Two experiments were reported that aimed at investigating the development of spatial analysis of hierarchical patterns in children between 3 and 9 years of age. A total of 108 children participated in the drawing experiment, and 224 children were tested in a force-choice similarity judgment task. In both tasks, participants were exposed to…

The longitudinal interrelations among age, visual and auditory short-term memory, and the concrete operational tasks of class inclusion and combinatorial reasoning were investigated over four testing occasions in a sample of 134 students, initially ranging from 5 to 12 years in age. The Piagetian task battery involved placement of colored…

Elementary school teachers and their supervisors were surveyed to determine their perceptions of supervisory tasks. (GW)

A total of 72 kindergarteners received eight conservation of number trials which varied in the degree of perceptual support for one-to-one correspondence (four levels) and type of stimuli (toy animals or corks). A between-subjects variable was the method of presentation (standard conservation presentation, a partially fixed array, or a fixed…

The purpose of this study was to determine whether or not significant differences exist between teachers and principals in their perception of who should take the leadership role in handling specific tasks in an elementary school setting. A total of 55 such tasks, representing six major categories of activity, were included in a survey distributed…

This paper presents a study designed to clarify the role of perceptual-attentional factors in the development of conservation, and relates the results to procedures for assessing conservation. Subjects were 192 first and second graders. The number and type of perceptual cues in the conservation of liquid quantity task were systematically varied.…

Various counting tasks were presented to 24 congenitally, totally blind children, aged 3-13, to determine the behaviors employed to ensure accurate counting. Three dimensions of tactile strategies were found, including "scanning,""organizing," and "partitioning." A developmental progression in the ontogenesis of each…

The relation between field independence-dependence and creativity was investigated in 40 fourth graders equally divided by sex. The measures used were the Children's Embedded Figures Test, several verbal and figural subtests from the Torrance Tests of Creativity, and the Peabody Picture Vocabulary Test. No significant Pearson correlations were…

Presented are Parts 1 and 2 of a teaching guide designed for use in the United States Dependent Schools in the European Area. It provides a developmental, task analysis approach for teaching elementary and secondary level mentally retarded and learning disabled students. Included in Part 1 are steps for use of the guide, an explanation of task…

Performance of school children in regard to their standing and reach postures are described with dimensions given on the limits of their performance only. The facts of task performances are presented for the following tasks--(1) seeing into a shelf, (2) reaching into a shelf, (3) drawing on a vertical surface, (4) sitting or standing while…
