Abstract In the English classroom teaching, lead-in is not only the primary warm-up but also an important part during the whole teaching process。 A good introduction contributes to attracting and guiding the students to quickly focus on lessons。 However, influenced by the traditional wrong concept, the design and implementation effects are not satisfying in the lead-in part of English classroom teaching。 Based on relevant literature, this thesis focuses on the design and implementation of the lead-in part in the interactive English classroom teaching mode by putting forward four kinds of design in the lead-in part: question form, group discussion form, case analysis form and scenario simulation form。 Three main principles of lead-in: quality principle, quantity principle and angle principle have been summarized and four important steps of implementation have been put forward。 At the same time, some problems that should be paid attention to in the design and implementation of lead-in in interactive English teaching mode have also been summarized after combining with the teaching practice and experience。 The result of the research will enlighten and benefit the improvement of the effect of English classroom teaching。87094

论互动式导入在英语课堂教学中的应用

摘 要在英语课堂教学中,导入是整个教学过程的首要也是重要环节。一个良好的导入能够吸引和引导学生迅速进入学习状态。然而，受传统观念的影响，现在英语课堂教学在导入部分的设计与实施效果并不是很理想。因此，本文着重阐释了如何在初中英语课堂中设计互动式导入与实施。根据“质”、“量”、“度”原则，本文提出了问题式、小组讨论式，案例分析式以及情景模拟式四种重要的导入模式设计。其次，本文介绍了导入的四个重要实施步骤，并结合教学实践和经验总结分析了互动课堂导入的实施效果。最后，本文总结了在互动式英语课堂教学导入部分的设计与实施中应注意的问题，对提高英语课堂教学效果有一定的教学启示与借鉴意义。
