    摘要: 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.
