This study replicated previous research that tested the validity of A. Biglan's classification scheme, a theoretical framework for empirically examining the differences among academic disciplines and classifying them according to three dimensions (hard-soft, pure-applied, life-nonlife). In addition, new data were used to attempt continued…

Three classifications of 6- through 12-year-old children (388 nonretarded, 115 educable mentally retarded, and 85 trainable mentally retarded) were evaluated on the public school version of the Adaptive Behavior Scale by their teachers. (Author/SBH)

Autism Behavior Checklists were completed for 52 autistic individuals (ages 2-31) and 62 nonautistic individuals, and data were analyzed using signal detection methodology. A single item (looks "through" people) combined with one of five other items discriminated as well as the sum scores, and further combinations did not improve…

This paper examines cognitive processing problems associated with attention deficit disorders (ADD) and their relationship to learning disabilities in elementary and secondary students. Children with ADD, medicated (N=20) and unmedicated (N=21), were compared on the Raven test of Progressive Matrices and other tests with children who had been…

The Autism Behavior Checklist was completed for 67 autistic and 56 mentally retarded and learning-disabled children (ages 6-15). The checklist was effective in classifying children when using either the full scale or only the more highly weighted items. Results did not support a single unidimensional scale or subdividing the checklist into five…

Research studies using booklet classification were implemented by the American College Testing Program to investigate the linkage between the National Assessment of Educational Progress (NAEP) Achievement Levels Descriptions and the cutpoints set to represent student performance with respect to the achievement levels. This paper describes the…

A recategorization system developed by Bannatyne to categorize subtest scatter from the Wechsler Intelligence Scale for Children-Revised (WISC-R) is used as an alternative to isolated analysis of each individual subtest. Reading disabled, learning disabled, and educable mentally handicapped students are categorized according to their performance…

We attempted to differentiate the family environments of youth with Conduct Disorder (CD) compared to youth with a depressive disorder. Participants were 34 adolescents from a residential treatment facility. The K-SADS-P was used to determine the youth's diagnosis, while their family environment was assessed by the Self Report Measure of Family…

Classification studies are important for practitioners who need to identify individuals for specialized treatment or intervention. When interventions are irreversible or misclassifications are costly, information about the proficiency of different classification procedures becomes invaluable. This study furnishes information about the relative…

Members of a group of hospitalized children under 4 years of age (48 under care for child abuse, 97 for accidents, 41 for failure to thrive, and 23 for ingestions) were matched individually on age, social class, and race with controls suffering from comparable acute medical conditions. A structured maternal and paternal interview yielded 63…

The unrehearsed performance of music, called "sight-reading" (SR), is a basic skill for all musicians. It is of particular interest for musical occupations such as the piano accompanist, the conductor, or the correpetiteur. However, up until now, there is no theory of SR which considers all relevant factors such as practice-related…

The purpose of this study was to investigate the differences among schools using student responses in the Trends in Mathematics and Science Study-1999 (TIMSS-99) data. Schools were classified into two groups based on eighth grade students' overall achievement in science. Two different discriminant function analyses were performed to distinguish…

A career typology is proposed as a method to evaluate teacher education programs. To test the viability of this approach, University of Minnesota graduate students majoring in elementary education were studied in terms of their declared career orientations. This investigation indicated that the graduate program in elementary education was oriented…

This study found that a linear discriminant function was able, with 73 percent accuracy, to distinguish between learning-disabled dropouts (n=213) and learning-disabled graduates (n=92). The discriminant function was composed of six variables--student ethnicity, reading ability, family intactness, family socioeconomic status, school transfers, and…

This book in intended to train students in reading a research report critically. It uses actual research articles as examples including both good and flawed studies in each category and provides interpretation and evaluation of the appropriateness of the statistical analyses in each study. Individual chapters usually include two sample studies and…
