Examining Samoan language development in Samoan bilingual students＇ understanding of texts in English

This paper examines language development of Samoan students in bilingual contexts in Aotearoa, New Zealand. In the absence of valid and standardized assessments tools in Samoan, one was designed to test reading comprehension and oral language development for Samoan students using common narratives as a base. For reading comprehension, the tool used a listening comprehension format to avoid possible decoding limitations and provided a gradient of difficulty with a surprising drop in both oral and reading comprehension at year 7. This drop was attributed to a change in competencies of some students entering the bilingual classroom at year 7. For example, the mixed levels of both L 1 （Samoan） oral and L1 （Samoan） reading comprehension within and across years of schooling likely reflects the varied provision in the Samoan bilingual classes and the variations across cohorts in different degrees of bilingualism. We argue that this might be due to the make up of the two schools of which one was an Intermediate school of years 7 and 8 students and, the other was a full primary school with students from years 4 to 8. The patterns suggest two general instructional needs in Samoan bilingual classrooms. One is the need to develop metacognitive components and the need for deliberate and explicit instruction to build awareness of strategies and effectiveness. The other is the ubiquitous need identified in reading comprehension instruction generally to develop vocabulary both through oral and written forms. There was a highly significant relationship between L 1 oral at L1 reading comprehension levels reflecting a general relationship found in other studies of monolingual in L2 （English） contexts.     

R&D与信息化投资对IT企业效率和生产率的影响研究

运用非参数的数据包络分析模型从实证的角度计算了中国电子信息百强企业中的9家IT企业的相对效率、技术进步和全要素生产率(以Malmquist指数衡量),分析了R&D与信息化投资对这些指标的影响,得出的结论是:①长白计算机集团公司和七喜控股股份有限公司2003—2006年都能达到效率最优;②R&D与信息化投资对IT企业的技术进步和全要素生产率的影响不容乐观。然后总结了一些提高效率、促进技术进步的建议。     

竹炭负载二氧化钛吸附甲醛的研究

采用溶胶-凝胶法制备TiO2溶胶,采用浸渍-过滤法将TiO2负载于载体颗粒竹炭(BC)的表面,制成竹炭负载二氧化钛的复合物TiO2/BC,并对甲醛进行吸附实验。结果表明:BC和TiO2/BC对甲醛都具有较强的吸附,但是达到饱和吸附时,TiO2/BC的吸附量较大,单位时间内TiO2/BC的吸附甲醛的质量比BC多,且经过多次负载的TiO2/BC其对甲醛的吸附量增加,以负载3次为佳。     

普通高校武术课程课内外一体化改革的实验研究

传统的单一课堂教学模式已不适应高校体育课程发展的需要，它严重制约了各项体育运动的健康发展，武术运动也不例外。实验证明．实施课内外一体化的武术课程满足了大学生的求知欲，教学效果良好，有效地推动了武术运动的健康发展、课程模式符合当前高校体育课程改革的要求，并广泛实用于其它体育课程。

Struggling to balance various stakeholders’ perceptions: the work life of ideo-political education teachers in China

As a compulsory course at universities throughout the Chinese Mainland, ideo-political education aims to safeguard university students’ political loyalty to the Communist Party. By employing a qualitative research method, this study investigated a renowned comprehensive university in southern China. The case study found that students expressed strong resistance to compulsory ideo-political courses. From the outset, teachers had to work to change students’ overwhelmingly negative perceptions of ideo-political education. Informants found that they could not attract student interest if they only strictly followed the state designed textbook, and therefore chose instead to cover topics they found more interesting and to discuss social issues in their lectures. However, the new curriculum reform and teaching quality assurance mechanism placed further restrictions on teaching and learning. Whether teachers could maintain enough autonomy to make the above adjustments depended on the understanding and support of key senior academics.
