摘要

本研究的目的在於建構網路虛擬化學實驗並評估虛擬化學實驗對學生學習的影響。
研究分成兩個階段，第一階段建立以國中理化課程『認識酸鹼指示劑』和『酸鹼中和』為實驗單元的虛擬化學實驗。經測試修正後，再進行第二階段的實驗及問卷調查。學生約有八成對系統的操作介面感到滿意。約有八成的學生自認對指示劑的變色機制更清楚，約有七成的學生自認對酸鹼中和的機制更清楚。經由實驗報告的分析，約有八成的學生能利用指示劑判別溶液的酸鹼性，而能完成酸鹼中和實驗並提出合理數據的學生約為四成。
本研究的虛擬化學實驗已具可用性，但仍有幾個地方可以改進。在動畫介面上讓畫面的顯示更美觀，更與實驗室的情況相符。在防錯機制上，如何將非預期的操作，納入系統的設計中，亦是一個改進的目標。

This study aimed to construct the network-based virtual experiments and evaluate the affection of students’ learning.
The first step is to construct the network-based virtual experiments, the acid and base indicators, titration, for junior high school students. Students’ views about these two experiments were analyzed in their satisfaction and understanding of theoretical principles. The findings reveal that about 80% students satisfy the interface of the system and approximate 70% to 80% students recognize these activities enhancing their understanding of the indicators and titration. Students realize the potential of network-based virtual experiments as a source of constructive feedback that enables them to take more responsibility on their learning.
