Results are reported from a study that investigated the correspondence between two methods used to assess differential item functioning (test item bias). The study also explored the influence of sample size on the two procedures. Although agreement between the two procedures was generally good, the Rasch procedure was more reliable. (IAH)

This study found that the restructured National Board Dental Examination Part II is a reliable test assessing a full range of cognitive behaviors, and a unidimensional test of comprehensive general dentistry, suggesting better testing of knowledge and problem-solving skills than on the traditional examination. Performance on the pilot and…

Compares reading-disabled students' instructional levels yielded by the Ekwall Reading Inventory and the Metropolitan Achievement Test. Finds that both instruments provide instructional-level designations to help place students in appropriate materials but little correspondence between the instructional levels of the two measures. Suggests that…

Discussion of structural knowledge assessment for large groups focuses on the features of a "KNOT" computer program which uses a network similarity index (NETSIM) to compare novice and expert concept maps. Treatment in three high school physics classes investigated reliability as well as content, construct, concurrent, and predictive…

Projective methods were used to explore maternal perception and interpretation of infant's emotional expressions during the third trimester of pregnancy and 3 months postpartum. Results revealed that mothers interpreted infant emotions overwhelmingly in positive terms at both times; findings suggest consistency in maternal interpretation across…

Compared reliability of three widely used child protective service risk-assessment models (one actuarial, two consensus based). Found that, although no system approached 100% interrater reliability, raters employing the actuarial model made consistent estimates of risk for a high percentage of cases they assessed. Interrater reliability for the…

Responses to the 1999 Youth Risk Behavior Survey including suicide ideation, attempt, medically treated attempt, and six problem behaviors were analyzed. Youth across the spectrum ideated. Overwhelmingly, the 17% of youth with more than three problem behaviors were the youth who acted; they accounted for 60% of medically treated suicidal acts.…

Several analyses were conducted on data from samples of adults between 18 and 58 years of age who completed the same cognitive tests after an interval ranging from less than 1 week to 35 years. Because the retest interval varied across individuals, it was possible to determine the length of time needed before the gains associated with a retest…

Purpose: The purpose of this study was to compare judgments of stuttering made by students and clinicians with previously available judgments made by highly experienced judges in stuttering. Method: On two occasions, 41 university students and 31 speech-language pathologists judged the presence or absence of stuttering in each of 216 audiovisually…

ACT college test publisher provided scores. On average, non-homeschoolers performed better than homeschoolers, by about two items, out of sixty items, on the ACT mathematics test that was analyzed. This result may be due to the different teaching/learning media used in teaching each of the two groups, to different teacher/student interaction, or…

e-Learning is bringing training to the attention of upper management in a way that other learning technologies have never done. Web-based training will remain predominant to the design and delivery of workplace learning in the 21st century because of its advantages over traditional classroom-based training. A comprehensive framework that…

The purpose of this study was to investigate the effectiveness of DISCOVER, a performance- based assessment in identifying gifted Lebanese students. The sample consisted of 248 students (121 boys, 127 girls) from Grades 3-5 at two private schools in Beirut, Lebanon. Students were administered DISCOVER and the Raven Standard Progressive Matrices…

The L statistic of E. B. Page (1963) tests the agreement of a single group of judges with an a priori ordering of alternative treatments. This paper extends the two group test of D. W. Leitner and C. M. Dayton (1976), an extension of the L test, to analyze difference in consensus between two unequally sized groups of judges. Exact critical values…

Six sociometric measures were evaluated on a sample of 85 four-year-olds from three preschool and day care centers. Stability, intercorrelations, and accuracy of classifying rejected children were compared for measures of social preference, social impact, peer ratings, alternative status, and positive and negative nominations. Test-retest…

Decision making about an observational recording system for family interaction research is crucial. Alternative coding-recording methods and combinations thereof are discussed, including: (1) paper-and-pencil on-site method; (2) video-tapes; (3) paper-and-pencil and mechanical coding devices; (4) transcripts; and (5) transcripts combined with…
