小学双语课时教学设计案例
本节选取的双语微课设计案例，是用来讲授12-18分钟双语微课的，是大学三年级双语方向师范生设计的，尽管还比较稚嫩，但大体上体现了双语课时计划设计的基本要求，可以做抛砖引玉之用。
Knowing the Decimal
ONE：Teaching Objectives
1.Subject objectives
（1）Knowledge objectives
A.Students can recognize，read and write the decimal with one digit behind the decimal point.
B.Students can tell each part of a decimal.
C.Students can recognize，read and write the decimal with one digit behind the decimal point，and the decimal with integer part being zero or other natural numbers.
（2）Ability objectives
A.Students can apply the knowledge of decimal to solve the problems from our daily life.
B.Students canapply the method of learning decimal to other learning.
（3）Emotion objectives
A.Students can realize the meaning of decimal from real-life experience.
B.Students can realize the relationship between maths and real-life situation.
C.Students can learnthe methods of learning a new figure.
2.Language objectives
Students can listen，read and speak these words such as“decimal”，“point”，“integer”，“natural number”，“decimeter”and“meter”.
TWO：Teaching Emphasis and Difficulties
1.Students cantell each part of a decimal.
2.Students can recognize，read and write the decimal with one digit behind the decimal point，and the decimal with integer part being zero or other natural numbers.
THREE：Teaching Process
1.Warming up（T for teacher and S for student）
T：Class begins！How are you，my students，today？
S：I am fine，thank you，Miss Zhao.
T：Perfect，let's play a game.Take up your rulers，please.And then measure the length and width of your desk.Write down the results and tell me.
（Students take this measurement then hand up.）
S1：Miss Zhao，my results are as follows.The length of the desk is 5 decimeter and the width is 4 decimeter.
T：OK，very good.Sit down，please.
（Teacher writes the results in the blackboard.）
2.New lessons
（1）Knowing the decimal with the integer part being zero
T：This results are measured in the unit of decimeter.Now I want to measure them in meter，what does 5 decimeter equal to？And what about 4 decimeter？Who can have a guess？
S：Maybe...
T：You are very fond of learning.5 decimeter is five tenth meter.In the same way，4 decimeter is four tenth meter.Five tenth meter is 0.5 meter，0.5 is read in this way，one point five.Four tenth meter is 0.4 meter，0.4 is read in this way，one point four.
T：Who can tell me how you explain these？
S：I divide 1 meter to 10 parts，then every part of it is 1 decimeter，1 decimeter is one tenth meter，and also 0.1 meter.
T：Wonderful！Let's give him/her a big hand！
Some tenth is 0.Some—REMEMBER IT.
（2）Knowing the decimal with the integer part not being zero
（Show the pictures of goods prices）
T：One day，I went to the supermarket，and see many goods in the window pane.
Look！Can you write this price in the form of Yuan unit？
Think it carefully，in the 1 Yuan 2 Jiao，how much does 2 Jiao mean for Yuan？And then how much is 1 Yuan 2 Jiao？
S：I can try the 1 Yuan and 2 Jiao.I think I can divide 1 Yuan into 10 Jiao，and 2 Jiao is 2 tenth Yuan，and account for 0.2 Yuan.So totally is 1.2 Yuan.
T：Yes，how smart you are！1.2 Yuan can read one point two Yuan.
What about 3 Yuan and 5 Jiao？
S：I can try！I think I can divide the 3 Yuan and 5 Jiao.5 Jiao is 5 tenth Yuan，and 5 Jiao account for 0.5 yuan.So the total is 3.5 Yuan.
T：Good job！I think you have understood the key to the knowledge.
Who can try some others？
S：...
（3）Knowing the name of every parts in the decimal
T：Before this class we have learned many numbers，such as 1，2，3，4，5，6，7，8，9...They are natural number，especially 0 is also natural number.And they are also integers.
In this class we learn 0.5，0.4，1.2，3.5.They are alldecimals.The point in the figure is called decimal point.The left part of the decimal point is integer part and the right part of it is decimal part.
Write：1，2，3，4，5，6，7，8，9...natural number，integer
0.5，0.4，1.2，3.5...decimal
T：Now try to read the decimals.For example，1.2.Who can have a try？
S：The 1 is integer part，the“.”is decimal point，and the 5 is decimal part.
T：Wonderful！Now you can try to say it in pairs.
S：...
Four：Summary
T：There are many decimals in our daily life.For example，
The average height of Grade 3 students is 1.2 meter.
The average height of babies is 0.5 meter.
The cost of a chewing gum is 3.5 Yuan.
You can apply the decimal knowledge to you daily life.

该双语微课设计方案中教学目标明确，重点难点包含在教学目标中。围绕教学目标展开教学进程，教学结构层次分明、思路清晰、循序渐进，符合学生认知发展水平。
课题是“认识小数”。首先，教学以游戏开始，让学生测量自己课桌长和宽。这样可以在开始上课时，迅速地集中学生的注意力，并能引发学生学习的兴趣。其次，把教学内容分为两部分，第一部分是整数部分是零的小数，即类似于0.5的小数；另一部分是整数部分是自然数的小数，即类似于1.3的小数。这节课的重点是学生能够了解小数各个部分的写法，组成结构以及所代表的意义。难点是认识整数部分是自然数的复杂多位小数，即比较大的小数（比如：10.34）。
这节课的缺点在于内容不够充实，有点为了目标而填塞内容的感觉，所举的例子本身大多缺乏逻辑性。为了追求“数学要联系生活”的新课改目标，把去商场买东西这个事例作为唯一的“实际”，没有创新意义，需要探索新的实例。
