A literature review of information processing and internal and interdepartmental library communication is included. Face-to-face and telephone communication dominated as choice of medium. Public service and…

Provides a short BASIC program, RANVAR, which generates random variates for various theoretical probability distributions. The seven variates include: uniform, exponential, normal, binomial, Poisson, Pascal, and triangular. (MVL)

The use of base rate information by professionals (n=161) and undergraduates (n=97) in deciding probability of sexual abuse was studied. While professionals better prioritized the evidence of abuse in hypothetical cases based on sexual behaviors, both groups misestimated the probability of abuse for a child from a population with a known base rate…

Monte Carlo techniques are used to examine the power of the "B" statistic of R. L. Brennan (1972) to detect negatively discriminating items drawn from a variety of nonnormal population distributions. A simplified procedure is offered for conducting an item-discrimination analysis on typical classroom objective tests. (SLD)

Reports on a study that analyzed and compared a restricted set of full-text articles from a sub-specialty of biochemistry in terms of co-occurrences and co-absences of words. The consequences for the lexicographical approach to generating artificial intelligence from scientific texts are discussed. (JAK)

Beliefs of 153 academically talented students in grades 3 through 11 about the stability of intelligence paralleled a normal distribution. About half had easily modified views, and 9% were at risk of underachievement based on self-perceptions of low ability and the belief that intelligence is stable. (SLD)

The relationship between the library and its patrons is damaged and the library's reputation suffers when returned items are not checked in. An informal survey reveals librarians' concern for this problem and their efforts to combat it, although few libraries collect objective measurements of errors or the effects of improvement efforts. Brigham…

Comparable statistics on education, training and skills are not only used by research and analysis to provide explanation and evidence of the functioning of European labour markets and of education and training systems, but also to construct indicators comparing EU Member States, comparing the EU with competitors and assessing the achievement of…

"Safe, Healthy and Ready to Succeed: Arizona School Readiness Key Performance Indicators" presents a set of baseline measurements that gauge how well a statewide system of school readiness supports is addressing issues that affect Arizona children's readiness for school. The Key Performance Indicators (KPIs) measure the system, rather…

How do students react to being told that they have failed a test required for high school graduation? In 2000, 7,989 students were wrongly informed that they had failed the Minnesota Basic Standards Test in mathematics. The authors conducted a survey of 911 of these students to assess the psychosocial impact of this event. More than 80% of…

The hypothesis of positive skew in distributions of response to creative thinking tasks was studied. Data were obtained from examinees' responses to problem-solving tasks in three published studies of creative thinking. Subjects included 23 fifth graders (12 females and 11 males), 29 high school students (10 females and 19 males), and 47 female…

A cubic spline method for smoothing equipercentile equating relationships under the common item nonequivalent populations design is described. Statistical techniques based on bootstrap estimation are presented for choosing an equating method/degree of smoothing. Smoothing decreases the estimate of random error but results in an increase in…

Any voucher program that is going to have a major impact on a public education system is likely to require an expansion of private schools in order to accommodate increased demand; however, little is known about where private schools open and therefore how a major voucher program might affect private school availability in various communities.…

The job analysis study described in this report was conducted to serve as one of the bases for documenting the content validity of the Praxis II Subject Assessment in German. The purpose was to describe the most important knowledge and skills domains needed by newly licensed (certified) German teachers in order to perform their jobs in a competent…

This manual is a first effort to begin to identify, describe, and develop procedures for assessing various aspects of digital reference service.
