学习困难儿童的元记忆监测与控制特点 总被引:13,自引:2,他引:11
以有无意义联系的两种中文词对为材料,采用2×3×2混合实验设计,对小学三到五年级学习困难儿童的元记忆监测、控制水平与学优儿童之间的差异及其发展特点进行研究。结果表明:1.学习困难儿童在三种元记忆监测判断等级上均显著低于学优儿童。2.学习困难儿童具有元记忆控制能力,但其控制水平相对低于学优儿童。3.学习困难儿童的元记忆监测判断和学习时间分配之间存在交互影响。4.学习困难儿童的元记忆监测和控制水平存在较为复杂的发展特点。据此得出结论认为,学习困难儿童的元记忆监测与控制能力都比学优儿童差,同时也表现出一定的发展趋势。 相似文献

An inexpensive, professionally manufactured, digital I/O experiment control interface for any PC-compatible computer is described. It plugs into a standard printer port and provides 1-msec accuracy for up to 4 inputs and 22 outputs. It also allows experiment control procedures to be written in an easy-to-learn, easy-to-use Experiment Control language (ECBASIC). In addition to many instructions specifically designed to simplify behavioral research, ECBASIC provides for transparent collection and storage of event logs. 相似文献

This paper briefly overviews the World-Wide Web. It then provides a short tutorial on the use of the hypertext markup language to publish information on the web. Hypertext markup language is a special page-layout language that was developed to help make creating and retrieving information on the web consistent and efficient. Hyperlinks within hypertext markup language make the language especially powerful because they enable the browser to transparently retrieve images, movies, or audio files from virtually any computer on earth simply by clicking on an item displayed on the monitor. 相似文献

该研究采用"乘法算式答案正误判断的实验室任务",以"奇偶检查策略"为具体策略研究对象,探查内隐奇偶检查策略的存在及其自动性特征。实验结果表明:(1)奇偶检查策略可以以内隐方式存在,但经过不断练习可最终上升到意识层面;(2)奇偶检查策略的外显和内隐使用表现出各自独立的优势效应。外显学习策略的优势效应主要表现在正确算式判断任务中,而内隐学习策略则在错误算式判断任务中表现出"内隐优势效应"的趋势;(3)内隐奇偶检查策略的人为外显化并不能促使个体增加使用该策略的频率,也不能有效提高策略的执行效率。 相似文献

In this article, we introduce a software package that applies a corpus-based algorithm to derive semantic representations
of words. The algorithm relies on analyses of contextual information extracted from a text corpus—specifically, analyses of
word co-occurrences in a large-scale electronic database of text. Here, a target word is represented as the combination of
the average of all words preceding the target and all words following it in a text corpus. The semantic representation of
the target words can be further processed by a self-organizing map (SOM; Kohonen, Self-organizing maps,
2001), an unsupervised neural network model that provides efficient data extraction and representation. Due to its topography-preserving
features, the SOM projects the statistical structure of the context onto a 2-D space, such that words with similar meanings
cluster together, forming groups that correspond to lexically meaningful categories. Such a representation system has its
applications in a variety of contexts, including computational modeling of language acquisition and processing. In this report,
we present specific examples from two languages (English and Chinese) to demonstrate how the method is applied to extract
the semantic representations of words. 相似文献
