SYSTEM DEVELOPMENT FOR UNDERSTANDING THE GRAVITY CONCEPT

以下三个微观世界是假设在学习者谁是思考的重力。1：世界思考的话，例如，“快，这个重量，速度，ets。“.2：3.图表思维世界，以“二维空间x-y”为例，在上述微世界的基础上，设计了相应的窗口，并考虑了在这些窗口上的学习活动，利用Microsoft Visual Basic开发了语言窗口、方程窗口和图形窗口。此外，本系统还开发了动画窗口，以支持学习者的动态运动图像，本系统是作为一个工具开发的，与学习者的任务相分离。该工具不仅可以帮助学习者思考，还可以帮助教师演示。作为该窗口系统的应用，在图形窗口、方程窗口和参数窗口中展示了二次方程：y=ax（x-b）。通过这些例子，得到了以下结论。1.连接系统的窗口可以作为一个学习环境。它可以由学校教师用面向对象的程序设计软件开发.微世界理论为开发Windows的连接系统提供了一种策略。

Following three microworlds were supposed in learners who are thinking about the gravity.1 : World for thinking with words, for example, "fast, this weight, velocity, ets.".2 : World for thinking with equations, for example, "f=m * alpha".3 : World for thinking with graphic charts, for example, "two dimensional space x-y".On the basis of microworls above, respective windows were designed.Learing activities on these windows were considered.By using Microsoft Visual Basic, lingustic window, equational window, and graphical window were developed. Additionally, animation window were developed for supporting learners' dynamic image of motion.This system were developed as a tool, separated from tasks for learners. This tool can be utilized not only for helping learners'thinking but also for helping teachers'presentation.As an application of this window system, an equation of the second degree : y=ax (x-b) was presented in graphical, equational and parameter windows.By these examples, following conclusions were obtained.1. Connected system of windows can be used as a learning environment.2. It can be developed by school teachers with object-oriented programming software.3. The theory of microworld provides a strategy for developing connected systems of windows.
