Describes an investigation of the relationship between the levels of interlinker consistency obtained among a group of full-text databases in which internodal links were inserted, and the effectiveness of searches carried out in those databases. Topics include interindexer consistency and retrieval system evaluation. (Author/LRW)

Includes four articles that discuss LibQUAL+[TM], a collaborative effort of the Association of Research Libraries and Texas A&M University responding to the need for greater accountability in measuring the delivery of library services to research library users. Discusses the reliability of LibQUAL+[TM] scores in measuring perceived library…

Patterns of relationships were explored among developmental age, teacher ratings of global engagement, and observed engagement for 9.5- to 63.6-month-olds. Analysis revealed two uncorrelated patterns of relationships: (1) a positive relationship between developmental age and high levels of engagement and a negative relationship with lower…

The researchers in this study examined the association between adaptive and maladaptive dimensions of perfectionism and self-esteem. Confirmatory factor analysis and structural equations modeling were used to develop and test a model derived from theoretical links between perfectionism and self-esteem. Path models revealed that adaptive…

This paper presents a bidding strategy that may be incorporated into case-intensive courses. The purpose of the bidding process is to equitably distribute credit when students are assigned cases of differing degrees of difficulty. The paper also collects data to help answer a basic research question regarding this device: Is there evidence of…

The present study evaluated the criterion validity of the aggregated tasks of basic cognitive processes (TBCP). In age groups from 6 to 19 of the Woodcock-Johnson III Cognitive Abilities and Achievement Tests normative sample, the aggregated TBCP, i.e., the processing speed and working memory clusters, correlate with measures of scholastic…

Purpose: This study aims to provide substantive data on the effectiveness of the total-student-body approach to school-based conflict resolution training. The authors investigated the effectiveness of the Peacemakers (D. W. Johnson & Johnson, 1995) program, a total-student-body conflict training program taught bilingually to all students in a…

This work provides a correlation study of the role of the following cognitive variables on problem solving in elementary physical chemistry: scientific reasoning (level of intellectual development/developmental level), working-memory capacity, functional mental ("M") capacity, and disembedding ability (i.e., degree of perceptual field…

Within the scope of a double-blind, placebo-controlled, crossover medication study, the Diagnostic Assessment of the Severely Handicapped-II (DASH-II) was evaluated as a measurement for determining the effectiveness of the medication risperidone in treating the problem behaviour of 21 people with intellectual disabilities (ID). Participants…

The purpose of this study was to determine the relationship between reading achievement and parental involvement for sixth grade middle school students. The participants were forty-eight sixth grade students who completed parental involvement surveys. The parents of these students also completed a parental involvement survey. The results of the…

Websites were retrospectively analysed to study the effects that technological advances in web design have had on accessibility for persons with disabilities. A random sample of general websites and a convenience sample of US government websites were studied and compared for the years 1997-2002. Web accessibility barrier (WAB) and complexity…

The goal was to study the impact of a teacher-directed and a child-directed pretend play on cognitive performance in a mixed-age environment. Twenty-six observations were performed on fifty-one kindergarten children with a mean age of 4.6 years (age span from three to six years) in two mixed-aged classrooms. Data were collected regarding…

Sixteen percent of children 6-11 years of age were classified as overweight in 1999-2002, four times the percentage in 1965. Although poverty has traditionally been associated with underweight as a result of poor diet, researchers have recently pointed to a paradox in the U.S., which is that low income and obesity can coexist in the same…

In this article, we examine the role of visuospatial cognition in chemistry learning. We review three related kinds of literature: correlational studies of spatial abilities and chemistry learning, students' conceptual errors and difficulties understanding visual representations, and visualization tools that have been designed to help overcome…

The primary purpose of this study was to examine the relationship of teacher retention to teacher education programs and state-mandated teacher certification examinations (PD exam). Identified participants completed either a traditional field-based teacher education program or emergency permit program and had passed a professional development…
