The author reflects on his experiences with standardized tests, emphasizing the dreadful consequences of our continued allegiance to them. In doing so, the author expounds on how public schools have kowtowed to a harmful societal preference for results regardless of processes, decision-makers’ desires to quantify learning, and the desires of textbook companies and test publishers to exploit schools for their own profit. As administrators and the public gauge teacher-effectiveness, they have neglected the needs of students and the realities teachers face. Teachers have to continually labor to find reasons to remain hopeful regarding their actions. 相似文献

A 6-month analysis of training-intensity distribution and physiological adaptation in Ironman triathletes 总被引：2，自引：2，他引：0
In the present study, we analysed the training-intensity distribution and physiological adaptations over a 6-month period preceding an Ironman triathlon race. Ten athletes (mean ± s: age 43 ± 3 years, mass 78.3 ± 10.3 kg, stature 1.79 ± 0.05 m) participated in the study. The study consisted of three training periods (A, B, C), each of approximately 2 months' duration, and four testing weeks. Testing consisted of incremental tests to exhaustion for swimming, cycling and running, and assessments for anthropometry plus cardiovascular and pulmonary measures. The lactate threshold and the lactate turnpoint were used to demarcate three discipline-specific, exercise-intensity zones. The mean percentage of time spent in zones 1, 2, and 3 was 69 ± 9%, 25 ± 8%, and 6 ± 2% for periods A-C combined. Only modest physiological adaptation occurred throughout the 6-month period, with small to moderate effect sizes at best. Relationships between the training volume/training load and the training-intensity distribution with the changes in key measures of adaptation were weak and probably reflect differences in initial training status. Our results suggest that the effects of intensity distribution are small over short-term training periods and future experimental research is needed to clarify the potential impact of intensity distribution on physiological adaptation. 相似文献

2007 data from LibQUAL+™ and the ACRL Library Trends and Statistics database were analyzed to determine if there is a statistically significant correlation between library expenditures and usage statistics and library patron satisfaction across 73 universities. The results show that users of larger, better funded libraries have higher expectations for information resource availability, but not higher satisfaction scores. Furthermore, the data show no significant correlation between library usage statistics and user satisfaction. The researchers conclude that the lack of expected correlations could be attributed to limitations in the LibQUAL+™ method of measuring patron satisfaction, or the difficulty of using the quantitative measurements found in ACRL statistics to try and accurately predict user satisfaction. 相似文献
