想像力是人類與生俱來，並引導個體從事創造思考與表現的重要能力。本文內含兩個研究：一為探究想像力的組合樣態；二則運用Rasch測量模型檢測「想像力量表」的客觀與等距特性。研究結果顯示，想像力主要由三向度能力組成，分別為：創始想像、構思想像、轉造想像。同時，創始想像內含探索、新穎、生產等三項特徵；構思想像內含有效、辯證、感受、直覺、專注等五項特徵；轉造想像則內含具象與轉用等兩項特徵。本研究開發之想像力量表凝鍊了眾多想像力特徵，具嚴謹驗證、易於施測之特性，其當可做為教師評估學習者想像力，亦可用於學習者自我引導之參考。

Imagination is an important human capability which inspires individuals to engage in creative thinking and performance. Two studies were combined to examine the imaginative capability and to test an instrument regarding this capability by using the Rasch modeling analysis. The results indicated that imaginative capabilities consisted of three components, namely initiating imagination, conceiving imagination, and transforming imagination. Initiating imagination consisted of three characteristics: exploration, novelty, and productivity. Conceiving imagination consisted of five characteristics: effectiveness, dialectics, sensibility, intuition, and concentration. Transforming imagination consisted of two characteristics: crystallization and transformation. The current study provided intriguing insights into the characteristics and categories of human imagination. The imaginative capability scale was developed to be both empirically valid and easy to administer in diverse domains. The results seem productive enough to warrant further inquires and to be used in both teachers’ instructional evaluation and students’ self assessment.
