探究動態類比對於科學概念學習與概念改變歷程之研究
－以國二學生學習氣體粒子概念為例－
論文摘要
類比與多重表徵在科學教育的研究上已經有很多研究說明兩者皆有助於學生學習抽象的科學概念，而本研究試圖結合「類比」與「動態表徵」發展出「動態類比」教學，意即是具有動態表徵的類比教學，主要研究目的是希望透過動態類比的實徵研究，探究學生氣體粒子之概念學習與概念改變。
本研究以國二學生（現行八年級學生）57人為研究參與對象，共分為三組教學。其中對照組20人，教學方式為教師口語與板書教學，教學過程中不使用類比與動畫；類比組19人，教學過程中使用樂透彩球類比教學但不使用動畫；動態類比組18人，教學過程中以動態表徵方式呈現樂透彩球類比教學，三組之中各有6人參與前測晤談與後測晤談。
本研究的量化分析之結果顯示動態類比組與類比組在氣體粒子概念的成就表現上優於控制組；而在概念本體屬性的分析上，動態類比組較類比組與控制組更能快速的建立全面的突現（emergence）本體屬性，類比也有助於突現本體屬性的建立，只是需要較長的時間與教學；另外一方面，本研究初探學生對於密閉容器內的壓力變化的心智模式結果分為五種主要心智模式：活塞運動施壓模式、感覺粒子很擠模式、粒子彼此碰撞模式、粒子碰撞氣壁模式與混合模式。質化研究結果顯示，動態類比組與類比教學組的學生在教學過後較對照組學生更能產生一致的科學模式，而對照組則以混合模式居多。
綜合量化分析與質化分析結果顯示，動態類比與類比教學有助於學生學習困難的氣體粒子概念，其中動態類比組的成效較類比組好，類比相對於對照組而言也有較佳表現，因此對於教育上的建議則是若有足夠的經費與技術支援，發展動態類比有助於學生學習困難的科學概念；若是經費不足或無適當的設備支援，類比也是一個良善且功效良好的教學策略與概念改變工具。

To inquiry the processes of students’s learning and conceptual change when they use dynamic analogy for learning
- An example of 8th students to learn the concepts about gas particles’ movement-
Abstract
Both analogy and multiple representations play very important roles in science education. So many researches have demonstrated that they can help students learn abstract scientific concepts. The purpose of this study is trying to combine Analogy and Dynamic representations for developing Dynamic analogy instruction, and inquiring the processes of students’ learning and conceptual change about the movement of ideal gas particles.
There were fifty-seven 8th students joining this study and they were been randomly assigned into three groups.：1.The comparison group, the instruction treatment in this group did not involve analogy and animation. 2.The analogy group, the instruction treatment was Lotto-analogy, but no animation. 3.The dynamic analogy group, the instruction treatment were both Lotto-analogy and animation. There were six target students interviewed within each group.
The results of this study were as follows:
First, the dynamic analogy group and analogy group had better achievement and had greater effects in conceptual ontology than comparison group. Though dynamic analogy group acquired all whole emergence attributes more quickly than analogy group, in other words, analogy group needed more teaching and learning time to adapt Lotto-analogy.
Second, in the quantitative analysis of target students’ protocol data, there were five major mental models which be defined in this study. These were (1. Plunger-Driving model, (2. Crowed-Particles model, (3. Particles-Collided model, (4. Walls-Collided model, (5. Mixed models. The results of qualitative analysis revealed that students in dynamic analogy group and analogy group used the scientific models more consistently across different context. In the opposition, the students in comparison group used mixed models when they encountered different problem context.
To combine the results of quantitative and qualitative analysis showed that the dynamic analogy group was better than analogy group, and analogy group had greater effects than comparison group. So, the Lotto-analogy was a powerful analogy for students to learn the conceptions of movement about ideal gas particles. Take these results into account, there are two suggestions for science education. First, if the educational budgets are sufficient, dynamic analogy should be developed to help students learn difficult and abstract conceptions of idea gas. Second, if the budgets are not sufficient, a well-designed analogy will be a good instructional strategy and a suitable tool for conceptual change.
