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

A small nation in the middle of the North Atlantic, Iceland currently has a population of 265,000 (1996). The Iceland language has changed very little since the island was settled some 11 centuries ago. Despite the relatively small number of people who speak the language and irrespective of the globalisation efforts by the international community, which includes the ever-increasing influence of English worldwide, the Icelandic language and culture are stronger than ever. The current volume and variety of publications of Icelandic works in all areas have never been as great. Icelandic is a living and growing language. Growth in vocabulary, in response to recent phenomena like the introduction of new technology, has primarily come about with the development of new words from the language's roots. The near absence of Latin, Greek and, more recently, English or Danish words in Icelandic, is striking. Iceland's language policy is not only a governmental policy. It is a policy that comes from the grassroots with the government and official institutions viewing their job as one of service to the people of Iceland. Icelanders are very proud of their language and are extremely determined to continually develop and preserve it for future generations.  相似文献

Females and youth are frequently described as "special" populations in football literature, but together these two populations outnumber male players. What makes females "special" is that they tend to eat less when training and competing than their male counterparts, leading to lower intakes of energy, carbohydrate, and some nutrients. Youth football players are special in regard to energy and nutrient requirements to promote growth and development, as well as to fuel sport. There is limited research on the dietary habits of these two populations, but the available literature suggests that many female and youth players need to increase carbohydrate intake, increase fluid intake, and develop dietary habits to sustain the demands of training and competition.  相似文献
