Construction of e-Learning system with simulation tools developed by integrating Java and symbolic computation software

本研究的目的是将Java与符号计算软件相结合，开发仿真工具，并在电子学习系统上对外开放。计划如下：1；利用符号计算软件开发可在web上实现的仿真工具。结合符号计算软件和Java语言开发仿真工具。为个人数字助理（PDA）开发具有仿真工具的电子学习系统。我们将在下面进行更详细的描述。作为仿真工具的一个例子，我们开发了带有图形用户界面（GUI）的Maplet应用程序。Maplet是符号计算软件Maple的软件包之一。这些申请在网站上向公众开放。http://thomas.phys.cs.is.nagoya-u.ac.jp/Maple/App/As仿真工具2例，我们集成了Java语言和Maple。我们用Java开发了带有GUI的客户端软件，并与MapleNet服务器通信进行了一些计算。可以进行数值计算、符号计算和MathML输出。我们让学生开发一些简单的模拟工具，如这些应用程序作为作业。一些学生对开发这些应用产生了兴趣。课堂上使用的一些指南是对公众开放的。中村http://thomas.phys.cs.is.nagoya-u.ac.jp/ /网通/ ? % BD % E0%C8%F7。我们还提出了一种集成Java和Maple来开发仿真工具的替代方法。OpenMaple在Java程序中使用。3 .为了使PDA作为电子学习系统的客户端，采用了JSP技术。数字或符号计算可以与MapleNet服务器通信。任何具有JSP功能的PDA甚至手机都可以进行简单的仿真，该系统有望拓展PDA电子学习系统的可能性。

The purpose of this research is to develop simulation tools by integrating Java and symbolic computation software and open them to the public on the e-Learning system. The plan is as follows ;1. Development simulation tools using symbolic computation software that can be carried out on the web.2. Development simulation tools by integrating symbolic computation software and Java language.3. Development e-Learning system with simulation tools for a personal digital assistant (PDA).We describe in a bit more detail in the following.As an example of simulation tools 1, We developed Maplet applications with graphical user interface (GUI). Maplet is one of the packages of symbolic computation sofutware Maple. Those applications are opened to the public on the web site. http://thomas.phys.cs.is.nagoya-u.ac.jp/Maple/App/As an example of simulation tools 2, we integrated Java language and Maple. We developed client software with GUI by Java and the software carried out some calculations communicating with MapleNet server. Numerical computation, symbolic computation and MathML output are possible. We made students develop some simple simulation tools like those applications as an assignment. Some students got an interest in developing those applications. Some guide used in the class is opened to the public. http://thomas.phys.cs.is.nagoya-u.ac.jp/~nakamura/NetCom/?%BD%E0%C8%F7. We also suggested an alternative way to integrate Java and Maple for developing simulation tools. OpenMaple is used in Java program.As for 3, in order for a PDA be a client of e-Learning system with simulation tools, we adopted JSP technology. Numeric or symbolic calculation is possible communicating with MapleNet server. Any PDA and even a mobile phone which is capable of JSP can carry out a simple simulation and the system is expected to expand the possibility of e-Learning system with PDA.
