Teaching A level physics through microcomputer dynamic modelling: Evaluation of teaching

Abstract  This paper describes an evaluation of teaching A level Physics through dynamic modelling. This teaching was carried out with a group of 12 lower sixth Nuffield A level Physics students and was evaluated with three tests internal to the school and with the external public Nuffield A level Physics (NAP) examination which those students later took. The internal school tests showed that the treatment group performed better than an equivalent non-treatment group in both general ability and in a few particular skills. The public NAP examination showed no superiority of the treatment group, but indicated a significant preference for an optional question that involved mathematical skills, even though none of the treatment group took mathematics at A level. Comments are made about the educational significance of dynamic modelling and about computers in education generally.

Cybernetic jewelry: ornament for the information age

Although jewelry has historically been equated with hardware, the advent of the single-chip CMOS microcomputer allows a redefinition in terms of software. A radically different new kind of jewelry is presented, based on LCD graphics controlled by an on board microcomputer. The revolutionary potentials of this new jewelry, along with its unique requirements and problems, are illustrated by examples from the author's personal experiences in developing this novel medium.     

一种简易的微机开发系统

本文介绍的开发系统由TRS-80微型机和TP801-280单板机组成,不需增加任何器件。软件开发在微机上进行,可以采用汇编、FORTRAN或二者混合编程。编译产生的目的文件可被装入和并行传送到单板机在线模拟或写EPROM。并介绍了系统连接和有关软件。最后以一个开发实例简述了系统的应用。     

二维弹塑性有限元程序PLANET的微机化改造

本文介绍了一个二维弹塑性有限元程弃ＰＬＡＮＥＴ的微机化改造，通过将该程序的链式结构改变为并列模块结构，并改进内存空间的数据存储方式，使得该程序能够在普通微机上求解大，中型工程问题。此外，为了提高数据准备和成果整理的工作效率，还对该程序的数据理论入和输出系统做了改进。最后，给出两个计算实例以检验程序的计算精度和解题能力。     

样条函数在补偿中子算法中的应用

本文从对补偿中子测井实验刻度点的讨论出发,提出用样条插值方法而不是通常回归拟合方法来构造补偿中子响应方程。样条函数采用分段的多项式。文中指出,四点三次样条插值是其较为实用的形式,这时插值多项式参数计算的解析式容易导出,实时处理中求视孔隙度的计算量完全可为一般采用软件作数值运算的微处理机系统所接受;并提出补偿中子测井的刻度方法,这种算法极大地简化了井下仪的调校;对水点取值也进行了讨论。附录中给出求解参数的具体计算公式,可以此作为上机编程的依据。     

Introducing microcomputers to managers in the people's Republic of China

Having set up the first microcomputer laboratory in China, the authors provided 178 Chinese professionals with course-work lectures, and workshops designed to increase their understanding of the potential for using microcomputers in their organizations. This paper assesses the impact of those educational experiences on the Chinese students' perceptions of how they could apply the PC to their organizations, what uses they would make of a PC, what services a PC would require, and how soon they expected to be using (to adopt) a PC. Analysis of appropriate data takes into account such factors as differences in the content of the educational experiences and differences in the amount of time the students spent actually using the PCs. Analysis indicates that the educational experiences did significantly increase the Chinese students' perceptions of possible applications and uses of PCs in their organizations and provides evidence that similar educational experiences could be most effective in introducing microcomputer technology in countries such as China.
