第一篇:中职英语基础2 unit 5教案
Unit 5 It’s time to change.(第一课时)
一、学情分析
授课对象为高一年级旅游专业的女生,英语基础参差不齐,学习积极性易调动但难以持久,所以在设计中充分利用这个优点,通过多种课堂组织形式来调动她们的积极性,设计不同难易度的任务,唤起英语学习的欲望,从而达到教学目标。
二、教材分析
本课时是教材《英语2》(基础模块 高教版)第五单元的第一课时,本单元主要是关于生活习惯以及改变不良习惯的话题,该话题与学生的生活联系密切,能引起学生的共鸣。第一课时的内容包括Lead-in & Listening and speaking两部分,主要内容是关于生活习惯及描述健康状况的形容词词汇和表达习惯爱好的对话。这些内容为整个单元的学习活动做语言的必要准备。

Step Two Word Study 1.Matching game
Let students choose the right adjectives to describe the pictures on the screen.Students work in individuals and then check the answers together.2.Discussion and match

Step Three
Listening 1.Pre-listening
Asking several students questions about doing outdoor activities: Do you often do outdoor activities or do you often stay at home? Now, there are two students Tom and Sara talking about what they will do this weekend.2.While-listening(1)Listen and answer questions

3.Post-listening
(1)Read and underline.Students read after the tape sentence by sentence, and then underline the sentences showing preferences.(2)Let Ss find out these sentences and teacher lists sentence structures in the blackboard.(设计意图:在句子的跟读中,使学生掌握关于谈论兴趣爱好的重点句型,为后面的说话做最基础的准备)
Step Four: Speaking
1.Practice and act: talk about weekend activities in pairs

3.学生教师巡视全班,聆听学生对话,并解答学生提出的问题。4.挑出几个学生在班上表演。

6.在黑板上写上January,Sunday,today,tomorrow,在每一个单词的第一个字母下面划线并指出一年中的月份和一星期中的每一天的单词首字母都要大写,而表示别的时间的单词不用大写。
语法:按照本单元中GRAMMAR的内容讲解一般过去时的方法。此外还可以参照以下内容进行更细致的讲解。一般过去时表示:
(1)过去某个特定时间发生,并且一下子就完成了的动作(即:非持续性动作),也可以表示(2)过去习惯性的动作。一般过去时不强调动作对现在的影响,只说明过去。(1)I had a word with Julia this morning.今天早晨,我跟朱丽亚说了几句话。
(2)He smoked many cigarettes a day until he gave up.他没有戒烟的那阵子,烟抽得可凶了。一般过去时常与表示过去的时间状语或从句连用,如:yesterday,last week,in 1993,at that time,once,during the war,before,a few days ago,when 等等。
句子中谓语动词是用一般过去时还是用现在完成时,取决于动作是否对现在有影响。Have you had your lunch? 你吃过午饭了吗?(意思是说你现在不饿吗?)Yes,I have.是的,我已经吃过了。(意思是说已经吃饱了,不想再吃了。)When did you have it? 你是什么时候吃的?(关心的是吃的动作发生在何时。)I had it about ten minutes ago.我是大约十分钟以前吃的。
used to do something 表示过去常做而现在已经停止了的习惯动作。I used to work fourteen hours a day.我过去常常一天干十四个小时。一般过去时的基本用法:
1.带有确定的过去时间状语时,要用过去时
如:yesterday(昨天)、two days ago„(两天前„„)、last year„(去年„)、the other day(前几天)、once upon a time(过去曾经)、just now(刚才)、in the old days(过去的日子里)、before liberation(解放前„)、When I was 8 years old(当我八岁时„)Did you have a party the other day?前几天,你们开了晚会了吗? Lei Feng was a good soldier.雷锋是个好战士。
※注意:在谈到已死去的人的情况时,多用过去时。2.表示过去连续发生的动作时,要用过去时
这种情况下,往往没有表示过去的时间状语,而通过上下文来表示。The boy opened his eyes for a moment, looked at the captain, and then died.那男孩把眼睛张开了一会儿,看看船长,然后就去世了。
3.表示过去一段时间内经常或反复的动作常与always,never等连用。Mrs.Peter always carried an umbrella.彼得太太过去老是带着一把伞。(只是说明她过去的动作,不表明她现在是否常带着伞。)Mrs.Peter always carries an umbrella.彼得太太老是带着伞。(说明这是她的习惯,表明她现在仍然还习惯总带着一把伞)I never drank wine.我以前从不喝酒。(不涉及到现在,不说明现在是否喝酒)4.如果强调已经终止的习惯时要用used to do He used to drink.他过去喝酒。(意味着他现在不喝酒了。喝酒这个动作终止了)I used to take a walk in the morning.我过去是在早晨散步。(意味着现在不在早晨散步了)I took a walk in the morning.我曾经在早晨散过步。(只是说明过去这一动作)5.有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时,这一点,我们中国学生往往出错,要特别注意!I didn’t know you were in Paris.我不知道你在巴黎。(因为在说话时,我已经知道你在巴黎了。这句话指的是说话之前,所以只能用过去时表示。实际上,这句话暗指:But now I know you are here.)I thought you were ill.我以为你病了呢。
(这句话应是在说话之前,我以为你病了。但是现在我知道你没病)辨别正误:
Li Ming studied English this morning 把此句变为一般疑问句(×)1.Did Li Ming studied English this morning?(动词应该用原形)(×)2.Does Li ming Study English this morning?(时态应该用原句子的时态)(×)3.Was Li Ming studied English this morning?(应该用一般动词,而不是be动词)(√)4.Did Li Ming study Enghish this morning?一般过去时的句子的谓语形式有: 肯定① be 分为was,were② v+ed 否定① was/were not ②didn’t+v 疑问① was/were+主②did+主+v 一般将来时和现在进行时初中已经有所涉及,教师可以根据书上的内容做简单复习。Unit4 Would You Like to Go Shopping with Me?

