1、 二、课题:八年级英语（新目标）下Unit 3 What were you doing when the UFO arrived ?Section A （1a2c） 三、教材分析 本单元教学以“不明飞行物到达时你在做什么,”导入，围绕“谈论过去发生的事情”这个这个话题展开教学，引导学生通过学习本单元的语言素材看图说话、句型操练、实际描述、对话表演，使学生学会用英语讲故事。这个话题贴近学生的生活，让他们有话可说。本单元的教材特点是话题集中，但句型不多。主要语法内容为when 引导的时间状语从句及过去进行时。我选取的是本单元的第一个课时，本课出现了大量的地点名词（短语）;一些实意动词;学习过去进行

I had nothing to do. I slept again . 六、教学反思 针对上述教学设计和具
22、体的教学活动，笔者事后又一下几点思考:垂直于切线; 过切点; 过圆心.一、好的方面 1、飞碟和外星人对于学生来说是新鲜事物，通过看外星人登入的视屏来导入新2、会数，会读，会写100以内的数，在具体情境中把握数的相对大小关系，能够运用数进行表达和交流，体会数与日常生活的密切联系。课，使学生对学习充满兴趣并感受英语学习的乐趣，从而营造良好的课堂氛围。2、在学习生词和短语时通过CAI辅助予真实的情景来呈现，把单词和短语放在2. 俯角：当从高处观测低处的目标时，视线与水平线所成的锐角称为俯角具体的语境中学，避免了学习生词和语法的枯燥无味。通过小组合作，操练句型，二、学生基本情况分析：包括语法点when
23、 和while在用法上的不同之处的讲授（通过大家一起观察，再6 4.24.8 生活中的数3 P30-35总结，老师点睛）等都把课堂真正还给了学生，让学生成为演员，而老师只是节目主持人，这充分的体现了老师为指导，学生为课堂主人的主体地位。提高了课设O的半径为r，圆心O到直线的距离为d；dr 直线L和O相交.堂的效率。五、教学目标：3、本节课从教学内容安排到教学各环节之间的衔接以及重、难点的设计等方面还算是比较合理自然的。如笔者对教材进行了整合，把2a 部分放在开头，和导入很好的衔接，而 2b 部分先让学生试着去观察语法焦聚，在猜测when 和while 的用法，再播放听力来核对他们的答案。培养了
24、他们的自主学习的能力（观察），又训练了听的能力。之后的听力材料跟读和齐读，训练他们读的能力。课后的写作任务可以很好的训练学生写的能力。4、本节课的内容中有知识的呈现，也有知识的操练，更有知识的巩固，用讲练相结合的方法，使新知识得到更好的吸收。而游戏的设置可以缓解下课堂，给课堂带来新的生命和活力，同时又可以操练巩固对话内容，培养了他们说的能力。二、要改进之处 1、任务型教学要求学生在教学中不仅要关注学习的结果页要关注学习的过程。学生完成学习任务的过程就是发现问题、思考问题、解决问题的过程，要注重形成性评价。而笔者在教学过程中没有注重这一点。本册教材在第五单元之后安排了一个大的实践活动，即“分扣子
25、”和“填数游戏”。旨在综合运用所学的知识，从根据事物的非本质的、表面的特征把事物进行分类，发展到根据客观事物抽象、本质的特征进行不同方式的分类，促进孩子逻辑思维能力的发展。同时，安排学生填数游戏，旨在对孩子的口算能力、逻辑思维能力和观察能力的训练，感受数学的乐趣!2、在教学中恰当的引入竞争的学习机制可以使学生学习热情高涨，培养学习激情，感受成功的乐趣。而我没注意到这点，所以事先应该设计诸如小组或男女生竞赛这样的活动。3、课堂用语中掺杂的汉语比较多。这主要与平时授课多说汉语有关，今后在教学中药注意纠正这个习惯，让学生更多地区感受英语，同时也带头引导学生尽可能多使用英语。4、在反思中成长，反思是实践的一面镜子，每次教学反思都能折射出教学的成功和不足，只有汲取成功的经验，改进不足，才能不断提高课堂教学的质量，保证教学任务的圆满完成，成为一个成功的引领者。
