Discussion of the use of scientific information disseminated in primary subject literature focuses on a study that developed a methodology for hypothesis testing that measured document obsolescence by means of citation analysis and content obsolescence by expert opinions and then compared the results. Information validity and information utility…

The reliability of residual scores created in the analysis of covariance in pretest-posttest designs, adjusted for a singe covariate, is compared with that of simple difference scores as relevant parameters vary. Little gain in reliability is created by analysis of covariance, which also suffers from reliability problems. (SLD)

After a mailed questionnaire and two follow-ups, hard-core survey nonrespondents were contacted to ask why they had not responded and what they would have answered had they responded. Results from 28 subjects indicate that efforts to pursue nonrespondents may be unnecessary, because bias resulting from nonresponse appeared minimal. (SLD)

Modifications are proposed to the recently developed method of comparing one-step M-estimators of location corresponding to two independent groups that provides good control over the probability of Type I error even for unequal sample size, unequal variances, and different shaped distributions. Simulation results reveal cautions required. (SLD)

A quantitative ethogram was developed for the zebra finch, using one-zero focal animal sampling on an ethologically comprehensive checklist of 52 behavioral items, and it was assessed for interobserver reliability and construct validity. Applying the quantitative methods of psychometrics allows verification of ethological theory and testing of…

Adult native speakers (L1) of Russian and advanced nonnative second-language (L2) speakers read Russian sentences on a computer and were asked to choose one of two inflected past-tense verbs in a forced-choice task. Verbs either matched or mismatched gender of the subject-noun phrase. Data suggested that L1 and L2 speakers may depend on common…

Discusses partial results of a research study designed to examine the support provided by a media-literacy program in the development of critical thinking of pupils aged 10 to 12 in Israel. Explains hypotheses tested, reports results of pretests and posttests, and compares results of low-achievement pupils versus high-achievement pupils.…

A feature shown to affect learners' performance on tests of spoken interaction is the gender of the person with whom the learner interacts. To test this hypothesis, 12 Japanese learners were interviewed, once by a man and once by a woman. Comparison of scores indicated that in all but one case the learners performed better when interviewed by a…

Draws attention to the validity of the Oakland School Board's resolution on Ebonics and to the value of English-as-a-Second-Language (ESL)-based approaches to teaching standard American English to speakers of other dialects. Demonstrates validity of comparisons made between monodialectal speakers of African-American language/Ebonics and ESL…

Describes two surveys of three libraries on a university campus, one conducted in 1987 and one in 1993, that investigated how library staff reacted to the library automation process. The hypotheses that were tested are discussed, and results are compared to a similar survey conducted in 1985. (LRW)

Investigated performance of 166 special education students (6 to 16 years) who had taken the Wechsler Intelligence Scale for Children-Revised (WISC-R) and later the Wechsler Intelligence Scale for Children-III (WISC-III). Results indicated a significant, positive correlation among global scales (p<.001). Findings suggest WISC-R and WISC-III…

Provides an overview of the Graduate Record Examination (GRE) Psychology test focusing on the scoring system for the GRE Psychology test, who prepares the test and how the test is prepared, and the usefulness of the GRE Psychology test. Explores some future directions for the test. (CMK)

Presented successive auditory time gatings of unfamiliar words--familiar, phonologically-related words and familiar, phonologically-unrelated words--to school-age children with and without specific language impairments (SLI). The groups did not differ significantly in the point at which they recognized familiar words, but the subjects with SLI…

Hispanic children with (n=148) and without (n=148) limited English proficiency were given the Naglieri Nonverbal Ability Test (NNAT; J. A. Naglieri. 1997a) and the Stanford Achievement Test-9th edition (SAT-9: 1995). The groups were selected from the NNAT standardization sample (N=22.620) and matched on geographic region, gender, socioeconomic…

This article reports the results of an investigation of the convergent criterion-related validity of two computer-based tools for scoring concept maps and essays as part of the ongoing formative evaluation of these tools. In pairs, participants researched a science topic online and created a concept map of the topic. Later, participants…
