A study designed to examine biological, sociological, and early maturational correlates of intelligence collected data prospectively, from birth to 15 years of age, on a sample of 987 black children. Multiple indicators of eight independent and three dependent variables were tested in a structural equation model. Altogether, clear sex differences…

Online searching is a complex problem solving task requiring the searcher to combine multiple sets into Boolean expressions. Since spatial ability has been correlated with problem solving tasks which involve abstract conceptual associations, this report argues that it is a significant factor in the information user's ability to both comprehend and…

This report explores an approach to item development and psychometric modeling which explicitly incorporates knowledge about the mental models used by examinees in the solution of items into a psychometric model that characterize performances on a test, as well as incorporating that knowledge into the item development process. The paper focuses on…

This issue of the journal contains abstracts and critical comments for 10 published reports on research in mathematics education. The reports concern children's school mobility and achievement, preservice teachers' sources of decisions, spatial visualization in boys and girls, rote versus conceptual emphases in teaching probability, using drawings…

This exploratory study was conducted to investigate the potential interaction between the media attribute, horizontal screen placement, and a learner's cognitive aptitudes, fluid ability, and visualization. The primary hypothesis tested was that low-ability learners who are without well-developed assembly and control operations should perform…

The Assessment Tool for Moderately Retarded Students in Academic Skills (1978) is designed for moderately retarded students (5-21 years) and mildly retarded students (3-14 years) who will be living in sheltered home and work settings. The assessment tool is based on a life centered curricular model concerned with developing--in a sequential…

This report presents two experiments that compared the performance of map experts to that of novices. Subjects (from the areas of geography, educational psychology, and sociology) were 13 university faculty members in experiment one and 12 undergraduate students in experiment two. Following a practice trial, the learning of a logical map and a…

This investigation analyzed sex-related and age-related differences on spatial visualization tasks, reasoning tasks, and mathematical problem-solving tasks; and the effects instruction in visual thinking would have on these differences. Students in fifth grade, ninth grade, and in college, were tested before and after twelve weeks of instruction…

Twenty-three computer assisted instructional packages for primary and intermediate/middle levels are listed with sources. Courseware was selected on the basis of high interest and probability of initial success with learning logic, science, social studies, and business areas represented. (DB)

Hearing-impaired adolescents (n=62) were evaluated on tests of specialized cognitive functioning. Variables noted were reading and mathematics achievement, speech production, etiology, and age at impairment onset. Performance was below average for verbal/sequential skills of the left cerebral hemisphere and average or above for the visuospatial…

Reading disability subtypes were determined in 50 neurologically impaired students (ages 11-19), with and without reading disabilities. Subtypes found primarily in the reading-disabled sample were anomic-language disorder, dysphonetic and mixed dysphonetic-dyseidetic, oral reading deficit, intermodal association deficit, and sequential relations…

This study investigates middle school mathematics students' views and interpretations of graphical representations as they use graphs to answer algebraic questions--specifically, questions that require them to extrapolate information from graphs. From data gathered in videotaped interviews, students' verbal responses were analyzed as well as any…

This thesis deals with using visual organizers as scaffolds in teaching English as a foreign language (EFL). Based on the findings of scientific researches, the review of literature explicates the effectiveness and fruitfulness in employing visuals organizers in EFL instructions. It includes the five following components. First, visual organizers…

Geographic information systems (GIS) are increasing in importance as a resource for collecting, managing, and analyzing data pertaining to a variety of business problems. Yet, the number of business schools that have incorporated GIS as a significant part of even one of their core business courses is quite small. Thus, little is known about how to…

This study assessed Chinese teachers' perspectives on why Chinese students perform well on spatial tasks. The study interviewed 17 male and 12 female teachers of Chinese language, math, science, and 6 other subjects, from elementary schools, high schools, and colleges of Beijing, China. The responses indicated that the Chinese teachers perceived…