第五篇:中职电子技术基础教案
中职电子技术基础教案
中职电子技术基础教案
随着科学技术的发展,电子技术目前被广泛应用于各个领域,与其他学科相比,电子技术更注重对学生思维和创新意识的提高,注重提升学生的综合能力。电子技术教学课程主要包括“模拟电子技术”和“数字电子技术”两部分,这是一门理论与实践并重的技术课程。中职院校要大力改革电子技术传统教学模式,创新教学体制,调整教学,不仅要使学生掌握基础理论知识,掌握专业技能,锻炼学生的逻辑思维和独立分析问题、解决问题的能力,坚持以培养学生创新实践能力为主要目的,激发学生的学习积极性,根据教学实际调整教学内容和考核方式,创新电子技术教学模式。
1.教师专业素质有待提高,教学方式陈旧
目前中职院校教师的专业教学水平还较低,教学呈现滞后状态,教学内容陈旧,教师简单的根据教材死板的开展教学,使学生处于被动的状态,学生的主体性难以发挥。其次,教师不会使用多种形式开展教学,教学方法过于单一,对于多媒体教学设备使用不够充分。
2.理论教学与实践教学脱节
现在中职院校电子技术过于强调理论知识教学,而且理论教学与实践教学分开进行,教师先讲解相关课程理论知识,之后进行相应的实验教学,这种教学设置导致理论教学与实践教学联系不够紧密,二者距离较远,且课堂教学略显枯燥,电子技术教学效果欠佳。
3.学生文化基础较为薄弱
中职院校一般招生大多是针对高中毕业没有考上本科的学生,学生文化基础较为薄弱,对学习的自主性与兴趣不够,导致高职专业教育和电子技术教学效果不佳。
1.按照教学大纲开展教学
高职院校要根据教学大纲的要求,做好电子技术教学,教学内容既要涵盖重要的基础理论、基础技能,电子技术教师要结合现代科学技术发展情况,在教学中增加介绍现代电子技术的新内容,做好基础理论教学,学生在扎实掌握电子技术知识基础上发挥自己的主观能动性,用正确理论指导实践,教师在调整教学时要做到开拓学生视野。
2.营造优良的实践教学环境
电子技术教学是一门理论知识与实践教学相结合的学科,因此教师要注重培养学生的专业理论知识和电子技能,高职院校要加大投入,建设电子教室和电子技术训练室的建设,为学生提供良好的实践教学环境和实践操作演练的设备设施,教师要增加实践环节的教学力度,提高实践教学在教学课时中的比重。教师要把理论教学与实践有机结合起来,合理安排实践课程的内容,确保实践课的教学质量。
3.构建能力本位的课程体系
电子技术课程所包含的内容特别多,例如半导体二极管、三极管、集成运算放大器电路、信号产生电路等,教学难度很大,加之高职学生的文化基础较为薄弱,他们学习理论知识的兴趣不高,排斥枯燥的教学内容,但对实验性的知识很感兴趣。教师要根据学生特点,以提高学生能力为核心调整教学,以专业培养目标和就业指导思想为出发点,指导教学实践,培养学生的职业能力,构建以培养能力为中心的课程体系是十分必要的。
4.重视实践教学
电子技术的特性就是理论与实践并重,实验、设备操作练习是最基本的实践课程,是电子技术教学的重要组成部分,高职院校要重视实验,并积极组织有效的实验教学,教师要合理增加实践教学力度,提高实践教学内容。其次,开展实践教学时要遵循学生的学习和认知规律,讲究循序渐进、由简到难,教师要根据学生的实际情况因材施教,根据学生的知识水平,调整实验教学内容。例如在实验教学中,教师可以带学生了解电子器件,并理解其工作原理,培养学生的动手实践能力和创新能力。
5.充分运用信息技术开展教学
随着我国教育改革的深入,很多高职院校教学时都在运用信息技术开展教学,教师可以使用多媒体课件讲解电子技术知识,还可以建立网络学习的平台,例如QQ群、微信群等,在网络平台上教师可以发布电子技术学习知识,还可以在网络平台上布置学习任务等,可以促进师生交流,促进学生之间的沟通,互相帮助、互相提高。例如教师可以采用微课翻转课堂,以5V三端直流稳压电源为例,把5V三端直流稳压电源电路知识做成微课,内容包括电路连接过程、电路原理、各元件作用等,充分发挥学生的主动性与自觉性,强化学生的实践能力与动手操作能力。
6.深化校企合作
坚持工学结合、知行合一是中职院校教学的有效途径,高职院校要加强与企业的合作和对接,派遣学生去企业实践,促进学生对电子技术的实际使用,促进其熟练掌握电子设备的操作和使用,注重教育与生产劳动相结合,强化教育教学的职业性,促进学以致用,学生利用课余时间到相应合作点跟岗实习,在做中学、学中做,培养学生的创新创业能力。
电子技术是中职院校的重要教学内容,尤其现代信息技术发展形势良好,各行各业对电子技术的依赖很大,因此要做好电子技术人才的培养。
