The design teaching that pursues concept understanding is based on promoting students'deep understanding and is a literature-oriented teaching.Collaborative thinking is an important way to understand concepts.Concept-based teaching is idea-centered rather than knowledge-centered.Collaborative thinking is the combination of factual and conceptual thinking,prompting students to gain a deep understanding and transfer thinking to other times,places and situations.Taking ancient poems as an example in Unit 5 of the Seventh Section,by guiding students to find and understand the common points of these poems with specific reading strategies and skills,they can think together with the understanding of the content of specific poems and the conceptual understanding of the important expression techniques of such poems,so as to further understand this concept and apply it to the reading of other poems,which embodies the value of concept-based teaching.
