基于网络的大学英语“体验翻译”教学问题与反思

我校于2011年3月至2012年1月在2010级A级的4个班上开展了基于网络的大学英语"体验翻译"教学实验。本文旨在总结本次教学实验中所发现的问题,并对现阶段的大学英语翻译教学进行了反思。     

Externalizing behavior problems and interest in reading as predictors of later reading skills and educational aspirations

This study examined the developments in children’s externalizing problems and interest in reading during their first four years of school (Grades 1–4) and investigated whether this development predicted the children’s Grade 6 reading skills and educational aspirations. Data comprised (1) teachers’ ratings of externalizing problems and children’s (N = 642; 43% girls) self-ratings of their interest in reading, collected between Grades 1 and 4, and (2) measures of reading fluency and comprehension, and children’s self-reports of educational aspirations, collected at Grade 6. First, latent growth modeling showed that a higher level of externalizing problems in Grade 1 was associated with a lower concurrent interest in reading. Second, a positive association between the initial level of interest in reading and a linear change in externalizing problems indicated that children with a lower interest in reading in Grade 1 were rated by teachers as exhibiting higher levels of externalizing problems, which nonetheless declined over the course of their first four years of school more than among other children. Third, a higher initial level of externalizing problems with a linear change in these problems across Grades 1–4 was a predictor of lower subsequent educational aspirations and poorer reading comprehension in Grade 6. Analysis of the indirect effects indicated that a higher level of externalizing problems was associated with a lower concurrent interest in reading, which, in turn, was related to poorer future reading fluency and lower educational aspirations. The findings imply that problem behaviors are interlinked with academic skill development and motivation across the first six years of school.

初中生心理健康的调查和策略研究

虽然国家一再强调基础教育的一项重要任务是让学生身心健康成长,但是学生厌学、逃学,甚至轻生的现象越来越多。学生究竟存在哪些心理问题？学生心理问题出现的原因是什么？作为基础教育主要场所的学校,该从何着手解决这一问题？所以课题组以心理健康调查为起点,通过探究学生存在的心理问题,探索出适合我校心理健康教育的模式,旨在让每一位学生都能身心健康地快乐成长！     

儿童早期音高发展的研究

在声调语言环境下成长的婴儿的前语言阶段的音高发展呈现什么样的规律,为儿童语言习得领域中一重要研究课题,但迄今相关研究甚少。基频负载着声调的主要区别特征。实现基频的直接物质是声门。而此阶段的婴儿声门处于不稳定的状态。本文指出婴儿前语言阶段音高的发展规律的研究应该采用对数 z-score(LZ)的方法,与此相应的频域定义取平均值和标准偏差,对婴儿的前语言阶段(八个月到一岁三个月或更早)的音高进行归一化。并采用软件 Praat 进行语音分析。指出了婴儿前语言阶段的音高规律研究的意义和研究方法。     

对"问题孩子"的思考

“问题孩子”常常让家长和老师感到头疼和棘手,了解他们的特点,看到他们的优点。关爱、引导他们朝正确的方向发展是至关重要的。
