本研究主要探究提升國小學童英語字彙學習能力之影響因素，首先進行文獻蒐 集，參考相關文獻後，運用修正式德菲法，得到四項構面因素，教學理論、教學風 格、教學工具及學習動機。建立層級架構後，接著透過層級分析法(AHP)求得此四項 構面的相關指標因子，並建立起權重體系。
綜合上述，本研究於四項主要層面中，「學習動機」為影響最顯著之指標，其次 為教學風格、教學工具，權重最低則為教學理論。而若以十五項次要準則來看，「學 習參與度」、「學習中心型」、「學習任務」為較顯著因素。這也反映了學生為學習的 主要考量，教學的過程為協助學生學習能力的獲得。

This study mainly investigated into the influential factors of enhancing English vocabulary learning ability of elementary school students, gathering and referring to relevant literature and the application of modified Delphi method (MDM). Four factors which are teaching theory, teaching style, teaching material and learning motivation, respectively were obtained in this study. A hierarchical structure was established, and then the Analytic Hierarchy Process (AHP) was applied to finding the relative index factors of the four aspects and to build up the weights for the hierarchy model.
Based on the four main criteria in this study, the results show that the most significant indicator is “learning motivation”，followed by “teaching style”，“teaching material”，and at last "teaching theory”. In terms of fifteen sub criteria, learning participation, learning center and learning task are more important than other factors. This also reflects that students are the primary consideration in learning, and the teaching process is to assist students to obtain learning ability.
