导入新课是课堂教学环节中必不可少的一环,除了构成一个完整的教学体系和知识结构外,它最重要的作用就是引起学生的兴趣。如何把学生的注意力从课间玩耍的愉悦中、从上节课留在脑海的印象中、从紧张学习的疲累中吸引过来,让学生从身体、心理都进入本堂课的教学环境,并不是一件很容易的事情。但是,如果能够在这个环节中出色完成任务,那么就会收到“事半功倍”的效果。因此,如何设计一个极具实效性的导入是值得我们深入探讨和实践的重要问题。 The introduction of a new lesson is an indispensable part of the classroom teaching. In addition to forming a complete teaching system and knowledge structure, its most important role is to arouse students’ interest. How to draw students’ attention from the pleasure of playing in class, from the impression of the last class in mind, from the tiredness of tense study, to let the students enter the teaching environment of this lesson from the body and mind A very easy thing. However, if you can accomplish an excellent job in this session, you will receive the “less with less” effect. Therefore, how to design a highly effective import is an important issue that deserves our in-depth discussion and practice.
