八年级英语（下）Lesson30Keepthecandleburning!教学设计

1、 Lesson 30 Keep the Candle Burning ! 教学设计一、教材依据：本课为冀教版八年级（下）Unit 4 Look into Science ( Lesson 30 Keep the Candle Burning !)二、设计思路：1.指导思想：深入贯彻新课程标准，应用“先学后导，问题评价”教学模式，以问题发现生成解决为主线，以问题评价为手段，以任务驱动为问题解决途径的教学模式。在教师指导下使学生和教师以问题发现为主线进行评价性的自主合作学习，对生成问题进行互导性的合作探究学习，以此激发和培养学生学英语的兴趣。同时培养学生结构化预习习惯，发展自主学习的能力和小组合作

2、学习意识；充分调动全体学生的学习积极性，使学生树立自信心；放手大胆让学生展示，使学生掌握一定的英语基础知识和听、说、读、写技能，形成一定的综合语言运用能力；培养学生的观察、记忆、思维、想象能力和创新精神。2.教材分析：本课为冀教版八年级（下）Unit 4 Look into Science ( Lesson 30 Keep the Candle Burning !) 本课通过谈论实验器材、实验步骤、实验现象，激励学生用英语描述实验并尝试着做实验，以激发学生热爱科学的兴趣。要求学生掌握match, burn, light ,use up等词的用法，理解应用stop doing sth. stop

3、 to do sth. keep sb.( sth. ) + adj. keep sb.( sth. ) doing 及分数的表达法。3.学情分析：高效课堂教改实验实施一年后，学生已经适应了这种教学模式。课前能自觉地进行结构化预习，课堂能积极主动地参与小组讨论及展示活动，认真听讲的同时还能反问或质疑。小组内，学科长认真负责，不但能及时检查两单、而且课堂讨论组织的有条不紊。学生逐渐由“懒惰型”向“勤奋型”过渡。但部分学生由于对前面所学词汇掌握不牢固，知识欠账严重，学习上有所掉队。另外部分学生记笔记的习惯较差，不能记录下本节课知识点，导致课后无法进行再学习。英语 学科新课程高效课堂导学案授课年级八
