项目摘要

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.

在思考重力的学习者中应该有以下三个微世界。1：世界用文字思考，例如，“快，这个重量，速度等”。2：用方程思考的世界，例如“f=m * alpha”。3：用图表思考的世界，例如“二维空间x-y”。在上述微世界的基础上，设计了相应的窗口。考虑了在这些窗户上的学习活动。利用Microsoft Visual Basic开发了语言窗口、方程窗口和图形窗口。此外，还开发了动画窗口，以支持学习者的动态运动图像。这个系统是作为一个工具开发的，与学习者的任务分开。这个工具不仅可以用来帮助学习者思考，也可以用来帮助教师的演讲。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给出了二阶方程y=ax （x-b）。通过这些例子，得出了以下结论：连接系统的窗口可以作为一个学习环境。它可以由学校教师使用面向对象的编程软件进行开发。微观世界理论为开发窗口互联系统提供了一种策略。
