Effects of pairs of problems and examples on task performance and different types of cognitive load

In two studies, we investigated whether a recently developed psychometric instrument can differentiate intrinsic, extraneous, and germane cognitive load. Study I revealed a similar three-factor solution for language learning (n = 108) and a statistics lecture (n = 174), and statistics exam scores correlated negatively with the factors assumed to represent intrinsic and extraneous cognitive load during the lecture. In Study II, university freshmen who studied applications of Bayes' theorem in example–example (n = 18) or example–problem (n = 18) condition demonstrated better posttest performance than their peers who studied the applications in problem–example (n = 18) or problem–problem (n = 20) condition, and a slightly modified version of the aforementioned psychometric instrument could help researchers to differentiate intrinsic and extraneous cognitive load. The findings provide support for a recent reconceptualization of germane cognitive load as referring to the actual working memory resources devoted to dealing with intrinsic cognitive load.     

Using LSA and text segmentation to improve automatic Chinese dialogue text summarization

Automatic Chinese text summarization for dialogue style is a relatively new research area. In this paper, Latent Semantic Analysis （LSA） is first used to extract semantic knowledge from a given document, all question paragraphs are identified, an automatic text segmentation approach analogous to Text＇filing is exploited to improve the precision of correlating question paragraphs and answer paragraphs, and finally some ＂important＂ sentences are extracted from the generic content and the question-answer pairs to generate a complete summary. Experimental results showed that our approach is highly efficient and improves significantly the coherence of the summary while not compromising informativeness.

蒙古语的bilig、blg、keseg与突厥语的bil-、bl-、kes-——兼谈词根分析法

对比分析蒙古语的 bilig、bo¨ lo¨ g、keseg和突厥语的 bil-、b l-、kes-以及相关的其他一些词 ,补充了一些语言材料 ,提出对于黏着语言而言 ,词根分析法是有效的 ,但它并不是万能的。如果没有充分掌握所比较研究的相关语言的可靠而丰富的材料 ,就使用词根分析法 ,其结论常常事与愿违 ,往往是不可靠的。所以在使用词根分析法时应充分掌握相关语言的可靠且丰富的语言材料作为先决条件才是     

Automatic extraction of bilingual word pairs using inductive chain learning in various languages

In this paper, we propose a new learning method for extracting bilingual word pairs from parallel corpora in various languages. In cross-language information retrieval, the system must deal with various languages. Therefore, automatic extraction of bilingual word pairs from parallel corpora with various languages is important. However, previous works based on statistical methods are insufficient because of the sparse data problem. Our learning method automatically acquires rules, which are effective to solve the sparse data problem, only from parallel corpora without any prior preparation of a bilingual resource (e.g., a bilingual dictionary, a machine translation system). We call this learning method Inductive Chain Learning (ICL). Moreover, the system using ICL can extract bilingual word pairs even from bilingual sentence pairs for which the grammatical structures of the source language differ from the grammatical structures of the target language because the acquired rules have the information to cope with the different word orders of source language and target language in local parts of bilingual sentence pairs. Evaluation experiments demonstrated that the recalls of systems based on several statistical approaches were improved through the use of ICL.

新教师“师徒结对”培养模式的缺憾与对策

当下新教师"师徒结对"培养模式存在缺憾,如:行政安排的"单向选择"结对方式,单向传授的经验模式,缺乏激励的考核机制。为充分发挥"师徒结对"培养模式应有的作用,可采取如下对策:自主选择结对方式、打破一徒一师的师徒关系、建立平等的师徒关系、构建激励相容的评价机制。     

屏蔽二进序列偶的构造

对屏蔽二进序列偶进行研究,证明了一类特殊的差集偶与最佳屏蔽二进序列偶是等价的,以及另一类特殊的差集偶与伪随机屏蔽二进序列偶是等价的;证明了几乎最佳屏蔽二进序列偶与一类特殊的可分差集偶之间的等价关系,为应用差集偶和可分差集偶构造屏蔽二进序列偶提供了理论依据。利用分圆类方法构造与最佳屏蔽二进序列偶等价的差集偶,得到几类最佳屏蔽二进序列偶。     

杜亚泉编辑自然科教科书的思想与实践

杜亚泉是民国时期著名的自然科教科书编辑者。讲求实学、救世济民的理想和对自然科教科书作用的认识,是他编辑自然科教科书的动因。他提出了选择教材的＂四要件＂思想和应处理好的三对关系,并贯彻和体现在其所编辑的自然科教科书内容中。他编辑教科书的思想与实践发挥了重要的启民智、育新人的历史作用,是一份珍贵的文化遗产,对我们今天仍有借鉴意义。
