人教八年级英语(上册)Unit 6 Section A(1a-~1c)授课教案设计

Unit 6 I'm going to study computer science.一、教学内容分析本节课的教学内容是人教版新目标八年级英语上unit6 I'm going to study computer science.的第一课时1a-1c。

本课位于人教版八年级上第6单元的第一部分，其主要内容就是学习关于职业的单词以及be going to的用法，用一般将来时谈论未来自己与他人理想的职业及原因，为实现理想所做出的打算和安排，以及制定未来一段时间内的学习计划。

目的是通过对人生理想的讨论使青少年在这个如花的季节不仅对未来有美好的憧憬，而且要从现在做起，为健康的理想而奋斗。

二、教学目标(1).知识目标: 要求学生掌握关于职业的名词computer programmer, computer science, engineer, pilot, professional ….本课主要句型：What are you going to be when you grow up? I’m going to be an engineer. How are you going to do that? I’m going to study math hard.语法：用be going to表示一般将来时。

(2).能力目标：能听懂有关人生理想的词汇及表达；能听懂有关未来计划的表达；能进行有关人生的谈话；能进行有关将来计划的讨论。

培养学生应用英语谈论将来计划，提高学生听、说、读、写等能力。

（3）情感目标：通过对人生理想的讨论，让学生从小就树立自己的人生理想，并且现在就下决心，为理想而努力奋斗。

使他们成为有理想，有抱负，有动力，健康成长的新一代青少年。

三、教学重点、难点。

（1）重点词汇：要求学生掌握关于职业的名词computer programmer, computer science, engineer, pilot, professional ….（2）重点句型：本节课要求学生掌握并能够正确运用：What are you going to be when you grow up? I’m going to be an engineer.How are you going to do that? I’m going to study math hard.（3）难点：一般将来时be going to 中be 的具体形式和后面接动词原形的用法学生容易混淆. 学生根据自己喜欢的职业，运用所学知识谈论自己打算怎样做来实现目标则既是难点，又是能力训练点。

二、学情分析
八年级的学生已经具备了一定的英语基础，对一般现在时态和基础词汇有一定的掌握。在此基础上，他们对新鲜事物充满好奇，喜欢参与课堂活动，表现出较强的学习积极性。然而，在语言表达和听力方面，学生仍存在一定的困难，需要教师在教学中给予关注和指导。
在本章节的学习中，学生可能对新词汇的掌握和应用存在挑战，特别是关于志愿者活动和慈善事业的词汇。此外，一般现在时态在描述人物特点和行为方面的运用，对学生来说也是一个难点。因此，教师应结合学生的实际水平，采用生动形象的教学方法，帮助学生克服这些困难。
3.教师布置课后作业，要求学生运用所学知识进行实际运用。
师：For homework, I want you to write a short passage about a volunteering activity or charity using the simple present tense. Try to use as many new words and phrases as you can.

英语人教版八年级上册Unit6SectionA（1a-1c）课程教学设计

英语人教版八年级上册Unit6SectionA（1a-1c）课程教学设计Unit6 I’m going to study computer science.Section A(1a-1c)教学设计一、教学目标：(一)知识与技能1、能掌握本节课所学习的单词如：computer programmer、engineer、bus driver、basketball player、pilot、scientist、violinist、pianist、actor、actress及短语grow up和be going to.2、能熟练运用句型：A : What do you want to be when you grow up?B : I want to be a/an……A : How are you going to do that?B : I’m going to……及用第三人称单数形式来进行问答。

（二）过程与方法1、通过听说练习，能学会关于职业的单词和短语。

2、通过游戏活动和大量的对话练习，能谈论未来工作的打算。

（三）情感态度和价值观通过描述职业，表达自己的看法，使学生在人际交往中学会尊重别人，能交换不同的看法，增进情谊。

同时让学生们知道要想实现梦想职业必须通过自己的努力，遇到困难不要放弃。

二、教学重点、难点重点：be going to表示一般将来时难点：一般将来时be going to中的be的具体形式和后面接动词原形的用法，而学生根据自己喜欢的职业，运用所学知识谈论自己打算怎么做才能实现目标既是难点，又是能力训练点。

三、教材分析本节课是第六单元第一课时，主要学习的内容就是如何用英语谈论职业及打算。

以及重点句型”want to be”、“be going to”。

本节课要求讲到2C部分，但是考虑到我们农村学生的实际情况，这节课我只设计到1C，把下一节课需要掌握的第三人称单数变化提前设计到这节课中，让学生的能力得到提升。

人教版八年级英语上Unit 6 Section A (1a-1c)教案教学设计

人教版英语八年级上Unit 6 I’m going to study computer science.教学设计一、课型：听说新授课二、教学资源分析本课是新目标英语八年级下册第九单元Unit 6 I’m going to study computer science.本单元中心话题是“谈论人们的工作特征”，《英语课程标准》（2017版）要求学生会用英语流利地表达自己对工作的感受和想法。

主要针对如何询问及描述人们的工作特点进行描述。

学习有关职业的单词。

学会谈论自己或他人的理想和以及谈论实现理想的方式。

本课呈现了本单元的主要教学内容，位于中间位置，承上启下，学好本课特别是对后面的学习起到一定的铺垫作用。

图片和录音磁带的内容与本课内容吻合，可以有效辅助教学。

也能激发学生学习的兴趣。

三、学情分析在教学过程中，对学情的了解是教师因材施教的关键。

我所教的初二（1）班学生基础较好，他们思维活跃、活泼好动，参与力较高，希望有突出表现，在八年级上学期已经学习了两册英语，学生有了一定的基础，本课的内容贴近学生生活实际，学生学习目的明确，反应较灵敏，学习英语兴趣较浓，学习较主动、自觉，具有一定的自学能力。

四、教师情况分析我从事英语教学十八年了，一直坚持学习研修，先后完成专科和本科的进修，不断提高自己的教育教学水平，曾被评为“任县名师”,在教学中，秉承“因材施教”“学以致用”和“以人为本”的教育理念。

五、教学目标导入1. 介绍自己小时候想要从事的职业，由此归纳出以前所学过的一些职业的英语表达方式：teacher, nurse, doctor, basketball player,runner, actor, actress…2.询问学生们想要从事的职业，从而引出句型：─What do you want to be when you grow up? ─I want to be a basketball player.3.学生们看幻灯片，引导学生们进行问答自己将来所喜欢的职业。
