「大學教師教學魅力量表」之發展

The Inventory of Teaching Charisma in the College Classroom

本研究之主要目的在發展「大學教師教學魅力量表」（Inventory of Teaching Charisma in the College Classroom， ITCCC）。發展過程首先參酌相關文獻，並彙整訪談學生意見據以編製量表，再以265 名大二學生進行預試，而後以項目分析篩選題項。正式施測後共獲得1，035 份有效問卷，將其隨機分為三組，分別進行探索性因素分析、驗證性因素分析，以及複核效化分析。探索性因素分析的結果共抽取出四個因素：人格修養、幽默風趣、學識涉獵，以及教學技巧；總量表的Cronbach’s係數為.962，分量表介於.898至.927之間。驗證性因素分析結果發現，ITCCC模式有合理的適配及良好的效標關聯效度，而且ITCCC 的四個一階因素具有合理的組合信度與變異數平均抽取量，可見ITCCC 具有良好的信度與效度。最後，經由複核效化分析顯示，量表模式具有跨樣本的穩定性。

The main purpose of this study was to develop the Inventory of Teaching Charisma in the College Classroom (ITCCC). The initial items were built based on reviewing the relevant literatures and informal discussing with students. The formal scale was obtained by 265 pilot study samples of sophomores and items analysis. The valid 1，035 participants were randomly divided into 3 groups to perform exploratory factor analysis， confirmatory factor analysis and criterion-related validity， and cross-validation examination， respectively. After exploratory factor analysis， four factors - morality， humor， knowledge， and teaching techniques - were extracted. The Cronbach’s coefficient for the entire scale was .962， and the coefficients of internal consistency for four subscales ranged from .898 to .927. The results from confirmatory factor analysis suggested that the ITCCC has good goodness of fit and criterion-related validity; moreover， the four factors have good composite reliability and average variance extracted. The ITCCCtherefore had good reliability and validity. Finally， the cross-validation for the model was examined on the third sample set.
