Evidence shows that initial and advanced learning to read are predominantly mediated by the right and left cerebral hemispheres, respectively. Premature reliance on left-hemispheric reading strategies may result in L-type dyslexia, characterized by hurried and inaccurate reading. P-type dyslexia, characterized by a slow and fragmented style of reading, may result from the inability to shift from the predominant generation of right-hemispheric reading strategies to the predominant generation of left-hemispheric reading strategies. Results of investigations concerning the validity of the L/P-typology are discussed, as are the reading effects of hemisphere-specific and hemisphere-alluding stimulation in children with L- and P-type dyslexia.  相似文献

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

辽宁省部分普通高校女大学生体育现状的调查研究   总被引:1,自引:0,他引:1  
运用问卷调查、数理统计、文献资料、专家访谈等方法、对辽宁部分普通高校女大学生体育现状进行调研分析,结果表明:体育需求表现出多元化的特点;关注体育的态度以及对余暇体育活动主动性不高,女大学生对体育课的满意程度呈正态分布,活动场地以校内的运动场(馆)为主:大部分学生每周不同程度地参加体育活动但活动时间比较短,锻炼效果不高。  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

对苏州老城区居民健身活动场所开发利用的研究   总被引:1,自引:0,他引:1  
采用问卷调查、实地考察和访谈等方法,对苏州老城区居民健身活动场所进行研究。结果显示,苏州老城区社区体育环境设施已成为影响居民健身锻炼的主要原因之一,与广大居民日益增长的健身需求极不相称。针对苏州老城区的特点提出,充分利用学校体育设施资源;结合古城区改造,规划好居民体育活动场所;加强社区体育组织管理;引导居民健身锻炼消费;经营性体育场所转变思路,将服务重点转向中老年群体等建议。  相似文献
