「素養」為核心的教育目標是當前教育的重點。在語文的教學與學習中，教材扮演著影響教與學成效的關鍵角色。國語文教科文本做為國語文教學的主要媒介，是否能達成前述「素養」導向的教育目標，或什麼樣的國語文教科文本助於達成前述目標，值得教育研究者關心與深究。以證據為基礎的研究是教育政策的重要基石。本研究整合論述與認知取向，兼顧文本與讀者特性，採取混合研究設計，探討國語文教科文本特性與教育目標的關係，以及對教與學的影響。

　　Literacy–based education is the goal of the current educational system. Curricular material plays a critical role for the effectiveness of language teaching and learning. As a major medium of teaching and learning reading, could the current selected texts in Chinese subject textbooks achieve the goal of literacy-based education? If not, what kind of texts could achieve that goal is worthwhile for researchers to investigate. Evidence-based research is an indispensible foundation for educational policies. Adopting a mixed-method approach by incorporating discursive and cognitive research method that take care of texts and readers, the current research aims to explore the relations between textual features of the current Chinese subject textbooks and educational goals, as well as their impacts on teaching and learning.
