摘要

本研究將自由體圖分成兩大類。將支座反作用力及輔助方程式做成資料庫。用平衡或運動方程式與輔助方程式解各種問題。並依據網路輔助教學研究之原理，使程式具多種學習方式及不同學習回饋的功能及兼具電子書和網路遠距教學等效用，期待對教學及研究有所助益。
本教學程式架構如下：
1.電子書
（1）教材：展示整理好的重點。
（2）備忘：紀錄題型解題步驟，以供使用者參考。
2.電腦輔助教學
在三個教學單元下依照不同的教學回饋方式分為 （1）學理說明；（2）學理測驗；（3）教學例題；（4）教學測驗；（5）測驗篇；（6）模擬篇。其內容編排為依垂直思考法編寫解題步驟，再依水平思考法將解題方法及重點提示展示給學生了解。經由時間效應，達到反覆學習的作用，讓使用者了解自由體圖。
3.網路
即研究室網站，提供學習者提出疑問的管道與公佈研究室的最新消息等。
本研究對自由體圖分析做統整研究，以幫助學生對自由體圖的繪製與相關的解題技巧有整體觀念。相信對學生學習、升學有所幫助。

This research analyzes two units of free body diagram. Make a data bank for support reacting forces and auxiliary equations. Use equilibrant or motion equations and auxiliary equations to solve any kinds of questions. According to the theory of C.A.I., the program applies multiple processes for learning, accessible interface to students for different feedback of learning, and provides electric books and distant educations. We hope it would be useful for teaching and research.
The structure of the software program is as follows：
1. Electron Book
(1) Teaching material: It displays the point of the sorting.
(2) Memorandum: Note down the solution approach about the questions for user’s reference.

2. C.A.I.
According to different feedback of the teaching, it under three parts be divided into (1) Basic academic theories; (2) Examples description; (3) Formula proofs; (4) Teaching chapter; (5) Test chapter; (6) Simulation chapter. Its content is arranged according to vertical thinking to write solving steps and according to lateral thinking to display the solving methods and points. Let the student understand free body diagram by a lot of practice.

3. Network
It is a website of the laboratory. The websit that user can ask question here, and it announces the latest news of the laboratory.

This research has integrated the teaching material of the free body diagram to help the students know how to draw the free body diagram and solve the equation. It must be helpful for students to learn, to advance to a higher school.
