Intended to serve as a manual for the developmental and evaluative activities of Project ABLE, this report presents the management and evaluation plan for instructional system development. Major emphasis of the plan is the formation of evaluative procedures drawing on student performance data as the primary source of feedback. To insure continuous…

This study is the fourth in a series of studies that have attempted to examine the relationship between two separate aptitude factors--associative memory and reasoning--to various performance criteria in a hierarchical learning task utilizing computer-assisted instruction. Two clear effects seem to emerge from the data. During learning, the…

This study was concerned with children's ability to conserve spatial relationships among objects in different arrangements, in the presence of projected changes in the observer's visual field. The objectives were: (1) to determine the effects of varying types of arrangement and number of objects in the arrangement on perspective ability…

This study was designed to investigate the effects of increasing levels of task complexity on the conditioned emotional response (CER) with human subjects (Ss). Three hypotheses were proposed: (1) the CER would increase as task complexity increased, (2) there would be sex differences between Ss with respect to the interaction between the CER and…

Many workers in the behavioral sciences and human factors technologies have expressed the need for better classification systems to understand and apply the vast amounts of data required about man for the performance of jobs and tasks. Reviews of existing classification systems, reported in previous technical reports in this series, disclosed more…

In this study, representational thought, which involves the child's ability to function in terms of nonpresent reality, is viewed within a cognitive-developmental framework. To see if disadvantaged children would function in the same way as advantaged children on tasks which required representational thought rather than verbalization, children…

Developmental Indicators for the Assessment of Learning (DIAL), a 1 year project in Illinois, funded through Title VI, to develop screening procedures for identification of prekindergarten children with potential learning disabilities is described. Discussed are evaluation of existing test instruments, which did not meet established criteria, and…

Nursery school children (N=64) received seven tests of conservation of number which varied in the type and number of perceptual supports for conservation. Most of the tests with these supports facilitated performance in comparison to the standard conservation test. Conservation appeared earlier than usual. There were significant effects of…

To investigate two measures which have been used to assess children's attention to stimulus dimensions, component selection, and dimension preference, both measures were administered to 38 3 1/2 to 5-year-olds and 20 5- to 6 1/2-year-olds. Seven to ten days after the dimension preference task was given. the component selection measure was…

Recent research has shown that certain stimuli are better remembered 6 months after initial exposure than after one week. An alternative explanation of these findings was tested. The explanation posited that the younger children "remember" as well at one week as 6 months later, but at the earlier testing many do not realize what aspect…

The study reported involved: (1) development of a concept learning task which embodied complex concepts similar to those included in elementary school curricula, and (2) investigation of the effects of type of thinking, abstract or concrete; grade levels, fourth, sixth, or eighth; and sex upon performance of human Ss with complex concepts of…

The concluding series of a research program designed to validate a battery of task indexes for use in forecasting the effectiveness of training devices is described. Phase I collated 17 task indexes and applied them to sonar training devices, while in Phase II the 17 index battery was validated, using skill acquisition measures as criteria.…

The paper covers the performances, skills, and kinds of knowledge demanded of an infantry rifle squad leader to maintain an organized and effective fighting unit under campaign conditions and to set an example as a leader for his men. It covers personal hygiene and field sanitation, the maintenance of minimal fighting and existence loads, water…

The research evaluates the effectiveness of a 'Concepts of CIC' program in improving performance on classroom monitoring exercises. The function of the combat information center watch officer (CICWO) course is primarily to train CICWOs in monitoring and evaluating. Two versions of 'Concepts of CIC' were administered to two groups of students in…

A total of 360 boys and girls from first through sixth grade were randomly selected and tested with an instrument developed in the Tacoma Public Schools, to determine: (1) differences in physical skills and fitness performance of pupils who received the services of an elementary physical education specialist and pupils who had not, and (2)…
