校長的領導與教師的教學乃是影響學校效能的重要關鍵，因此校長如何透過有效領導凝聚成員共識，促進教師的專業成長，乃是不容忽視的重要課題。尤其在實驗教育三法公布後，學校面臨許多挑戰，更須妥為因應。其次，新課綱的實施乃是近年來臺灣教育界的重要議題，而欲達成此項目標，教師的教學觀念、態度與技巧必須有所改變，而此更有賴於校長教學領導角色功能的發揮，提供教師在教學上的支持，方能使教師教得更有品質、學生學得更有成效。本文主要在探究校長領導與教師教學支持之議題，全文共分三大部分：首先，分析校長領導與教師教學支持的關係；其次，探討校長領導與教師教學對落實新課綱的重要性；最後，則提出強化校長領導、落實教師教學支持的策略。

Principals’ leadership and teachers’ teaching are the key to school effectiveness. It is an important issue that principals can promote the professional development of teachers through effective leadership and pooling of consensus among members. In particular, with the promulgation of three experimental education regulations, schools face many challenges and must be properly responded to. Moreover, the implementation of the new curriculum is an important issue in the education sector in Taiwan in recent years. To achieve this goal, the concept, attitudes and techniques of teachers’ teaching must be changed, and this depends more on the role of the principals’ instructional leader, providing teachers with support in teaching which can help teachers to enhance teaching quality and students’ learning achievement. This article mainly explores the issues of principals’ leadership and teachers’ teaching support. There are three parts in this paper. Firstly, the relationship between principals’ leadership and teacher teaching support was analyzed. Secondly, the importance of principals’ leadership and teacher’s teaching to the implementation of the new curriculum was explored. Finally, the strategies for strengthening principals’ leadership and implementing teacher’s teaching support were proposed.
