This study examined five subscales of the Pennsylvania Educational Quality Assessment self-concept scale, composed largely of items from the Coopersmith Self Esteem Inventory, in terms of socioeconomic status (SES) and sex differences in internal consistency, stability, across time changes in means, and relationship with achievement. In general,…

The Student Orientations Survey (SOS) is a research inventory designed to assess students' expressed attitudes regarding curricular-instructional policies, their views on preferred modes of learning, student-faculty roles, etc. The SOS provides a means of profiling students' general orientations toward various philosophies, purposes, and processes…

Empirical results are presented as regards the implementation of a latent-trait psychometric model by means of conditional maximum likelihood estimation. Items are scored polychotomously into varying numbers of nominal categories and the test and item characteristic curves and information functions are examined. It is concluded that scoring items…

It is argued that early childhood education programs should be evaluated in terms of criteria other than measurement and testing procedures. Programs should be judged on criteria such as responsiveness to clients--the children, parents, and communities they serve. Teachers trained in observational and evaluative techniques should conduct ongoing…

Results of three studies based on Stanford Achievement Test data collected during the National Achievement Testing Program for Hearing Impaired Students in Spring, 1971 are reported. Compared in the first study are performance patterns of hearing impaired students on the Intermediate I and Advanced batteries with patterns of hearing…

Companies have been accused of using tests as a means of maintaining unfair discrimination against groups which have already suffered from many forms of discrimination. It does not follow, however, that tests themselves merit condemnation. Employers who use tests do so because the information furnished by tests is valuable to them in making hiring…

The purposes of the study to determine psychometric characteristics of the Series Learning Potential Test, the effects of Learning Potential training on Series scores, and the relationship of Series scores to IQ, race, social class, and reading achievement. The Series Test was administered to students in 79 classrooms in five Connecticut towns…

The purpose of this study was to improve the reliability of the Sigel Cognitive Style Test. Post hoc analysis of ninety test protocols had indicated that the original thirty-five card test could be shortened to improve the test's reliability. This analysis also showed that males were responding to certain cards differently from females.…

Five-hundred dichotomously scored response patterns were generated with sequentially independent (SI) items and 500 with dependent (SD) items for each of thirty-six combinations of sampling parameters (i.e., three test lengths, three sample sizes, and four item difficulty distributions). KR-20, KR-21, and Split-Half (S-H) reliabilities were…

Four new methods of item analysis were used to select subsets of items which would yield measures of attitude change. The sample consisted of 263 students at Michigan State University who were tested on the Inventory of Beliefs as freshmen and retested on the same instrument as juniors. Item change scores and total change scores were computed for…

This paper, a revision of the original document, "Correcting Partial, Multiple, and Canonical Correlations for Attenuation" (see TM 000 535), presents the formula for correcting coefficients of partial correlation for attenuation due to errors of measurement. In addition, the correction for attenuation formulas for multiple and cannonical…

The correction for attenuation formulas for partial, multiple, and canonical correlation coefficients are discussed and the effects of measurement errors on these statistics are explored. The notation is standardized and the derivation extended where appropriate. It is shown that as the reliabilities of the predictors become more disparate, the…

The problem of the comparability of change scores is investigated. Change quotients and residual change scores are evaluated as alternative approaches and methods for estimating the true change and true score residual, the reliability of change scores and residuals, and procedures for constructing confidence intervals for residuals are explored.…

Designed to investigate the performance of American Indian youth on the "Wechsler Intelligence Scale for Children" (WISC) compared to the "Chicago Non-Verbal" (CNV) for the purpose of establishing validity and reliability of the measurement and appraisal tools, this study analyzed test data from 71 Indian youth (aged 11 to 15)…

Specially constructed "speeded" and "unspeeded" forms of a Reading Comprehension section of the Law School Admission Test (LSAT) were administered to regular center and fee-free center LSAT candidates in an effort to determine: (1) if the test was more speeded for fee-free candidates, and (2) if reducing the amount of…
