Development of Authoring Tool for Educational Simulation

我们将教育模拟分为四类：1)表驱动模拟：对象的位置由x-y表控制；2)确定性模拟：对象的位置由数学方程控制；3)概率模拟：对象的位置由概率决定；4)竞争性模拟：策略由对手对象的位置决定。在本研究中，我们开发了1)和2)模拟的模拟执行器。执行器是用C++语言开发的，称为面向对象的计算机语言。(1)快的执行速度是移动最多20个对象的必要条件；(2)对象的独立性有助于定义每个对象的规则；(3)容易将执行器的代码从NEC翻译成DOS/V和其他机器。模拟程序将用7条指令和几个参数来描述。这是1)！帝司(！显示)，2)！Seigyo(！控制)，3)！对象(！对象)，4)！Jikko(！执行)，5)！Nyuryoku(！输入)，6)！Shuryo(！完)，7)！秋沙库(！使用这些指令，教师可以很容易地描述仿真程序。我们科学项目的一位初中教师在1小时内制作了一门李萨举课程。他最终用10行文字描述了李萨举仿真。仿真执行器的特点是：1)仿真软件在几种不同的机器上兼容。2)开发了三种类型的自动控制系统(动画、数学函数、场和运动)。3)教师可以使用习惯的文字处理器或编辑器来描述仿真软件。4)学习者可以通过在对象上附加测量功能来测量x-y。然后，他可以使用电子表格类型的软件轻松地分析对象的运动。

We have classify Educational Simulations into 4 categories.1) Table driven simulation : Positions of Objects are controlled by x-y table.2) Deterministic simulation : Positions of Objects are controlled by mathmatical equations.3) Probability simulation : Positions of Objects are determined by probability.4) Competitive simulation : Strategy is determined by the position of a opponent object.In this research, we have developed simulation executor for simulations of 1) and 2) .The executor was developed by C++ language which was called the object oriented computer language.The reasons were as follows ;(1) the fast execution speed was nessesary for moving maximum of 20 objects,(2) the independence of objects was useful for defining the rule of each object,(3) easy to translate codings of executor from NEC to DOS/V and other machines.Simulation programs will be described in 7 instructions and several parameters.These are 1) ! Teiji (! Display) , 2) ! Seigyo (! Control) , 3) ! Object (! Object) , 4) ! Jikko (! Execute) , 5) ! Nyuryoku (! Input) , 6) ! shuryo (! End) , 7) ! tyushaku (! Comment) .Using these instructions, a teacher can describe simulation program quite easily.One lower secondary school teacher of our project in Science made a Lissaju course within 1 hour.He finally described the Lissaju simulation in 10 lines.The characteristics of the simulation executor is ;1) Simulation software is compatible within several different machines.2) Three types of autoring systems have been defeloped (for Animation, Mathmatic Functions, Field and Motion) .3) A teacher can desribe simulation software using accustomed Wordprocessor or Editor.4) Learners can measure the x-y coordinated by attaching measurement function on the object. Then he can easily analyze the motion of the object using spread sheet type software.
