This study compared the Qualitative Scoring System for the modified version of the Bender-Gestalt Test and the Developmental Scoring System for the Bender-Gestalt Test in predicting performance on the Metropolitan Achievement Test. The subjects were 409 first through fourth graders from regular classes in a public elementary school. Both scoring systems correlated significantly with school achievement. However, the Qualitative system correlated higher than the Developmental system with all Metropolitan Achievement Test subscores. Tests for differences between correlations indicated that five of these comparisons were statistically significant.  相似文献

Each year thousands of children are evaluated or reevaluated utilizing the current edition of the Wechsler Intelligence Scale to determine their eligibility for gifted programs. The Wechsler Intelligence Scale for Children-III (1991) is new enough that only limited research is available on how it compares to the previously used Wechsler Intelligence Scale for Children-Revised (1974). The purpose of this study was to determine the comparability between the previously dominant intelligence scale, the WISC-R, and the revised WISC-III with gifted children. The results of this study indicate that the latest revision (WISC-III) and the earlier version (WISC-R) produce remarkably similar scale and subtest scores when administered under clinical conditions to gifted children. All 51 children determined eligible through the administration of one of these two Wechsler tests would have been eligible for services had the other test been administered. The Verbal and Performance scale IQ scores were within two points of each other across the two test administrations, while only a one-point difference existed between the Full Scale IQ scores. The Arithmetic, Comprehension, and Object Assembly subtest scores were in high agreement across the two administrations (p<.01). The level of agreement between some subtests across the two administrations suggests that clinical judgment is just as important as scores in considering who is eligible for gifted programs.  相似文献

The study of childhood stress provides a useful perspective for assessing children's emotional status. Thematic projective techniques, like the Children's Apperception Test (CAT), may be useful in exploring children's perception of stress. For this purpose, a need-threat analysis is recommended to identify those underlying needs and threats that are likely to make a particular event or situation important, and hence potentially stressful, to an individual child. This paper introduces a scoring system for the CAT based on the analysis of thematic data in terms of five need-threat binaries, which serve as scoring categories. Preliminary data on reliability are presented.  相似文献

This article discusses the status of workplace training in the United States, describes a model of how to conduct effective on-the-job training, and presents the results of a questionnaire based on a model designed to assess on-the-job training practices aboard Navy ships. The model views the on-the-job trainer as a coach who guides the trainee through a task using three steps: 1) assessment, 2) training, and 3) evaluation. The questionnaire was sent to over 5,000 shipboard supervisors; 2,321 responded. Results indicate that nearly 50% of the Navy supervisors who responded are not as effective as they could be. The implications of these findings for the civilian workplace are discussed.  相似文献

Several cognitive psychologists have written about the importance of placing instruction within “authentic” contexts that mirror real-life situations. They argue that knowledge learned in academic settings does not necessarily transfer to non-academic settings. Whether preparing performance technologists or instructional designers, educators must strive to create meaningful problem-solving contexts that enable students to define, and subsequently solve, real-world problems. In an attempt to address this issue we have modified the way we teach instructional design. This paper discusses a cognitive apprenticeship approach to teaching design, which incorporates elements of modeling, coaching, reflection, articulation, and exploration. We describe how these features are embedded within three phases (orientation, situated training/learning, and exploration) of an introductory instructional design course designed to move our novice designers along a continuum of expertise as they develop and refine their own professional design skills. Although the apprenticeship model described here specifically addresses concerns within the context of preparing instructional designers, we believe that this model can be adapted to address similar issues in the education of performance technologists.  相似文献

Obesity is a complex disease with multiple contributing factors.One of the most intensely studied factors during the past decade has been the gut microbiota,which is the community of all microbes in the intestinal tract.The gut microbiota,via energy extraction,inflammation,and other actions,is now recognized as an important player in the pathogenesis of obesity.Dysbiosis,or an imbalance in the microbial community,can initiate a cascade of metabolic disturbances in the host.Early life is a particularly important period for the development of the gut microbiota,and perturbations such as with antibiotic exposure can have long-lasting consequences for host health.In early life and throughout the life span,diet is one of the most important factors that shape the gut microbiota.Although diets high in fat and sugar have been shown to contribute to dysbiosis and disease,dietary fiber is recognized as an important fermentative fuel for the gut microbiota and results in the production of short-chain fatty acids that can act as signaling molecules in the host.One particular type of fiber,prebiotic fiber,contributes to changes in the gut microbiota,the most notable of which is an increase in the abundance of Bifidobacterium.This review highlights our current understanding of the role of gut microbiota in obesity development and the ways in which manipulating the microbiota through dietary means,specifically prebiotics,could contribute to improved health in the host,including musculo skeletal health.  相似文献
