The effect of language specific factors on early written composition: the role of spelling,oral language and text generation skills in a shallow orthography     

Barbara Arfé  Julie E. Dockrell  Bianca De Bernardi 《Reading and writing》2016,29(3):501-527

Spelling skills have been identified as one of the major barriers to written text production in young English writers. By contrast oral language skills and text generation have been found to be less influential in the texts produced by beginning writers. To date, our understanding of the role of spelling skills in transparent orthographies is limited. The current study addressed this gap by examining the contribution of spelling, oral language and text generation skills in written text production in Italian beginner writers. Eighty-three children aged 7–8 years participated in the study. Spelling, lexical retrieval, receptive grammar, and written sentence generation and reformulation skills were assessed and children were asked to write a text on a set topic. A factor analysis revealed that the children’s written text production was captured by three factors: productivity, complexity and accuracy. In contrast to results from children learning to write in opaque orthographies, such as English, this study showed that receptive grammar and written sentence generation skills accounted for significant variance in measures of productivity, complexity and accuracy in Italian children’s written text production. Spelling skills contributed to text accuracy and quality and explained more variance than receptive grammar in microstructural accuracy. By contrast, oral grammatical skills explained more variance in text quality than spelling. The current study shows the differential impact of language systems, such as Italian, on written text production. Implications for assessment and instruction are outlined.  相似文献   

声音在空气中的传播     

刘水莲 《物理教学探讨》2007,25(2):49-49

原人教版初中物理教材“声音在空气中的传播”一节，安排了这样的演示实验：用两个相同的音又，左边音叉旁挂一个塑料小球，敲击右边的音叉，发现塑料小球弹开。说明右边音叉的振动通过空气传给了左边的音叉。这个实验能说明声音可以在空气中传播，但事实上这个实验很难成功，因为它对音叉的频率要求很严格。现行教材将此实验删除，却没有新实验来替代。笔结合自身教学实践，设计了一个替代实验，供大家参考![第一段]  相似文献

镓(Ⅲ)—溴邻苯三酚红—邻菲啰啉三元配合物的研究     

吴心传  刘艺 《湖南师范大学教育科学学报》1994,(5)

本文拟定了一种微量镓(Ⅲ)的测定方法:当有聚乙烯醇存在时,在PH3.6的醋酸—醋酸钠缓冲溶液中,镓(Ⅲ)能与溴邻苯三酚红及邻菲啰啉形成兰紫色三元配合物,λ_(max)=615nm,镓(Ⅲ)的量在0.095～35μg/25ml范围内符合比尔定律。其表观摩尔吸光系数ε_(615)=3.69×10~4,此法用于铝合金中微量镓(Ⅲ)的测定,相对偏差小于3％,结果准确度高。  相似文献
