The discrete mathematics topics of trees and computational complexity are implemented in a simple reliability program which illustrates the process advantages of the PASCAL programing language. The discussion focuses on the impact that reliability research can provide in assessment of the risks found in complex technological ventures. (Author/JJK)

National Assessment of Educational Progress writing sample essays from 1988 and 1990 (495 and 599 essays) were subjected to computerized grading and human ratings. Cross-validation suggests that computer scoring is superior to a two-judge panel, a finding encouraging for large programs of essay evaluation. (SLD)

Scores from 324 Louisiana schools on the Louisiana Graduation Exit Examination and a within-school split sample of 255 schools indicate that a single subject or grade provides a less consistent and more narrow perspective on school effectiveness than a subcomposite made up of 2 subject areas. (SLD)

Investigated correlations between two intelligence measures for exceptional children. Corrected correlations between the tests indicated differences with correlations reported in one manual. Relationships were generally higher than those reported elsewhere. Implications are discussed, especially those involving the use of correlations between…

Nine comprehensive observations were conducted of 24 preschoolers (8 with disabilities) in free play settings, with social behavior categories based on the work of Strain. Comparison of partial and complete observational records demonstrated that at least five observations were required to represent the children's social behavior adequately.…

It is proposed that proportional reduction in loss (PRL) be used as a theoretical basis to derive, justify, and interpret reliability measures to gauge reliability on a zero-to-one scale. This PRL approach simplifies the interpretation of existing measures (e.g., generalizability-theory measures). (SLD)

An investigation of the effects of integrative and instrumental motivation on the learning of French/English vocabulary demonstrated that both types of motivation facilitated learning, and that computer administration of an attitude/motivation test battery did not detract from the internal consistency reliability of the subscales. (19 references)…

A peer evaluation experiment in a British polytechnic institute found peer grading correlated positively with teacher grading. A survey of participants (n=70) found that five advantages of peer marking had been achieved and that students believed their work had been marked fairly and the marks should count toward final grades.

This study examined head rotation, shoulder extension and rotation, ankle plantar and dorsiflexion, hip flexion, and sit and reach (SR) in 80 adults, aged 45-75, to identify flexibility factors. No single measurement indicates loss of flexibility at all joints, but SR tests are found to be more reliable than others. (SM)

A brief overview is provided of the Conger-Lipshitz approach to estimating the reliability of a profile or test battery. A computational example from a recent study shows how canonical reliability can be obtained through existing statistical software. (SLD)

This study describes validation data for qualitative and quantitative writing measures useful with a full range of students, including special education students, in grades three through five. The study looked for consistent administration and scoring, sensitivity in differentiating groups of students, relation to other accepted assessments, and…

Used a 61-item questionnaire to measure the quality of curricular processes at 4 curriculum conferences. Participants' estimation of the process revealed high curricular quality at all four conferences. Findings suggested that curricular intensity, rational argumentation, interaction, and ego involvement were greatest at the third conference. (11…

The Groningen Social Disabilities Schedule for the assessment of social dysfunctioning of psychiatric patients is described. The measure is based on social role theory and the hierarchy in social disabilities as well as compatibility with the International Classification of Impairments. The semistructured measure allows for posing supplementary…

A preprinted evaluation form and generalizability theory were used to judge the reliability of student grading of their peers' papers. Findings suggest that students can be consistent and fair in their assessments. Student practice in peer evaluation will help develop the management skill of employee evaluation. (JOW)

This study examined the relationship between scores on the Behaviour Disorder Scale (BDS) and other assessments of challenging behavior in 100 adolescent and adult Australians with intellectual disabilities. The study found that the BDS was reliable and could be used to identify people with intellectual disabilities who exhibit behavioral…
