Individual empirical studies of motivation show little divergent validity of various factors and call for better measures, especially multidimensional instruments. The same conclusions were reached from a meta analysis of 40 motivation studies by Uguroglu and Walberg (1979). After a study of approximately 50 instruments that measured motivation constructs of social, emotional, and physical self-concept; locus of control; and achievement motivation, among others, a 23-anchored-item questionnaire using a five-point scale was developed that included these factors. The instrument was administered in May of the first and second year to 115 students in grades three through eight. The purpose of the research was to operationalize and field test a motivation instrument using multidimensional measures; also to consider whether any change would occur in the correlation of a multidimensional instrument to various achievement measures over unidimensional ones. Results of the study show the correlations of motivation to academic achievement, test-retest reliability, and the predictive validity of a multidimensional instrument.  相似文献

The present study investigated the problems that team members perceive to exist on multidisciplinary teams. One hundred forty-seven team members on 40 teams from four urban school districts completed a questionnaire that presented an exhaustive listing of potential team problems. Results indicated that the two most pressing areas of concern for urban, multidisciplinary team members were: too constrictive a set of team roles and goals, and teams functioning under extensive pressure with minimal support. Strategies to reduce problems and enhance team functioning are presented.  相似文献

The aim of the present study was to develop a system of tables to facilitate interpretation of the McCarthy Scales of Children's Abilities. Tables are presented that organize the McCarthy subtests according to Bannatyne's, Sattler's, and Meeker's systems of interpretation. In addition, tables that organize the McCarthy Scales into categories that reflect factors likely to influence various subtests are presented. These tables will provide a more structured approach to McCarthy interpretation and a straightforward empirical method for generating hypotheses regarding individual strengths and weaknesses in intellectual ability.  相似文献

The present study looked at whether special education placement decisions made by teams are superior to those made by individuals. The investigation was conducted in Puerto Rico to determine whether the benefits of the cooperative group process exist in another culture. Results indicated that teams in Puerto Rico generated significantly less variability (i.e., errors) in their placement decisions than did the same specialists acting independently.  相似文献

This study investigated the validity and reliability of the GymAware PowerTool (GPT). Thirteen resistance trained participants completed three visits, consisting of three repetitions of free-weight back squat, bench press, deadlift (80% one repetition maximum), and countermovement jump. Bar displacement, peak and mean velocity, peak and mean force, and jump height were calculated using the GPT, a three-dimensional motion capture system (Motion Analysis Corporation; 150 Hz), and a force plate (Kistler; 1500 Hz). Least products regression were used to compare agreeability between devices. A within-trial one-way ANOVA, typical error (TE; %), and smallest worthwhile change (SWC) were used to assess reliability. Regression analysis resulted in R2 values of >0.85 for all variables excluding deadlift mean velocity (R2 = 0.54–0.69). Significant differences were observed between visits 3-2 for bench press bar displacement (0.395 ± 0.055 m; 0.383 ± 0.053 m), and deadlift bar displacement (0.557 ± 0.034 m; 0.568 ± 0.034 m). No other significant differences were found. Low to moderate TE (0.6–8.8%) were found for all variables, with SWC ranging 1.7–7.4%. The data provides evidence that the GPT can be used to measure kinetic and kinematic outputs, however, care should be taken when monitoring deadlift performance.  相似文献

In 2004, a professional delegation of multicultural educators visited the People's Republic of China to explore how diversity issues are addressed and how students are prepared for entry into the international workforce. The delegation, sponsored by the People to People Ambassador Programs, observed numerous parallels to the American system of education, including the challenge of providing equity for students of minority cultures, especially those in poor rural areas, and the conflict between modernization and preservation of cultural heritage.  相似文献
