关于CAI的思考

 随着计算机的不断普及,计算机辅助教学在教育教学过程中已得到了广泛的应用,这无疑是教育史上的一次新的革命,但在计算机辅助教学过程及CAI软件开发中也暴露出了一些新的值得注意的问题,本文中试将这些问题作一些分析,以供借鉴。在CAI教学过程,下列不良倾向值得注意:彻底否定传统教学形式认为传统的教学方法都是失败的、落后的,都不如计算机辅助教学;而计算机辅助教学则是无所不能,无论什么教学内容、任何课型,只要应用了计算机辅助教学,教学中的任何问题都可迎刃而解,甚至认为一节课不应用计算机辅助教学,就不是一节好课。

CMS Grid Activities in Europe

The CMS experiment at the CERN LHC collider is producing large amounts of simulated data in order to provide an adequate statistic for the Trigger System design.These productions are performed in a distributed environment,prototyping the hierarchical model of LHC computing centers developed by MONARC.A GRID approach is being used for interconnecting the Regional Centers.The main issues which are currently addressed are:automatic submission of data production requests to available productioin sites,data transfer among production sites,“best-replica” location and submission of enduser analysis job to the appropriate Regional Center,In each production site different hardware configurations are being tested and exploited.Furthermore robust job submission systems.which are also able to provide the needed bookkeeping of the produced data are being developed.BOSS(Batch Object Submission System)is an interface to the local computing center scheduling system that has been developed in order to allow recording in a relational database of information produced by the jobe running on the batch facilities A summary of the current activites and a plan for the use of DataGrid PM9 tools are presented.

开发面向分析化学的复杂方程绘图求解软件

化学平衡的精确解析会涉及复杂方程的求解,而分析化学专业人员通常不完全具备相关算法和编程知识。所以,尽管当前硬件发达、编程语言丰富,精确解析仍然难以在分析化学课程中大规模推广。为此,基于Matlab语言,开发了具有针对性的方程求解软件。该软件以简洁的界面、直观的图像和自然的人机交互,实现方程的高效求解;对用户的编程要求非常低。期望通过这种方式,显著降低化学平衡精确解析中的软件使用成本,从而为大规模推广提供进一步的支持。本文介绍了该软件的基本原理和主要特点;通过3个复杂化学平衡实例,详细说明软件的使用方法以及注意事项。另外提供Android系统版本,免费使用。
