Abstract:	本研究以問題導向的電腦化教材，協助學生在圓周運動作觀念的了解。藉著「觀念衝突」的教學策略，引發學生對自己學習狀態的了解及學習新知識的動機，從而協助學生自行解決圓周運動的問題。在活動中，學生先對問題作自己的預測及解釋，在回答一系列的引導問題後，再做一次預測，並與先前的預測做比較。研究結果發現，在學生解題能力方面，使用電腦教材的學生成績顯著優於未使用電腦教材的學生。在觀念理解方面，使用電腦教材可幫助原本能力顯著較低的學生與原本能力較高的學生達到相同的水準。物理先備經驗的多寡與平日使用電腦的頻率則對學生在電腦化學習環境中的學習成就沒有顯著影響。 The problem-based computer instructional material was developed to help students improve qualitative understanding about circular motion. Through the "conceptual conflict" strategy, students identified their own understanding about circular motion and then solved the problem by themselves. In the activity, students were first asked to predict the forces and accelerations at various times and positions and to provide their explanation. Then they were given a series of questions and were asked to analyze their own answers to solve the problem. The teacher, as a facilitator, used Socratic dialogue to provide more help for those groups who needed. For problem solving ability, students who used computer simulations scored significantly higher than those who did not use computers. For conceptual understanding, on the pretest, students in the computer group scored significantly lower than students in the non-computer group. On the post test, there was no significant difference found between the two groups. Student prior physics experience and frequency of computer uses did not have effects on student achievements in the computerized learning environment.
