在臺灣的技職教育體系中，職業學校群科課程綱要是教材編撰及課程設計的參考基準；而四技二專統一入學測驗是高職學生升學的重要依據。其中，統測共同科目英文考科中的對話題，採用了間接測驗來評量學生的口語能力。本研究旨在討論統測英文科對話題與高職英文課綱之吻合程度，及統測對話題的內容效度。為了達成此研究目的，本研究分析統測英文考科對話題型以及高職英文課程綱要，同時參考與測驗口說能力之相關教學研究及論文，發展出課綱檢核表及口說能力檢核表做為研究工具。 研究結果顯示，統測對話題與高職課綱中口說能力相關指標大致符合，但主題分佈不甚平均，主要強調日常生活情境下的溝通能力。就內容效度而言，其檢驗之能力多為基礎口語技巧，並且偏重測驗考生如何傳遞訊息及維持互動，並沒有包含處理互動的技巧。根據本研究之發現，筆者針對未來研究方向及測驗實務提出了建議。 / In the vocational education system in Taiwan, the Vocational High School Curriculum Guideline (VHSCG) is the basis of teaching materials and curriculum design, and the Technological and Vocational Educational Examination (TVEE) is an important reference for students to enter college. In the English test of the TVEE, an indirect speaking test was applied in the dialogue section. This research aims to investigate: (1) the correspondence between goals of speaking ability in the VHSCG and the dialogue section of the TVEE; and (2) the construct validity of the dialogue section. To achieve the purpose, this research analyzed the current curriculum guideline and the English tests of the TVEE, and studied the previous literature about assessing speaking ability to develop two checklists as instruments to analyze the targeted test items. Results indicated that the dialogue section of the TVEE generally corresponded with the speaking ability index in the VHSCG, but the topic distribution was imbalanced. The test items primarily focused on the communicative ability in daily-life contexts and was lacked of items that examine descriptive ability. For the construct validity, the dialogue section of the TVEE mostly examined fundamental speaking skills. Informational and interactional skills were strongly emphasized, while the skills in managing interaction were completely absent. Based on the findings of this research, the researcher yielded suggestions for future research and implications for the test developers.
