The authors developed, tested, and validated a set of student self-ratings, teacher ratings, and performance assessment instruments designed to measure generalizable reasoning skills of students enrolled in secondary vocational programs. They were found to be sufficiently reliable and valid indicators of functional learning strengths and…

The study evaluated the psychometric properties of reliability and construct validity of the Attitude Toward Mainstreaming Scale (ATMS) in an Australian context. It was concluded that the scale is both reliable and factorially valid in an Australian context. (Author/DB)

Evaluated quasi-experimental simulation technique designed to measure impact of individual differences in managerial styles on executive performance. Tested 20 simulation-based measures for reliability and validity. Data from two samples suggest that this quasi-experimental simulation technology may be useful in assessing managerial styles not…

The meanings of reliability and validity as they apply to standardized measures are used as a framework for applying the concepts of reliability and validity to authentic assessments. This article sees reliability as scorability and stability, whereas validity is seen as students' ability to use knowledge authentically in the field. (DB)

An examination of the extent to which scores on the Stuttering Severity Instrument (SSI) for Children and Adults, Third Edition, accurately reflect 10 judges' observations of stuttering behaviors found that SSI scores obscured the wide range of judges' raw counts and did not accurately reflect the observational data from which they were derived.…

Predictive validities of computer aptitude and computer anxiety were studied using nonprogramming computer performance as the criterion variable for 162 young adults. Effects of computer anxiety on performance were negligible, and computer aptitude yielded uncertain results. The measurement instruments' reliability was also reported. (SLD)

Reliabilities and information functions for percentile ranks and number-right scores were compared using item response theory, modeling standardized achievement tests. Results demonstrate that situations exist in which the percentage of items known by examinees can be accurately estimated, but the percentage of persons falling below a given score…

Measurement fidelity (reliability, factor structure, and validity) of Aschenbach's Youth Self-Report scale was studied with 226 adolescents at a psychiatric hospital. Findings confirm convergent validity and reliability of four of the measure's seven narrowband syndromes, and seven meaningful subdimensions were extracted from the other three…

An example application of portfolio assessment was developed and the model and estimates of reliability derived from the literature were then used to estimate the characteristics of an operational large-scale portfolio assessment program. Costs were estimated to put results in a realistic context. (SLD)

Eight-item revision of the UCLA Loneliness Scale was administered to 2,614 students, aged 11-14. Loneliness did not differ by age or between Anglo- and Mexican-American students, but was higher for girls than boys in each ethnic group. Principal components factor analysis and correlations with other related measures indicate good reliability and…

A five-year curriculum evaluation project is described that treated students' course ratings, examination reliability coefficients, and item-discrimination data as a battery of data points for determining annual revision efforts. Histograms were constructed to make valid demonstrations of successful efforts immediately comprehensible to faculty.…

Evidence supporting the use of a revision of the Opinions Relative to Mainstreaming scale, called Opinions Relative to Integration of Students with Disabilities, is presented. Scale testing with 376 professionals revealed satisfactory item characteristics, adequate reliability and homogeneity, and initial support for construct validity. The scale…

The behavior of each of 120 students in grades 9-12 was rated by 2 of the student's teachers using the Revised Behavior Problem Checklist. Results indicated a generally low to moderate degree of relationship among teacher ratings. It is recommended that clinicians collect behavioral ratings from many raters before reaching diagnostic conclusions.…

The design of a valid and reliable test of test-wiseness is reported: a 33-item multiple-choice instrument with 4 subscales trialed with several groups of English-as-a-Second-Language students. Findings indicate differential skills in test-taking; some learner scores are influenced by skills that are not the focus of the test. (13 references)…

The Miller Assessment for Preschoolers, intended for children ages 2-5, is designed as both a screening and a diagnostic assessment, measuring neuromaturational variables, coordination, language, memory, problem solving, and visual perception. This review examines test administration, summation of data, standardization, reliability, and validity,…
