The present study attempted to develop a quantitative model using the WISC-R that could be used to predict those students most likely to be successful in gifted education programs. The study was conducted in two phases using two groups of gifted children. In phase one, 120 elementary students randomly chosen from a pullout program in a suburban school served as the subject pool. The subjects had varying degrees of success in the program. Phase one subject data were used to develop a quantitative model; phase two subjects were used for predictive purposes. Specific results in phase one yielded six maximally discriminant WISC-R subtests. These subtests were then used to predict at well above chance levels (87.8%) those students who were known to have been either marginally or highly successful in the program (n = 41). The present study goes one step beyond previous research by using these maximally discriminant subtests to predict program performance of gifted children. 相似文献

This study investigated current practices for screening new entrants to schools. A mail survey was conducted of 755 public‐ and private‐school districts in New York State to ascertain the procedures and instruments used to conduct kindergarten screening. Fifty‐one percent (385) of the districts responded. Thirty percent of the districts reported that they used locally developed screening instruments. The most widely used standardized instruments were the Developmental Indicators for the Assessment of Learning (DIAL‐R) (Mardell‐Czudnowski & Goldenberg, 1990), and the Brigance K & 1 Screen (Brigance, 1992). The great majority of respondents (95%) reported that screening is conducted on an individual basis, and in 45% of the districts, professionals spend more than 30 minutes in screening procedures with each child. On average, 3.58 different educational professionals in each district participate in screening procedures. About half of the districts reported that children identified as “unready” on the basis of screening procedures were referred for further evaluation; 19% of the districts advised parents to delay school entry for an additional year. Most districts (69%) reported that they were satisfied or very satisfied with current district practice. Implications for practitioners are discussed. © 2000 John Wiley & Sons, Inc. 相似文献

Our aim was to present a mathematical model of rowing and sculling that allowed for a comparison of oar blade designs. The relative movement between the oar blades and water during the drive phase of the stroke was modelled, and the lift and drag forces generated by this complex interaction were determined. The model was driven by the oar shaft angular velocity about the oarlock in the horizontal plane, and was shown to be valid against measured on-water mean steady-state shell velocity for both a heavyweight men's eight and a lightweight men's single scull. Measured lift and drag force coefficients previously presented by the authors were used as inputs to the model, whichs allowed for the influence of oar blade design on rowing performance to be determined. The commonly used Big Blade, which is curved, and it's flat equivalent were compared, and blade curvature was shown to generate a 1.14% improvement in mean boat velocity, or a 17.1-m lead over 1500 m. With races being won and lost by much smaller margins than this, blade curvature would appear to play a significant role in propulsion. 相似文献

The purpose of this study was to examine patterns of appraisal, coping, and coping effectiveness in sport. Ten players from a collegiate female volleyball team were interviewed on two occasions, first in the week before a provincial final playoff tournament and in the week following the tournament. Data were transcribed verbatim and subjected to content and idiographic analyses. Athletes generally did not predict or anticipate the stressors they actually experienced during the tournament. Subjective appraisals of effective coping were associated with consistency between proactive and actual coping attempts. Reported effective coping was associated with the attainment of personal performance goals and use of cognitive, behavioral, and emotional coping strategies in the absence of behavioral avoidance. Reported ineffective and partially effective coping was associated with not attaining personal performance goals, and the use of cognitive coping strategies with behavioral avoidance. Finally, older, more experienced athletes reported they coped better than younger, less experienced athletes during the tournament. 相似文献

This study provided initial validity evidence for multidimensional measures of coaching competency derived from the Coaching Competency Scale (CCS). Data were collected from intercollegiate men's (n = 8) and women's (n = 13) soccer and women's ice hockey teams (n = 11). The total number of athletes was 585. Within teams, a multidimensional internal model was retained in which motivation, game strategy, technique, and character building comprised the dimensions of coaching competency. Some redundancy among the dimensions was observed. Internal reliabilities ranged from very good to excellent. Practical recommendations for the CCS are given in the Discussion section. 相似文献
