（寻找生活中更多有用的发明）鲁教版 九年级Unit 1 When was it invented? Section B 2b-3b
【教材分析】
本课教学的内容是鲁教版新目标九年级上Unit One When was it invented? Section B 2b-3b
本单元围绕“发明”的话题展开，Section A介绍了我们日常生活中一些常见物品的发明历史，本部分在A部分的基础上依然围绕发明创造这个话题，要求学生继续学习和巩固相关的内容和语言知识。听说和阅读训练分别介绍了现代生活中两项常见的发明：薯条和篮球。其中，篮球的发明是本节课的重点教学内容。
2a-2e部分是本单元的阅读训练板块。需要学生学习和掌握的阅读策略是利用思维导图帮助理清、记忆阅读语篇中的相关信息，把获取的信息转换成图形帮助记忆。3a-3b是单元写作板块，引导学生思考自己在生活中遇到的一些困难，要解决这些困难需要发明什么，这些发明的特点和用途是什么，鼓励学生大胆想象，放开思维，运用本单元学习的重点单词、词组、句型等来描述自己的发明，这是对学生综合语言运用能力的考察。
本节课共1课时，以教科书以依托，充分挖掘整合教材，做到源于教材，又不拘泥于教材，思维导图的运用使文章脉络清晰，降低难度，激发了学生的学习动机，提高了学生学习的积极性，让学生带着兴趣在轻松自在的氛围中学习知识，运用知识。

【课后反思】
本节课采用自我评价法，通过小组合作，鼓励学生积极参与课堂，以轻松活跃的课堂气氛取得最优的课堂效果，整体设计既能充分调动学生的积极性，又能让学生熟练掌握本节课的知识，，锻炼了学生的读、说、写等多种能力。
从课堂效果来看，总体符合当初的设计理念，复习环节和思维导图的运用环节，绝大部分同学能够积极参与，课堂气氛活跃。在谈论观点环节，由于任务设置的难度要高一些，学生之间的差距就明显一些，不能做到面向全体，基础较差的同学参与度和活跃度要相对低一些。在这一环节，采用小组合作，以优带差，能在一定程度上减轻基础差的学生的学习困难。写作环节也是一个难度较高的任务，学生独立完成的难度较大，因此，需要进行小组合作，集思广益，共同完成教学任务。从课堂反馈效果看，学生的语言表达能力整体还是不错的，会有少许的语法错误，教师也能够及时纠正，让学生明白出错的原因。
从目标达成度来看，本节课通过设置各种不同的活动，让学生进行情境学习，合作学习，探究学习，培养了阅读能力，目标达成度较高。
存在的问题：
谈论观点环节和写作环节任务设计的难度较高，没有达到分层教学，使得学生的课堂学习效果出现层次性；
小组之间的参与度和活跃度存在差异，在小组划分中应考虑下列因素：
小组合作应考虑学科特点，和小组成员间在本学科能力方面的差异。
考虑非智力因素的影响，如性格等。
在课堂上，教师应多关注不活跃的小组，多给他们机会。

2、过程与方法
在教学中，通过思维导图的运用，阅读技巧的点拨，逐步引导学生轻松高效的理解文章、谈论生活中的小发明。自我评价表使学生对本节课自己的课堂效果有清晰的认识，能发现自己在本节课的收获与不足，为课下的自我巩固提高指明了方向。
3、情感态度与价值观
通过学习篮球的发明，了解生活中其他有用的小发明，让学生感受发明给我们生活带来的乐趣，从而享受运动，享受生活，享受自我。
二、教学重难点：

四、整体设计思路：
本节课以思维导图贯穿始终，同时引入竞争和评价机制，将本节课大致分为五大部分，复习—预测—读—说—写，从七大方面进行评价，每一部分学完后，学生们可根据自己的表现得到一定数目的苹果，或根据所得苹果数判断自己的表现，让每个同学明白自己在哪一个环节有所欠缺，同时，也给每一个学生一个大胆展示自我的机会。提高学习的积极性。
