Digital documents in the networked information environment fundamentally change the ways that visual materials can be used in education and scholarly discourse. These new uses raise questions about research library strategies with regard to digitized visual materials as a part of their collections, challenge assumptions underlying intellectual property rights for images and their scope, and offer ways in which visual literacy can become a more integral part of the common educational experience.  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

The poor reading achievement of African-American children in urban schools is well established. African-American children from low-income homes may be at particular risk for reading difficulties, although middle-income children often fare poorly as well. Intervention efforts have focused on children in kindergarten through fifth grade. This article suggests that prevention efforts must begin prior to kindergarten entry. Several key variables that may influence young children's performance, including poverty, general oral language skills, dialectal variations, home literacy practices, standardized testing bias, and teacher expectations, are explored. Future directions for research addressing emergent literacy in African-American children are discussed throughout.  相似文献
