本研究以計畫行為理論(Theory of Planned Behavior)為基礎，針對某師範校院460 位職前教 師進行參與生態旅遊行為意圖模式之建構與探討，並利用結構方程模式(Structural Equation Model)統計方法對該模式進行適配度考驗與分析，進而瞭解職前教師對生態旅遊之看法，以期 提供未來政府將生態旅遊納入九年一貫課程實施之參考。研究結果顯示所建構之「職前教師參 與生態旅遊行為意圖模式」整體適配度良好；模式中「態度」與「主觀規範」對行為意圖均為 顯著的正向影響，「知覺行為控制」對行為意圖則是顯著的負向影響，其中以主觀規範(γ= 0.52) 對行為意圖之影響最大，態度(γ= 0.41)影響次之。而「主觀規範」變項對「知覺行為控制」變 項在參與生態旅遊行為意圖預測上有抑制關係的現象(Suppression Relation)。研究結果發現，當 職前教師個人對於參與生態旅遊所知覺到的困難程度越高時，其參與之行為意圖則為反向的。 此結果是否是職前教師特有的現象值得後續研究者針對其他師範校院職前教師做更深入與更 廣泛的比較與探討。

The purpose of this study was to apply the Theory of Planned Behavior to establish a behavioral intention (BI) model of participating in ecotourism activities by using Structural Equation Model for one Teachers College students. A total of 460 valid questionnaires were collected and the results were summarized as follows: 1. The proposed model was well fit pre-service teachers’ BI for participating in ecotourism activities. 2. “Attitude”, “Subjective Norm” and “Perceived Behavioral Control” variables were significantly correlated with the BI. “Subjective norm” (γ= 0.52) was the most effect variable toward the BI. 3. There was suppression relation between “Subjective Norm” and “Perceived Behavioral Control” regarding the BI for ecotourism involvement. Further exploration is needed that whether suppression relation was a phenomenon for pre-service teachers in attending ecotourism activities.
