This article describes the construction of a hierarchical taxonomy of metacognitive activities for the interpretation of thinking-aloud protocols of students in secondary education, who studied texts on history and physics. After testing an initial elaborate taxonomy on a restricted number of protocols by multiple raters, it appeared that the…

Three subtypes of autism based on social style have been proposed by Wing: active-but-odd, passive, or aloof. Previous research has shown evidence of an association between IQ and Wing subtype in untreated children and adults. Because IQ changes can accompany behavioral treatment, but often only for a subset of children, social subtype may be…

As one of the important stakeholders in the academic process, students and their preferences should be considered when the instructor selects the various course design features. Although students are not the only stakeholders in the academic process, their receptiveness to classroom instruction is clearly a central focus of that process. This…

It is generally accepted that Attention-Deficit/Hyperactivity Disorder (ADHD) results from a dysfunction of the central nervous system, which has led to a commonly held belief that environmental factors play little role in the behavioural problems of children identified as having ADHD. Therefore, the two studies reported in this article…

This paper discusses the principles underlying discriminant analysis and constructs a simulated data set to illustrate its methods. Discriminant analysis is a multivariate technique for identifying the best combination of variables to maximally discriminate between groups. Discriminant functions are established on existing groups and used to…

THE EFFECTS OF TEST ANXIETY AND TEST STRESS ON THE PERFORMANCE OF TWO DIFFERENT INTELLECTUAL TASKS WERE STUDIED. IT WAS HYPOTHESIZED THAT THE DESCRIPTIVE EFFECTS OF ANXIETY WOULD BE GREATER FOR DIFFICULT BUT SIMPLE TASKS THAN FOR COMPLEX BUT EASY TASKS, AND THAT SITUATIONAL STRESS WOULD BE MORE DISRUPTIVE FOR COMPLEX TASKS THAN FOR SIMPLE TASKS. A…

Linear classification functions (LCFs) arise in a predictive discriminant analysis for the purpose of classifying experimental units into criterion groups. The relative contribution of the response variables to classification accuracy may be based on LCF-variable correlations for each group. It is proved that, if the raw response measures are…

Longitudinal support was obtained for a positive relationship between cognitive and social development. From a large sample of kindergarteners, three groups of 12 children of comparable age and IQ were selected as displaying substantial, moderate, or no mastery of Piagetian concrete operations. From kindergarten through second grade, the social…

This study derives the economic costs of misclassification in nursing home patient classification systems. These costs are then used as weights to estimate the reliability of a functional assessment instrument. Results suggest that reliability must be redefined and remeasured with each substantively new application of an assessment instrument.…

A model of vocational decision status was developed, and an instrument was constructed and used to assess its three dimensions. Results demonstrated the utility of the model, supported the reliability and validity of the instrument, and illustrated the value of viewing vocationally undecided students as multiple subtypes.

Describes a study that measured the subject area and call number correspondence for the discipline of history at the Texas A&M University libraries. Considers the rise in interdisciplinary scholarship that challenges the frequent assumption that a correlation exists between topicality and call number range for collection management decisions.…

This study, involving 90 children with mental retardation and epilepsy, classified and compared level of retardation, neurological findings, and electroencephalograms with the quality of seizure control. No correlation was found between quality of control and any of these parameters. (Author/JDD)

The study addresses the relationship between values and occupations. Israeli workers (N = 652; mean age = 47; 43% male) in 32 occupations reported their values using the Portrait Value Questionnaire (Schwartz, Melech, Lehmann, Burgess, Harris, & Owens, 2001), and value scores were aggregated within occupations. Occupations were classified…

Five language assessment tests (LATs) are used for identifying children of limited English speaking ability in Texas: Basic Inventory of Natural Language; Bilingual Syntax Measure; Language Assessment Scales; Primary Acquisition of Language; and Schutt Primary Language Indicator Test. Interrelationships between LATs and relationships between the…
