新课标倡导通过“任务式”教学途径来培养学生综合运用语言的能力,所以课堂上的每个教学活动的目的要很明确,可控性要强。情景教学法的运用给课堂带来生机,便于学生去理解并乐于参与,提高兴趣度,提高教学效率。下面我以How often do you exercise?这一课的几个片段为例,来谈谈个人的几点浅见。

片段一:导入设计

教学单词及复习:

教师出示一段视频:《家有儿女》中刘梅給全家检查牙齿的片段。

T:Look at the videos,please tell me who has healthy teeth?Who is unhealthy?

Ss:Liu Xing is healthy. His father is unhealthy.

T:Do you know why?

Ss:No.

T:Because he often eats junk food and he drinks coffee at least twice a day. Its bad for his health.

(教师出示单词:at least,junk food,coffee,health→healthy→unhealthy,并讲授。)

T:We should have a healthy life. But how to keep healthy?Lets play a pairwork with your partner.

教师出示下列句型:

A:What do you do on weekends?

B:I ...

A:How often do you exercise?

B:I ...

A:How often do you watch TV?

B:I ...

A:Do you use the Internet on weekends?

B:Yes .../No ...

A:How often do you eat junk food?

B:I ...

视频的导入会起到活跃课堂气氛、凝聚课堂魅力的作用,而且里面的人物也和学生的年龄相仿,会让学生更喜欢。视频导入的目的有两个:一是让学生集中注意力;二是借机引出新授单词,利用问题:How to keep healthy?来复习上节课的主要内容。这样的导入方式有其独特之处,能够让学生在具体情境中体验语言运用的技巧,而单纯的检查、复习会让学生感觉枯燥。所以,该视频的运用有一石多鸟的效果。

片段二:教学3a出示幻灯片

1.How often _____ they go to movies?

2._____ he eat junk food?

3.What _____ you usually do on weekends?

T:请同学们讨论上面的三句话,并讨论do与does的用法。

教师讲解do与does的用法:

1.do与does都是助动词,在句中起着辅助的作用,需要放在特殊疑问词之后。放在一般疑问句中时,需要根据主语的人称和数的变化来确定do或does。当人称为第三人称单数时,助动词用does。

2.与be动词的区别:be本身还是实意动词,而do与does则不是。

T:Please make a sentence by yourself using “do” or “does”.

教师要求完成课本3a部分的内容。

T:Show time. Please make the conversation with your partner.

教师引领学生再次回顾do与does的用法。

在3b练习完成后,会有学生忘记加do或does,或者不会运用等情况,教师出示了三个句子,让学生先自己讨论他们的用法,然后再讲解,最后完成练习并以展示对话的方式结束。整个过程依照循序渐进的形式:提出疑问—展示质疑—自主讨论—教师讲解—巩固练习来完成。而最后的回顾环节则是为了面向全体学生,让每个学生都能看到自己的进步。

片段三:教学Section B 1c,1d

T:I want to have a survey. Who often eats junk food?Please hand up.

S:...

T:Who hardly ever eats vegetables?

S:...

T:OK. Remember everyone should have a healthy life. Because health is the fundamentality of our body.

S:Haha ...

T:Now a reporter is talking about health with Bill and Tina. Lets listen carefully and find who is healthy and who is unhealthy.

教师采用多媒体出示图片:

Is Bill healthy? Yes. No. I dont know.

Is Tina healthy? Yes. No. I dont know.

T:Please listen again and finish 1d. (两遍听力)

Check the answers together.

T:Show time.

Please make a passage about Tina and Bill.

Like this:

Tina is healthy. She ___________________

Bill is unhealthy. He___________________

课本中听力部分的教学难度不大,学生能够顺利完成,只是在1d部分,由于填空较多,需要再播放一遍听力,这一点需要教师注意。完成后,我又设计了展示环节,目的是为了增强教学的拓展性。让学生在1d的基础上,编写一段关于Tina或Bill的短文,训练学生的听说能力以及总结知识的能力。

本环节通过训练学生的听力来巩固重难点。将听力试题分层设计,让不同层次的学生都能参与进来。听完后又设计了听后活动:Show time让学生编写一段关于Tina和Bill的短文。通过听后编对话,引导学生更好地内化语言知识。从听到说,层层递进,为下一步的写作教学做好了铺垫。

片段四:教学Section A 3c,Section B 1e

T:Keeping healthy is important for everyone. Do you know your friends life?Now lets have a survey.

教师出示表格。

T:Please ask a friend some questions about his or her life. And then tell him/her that he/she is healthy or unhealthy.

T:Show time. Please write down his or her life.

Like this:My friend is Lin Yu. He reads Eng-lish books every day. ______________. So his life is _______.

將课本Section A 3c与 Section B 1e 部分的内容进行了整合,设计成Group-work的形式加以练习,进一步复习巩固了关于健康生活的话题,目的是为了和后面的写作教学联系在一起。这样能更全面地锻炼学生的听、说、读、写能力,从而提高学生综合运用语言的能力。这个环节到这里已经有水到渠成的感觉了,重点是让学生将听、读、说的内容转换成文字。在不同的语境中让学生学会运用和创新。

以上是我个人教学中的一点经验之谈,希望大家多给意见批评指正。
