本研究之目的旨在探討如何應用概念構圖於化學概念學習之上，並對概念構圖在學習評量上之應用，進行幾項議題之探討，包括:(一) 探討透過何種概念構圖模式能更真實有效的反應出學習者相關化學知識內涵與結構？(二) 探討運用概念構圖的教學與學習模式，是否能更有效的達到化學概念改變的目的？(三) 探討如何將其他教學或學習模式與概念構圖模式相結合，以期更有效地讓讓學習者達到化學概念改變的目的？本研究之研究單元為有關「游離能」之相關化學概念，研究工具除概念構圖外，尚包括二段式選擇測驗，利用多元之研究工具，藉以發掘學習者之迷思概念
進而發展更有效的教學模式以澄清其迷思概念。

The aim of this study is to explore how infusing concept mappingtechniques
into learning chemistry concepts, and also to discuss issues related as followings:(I) To investigate by which way the concept mapping techniques could more efficiently reflect the intrinsic chemistry knowledge and structure owned by students?(II) To explore whether concept mapping techniques could efficiently achieve the end of concept change.(III) To find which way combined with the concept mapping techniques could more
achieve the end of concept change.The “ionization energy” was the topic to be discussed in this study. There include a two-tier multiple selection test as the research tool, concept mapping techniques besides, to dig out and clarify students’ misconceptions.
