决定战争胜负的“人”

人不同于物的特点在于人既是思想者又是行动者,人作为战争的物质力量之时渗透着情感、意志、智慧之光。参加反法西斯斗争的各国人民表现的高度的历史能动性加速了法西斯势力的灭亡,推动了人类历史发展的进程。“落后就要挨打”,只有依靠全国亿万人民振奋精神,努力奋斗才能改变落后面貌,在一定意义上可以说比落后更为可怕的是人缺少上进拼搏的精神。

Time Collocation Method for Structural Dynamic Problems

In order to achieve highly accurate and efficient numerical calculations of structural dynamics, time collocation method is presented. For a given time interval, the numerical solution of the method is approximated by a polynomial. The polynomial coefficients are evaluated by solving alge-braic equation. Once the polynomial coefficients are evaluated, the numerical solutions at any time in the interval can be easily calculated. New formulae are derived for the polynomial coefficients, which are more practical and succinct than those previously given. Two structural dynamic equations are calculated by the proposed method. The numerical solutions are compared with the traditional fourth-order Runge-Kutta method. The results show that the method proposed is highly accurate and computationally efficient. In addition, an important advantage of the method is the simplicity in software programming.     

师生关系的社会学探讨

对于师生关系历来有不同的认识,有的是静态的、理想的,有的是动态的、现实的。社会学对师生关系的探讨着重于从师生在教育活动中的相互作用入手,把师生关系放置在现实的社会背景中去认识和思考,对教育学研究有一定的启示意义。     

Stable response of axisymmetric two-phase water-saturated soil

Biot's dynamic consolidation equations and Hankel transform were used to derive the integral solutions of stress and displacement for axisymmetric harmonic excitations in the two-phase saturated soil with subjacent rock-stratum. The influence of the coefficient of permeability and loading frequency on the soil displacement at the ground surface were studied. The results showed that higher loading frequency led to more dynamic characteristics; and that the effect of the soil permeability was more obvious at higher frequencies.     

The design and development of the dragoon intelligent tutoring system for model construction: lessons learned

This paper describes Dragoon, a simple intelligent tutoring system which teaches the construction of models of dynamic systems. Modelling is one of seven practices dictated in two new sets of educational standards in the U.S.A., and Dragoon is one of the first systems for teaching model construction for dynamic systems. Dragoon can be classified as a step-based tutoring system that uses example-tracing, an explicit pedagogical policy and an open learner model. Dragoon can also be used for computer-supported collaborative learning, and provides tools for classroom orchestration. This paper describes the features, user interfaces, and architecture of Dragoon; compares and contrasts Dragoon with other intelligent tutoring systems; and presents a brief overview of formative and summative evaluations of Dragoon in both high school and college classes. Of four summative evaluations, three found that students who used Dragoon learned more about the target system than students who did equivalent work without Dragoon.     

第三部门视野中的教育产权分析

教育产权问题是教育经济领域争论比较激烈的问题之一，原因是许多研究者认为它是制约我国教育特别是民办教育发展的根源之一。虽然理论工作者从多维视角进行了许多有益的探索，但从实际情况来看并未对现实情况产生较大影响。试图从另一个全新的视角进行探讨，并希冀从中得到启示，其结论是第三部门视野中的教育不存在产权问题，现实情况也说明并没有因为产权问题而影响我国教育的发展。
