“预测”用英语表达即为“predict”或“anticipate”，是指对时间上比现在更远的未来进行推测。这里所谈的预测是指教师在英语听力教学中，正确地引导学生在听材料之前，根据材料所给的有限信息如标题和要求完成的练习等等，充分调动他们自己原有的相关的知识和经验，对将要听的材料的内容进行猜测和推理，在大脑中形成他们自己的关于材料内容的构想，然后，在听的过程中证实他们的猜测是否与材料的实际内容一致。预测法即正确地引导学生讲行预测的方法． 相似文献

预测心智主张大脑是一台预测机器,用有层级的感觉推理和主动推理来减少预测误差。这一理论强调认知的实践优先性,掀起了认知科学和心灵哲学内部的“哥白尼式的革命”。预测心智的认知观与杜威的认识论有共通之处。杜威将实验探究视为认识的本质,蕴含了知行合一、行动优先之旨。杜威的实验探究认识论在三个方面与预测心智相契合。首先,探究是一种预测误差最小化,其形式是主动推理。其次,具有操作本性的观念对应于数字化概率的假设。最后,在康德的意义上,由探究后果建构的认识对象对应于先验概率。由这三个相似点出发,能更好理解二者对知行优先性的处理：二者都将知识和行动看作实现善果的手段。阐明预测心智和杜威认识论的联系,有助于发掘古典实用主义思想在当代心灵哲学中的价值,推进知行哲学的研究。 相似文献

在大学英语学习中,听力是非常重要的一个方面,也是最难掌握的一项内容。造成学生听力学习比较困难的原因很多,比如缺乏语音知识、掌握的词汇量较少等,其中非常主要的一个原因是缺乏听力学习策略。要想提高大学英语听力水平,必须发展预测和推理能力。本文简要分析了在大学英语听力学习中发展预测和推理能力的策略,希望可以提供一些有价值的参考意见。 相似文献

从建立稳定、精确的非线性预测模型出发,以Broyden,Fletcher,Goldfarb和Sharmo(BFGS)的拟牛顿优化算法为基础,在神经网络的训练过程中引入两个含有不同参数的拟牛顿校正公式并行的确定搜索方向,通过不精确搜索法求取最优步长,最后根据性能指标取最优的一个搜索方向和相应的步长对网络各层之间的权值进行修正。控制器采用神经网络递推多步预测、自补偿式在线闭环反馈校正以及迭代学习求解进行优化的方法。Matlab仿真结果验证了该方法的有效性。 相似文献

Although there have been numerous studies investigating the predictive validity of early assessment, observed predictive validity coefficients across studies are not stable. A validity generalization study was conducted in order to answer the question of whether the relationship between early assessment of children and later achievement is generalizable or situation-specific. This study examined 716 predictive correlation coefficients from 44 studies using Hierarchical Linear Modeling (HLM). The findings of this study revealed that predictive validity of early assessment is not generalizable. Additional analyses indicated that predictive validity differ across assessments as a function of test type, specific construct being assessed, length of prediction, and administration procedures. The most impressive finding in this study was the variability of effect sizes across different test administration types. In particular, tests that were scored through ratings were found to be most effective. These findings suggest that instead of addressing a broad predictive validity between a test and a criterion measure, it is necessary to understand early assessment procedures as a whole system by including considerations of various variables related to testing conditions. 相似文献

This article reviews ten predictive validity studies of the Swedish Scholastic Assessment Test (SweSAT). A primary result is that the predictive validity of the SweSAT seems to be highly dependent upon the study programme being examined; that is, the predictive validity is better at some programmes than others. When compared with the upper‐secondary school grade point average, the predictive validity of the SweSAT seems to be fairly good, but there are major differences between study programmes in this case as well. However, it is suggested that the validity of the results is to some extent threatened by methodological issues. A general conclusion is, therefore, that there is room for improving the test itself, as well as the way that predictive validity studies are carried out. 相似文献

A nonlinear model predictive control problem based on pseudo-linear neural network (PNN) is discussed, in which the second order on-line optimization method is adopted. The recursive computation of Jacobian matrix is investigated. The stability of the closed loop model predictive control system is analyzed based on Lyapunov theory to obtain the sufficient condition for the asymptotical stability of the neural predictive control system. A simulation was carried out for an exothermic first-order reaction in a continuous stirred tank reactor. It is demonstrated that the proposed control strategy is applicable to some of nonlinear systems. 相似文献

Education can be seen as a social structure that reproduces existing levels of social, economic, and cultural distributions. Using Vietnam as a case study, this paper seeks to examine how these theories hold up in a socio-political and socio-economic context that has been less examined, specifically in one of the few remaining single-party socialist countries that advocates Communism. The findings suggest prior levels of social stratification are predictive of educational attainment, and educational attainment is predictive of employment. Higher educational attainment is also predictive of having occupations in economic sectors with less repetitive work and more autonomy. 相似文献

This article describes a predictive model that assesses whether a student will have greater perceived learning in group assignments or in individual work. The model produces correct classifications 87.5% of the time. The research is notable in that it is the first in the education literature to adopt a predictive modeling methodology using data collected via a designed experiment. All subjects experienced both a collaborative and an individual assignment, thus mitigating uncontrolled external factors in the measurement of differences in perceived learning. The exploratory nature of the work prompted the use of Partial Least Squares Regression for estimation. The work serves as an illustration of how predictive modeling might enlighten those in educational and academic settings. 相似文献
