Three factors tied with secondary student success in content‐area reading are demonstrated: (a) validated teacher‐focused and student‐focused interventions, (b) integrated and comprehensive service delivery systems, and (c) well‐designed, data‐based professional developmental programs. Difficult challenges face secondary students with LD and their teachers with regard to these students’ participation and success in required general education classes. Recently, instructional methods and materials have been developed and validated for promoting these students’ success. Some of them focus on how general education teachers plan and teach their content‐area courses; others focus on giving students the strategies they need to respond independently to the demands of their courses. This article describes these instructional methods, a service‐delivery model for implementing these interventions in secondary schools, and professional‐development mechanisms and administrative support that must be in place for the model to be maintained effectively. 相似文献

Knowledgeable observers generally agree that students can give reasonably unbiased assessments of their classes, as long as proper instruments and procedures are used. These same observers agree, however, that more research is needed to understand the subtle dynamics which affect evaluations. Students' expectations (obtained on the first day) and the violation of these expectations are two possible factors. Their effects on students' final interest and future intentions are compared with students' actual reports of the class given at the end of the semester (n=196). Regression analysis using a simultaneous entry of expectations, expectancy violations, and final reports shows that students' reports at the end of the course account for almost all of the explained variance in the course rating items. 相似文献

采用高速摄像法、等速测试和表面肌电等方法,对我国部分男子排球运动员连续助跑能力进行了诊断分析,结果表明:1)在运动员连续15次助跑起跳摸高过程中,重心腾起高度整体上呈现下降的趋势;2)测试的结果验证了功疲劳度指标是一个较好的评价运动员肌肉耐受疲劳能力的功能指标;3)现行20 m内连续5次助跑摸高的测试能否作为反映运动员弹跳耐力水平的指标有待证实。 相似文献

There is limited information on the anthropometry, strength, endurance and flexibility of female rock climbers. The aim of this study was to compare these characteristics in three groups of females: Group 1 comprised 10 elite climbers aged 31.3 +/- 5.0 years (mean +/- s) who had led to a standard of 'hard very severe'; Group 2 consisted of 10 recreational climbers aged 24.1 +/- 4.0 years who had led to a standard of 'severe'; and Group 3 comprised 10 physically active individuals aged 28.5 +/- 5.0 years who had not previously rock-climbed. The tests included finger strength (grip strength, finger strength measured on climbing-specific apparatus), flexibility, bent arm hang and pull-ups. Regression procedures (analysis of covariance) were used to examine the influence of body mass, leg length, height and age. For finger strength, the elite climbers recorded significantly higher values (P < 0.05) than the recreational climbers and non-climbers (four fingers, right hand: elite 321 +/- 18 N, recreational 251 +/- 14 N, non-climbers 256 +/- 15 N; four fingers, left hand: elite 307 +/- 14 N, recreational 248 +/- 12 N, non-climbers 243 +/- 11 N). For grip strength of the right hand, the elite climbers recorded significantly higher values than the recreational climbers only (elite 338 +/- 12 N, recreational 289 +/- 10 N, non-climbers 307 +/- 11 N). The results suggest that elite climbers have greater finger strength than recreational climbers and non-climbers. 相似文献
