New World Writing, a magazine founded by New American Library in 1952, quickly became an important vehicle for liberal intellectual and literary thought. In addition to providing an outlet for new writing, the magazine became an important acquisitions tool for NAL. Throughout its lifetime, New World Writing remained a showcase for many of the finest writers of the 1950s, including Christopher Isherwood, Louis Auchincloss, Tennessee Williams, Flannery O’Connor, Jack Kerouac, and Gore Vidal. He is the author of Under Cover: An Illustrated History of American Mass Market Paperbacksand Heavy Traffic and High Culture: The New American Library as Literary Gatekeeper.

Recent implementation of Nebraska's Standards-based Teacher-led Assessment and Reporting System (STARS) introduced a unique opportunity to examine the benefits and drawbacks of a teacher-led state assessment system. STARS is unique among state assessment systems in that statewide tests are replaced by locally developed assessments designed by teachers. Benefits of this system are found to be greater teacher use of results for instructional planning, greater diagnostic utility of the assessments, and gains in assessment literacy. Disadvantages include the time-consuming and stressful nature of creating localized assessments. Compatibility of STARS with the requirements of the No Child Left Behind Act are discussed.  相似文献

The aim was to examine cross-cultural variation in linguistic responsiveness to young children in 10 English-speaking mother–child dyads and 10 Italian-speaking mother– child dyads. All 20 children were late talkers who possessed delays in expressive vocabulary development but age-appropriate cognitive and receptive language skills. Dyads were filmed in 15 minute free play contexts, which were transcribed and coded for measures of maternal linguistic input (e.g. rate, MLU, labels, expansions) and child language productivity (e.g. utterances, different words used). The results revealed that the Italian mothers used more utterances, spoke more quickly and used a more diverse vocabulary than the Canadian mothers. The Italian children mirrored their mothers and also used more utterances and a more diverse vocabulary than the Canadian children. Mothers in both groups used similar percentages of responsive labels and expansions. However, Italian mothers responded to fewer of their children's vocalisations, using a smaller percentage of imitations and interpretations than the Canadian mothers. Correlations between maternal input and children's language productivity revealed that contingent language measures (e.g. imitations, interpretations, expansions) were related to high levels of productivity in children in both cultural groups. The results support the use of language interventions based on increasing maternal responsiveness for these children at the one-word stage of language development. They also point to differences that may be culturally based. For example, Italian mothers use faster rates of interaction and appear to have higher expectations for their children's verbal participation in interaction. This is reflected in higher rates of language production from their children, even though children in both cultural groups have similar vocabulary sizes.  相似文献
