著名的樂高NXT的是一種低成本的機器人，可以很輕鬆地通過圖形用戶界面來組合製作，在台灣已成為一種流行的教學和學習工具而且被廣泛用於機器人教學。越來越多的樂高NXTs適用於不同的課程結合起來，為設計多媒體的教材。因此，了解影響教師在學校使用樂高NXT的意圖一直是渴望知道的研究課題，這是介以促進真實機器人學習材料和環境。
本研究是探討國小教師使用樂高NXT在傳統教學中作為輔助學習工具的意圖。研究者以科技接受模式（TAM），以及系統的特點和研究文獻所提到有關參與者提到的建議為基礎。研究者設計一假設模組。然後，收集47位來自高雄縣與屏東縣的國小教師。並以結構方程模式（SEM）為測試假設之工具。

The well-known LEGO NXT is a low-cost robot which can be easily programmed via graphical user interface and it is widely used for robotics education and has become a popular tool for teaching and learning in Taiwan. Eventually, more and more LEGO NXTs are applied to combine with different courses for designing multimedia instructional materials. Therefore, understanding the factors affecting teachers’ intention of using Lego NXT in school has been an eager research issue for the promotion of authentic robotic learning materials and environment.
The purpose of the current research is the exploration of teachers’ intention of using Lego NXT in elementary school where the system is used as a complementary learning tool within a traditional class. A model combining factors from Technology Acceptance Model (TAM) as well as system and participant characteristics cited in the research literature is proposed. Meanwhile, the operation of the LEGO NXT system is demonstrated first. Then, data were collected from forty seven elementary school teachers in Kaohsiung and Pingtung county. Structural Equation Modeling(SEM) is used to test the hypothesis.
