issues. The utility of the TSCS in applied settings is discussed. (Author/BS)

A comparison of measures of association for 2x2 data was carried out by computer analysis. For each of 1,539 tables, 14 measures of association were calculated and evaluated. A measure based on the odds-ratio (Chambers, 1982) was most accurate in capturing the rho underlying a majority of the tables. (Author/BW)

This study investigated the empirical effects of two parameters in the randomized response design upon the estimated proportion of individuals possessing the sensitive characteristic: (1) the probability of selecting the sensitive question and (2) the proportion of individuals possessing the nonsensitive characteristic.
