為符應學校多面向的發展策略及複雜的領導情境，學校中階領導者扮演承上啟下的關鍵性角色，在提高課程改革成效及落實課程改革理想上，深具意義。本文首先從新課綱下學校課程領導進行探討，再引進管理學中雙歧理論觀點，轉化應用於學校領導情境，探討學校中階領導者居中之角色與權衡組織複合領導情境所開展之雙歧領導任務，以釐清學校中階領導者於當前新課綱課程變革之意義與挑戰，實踐課程領導之角色與作為。本文最後提出：一、雙歧理論可轉化應用與學校領導情境；二、學校中階領導者兼具應用與探索的雙歧領導任務；三、學校中階領導課程發展任務有助於目標推動與價值澄清；四、學校中階領導者為落實新課綱課程改革實踐之關鍵。

In order to support the schools’ various development strategies and adapt to complex leadership situations, the middle managers play an important role to enhance the success of curriculum reform.

The middle managers of schools have both exploitative and exploratory leader tasks. 3. The ambidextrous tasks of middle managers contribute to the accomplishment of curriculum development. 4.
