2学情分析
本节课的授课对象是小学四年级学生。四年级学生经过近两年的英语学习,有了简单的英语基础知识和听说读写的能力;同时,学生对英语学习有着较浓厚的兴趣,喜欢表达自己的观点,也具备初步的自主、合作、探究能力。21cnjy.com
3重点难点
1、通过拆音、拼音和分类等语音意识训练活动,引导学生进行发现式的学习,根据发音规则读出新词。
2、情感朗读小故事。
4教学过程
Step1：Warm　up
T:
Hello,
boys
and
girls.
Today
let’s
learn
English
together.
There
are
three
groups.

a
song.
(Teacher
plays
the
music
of
Phonics
Song.
Students
clap
the
hands
and
sing
the
song.
)
设计意图:通过分组竞赛,激发学生努力学习。运用“hard”的手势,铺垫本节课的整体情感。通过集声、形、音、义一体的字母发音歌曲的欣赏,营造出一种语音学习氛围的同时,复习巩固相关辅音的发音,为后面的语音练习环节做好准备。21·cn·jy·com

2：Presentation
1、创设情景,呈现含有字母ar和al的单词。
T:
Class,
Do
you
have
a
dream
Ss:
Yes!
T:What
should
we
do
for
our
dreams
Now
let’s
meet
our
new
friends--Mark
And
Chalk.
教师利用课件创设Mark
为了实现拥有一辆小轿车的梦想而努力在农场工作的情景,有序呈现目标单词“farmer”
“tall”
“arm”
“car”,
并将单词卡片贴在相应的蘑菇房里,教师给出小语段,学生朗读。接下来创设Chalk喜欢画画,想成为一名画家,并为之努力的情景,引出单词“small”
“ball”
“card”
“wall”。
T:
Class,
what
should
we
do
for
our
dreams
I
think
we
should
work
hark,
too.
Right
Ss:
Yes!
T:
Work
hard!
Ss:
Work
hard!
设计意图:通过课件形象生动地创设出Mark和Chalk分别为梦想努力工作,努力画画的情景,有序、合理地呈现目标词汇,并引出本节课的情感主线----为梦想而努力。
2、引导学生观察、感知并归纳出ar和al在单词中发长音/a:/和
/ :/的规则。
T:
Look
at
this
house,
please.
There
are
two
same
letters
in
every
word.
What
are
they
Ss:
They
are
“ar”
T:
What
does
“ar”
sound
Read
the
words,
please.
设计意图:引导学生通过归类观察,朗读体验,自己总结出“ar”的发音规律。授人以鱼不如授人以“渔”。教师示范发音,学生模仿。
接下来教师引导学生用同样的方法自己归纳出“al”在单词中发/ :/的规律。
3、Have
a
chant
with
“ar”.
T:
Let’s
have
a
chant
with
“ar”
.
First
time:
listen.
(
Teacher
plays
the
chant.
Students
clap
hands.
)
T
:
Now
let’s
chant
together.
设计意图:利用Flash动画,通过朗朗上口,节奏感强,有韵律的说唱,强化记忆。
4、Make
a
chant
with
“al”.
T:
Class,
I
can’t
find
a
video
for
“al”.
Can
you
help
me
make
a
chant
with
“al”
Ss:
Yes.
设计意图:歌谣过于简单不利于保持小学生的兴趣,因此有必要将模仿歌谣引向自主创新。在这里我采用挖空的形式,让学生创编新的歌谣,以调动他们学习的主动性。www.21-cn-jy.com
Step
3：Practice
1、Read
the
new
words
with
“ar”
and
“al”.
T:
We
just
learned
“ar”
sounds
……
Ss:
/a:/.
T:
Can
you
read
these
words
(
Teacher
shows
new
words
with
“ar”
.
Students
try
to
read
)
同样的方法试读含“al”的新单词。学生每读对一个,奖励本组一颗星星,达六颗星星后升级为一个月亮。
设计意图:利用语言正迁移进行此语音活动,举一反三,触类旁通,有助于学生直拼能力的培养。
2、Read,
listen
and
number.
3、Play
a
game:
try
to
spell.
T:
Class,
let’s
play
a

“ar”
or
“al”,
then
spell
the
word.
Clear
Ss:
Yes.
(
Teacher

the
new
words,
Students

and
spell
quickly.
)
4、Read
,look
and
write.
设计意图:课堂教学仅停留在语言知识和语音的呈现上是不够的,教师有针对性地设计了适度、适量的拼写活动来检测学生的掌握情况。让他们自主拼读,对掌握单词的发音起到了较好的支架作用

(
CAI
)
设计意图:沿着本节课的为梦想而努力的话题,我设计了一个丑小鸭的故事缩版,以绘图的形式出现,自然有效地拓展学生的语音活动。首先让学生整体感知故事,感悟语音,并带着问题去理解故事。
2、Read
the
story
with
partners.
T:
Now
find
a
partner.
Read
the
story

设计意图:通过有感情地故事朗读,训练学生的语感,提升语音。
T:
Look!
(Point
the
stars)
Class,
you
work
hard
this
lesson.
You
get
so
many
stars.
Are
you
happy
Y:
Yeah!
T:
We
work
hard!
Ss
:
We
are
happy
!
设计意图:本节课对学生的评价采取的是画星星的方法,达六颗星星后可自动升级为一个月亮。课的结束,哪个小组获胜显而易见。但在评价总结时,教师没有问获胜的是哪个小组,因为大家都在努力,老师就引导学生总结出:We
work
hard!
We
are
happy
!既契合刚才的故事主题,又使本节课的线索情感——为梦想而努力,得到了升华——我努力!我快乐!21教育网

6：Homework
1、Read
the
chant
with
your
friends.
2、Read
the
story
with
emotion.
3、Play
letter-games
with
your

设计意图:通过作业的布置,教师将对学生的语感培养延伸到了课外。
T:

I
have
to
say
goodbye
to
my
friends.
Remember
please:

设计意图:这是教师在课前教给学生们的一个表达自信的手势及用语。通过本节课的共同努力,他们完成了本节任务的学习,这是多么令人自豪!虽然本节课结束了,但为梦想而努力的精神大家得一直坚持下去!所以,在这样一个看似作秀的环节里,学生的情感却被激发得淋漓尽致。这也是我们的语音课想要的效果:情感中去学习语言。
