作为一门以习近平新时代中国特色社会主义思想为理论基石的学科，思想政治课程承载着新时代的教育方针与教育思想，是国家意志在基础教育领域的直接体现，具有学科内容的时代性、德育工作的引领性、课程组织的实践性等特征。新课程标准强调要改进教学方式和学习方式，教学过程注重师生互动、开放民主，活动型学科课程的开展势在必行。议题教学作为落实活动型学科课程的重要抓手走进大众视野，依托问题情境、借力社会实践，促进学生在合作探究中培养合作意识、创新精神、实践能力。

本文选取议题教学及其在高中政治课堂师生互动中的实践教学为研究对象。首先介绍了高中政治师生互动与议题教学的相关理论，主要阐述了师生互动的概念、特征与理论基础，阐明了议题教学的概念、特征。其次，论述了高中政治师生互动的重要性与议题教学对改进师生互动现状的优势。再次，通过问卷调查剖析我校政治课堂师生互动存在的问题并分析原因。最后，以“更好发挥政府作用”为教学案例，提出议题教学在改进师生互动现状中的实施路径，即课前准备阶段(精设议题、精编导学案)；课中教学阶段(议题导学、议题讨论、展示分享)；课末总结阶段(议题升华、静悟深思)。同时，分析议题教学效果，并提出议题教学并非解决师生互动问题的万全之策，还需要其他教学方式的配合。本文注重建构良好的师生互动结构、培养民主开放的新型师生关系，促使政治认同、科学精神、法治意识、公共参与的学科核心素养落地课堂。

The teaching process focuses on teacher-student interaction, openness and democracy, and the development of active subject courses is imperative. As an important starting point for the implementation of active subject courses, topic teaching enters the public view, relying on problem situations and leveraging social practice, to promote students to cultivate cooperation awareness, innovative spirit, and practical ability in cooperative inquiry.

This article selects the topic teaching and its practical teaching in the interaction between teachers and students in the high school politics classroom.Firstly, it introduces the relevant theories of political teacher-student interaction in high school and topic teaching. It mainly expounds the concept, characteristics and theoretical basis of teacher-student interaction, and clarifies the concepts and characteristics of topic teaching.Secondly, it discusses the importance of high school political teacher-student interaction and the advantages of topic teaching to improve the status of teacher-student interaction.Thirdly, it analyzes the problems existing in the interaction between teachers and students in our political classroom through questionnaires and analyzes the reasons. Finally, taking "better government role" as a teaching case,   It puts forward the implementation path of the topic teaching to improve the status of teacher-student interaction. That is, the pre-class preparation stage (set topics, fine-tuned case studies),the teaching phase of the lesson (topic guidance, topic discussion,display sharing),the summary stage at the end of the lesson (sublimation of topics, reflection of Jing Wu).At the same time, it analyzes the effects of topical teaching and proposes that topical teaching is not a complete solution to the problem of teacher-student interaction. It also needs the cooperation of other teaching methods.It focuses on constructing a good teacher-student interaction structure, fostering a democratic and open new type of teacher-student relationship, and promoting the core discipline of political identity, scientific spirit, awareness of the rule of law, and public participation.
