Abstract: Lead-in, as the first teaching step of a class, is called teaching organizing, one of the       most basic and important steps in English classroom teaching. However, only a little study was done home and abroad, and most of which was only about the experience of teaching without further theory to support. The lead-in approaches studied in this thesis are based on scientific theories concerning junior high school students’ development, cognition, motivation and interest. Through studying and analyzing different lead-in steps used by a few marvelous teachers in the teaching of English books, the study tries to give the direction to lead-in step teaching in the aim of improving class-teaching efficiency.

Key words: lead-in; strategies; classroom teaching

摘要:“导入”作为英语课堂教学的第一个环节——组织教学,是最基本的一个课堂教学环节。导入对一堂课能否顺利进行,能否圆满完成教学任务起着重要作用。然而,迄今为止国内外对课堂教学导入这一环节的研究颇少,且多停留在经验总结的层面上。本研究所总结的导入法以科学理论为基础，包括初中生的发展，认知，动机理论以及初中生的兴趣特点。从初中生心理视角出发所采取的有效导入策略能有效提高学生的学习兴趣，激发学习动机，促进学生积极思考并参与课堂活动。本文通过研究、分析极少数优秀教师在教授英语课本时所采用的不同课堂导入策略，分类总结了不同的英语课堂导入法，以期为提高课堂教学效率指引方向。
