摘要本文致力于研究如何在初中英语课堂中展开有效的导入环节。本文认为导入在初中英语课堂中扮演着不可或缺的角色。有效的导入能帮助一堂英语课堂更好的进行，也能帮助学生提高学习兴趣。并且本文认为有效的导入过程离不开心理学的运用。因为只有掌握了学生的心理，教师才能更好地展开教学设计和教学活动。因此本文通过结合皮亚杰认知发展理论中的同化、顺应和平衡三过程，分析作者在城南中学实习时所记下的几个教学导入案例，并根据同化、顺应和平衡三个过程提出有效导入应遵循的原则和各原则对应的有效导入方法。关键词：导入；初中英语教学；同化；顺应；平衡AbstractThis paper tries to figure out how to carry out effective lead-in in English class in junior middle school. As is known to us, lead-in plays a significant role in English class teaching. An effective lead-in can make an English class go on smoothly and it can also help the teacher arouse students’ interests of learning English. And the author believes that education is closely related with psychology. If a teacher wants to carry out his teaching design or activities successfully, he must make use of psychological theories. Therefore, this paper analyzes three teaching designs of lead-in from Chengnan Middle School, based on Piaget’s cognitive development processes--- assimilation, accommodation and balance. And the author comes up with three principles for effective ways of lead-in by using the three processes. And there are also several effective ways of lead-in according to each principle.Key words: lead-in; English teaching in junior middle school; assimilation; accommodation; balanceContentsAbstract........................................................................................................................II1.
