基于DSP的心电信号采集存储系统设计

介绍了一种以TI公司的TMS320LF2407A DSP芯片为核心的实时数据采集存储系统设计方案.该系统通过外接12位AD转换器AD7858来提高DSP采样精度,实时采集病人的心电数据,通过数字滤波处理后可以真实反映病人的心脏健康状况,借助串口电路建立与上位机的通讯.相对于采用PC机和单片机设计的系统,该系统具有功耗小、成本低、实时性强等优点.     

完形默读法：汉语第二语阅读理解监控试验教学研究

文章以＂为意义而阅读＂为基本的阅读理念,把测量阅读理解和教材难易度的阅读填空（Cloze）测量法应用在第二语课堂阅读教学中,设计成＂完形默读法＂（Cloze Silent Reading Method）,作为阅读过程中的自我监控工具,让学习者能集中注意、调动先备知识与经验,主动与语篇交际。研究结果初步发现,初中二年级的受试在经过第一阶段完形默读历程后,其字面性理解力提升,推论理解力也有所提升;从教学意义来看,完形默读法能发挥理解监控的正面作用,促进学习者的阅读力,意味着第二语阅读过程之教学的一种突破。

Introduction to the special issue on genes, environment, and reading

This introduction to the special issue on Genes, Environment, and Reading presents an overview of the background for behavior- and molecular-genetic research on dyslexia and individual differences across the normal range. The general methods, questions addressed, and selected results are summarized for each of the papers in the order of their presentation in the special issue. Concluding comments reflect on the influence of environmental range on estimates of genetic and environmental influences, and the future of behavior- and molecular-genetic research on reading.     

过程性知识的特征及习得——基于数学解题的视角

过程性知识是基于学习者亲身体验的个体知识。在数学解题中,过程性知识制约着解题过程和结果。过程性知识的本质特性决定了其习得过程不同于陈述性知识或程序性知识。     

The cooking teacher: investigating gender stereotypes in a Korean kindergarten

This article discusses some findings from a small‐scale investigation of children's gendered beliefs and behaviours in a Korean kindergarten which was attempting to challenge gender stereotyping through the anti‐bias intervention of a ‘cooking curriculum’. A sample of 14 children, some with ‘working’ mothers and some with ‘housewife’ mothers, was observed for two months, and informally interviewed on several occasions. The children's mothers were also interviewed. The findings are situated in the context of the changing, but still traditional, culture of Korean society, as well as in the contexts of early childhood education and theories of gender acquisition. They confirm that, although children are highly likely to reproduce the beliefs current in their home environment, they are open to reconstructing these views when actively challenged to consider alternatives, either by the school curriculum or by engaging in debate with a researcher or practitioner. The nature of the ‘alternative’ views available may however be problematic.
