For 235 ninth-grade students, intercorrelations of Guilford's structure-of-intellect (SOI) tests and of three measures of critical thinking were factor analyzed. The study reveals the viability of using SOI constructs involving cognition and evaluation of semantic content as likely explanatory components of critical thinking. (Author/AL)

This research focused on verifying the impacts of Inclusion on both students with disabilities (SWDs) and their Regular Ed classmates. High school students (n = 364) within inclusive classes completed surveys reflecting their perceptions of the effectiveness of the learning environment and the attitudinal impacts of Inclusion. Results documented…

The purpose of this study was to conduct psychometric testing on the Chinese version of the decisional balance scale (CDBS) with Taiwanese seventh, eighth, and ninth graders who were recruited from the Taipei metropolitan area. A random cluster sampling method was used with 554 adolescents between the ages of 13 and 17 years. Factor analysis…

Objective: To ascertain the association between pubertal stage and deliberate self-harm. Method: Cross-sectional survey of 12- to 15-year-olds in 300 secondary schools in the U.S. state of Washington in February-April 2002 and the Australian state of Victoria in June-August 2002. A total of 3,332 students in grades 7 and 9 provided complete data…

The purpose of this study was to investigate statistical relationships between gender and Alberta Achievement Testing Program scores. Achievement test scores from grades 3, 6, and 9 in all subject areas were investigated during a four-year period. Results showed statistically significant positive correlations between gender and scores in most…

Comparative validity data for the Career Ability Placement Survey and the General Aptitude Test Battery relative to predicting course marks are presented for a sample of ninth grade students. The pattern of correlations between school grades and conceptually similar tests in the two measures was highly similar. (Author/JKS)

Spatial abilities are fundamental to human functioning in the physical world. Spatial reasoning allows people to use concepts of shape, features, and relationships in both concrete and abstract ways, to make and use things in the world, to navigate, and to communicate. Surgeons, pilots, architects, engineers, mechanics, builders, farmers, trades…

Information processing was measured in terms of reaction time and movement time to stimulus displays which differed in amount of information transmitted. Only reaction time increased as a linear function of number of bits in the stimulus display. Both show individual differences which significantly correlated with intelligence. (Author/RD)

The decline of physical activity during adolescence is not well understood. This prospective study followed 969 Taiwanese students from eighth to ninth grade and examined their physical activity-related cognitions, interpersonal influences, and behavior of physical activity across the grade transition. Gender differences were found in the effects…

While a negative effect of ability grouping on the achievement of students assigned to lower ability groups has been noted frequently, no empirical research has looked at the effects on academic achievement of moving a student from one ability group level to a higher or lower group. In this paper, I report results of an empirical study that…

A study investigated possible causes of high percentages of students failing the Ohio Ninth Grade Proficiency Test (ONGPT) in mathematics. The validity of the math test may be questionable. The reading and math scores of over 200 ninth-grade students from a rural school in northwest Ohio were used as a basis. Only scores from the fall of 1991,…

A study was conducted to establish the construct validity of measures designed to assess topical knowledge. Thirty-one ninth-grade students and 44 third/fourth-grade students were interviewed to ascertain their knowledge about 4 topics; 2 weeks later they responded to 3 tests of topical knowledge. Results were analyzed quantitatively and…

This article describes an investigation making connections between the time on an analog clock and the angle between the minute hand and the hour hand. It was posed by a middle school mathematics teacher. (Contains 8 tables and 6 figures.)

Psychomotor performance is fundamental to human existence. It is important in many real world activities and nowadays psychomotor tests are used in several fields of industry, army, and medical sciences in employee selection. This article tries to define psychomotor activity by introducing some psychomotor theories. Furthermore the…

A total of 194 students, eight intact classes of ninth and tenth graders, were examined for changes in their writing skills after it was determined that significant changes in reading skills had occurred in the experimental groups (four of the eight classes). When the writing samples were analyzed for overall quality, syntactic density, T-unit…
