关于汉语语感教学的思考

语言教学的目的是培养学习者的语言能力,而语言能力的核心是语感能力。本文通过对少数民族学生学习汉语时对偏误的判断和纠错缘由的测试,以及笔者的教学实践,说明培养学生汉语语感应成为汉语教学的目标,并提出相应的教学建议。     

Examining Intermediate Omitted Levels in Hierarchical Designs via Latent Variable Modeling

This article outlines an interval estimation procedure that can be used in a 3-level setting to evaluate the proportion of outcome variance attributable to the second level of clustering. The method is useful for examining the necessity of including a possibly omitted intermediate level of nesting in analyses of data from a multilevel study, and represents an informative addendum to current statistical tests of second-level variance. The approach is developed within the framework of latent variable modeling and can be used as an aid in the process of choosing between 2-level and 3-level models in a hierarchical design. The discussed procedure is illustrated with an empirical example.

对戏曲发声和美声唱法的探讨

戏曲发声与美声唱法在很多方面是相通的。基于戏曲发声的特性,将其与美声唱法进行比较研究,分析科学发声的原理及与京剧发声的关系,了解掌握气息的原理与运用,正确稳定喉头的位置,体腔调节与运用等。在训练戏曲演员时可以借鉴美声训练方法,对旦角学生剧目中的唱段进行发声指导,针对僵化模仿、呼吸偏误、无准备发声、真假声不能自如运用等七种弊病进行指导练习,以期在保护戏曲发声特点本体的同时,将科学发声方法为我所用,促进戏曲艺术的进步与发展。     

Different Policies to Different Errors

Making of errors is an inevitable and indeed necessary part of the learning process.We should have positive attitude towards errors and the policies towards error correction should be flexible and adaptable.Teachers should have different policies towards different errors.For example,pre-systematic error should be tolerated.The immediate correction is ineffective.The systematic error should be corrected immediately,with the help of the teacher.And the teacher should encourage the student to discover and correct the post-systematic error by themselves.

Discriminating Quantity: New Points for Teaching Children with Down Syndrome About Number?

ABSTRACT

The focus of much mathematics teaching has been on the acquisition of counting, an area where children with Down syndrome can experience particular difficulties. Research with typically developing children has highlighted how early awareness of quantity provides a strong platform for the acquisition of later mathematical skills and programmes of early intervention have been introduced. Many of these studies are embedded in the work and traditions of developmental and cognitive psychology and can be difficult to access. Consequently, this is an area that has been largely ignored in the curricula of children with Down syndrome. This paper seeks to make this literature more available. It systematically reviews previous research with children with Down Syndrome on these early foundations. It considers seemingly contradictory findings in the light of differences in tasks, their presentation and instructions, and the responses required, in order to draw conclusions and reflect on the implications for teaching and learning. Some of these propositions are in contrast to existing practices and call for further research to test their effectiveness.
