中学生学习动机与学习自我管理策略的相关研究

采用自编问卷对845名中学生进行调查研究。结果表明：不同类别和不同性别的中学生在学习动机和学习自我管理策略的各个维度上,呈现出不同的差异;中学生学习动机7个维度与中学生自我管理策略的五个维度之间有显著的相关。多元回归分析后发现：中学生学习动机与中学生学习自我管理策略关系密切且呈较强的相关,成就动机、任务动机、期望动机与学习自我管理策略的回归效应尤为明显。并针对发现的问题提出了教育建议。     

从英语发展史看英语中的外来词

语言是反映社会生活的一面镜子,而作为语言最敏感、最活跃因素的词汇,则是观察社会生活变化的一个窗口。随着我国对外交往的日益频繁,来自英语的外来词(借词)日益增多,特别是在中国进行改革开放的新时期,中外文化的多层次、多渠道的交流为词语的借用提供了多种条件。正如美国著名的语言学家萨丕尔所言:"一种语言对另一种语言最简单的影响是词的‘借贷’。只要有文化借贷,就可能把有关的词也借过来。"因此,我们可以从借词中窥见文化交流的方方面面,并通过词语借用方式来发掘沉积在一个民族心理结构中的深层内蕴。本论文分析了英语这门语言的发展史,包括外来词以何种方式引入到英语中,以及英语外来词的影响力和分类。

A comparison of difficulty and discrimination values of selected true-false item types

Thirty-eight undergraduate students were randomly assigned one of two alternate forms of a 144-item true-false midterm examination. Whenever a statement appeared on one form as true and positively stated, it appeared on the alternate form as false and negatively stated. Similarly, a false and positively stated item on one form was true and negatively stated on the other. The subject matter of the two forms was identical and the four kinds of true-false items were equally represented on each form. Difficulty and discrimination indices were computed for each of the four item types. The statistical results showed negatively stated items were more difficult, but no more discriminating, than positively stated items. Also, false items were not statistically more difficult than true items, but were significantly more discriminating. It was concluded that test constructors should include more false items than true items in their instruments and that all items should be stated positively.

在中国"入世"背景下看中西文化趋同与差异

近年来,中国与西方国家在文化、贸易等领域的交往日益增多.在此过程中,中西方各自不同的价值观念、民族心理、语言习惯、民俗风情、生活方式等相互渗透、融合,同时又不可避免地发生碰撞与冲突,从而出现了中西文化诸多的趋同与差异现象,本文在中国"入世"背景下对这些现象进行了深入的分析.     

Spontaneous focusing on quantitative relations as a predictor of rational number and algebra knowledge

Spontaneous Focusing On quantitative Relations (SFOR) has been found to predict the development of rational number conceptual knowledge in primary students. Additionally, rational number knowledge has been shown to be related to later algebra knowledge. However, it is not yet clear: (a) the relative consistency of SFOR across multiple measurement points, (b) how SFOR tendency and rational number knowledge are inter-related across multiple time points, and (c) if SFOR tendency also predicts algebra knowledge. A sample of 140 third to fifth graders were followed over a four-year period and completed measures of SFOR tendency, rational number conceptual knowledge, and algebra knowledge. Results revealed that the SFOR was relatively consistent over a one-year period, suggesting that SFOR is not entirely context-dependent, but a more generalizable tendency. SFOR tendency was in a reciprocal relation with rational number conceptual knowledge, each being uniquely predictive of the other over a four-year period. Finally, SFOR tendency predicted algebra knowledge three-years later, even after taking into account non-verbal intelligence and rational number knowledge. The results of the present study provide further evidence that individual differences in SFOR tendency may have an important role in the development of mathematical knowledge, including rational numbers and algebra.
